General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are
used as test pins or to reduce noise. If something is connected to the NC pins, the
operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins
are in their open states, intermediate levels are induced by noise in the vicinity, a passthrough current flows internally, and a malfunction may occur.
3. Processing before Initialization
Note: When power is first supplied, the product's state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the
chip and a low level is input on the reset pin. During the period where the states are
undefined, the register settings and the output state of each pin are also undefined. Design
your system so that it does not malfunction because of processing while it is in this
undefined state. For those products which have a reset function, reset the LSI immediately
after the power supply has been turned on.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers
may have been be allocated to these addresses. Do not access these registers; the system's
operation is not guaranteed if they are accessed.

Description of Numbers and Symbols
Aspects of the notations for register names, bit names, numbers, and symbolic names in this
manual are explained below.
(1) Overall notation
In descriptions involving the names of bits and bit fields within this manual, the modules and
registers to which the bits belong may be clarified by giving the names in the forms
"module name"."register name"."bit name" or "register name"."bit name".
(2) Register notation
The style "register name"_"instance number" is used in cases where there is more than one
instance of the same function or similar functions.
[Example] CMCSR_0: Indicates the CMCSR register for the compare-match timer of channel 0.
(3) Number notation
Binary numbers are given as B'nnnn (B' may be omitted if the number is obviously binary),
hexadecimal numbers are given as H'nnnn or 0xnnnn, and decimal numbers are given as nnnn.
[Examples] Binary:
B'11 or 11
Hexadecimal: H'EFA0 or 0xEFA0
Decimal:
1234
(4) Notation for active-low
An overbar on the name indicates that a signal or pin is active-low.
[Example] WDTOVF
(4)
(2)
14.2.2 Compare Match Control/Status Register_0, _1 (CMCSR_0, CMCSR_1)
CMCSR indicates compare match generation, enables or disables interrupts, and selects the counter
input clock. Generation of a WDTOVF signal or interrupt initializes the TCNT value to 0.
14.3 Operation
14.3.1 Interval Count Operation
When an internal clock is selected with the CKS1 and CKS0 bits in CMCSR and the STR bit in
CMSTR is set to 1, CMCNT starts incrementing using the selected clock. When the values in
CMCNT and the compare match constant register (CMCOR) match, CMCNT is cleared to H'0000
and the CMF flag in CMCSR is set to 1. When the CKS1 and CKS0 bits are set to B'01 at this time,
a f/4 clock is selected.

SH7262/7264 Features
This LSI is a single-chip RISC (reduced instruction set computer) microcontroller that includes a
Renesas-original RISC CPU as its core, and the peripheral functions required to configure a
system.
The CPU in this LSI is an SH-2A CPU, which provides upward compatibility for SH-1, SH-2, and
SH-2E CPUs at object code level. It has a RISC-type instruction set, superscalar architecture, and
Harvard architecture, for superior rates of instruction execution. In addition, an independent 32-bit
internal-bus architecture enhances data processing power. This CPU brings the user the ability to
set up high-performance systems with strong functionality at less expense than was achievable
with previous microcontrollers, and is even able to handle realtime control applications requiring
high-speed characteristics.
This LSI has a floating-point unit and cache. In addition, this LSI includes on-chip peripheral
functions necessary for system configuration, such as a 64-Kbyte RAM for high-speed operation,
a 1-Mbyte or 640-Kbyte large-capacity RAM (32-Kbytes for 1-Mbyte and 320-Kbytes for 640Kbyte versions are shared by the data-retention RAM), multi-function timer pulse unit 2, compare
match timer, realtime clock, serial communication interface with FIFO, I2C bus interface 3, serial
sound interface, serial I/O with FIFO, controller area network interface*2, IEBusTM*1 controller*2,
Renesas SPDIF interface, CD-ROM decoder , A/D converter, NAND flash memory controller,
USB 2.0 host/function, video display controller 3, sampling rate converter, SD host interface,
decompression unit, motor control PWM timer, and interrupt controller modules, and general I/O
ports.
This LSI also provides an external memory access support function to enable direct connection to
various memory devices or peripheral LSIs. These on-chip functions significantly reduce costs of
designing and manufacturing application systems.
The features of this LSI are listed in table 1.1.
Notes: 1. IEBus (Inter Equipment Bus) is a trademark of Renesas Electronics Corporation.

Register Configuration
The register set consists of sixteen 32-bit general registers, four 32-bit control registers, and four
32-bit system registers.
2.1.1
General Registers
Figure 2.1 shows the general registers.
The sixteen 32-bit general registers are numbered R0 to R15. General registers are used for data
processing and address calculation. R0 is also used as an index register. Several instructions have
R0 fixed as their only usable register. R15 is used as the hardware stack pointer (SP). Saving and
restoring the status register (SR) and program counter (PC) in exception handling is accomplished
by referencing the stack using R15.

Control Registers
The control registers consist of four 32-bit registers: the status register (SR), the global base
register (GBR), the vector base register (VBR), and the jump table base register (TBR).
The status register indicates instruction processing states.
The global base register functions as a base address for the GBR indirect addressing mode to
transfer data to the registers of on-chip peripheral modules.
The vector base register functions as the base address of the exception handling vector area
(including interrupts).
The jump table base register functions as the base address of the function table area.

System Registers
The system registers consist of four 32-bit registers: the high and low multiply and accumulate
registers (MACH and MACL), the procedure register (PR), and the program counter (PC). MACH
and MACL store the results of multiply or multiply and accumulate operations. PR stores the
return address from a subroutine procedure. PC points four bytes ahead of the current instruction
and controls the flow of the processing.

Register Banks
For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and
system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried
out using a register bank. The register contents are automatically saved in the bank after the CPU
accepts an interrupt that uses a register bank. Restoration from the bank is executed by issuing a
RESBANK instruction in an interrupt processing routine.
This LSI has 15 banks. For details, see the SH-2A, SH2A-FPU Software Manual and section 7.8,
Register Banks.

Data Formats
2.2.1
Data Format in Registers
Register operands are always longwords (32 bits). If the size of memory operand is a byte (8 bits)
or a word (16 bits), it is changed into a longword by expanding the sign-part when loaded into a
register.

2.2.2
Data Formats in Memory
Memory data formats are classified into bytes, words, and longwords. Memory can be accessed in
8-bit bytes, 16-bit words, or 32-bit longwords. A memory operand of fewer than 32 bits is stored
in a register in sign-extended or zero-extended form.
A word operand should be accessed at a word boundary (an even address of multiple of two bytes:
address 2n), and a longword operand at a longword boundary (an even address of multiple of four
bytes: address 4n). Otherwise, an address error will occur. A byte operand can be accessed at any
address.
Only big-endian byte order can be selected for the data format.
Data formats in memory are shown in figure 2.5.

Section 2 CPU
Immediate Data Format
Byte (8-bit) immediate data is located in an instruction code. Immediate data accessed by the
MOV, ADD, and CMP/EQ instructions is sign-extended and handled in registers as longword
data. Immediate data accessed by the TST, AND, OR, and XOR instructions is zero-extended and
handled as longword data. Consequently, AND instructions with immediate data always clear the
upper 24 bits of the destination register.
20-bit immediate data is located in the code of a MOVI20 or MOVI20S 32-bit transfer instruction.
The MOVI20 instruction stores immediate data in the destination register in sign-extended form.
The MOVI20S instruction shifts immediate data by eight bits in the upper direction, and stores it
in the destination register in sign-extended form.
Word or longword immediate data is not located in the instruction code, but rather is stored in a
memory table. The memory table is accessed by an immediate data transfer instruction (MOV)
using the PC relative addressing mode with displacement.
See examples given in section 2.3.1 (10), Immediate Data.

Instruction Features
2.3.1
RISC-Type Instruction Set
Instructions are RISC type. This section details their functions.
(1)
16-Bit Fixed-Length Instructions
Basic instructions have a fixed length of 16 bits, improving program code efficiency.
(2)
32-Bit Fixed-Length Instructions
The SH-2A additionally features 32-bit fixed-length instructions, improving performance and ease
of use.
(3)
One Instruction per State
Each basic instruction can be executed in one cycle using the pipeline system.
(4)
Data Length
Longword is the standard data length for all operations. Memory can be accessed in bytes, words,
or longwords. Byte or word data in memory is sign-extended and handled as longword data.
Immediate data is sign-extended for arithmetic operations or zero-extended for logic operations. It
is also handled as longword data.

instruction.

Note: @(disp, PC) accesses the immediate data.
(5)
Load-Store Architecture
Basic operations are executed between registers. For operations that involve memory access, data
is loaded to the registers and executed (load-store architecture). Instructions such as AND that
manipulate bits, however, are executed directly in memory.

Section 2 CPU
Delayed Branch Instructions
With the exception of some instructions, unconditional branch instructions, etc., are executed as
delayed branch instructions. With a delayed branch instruction, the branch is taken after execution
of the instruction immediately following the delayed branch instruction. This reduces disturbance
of the pipeline control when a branch is taken.
In a delayed branch, the actual branch operation occurs after execution of the slot instruction.
However, instruction execution such as register updating excluding the actual branch operation, is
performed in the order of delayed branch instruction delay slot instruction. For example, even
though the contents of the register holding the branch destination address are changed in the delay
slot, the branch destination address remains as the register contents prior to the change.

(7)
Unconditional Branch Instructions with No Delay Slot
The SH-2A additionally features unconditional branch instructions in which a delay slot
instruction is not executed. This eliminates unnecessary NOP instructions, and so reduces the code
size.
(8)
Multiply/Multiply-and-Accumulate Operations
16-bit 16-bit 32-bit multiply operations are executed in one to two cycles. 16-bit 16-bit +
64-bit 64-bit multiply-and-accumulate operations are executed in two to three cycles. 32-bit
32-bit 64-bit multiply and 32-bit 32-bit + 64-bit 64-bit multiply-and-accumulate
operations are executed in two to four cycles.
(9)
T Bit
The T bit in the status register (SR) changes according to the result of the comparison. Whether a
conditional branch is taken or not taken depends upon the T bit condition (true/false). The number
of instructions that change the T bit is kept to a minimum to improve the processing speed.

(10) Immediate Data
Byte immediate data is located in an instruction code. Word or longword immediate data is not
located in instruction codes but in a memory table. The memory table is accessed by an immediate
data transfer instruction (MOV) using the PC relative addressing mode with displacement.
With the SH-2A, 17- to 28-bit immediate data can be located in an instruction code. However, for
21- to 28-bit immediate data, an OR instruction must be executed after the data is transferred to a
register.

(11) Absolute Address
When data is accessed by an absolute address, the absolute address value should be placed in the
memory table in advance. That value is transferred to the register by loading the immediate data
during the execution of the instruction, and the data is accessed in register indirect addressing
mode.
With the SH-2A, when data is referenced using an absolute address not exceeding 28 bits, it is also
possible to transfer immediate data located in the instruction code to a register and to reference the
data in register indirect addressing mode. However, when referencing data using an absolute
address of 21 to 28 bits, an OR instruction must be used after the data is transferred to a register.

When data is accessed by 16-bit or 32-bit displacement, the displacement value should be placed

Notes: 1. Instruction execution cycles: The execution cycles shown in the table are minimums. In
practice, the number of instruction execution states will be increased in cases such as
the following:
a. When there is a conflict between an instruction fetch and a data access
b. When the destination register of a load instruction (memory register) is the same
as the register used by the next instruction.
2. Depending on the operand size, displacement is scaled by 1, 2, or 4. For details,
refer to the SH-2A, SH2A-FPU Software Manual.

Notes: 1. Instruction execution cycles: The execution cycles shown in the table are minimums. In
practice, the number of instruction execution states in cases such as the following:
a. When there is a conflict between an instruction fetch and a data access
b. When the destination register of a load instruction (memory register) is the same
as the register used by the next instruction.
* In the event of bank overflow, the number of cycles is 19.

Section 2 CPU
Reset State
In the reset state, the CPU is reset. There are two kinds of reset, power-on reset and manual reset.
(2)
Exception Handling State
The exception handling state is a transient state that occurs when exception handling sources such
as resets or interrupts alter the CPU’s processing state flow.
For a reset, the initial values of the program counter (PC) (execution start address) and stack
pointer (SP) are fetched from the exception handling vector table and stored; the CPU then
branches to the execution start address and execution of the program begins.
For an interrupt, the stack pointer (SP) is accessed and the program counter (PC) and status
register (SR) are saved to the stack area. The exception service routine start address is fetched
from the exception handling vector table; the CPU then branches to that address and the program
starts executing, thereby entering the program execution state.
(3)
Program Execution State
In the program execution state, the CPU sequentially executes the program.
(4)
Power-Down State
In the power-down state, the CPU stops operating to reduce power consumption. The SLEEP
instruction places the CPU in sleep mode, software standby mode, or deep standby mode.
(5)
Bus-Released State
In the bus-released state, the CPU releases bus to a device that has requested it.

Floating-Point Format
A floating-point number consists of the following three fields:
Sign (s)
Exponent (e)
Fraction (f)

The exponent is expressed in biased form, as follows:
e = E + bias
The range of unbiased exponent E is Emin – 1 to Emax + 1. The two values Emin – 1 and Emax + 1 are
distinguished as follows. Emin – 1 indicates zero (both positive and negative sign) and a
denormalized number, and Emax + 1 indicates positive or negative infinity or a non-number (NaN).
Table 3.1 shows Emin and Emax values.

If E = Emax + 1 and f = 0, v = (–1)s (infinity) [positive or negative infinity]
If Emin E Emax , v = (–1)s2E (1.f) [normalized number]
If E = Emin – 1 and f 0, v = (–1)s2Emin (0.f) [denormalized number]
If E = Emin – 1 and f = 0, v = (–1)s0 [positive or negative zero]

Non-Numbers (NaN)
Figure 3.3 shows the bit pattern of a non-number (NaN). A value is NaN in the following case:
Sign bit: Don't care
Exponent field: All bits are 1
Fraction field: At least one bit is 1
The NaN is a signaling NaN (sNaN) if the MSB of the fraction field is 1, and a quiet NaN (qNaN)
if the MSB is 0.

N = 1: sNaN
N = 0: qNaN
Figure 3.3 Single-Precision NaN Bit Pattern
An sNaN is input in an operation, except copy, FABS, and FNEG, that generates a floating-point
value.
When the EN.V bit in FPSCR is 0, the operation result (output) is a qNaN.
When the EN.V bit in FPSCR is 1, an invalid operation exception will generate FPU exception
processing. In this case, the contents of the operation destination register are unchanged.
If a qNaN is input in an operation that generates a floating-point value, and an sNaN has not been
input in that operation, the output will always be a qNaN irrespective of the setting of the EN.V bit
in FPSCR. An exception will not be generated in this case.
The qNAN values as operation results are as follows:
Single-precision qNaN: H'7FBF FFFF
Double-precision qNaN: H'7FF7 FFFF FFFF FFFF
See the individual instruction descriptions for details of floating-point operations when a nonnumber (NaN) is input.

Denormalized Numbers
For a denormalized number floating-point value, the exponent field is expressed as 0, and the
fraction field as a non-zero value.
In the SH2A-FPU, the DN bit in the status register FPSCR is always set to 1, therefore a
denormalized number (source operand or operation result) is always flushed to 0 in a floatingpoint operation that generates a value (an operation other than copy, FNEG, or FABS).
When the DN bit in FPSCR is 0, a denormalized number (source operand or operation result) is
processed as it is. See the individual instruction descriptions for details of floating-point
operations when a denormalized number is input.

first. When an FPU exception on floating-point
operation occurs, the bits corresponding to the FPU
exception cause field and FPU exception flag field are
set to 1. The FPU exception flag field remains set to 1
until it is cleared to 0 by software.
As the bits corresponding to FPU exception enable

Floating-Point Communication Register (FPUL)
Information is transferred between the FPU and CPU via FPUL. FPUL is a 32-bit system register
that is accessed from the CPU side by means of LDS and STS instructions. For example, to
convert the integer stored in general register R1 to a single-precision floating-point number, the
processing flow is as follows:
R1 (LDS instruction) FPUL (single-precision FLOAT instruction) FR1

Section 3 Floating-Point Unit (FPU)
Rounding
In a floating-point instruction, rounding is performed when generating the final operation result
from the intermediate result. Therefore, the result of combination instructions such as FMAC will
differ from the result when using a basic instruction such as FADD, FSUB, or FMUL. Rounding is
performed once in FMAC, but twice in FADD, FSUB, and FMUL.
Which of the two rounding methods is to be used is determined by the RM bits in FPSCR.
FPSCR.RM[1:0] = 00: Round to Nearest
FPSCR.RM[1:0] = 01: Round to Zero
(1)
Round to Nearest
The operation result is rounded to the nearest expressible value. If there are two nearest
expressible values, the one with an LSB of 0 is selected.
If the unrounded value is 2Emax (2 – 2–P) or more, the result will be infinity with the same sign as the
unrounded value. The values of Emax and P, respectively, are 127 and 24 for single-precision, and
1023 and 53 for double-precision.
(2)
Round to Zero
The digits below the round bit of the unrounded value are discarded.
If the unrounded value is larger than the maximum expressible absolute value, the value will
become the maximum expressible absolute value.

FPU Exceptions
3.5.1
FPU Exception Sources
SH7262 Group, SH7264 Group
FPU exceptions may occur on floating-point operation instruction and the exception sources are as
follows:
FPU error (E): When FPSCR.DN = 0 and a denormalized number is input (No error occurs in
the SH2A-FPU)
Invalid operation (V): In case of an invalid operation, such as NaN input
Division by zero (Z): Division with a zero divisor
Overflow (O): When the operation result overflows
Underflow (U): When the operation result underflows
Inexact exception (I): When overflow, underflow, or rounding occurs
The FPU exception cause field in FPSCR contains bits corresponding to all of above sources E, V,
Z, O, U, and I, and the FPU exception flag and enable fields in FPSCR contain bits corresponding
to sources V, Z, O, U, and I, but not E. Thus, FPU errors cannot be disabled.
When an FPU exception occurs, the corresponding bit in the FPU exception cause field is set to 1,
and 1 is added to the corresponding bit in the FPU exception flag field. When an FPU exception
does not occur, the corresponding bit in the FPU exception cause field is cleared to 0, but the
corresponding bit in the FPU exception flag field remains unchanged.
3.5.2
FPU Exception Handling
FPU exception handling is initiated in the following cases:
FPU error (E): FPSCR.DN = 0 and a denormalized number is input (No error occurs in the
SH2A-FPU)
Invalid operation (V): FPSCR.Enable.V = 1 and invalid operation
Division by zero (Z): FPSCR.Enable.Z = 1 and division with a zero divisor
Overflow (O): FPSCR.Enable.O = 1 and instruction with possibility of operation result
overflow
Underflow (U): FPSCR.Enable.U = 1 and instruction with possibility of operation result
underflow
Inexact exception (I): FPSCR.Enable.I = 1 and instruction with possibility of inexact operation
result

SH7262 Group, SH7264 Group
Section 3 Floating-Point Unit (FPU)
These possibilities of each exceptional handling on floating-point operation are shown in the
individual instruction descriptions. All exception events that originate in the floating-point
operation are assigned as the same FPU exceptional handling event. The meaning of an exception
generated by floating-point operation is determined by software by reading from FPSCR and
interpreting the information it contains. Also, the destination register is not changed when FPU
exception handling operation occurs.
Except for the above, the FPU disables exception handling. In every processing, the bit
corresponding to source V, Z, O, U, or I is set to 1, and a default value is generated as the
operation result.
Invalid operation (V): qNaN is generated as the result.
Division by zero (Z): Infinity with the same sign as the unrounded value is generated.
Overflow (O):
When rounding mode = RZ, the maximum normalized number, with the same sign as the
unrounded value, is generated.
When rounding mode = RN, infinity with the same sign as the unrounded value is generated.
Underflow (U):
Zero with the same sign as the unrounded value is generated.
Inexact exception (I): An inexact result is generated.

Operation
4.3.1
Boot Mode 0
SH7262 Group, SH7264 Group
In boot mode 0, this LSI is booted from the memory connected to the CS0 space. In this mode,
this LSI operates as follows:
After the power-on reset is canceled, the initial value (execution start address) of the program
counter (PC) and the initial value of the stack pointer (SP) are fetched from the exception handling
vector table located in the memory connected to the CS0 space, then program execution is started.
4.3.2
Boot Modes 1 and 3
In boot modes 1 and 3, booting up is from serial flash memory, which is connected to channel 0 of
the Renesas serial peripheral interface. The flow of initiation in boot mode is as described below.
(1)
Execution from on-Chip ROM of the Program for Boot Initiation
After release from the power-on reset state, the CPU executes the boot initiation program that has
been stored in on-chip ROM (and is not publicly disclosed).
(2)
Transfer of the Loader Program
Starting with transfer from the respective first locations, the 8-KB loader program is transferred
from serial flash memory, which is connected to channel 0 of the Renesas serial peripheral
interface, to high-speed on-chip RAM.
Transfer proceeds at 1/2 of the rate of the bus clock (B) in boot mode 1 and at 1/4 of the rate of
the bus clock in boot mode 3. Decide on the boot mode in accord with the connected serial flash
memory.
Once transfer of the loader program has been completed, execution by the CPU jumps to highspeed on-chip RAM so that it can start executing the transferred loader program.
(3)
Transfer of an Application Program (as Desired)
The loader program employs the Renesas serial peripheral interface to transfer the data to be
deployed from serial flash memory to on-chip RAM or external RAM.

range to be used and the input clock type: the clock from crystal resonator or the clock for
USB 2.0 host/function module.
Three clocks generated independently
A CPU clock (I) for the CPU and cache; a peripheral clock (P) for the on-chip peripheral
modules; a bus clock (B = CKIO) for the external bus interface
Frequency change function
CPU and peripheral clock frequencies can be changed independently using the PLL (phase
locked loop) circuits and divider circuits within this module. Frequencies are changed by
software using frequency control register (FRQCR) settings.
Power-down mode control
The clock can be stopped in sleep mode, software standby mode, and deep standby mode, and
specific modules can be stopped using the module standby function. For details on clock
control in the power-down modes, see section 33, Power-Down Modes.

Section 5 Clock Pulse Generator
The blocks of this module function as follows:
(1)
Crystal Oscillator
The crystal oscillator is used in which the crystal resonator is connected to the XTAL/EXTAL pin
or USB_X1/USB_X2 pin. One of them is selected according to the clock operating mode.
(2)
Divider 1
Divider 1 divides the output from the crystal oscillator or the external clock input. The division
ratio depends on the clock operating mode.
(3)
PLL Circuit
PLL circuit multiplies the frequency of the output from the divider 1. The multiplication ratio
depends on the clock operating mode.
(4)
Divider 2
Divider 2 generates a clock signal whose operating frequency can be used for the CPU clock, the
peripheral clock, and the bus clock. The division ratio of the bus clock depends on the clock
operating mode. The division ratio of the CPU clock and the peripheral clock is set by the
frequency control register.
(5)
Clock Frequency Control Circuit
The clock frequency control circuit controls the clock frequency using the MD_CLK0 and
MD_CLK1 pins and the frequency control register (FRQCR).
(6)
Standby Control Circuit
The standby control circuit controls the states of the on-chip oscillation circuit and other modules
during clock switching, or sleep, software standby or deep standby mode.
In addition, the standby control register is provided to control the power-down mode of other
modules. For details on the standby control register, see section 33, Power-Down Modes.
(7)
Frequency Control Register (FRQCR)
The frequency control register (FRQCR) has control bits assigned for the following functions:
clock output/non-output from the CKIO pin during software standby mode and the frequency
division ratio of the CPU clock and the peripheral clock (P).

Mode 0
In mode 0, clock is input from the EXTAL pin or the crystal oscillator. The PLL circuit shapes
waveforms and multiples the frequency, and then supplies the clock to the LSI. The oscillating
frequency for the crystal resonator and EXTAL pin input clock ranges from 10 to 12 MHz.
The frequency range of CKIO is from 40 to 48 MHz. To reduce current supply, fix the
USB_X1 pin (connect it to a pull-up/down resistor, the power supply, or the ground) and open
the USB_X2 pin when the USB 2.0 host/function module is not used.
Mode 1
In mode 1, clock is input from the USB_X1 pin or the crystal oscillator. The external clock is
input through this pin and waveform is shaped in the PLL circuit. Then the frequency is
multiplied according to the frequency control register setting before the clock is supplied to the
LSI. The frequency of CKIO is the same as that of the input clock (USB_X1/crystal resonator)
(48 MHz). To reduce current supply, fix the EXTAL pin (connect it to a pull-up/down resistor,
the power supply, or the ground) and open the XTAL pin when the LSI is used in mode 1.

In mode 2, clock is input from the EXTAL pin or the crystal oscillator. The PLL circuit shapes
waveforms and multiples the frequency, and then supplies the clock to the LSI. The oscillating
frequency for the crystal resonator and EXTAL pin input clock ranges from 10 to 18 MHz.
The frequency range of CKIO is from 40 to 72 MHz. To reduce current supply, fix the
USB_X1 pin (connect it to a pull-up/down resistor, the power supply, or the ground) and open
the USB_X2 pin when the USB 2.0 host/function module is not used.
Mode 3
In mode 3, clock is input from the USB_X1 pin or the crystal oscillator. The external clock is
input through this pin and waveform is shaped in the PLL circuit. Then the frequency is
multiplied according to the frequency control register setting before the clock is supplied to the
LSI. The frequency of CKIO is the same as that of the input clock (USB_X1/crystal resonator)
multiplied by 4/3, (64 MHz). To reduce current supply, fix the EXTAL pin (connect it to a
pull-up/down resistor, the power supply, or the ground) and open the XTAL pin when the LSI
is used in mode 3.

Changing the Frequency
The frequency of the CPU clock (I) and peripheral clock (P) can be changed by changing the
division rate of divider. The division rate can be changed by software through the frequency
control register (FRQCR).
5.5.1
Changing the Division Ratio
The division rate of divider can be changed by the following operation.
1. In the initial state, IFC1 to IFC0 B'01 or B'10 and PFC2 to PFC0 B'100 or B'011.
2. Set the desired value in the IFC1 to IFC0 and PFC2 to PFC0 bits. The values that can be set
are limited by the clock operating mode and the multiplication rate of PLL circuit. Note that if
the wrong value is set, this LSI will malfunction.
3. After the register bits (IFC1 to IFC0 and PFC2 to PFC0) have been set, the clock is supplied of
the new division ratio.
Note: When executing the SLEEP instruction after the frequency has been changed, be sure to
read the frequency control register (FRQCR) three times before executing the SLEEP
instruction.

Section 5 Clock Pulse Generator
In the Case of Using a Crystal Resonator
An example of the connection of crystal resonator is shown in figure 5.3.
Place the crystal resonator and capacitors (CL1 and CL2) as close to pins Xin and Xout as
possible. Furthermore, to avoid inductance so that oscillation is correct, use the points where the
capacitors are connected to the crystal resonator in common and do not place wiring patterns close
to these components.
Since the design of the user board is closely connected with the effective characteristics of the
crystal resonator, refer to the example of connection of the crystal resonator that is introduced in
this section and perform thorough evaluation on the user side as well. The rated value of the
crystal resonator will vary with the floating capacitances and so on of the crystal resonator and
mounted circuit, so proceed with decisions on the basis of full discussions with the maker of the
crystal resonator. Ensure that voltages applied to the clock pins do not exceed the maximum rated
values.
Although the feedback resistor is included in this LSI, an external feedback resistor may be
required in some cases. This depends on the characteristics of the crystal resonator.
Set the parameters (of resistors and capacitors) with thorough evaluation on the user side.

external clock from EXTAL (clock mode 0 and 2) or USB_X1 (clock mode 1 and 3), please wait
longer than the oscillation stabilizing time at the following cases, to keep the oscillation stabilizing
time of the PLL circuit.

Notes on Board Design
5.8.1
Note on Using a PLL Oscillation Circuit
In the PLLVcc and PLLVss connection pattern for the PLL, signal lines from the board power
supply pins must be as short as possible and pattern width must be as wide as possible to reduce
inductive interferences.
Since the analog power supply pins of the PLL are sensitive to the noise, the system may
malfunction due to inductive interference at the other power supply pins. To prevent such
malfunction, the analog power supply pins and the digital power supply pins Vcc and PVcc should
not supply the same resources on the board if at all possible.
Ensure that PLLVcc has the same electric potential as Vcc.

in IBNR of the interrupt controller is 1) and an interrupt that
uses a register bank has occurred and been accepted by the
CPU.

Also starts when qNaN or is input to the source for a floating

When exception handling starts, the CPU operates as follows:
(1)
Exception Handling Triggered by Reset
The initial values of the program counter (PC) and stack pointer (SP) are fetched from the
exception handling vector table (PC and SP are respectively the H'00000000 and H'00000004
addresses for power-on resets and the H'00000008 and H'0000000C addresses for manual resets).
See section 6.1.3, Exception Handling Vector Table, for more information. The vector base
register (VBR) is then initialized to H'00000000, the interrupt mask level bits (I3 to I0) of the
status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized to 0. The
BN bit in IBNR of the interrupt controller is also initialized to 0. The floating point status/control
register (FPSCR) is initialized to H'00040001 by a power-on reset. The program begins running
from the PC address fetched from the exception handling vector table.

SH7262 Group, SH7264 Group
Exception Handling Triggered by Address Errors, Register Bank Errors, Interrupts,
and Instructions
SR and PC are saved to the stack indicated by R15. In the case of interrupt exception handling
other than NMI with usage of the register banks enabled, general registers R0 to R14, control
register GBR, system registers MACH, MACL, and PR, and the vector table address offset of the
interrupt exception handling to be executed are saved to the register banks. In the case of
exception handling due to an address error, register bank error, NMI interrupt, or instruction,
saving to a register bank is not performed. When saving is performed to all register banks,
automatic saving to the stack is performed instead of register bank saving. In this case, an interrupt
controller setting must have been made so that register bank overflow exceptions are not accepted
(the BOVE bit in IBNR of the interrupt controller is 0). If a setting to accept register bank
overflow exceptions has been made (the BOVE bit in IBNR of the interrupt controller is 1),
register bank overflow exception will be generated. In the case of interrupt exception handling, the
interrupt priority level is written to the I3 to I0 bits in SR. In the case of exception handling due to
an address error or instruction, the I3 to I0 bits are not affected. The exception service routine start
address is then fetched from the exception handling vector table and the program begins running
from that address.
6.1.3
Exception Handling Vector Table
Before exception handling begins running, the exception handling vector table must be set in
memory. The exception handling vector table stores the start addresses of exception service
routines. (The reset exception handling table holds the initial values of PC and SP.)
All exception sources are given different vector numbers and vector table address offsets, from
which the vector table addresses are calculated. During exception handling, the start addresses of
the exception service routines are fetched from the exception handling vector table, which is
indicated by this vector table address.

Types of Reset
A reset is the highest-priority exception handling source. There are two kinds of reset, power-on
and manual. As shown in table 6.6, the CPU state is initialized in both a power-on reset and a
manual reset. The FPU state is initialized by a power-on reset, but not by a manual reset. On-chip
peripheral module registers except a few registers are also initialized by a power-on reset, but not
by a manual reset.

Section 6 Exception Handling
Power-On Reset
Power-On Reset by Means of RES Pin
When the RES pin is driven low, this LSI enters the power-on reset state. To reliably reset this
LSI, the RES pin should be kept at the low level for the duration of the oscillation settling time at
power-on or when in software standby mode (when the clock is halted), or at least 20-tcyc when
the clock is running. In the power-on reset state, the internal state of the CPU and all the on-chip
peripheral module registers are initialized. See appendix A, Pin States, for the status of individual
pins during the power-on reset state.
In the power-on reset state, power-on reset exception handling starts when the RES pin is first
driven low for a fixed period and then returned to high. The CPU operates as follows:
1. The initial value (execution start address) of the program counter (PC) is fetched from the
exception handling vector table.
2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table.
3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to
I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are
initialized to 0. The BN bit in IBNR of the interrupt controller is also initialized to 0. FPSCR is
initialized to H'00040001
4. The values fetched from the exception handling vector table are set in the PC and SP, and the
program begins executing.
Be certain to always perform power-on reset processing when turning the system power on.
(2)
Power-On Reset by Means of User Debugging Interface Reset Assert Command
When the user debugging interface reset assert command is set, this LSI enters the power-on reset
state. Power-on reset by means of the user debugging interface reset assert command is equivalent
to power-on reset by means of the RES pin. Setting the user debugging interface reset negate
command cancels the power-on reset state. The time required between the user debugging
interface reset assert command and the user debugging interface reset negate command is the same
as the time to keep the RES pin low to initiate a power-on reset. In the power-on reset state
generated by the user debugging interface reset assert command, setting the user debugging
interface reset negate command starts power-on reset exception handling. The CPU operates in the
same way as when a power-on reset was caused by the RES pin.

Power-On Reset Initiated by Watchdog Timer
When a setting is made for a power-on reset to be generated in watchdog timer mode of the
watchdog timer, and WTCNT of the watchdog timer overflows, this LSI enters the power-on reset
state.
In this case, WRCSR of the watchdog timer and FRQCR of the clock pulse generator are not
initialized by the reset signal generated by the watchdog timer.
If a reset caused by the RES pin or the user debugging interface reset assert command occurs
simultaneously with a reset caused by watchdog timer overflow, the reset caused by the RES pin
or the user debugging interface reset assert command has priority, and the WOVF bit in WRCSR
is cleared to 0. When power-on reset exception processing is started by the watchdog timer, the
CPU operates in the same way as when a power-on reset was caused by the RES pin.

Manual Reset
Manual Reset Initiated by Watchdog Timer
When a setting is made for a manual reset to be generated in watchdog timer mode of the
watchdog timer, and WTCNT of the watchdog timer overflows, this LSI enters the manual reset
state.
When manual reset exception processing is started by the watchdog timer, the CPU operates as
follows:
1. The initial value (execution start address) of the program counter (PC) is fetched from the
exception handling vector table.
2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table.
3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to
I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are
initialized to 0. The BN bit in IBNR of interrupt controller is also initialized to 0.
4. The values fetched from the exception handling vector table are set in the PC and SP, and the
program begins executing.

Note in Manual Reset
When a manual reset is generated, the bus cycle is retained, but if a manual reset occurs while the
bus is released or during burst transfer by the direct memory access controller, manual reset
exception handling will be deferred until the CPU acquires the bus. The CPU and the BN bit in
IBNR of the interrupt controller are initialized by a manual reset. The FPU and other modules are
not initialized.

Section 6 Exception Handling
Address Error Exception Handling
When an address error occurs, the bus cycle in which the address error occurred ends. When the
executing instruction then finishes, address error exception handling starts. The CPU operates as
follows:
1. The exception service routine start address which corresponds to the address error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction.
4. After jumping to the exception service routine start address fetched from the exception
handling vector table, program execution starts. The jump that occurs is not a delayed branch.

Register Bank Errors
6.4.1
Register Bank Error Sources
(1)
Bank Overflow
In the state where saving has already been performed to all register bank areas, bank overflow
occurs when acceptance of register bank overflow exception has been set by the interrupt
controller (the BOVE bit in IBNR of the interrupt controller is set to 1) and an interrupt that uses a
register bank has occurred and been accepted by the CPU.
(2)
Bank Underflow
Bank underflow occurs when an attempt is made to execute a RESBANK instruction while saving
has not been performed to register banks.

1. The exception service routine start address which corresponds to the register bank error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction for a bank overflow, and the start
address of the executed RESBANK instruction for a bank underflow.
To prevent multiple interrupts from occurring at a bank overflow, the priority level of the
interrupt that caused the bank overflow is written to the interrupt mask level bits (I3 to I0) of
the status register (SR).
4. After jumping to the exception service routine start address fetched from the exception

6.5
Interrupts
6.5.1
Interrupt Sources
The sources that start interrupt exception handling are divided into NMI, user debugging interface,
IRQ, PINT, and on-chip peripheral modules.
Each interrupt source is allocated a different vector number and vector table offset. See table 7.4
in section 7, Interrupt Controller, for more information on vector numbers and vector table address
offsets.

Section 6 Exception Handling
Interrupt Priority Level
The interrupt priority order is predetermined. When multiple interrupts occur simultaneously
(overlap), the interrupt controller determines their relative priorities and starts exception handling
according to the results.
The priority order of interrupts is expressed as priority levels 0 to 16, with priority 0 the lowest
and priority 16 the highest. The NMI interrupt has priority 16 and cannot be masked, so it is
always accepted. The priority level of user debugging interface interrupts is 15. Priority levels of
IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be set freely using
the interrupt priority registers 01, 02, and 05 to 22 (IPR01, IPR02, and IPR05 to IPR22) of the
interrupt controller as shown in table 6.9. The priority levels that can be set are 0 to 15. Level 16
cannot be set. See section 7.3.1, Interrupt Priority Registers 01, 02, 05 to 22 (IPR01, IPR02, IPR05
to IPR22), for details of IPR01, IPR02, and IPR05 to IPR22.

SH7262 Group, SH7264 Group
Interrupt Exception Handling
When an interrupt occurs, its priority level is ascertained by the interrupt controller. NMI is
always accepted, but other interrupts are only accepted if they have a priority level higher than the
priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR).
When an interrupt is accepted, interrupt exception handling begins. In interrupt exception
handling, the CPU fetches the exception service routine start address which corresponds to the
accepted interrupt from the exception handling vector table, and saves SR and the program counter
(PC) to the stack. In the case of interrupt exception handling other than NMI with usage of the
register banks enabled, general registers R0 to R14, control register GBR, system registers
MACH, MACL, and PR, and the vector table address offset of the interrupt exception handling to
be executed are saved in the register banks. In the case of exception handling due to an address
error, NMI interrupt, or instruction, saving is not performed to the register banks. If saving has
been performed to all register banks (0 to 14), automatic saving to the stack is performed instead
of register bank saving. In this case, an interrupt controller setting must have been made so that
register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the interrupt
controller is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE
bit in IBNR of the interrupt controller is 1), register bank overflow exception occurs. Next, the
priority level value of the accepted interrupt is written to the I3 to I0 bits in SR. For NMI,
however, the priority level is 16, but the value set in the I3 to I0 bits is H'F (level 15). Then, after
jumping to the start address fetched from the exception handling vector table, program execution
starts. The jump that occurs is not a delayed branch. See section 7.6, Operation, for further details
of interrupt exception handling.

SH7262 Group, SH7264 Group
Trap Instructions
When a TRAPA instruction is executed, trap instruction exception handling starts. The CPU
operates as follows:
1. The exception service routine start address which corresponds to the vector number specified
in the TRAPA instruction is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the TRAPA instruction.
4. After jumping to the exception service routine start address fetched from the exception
handling vector table, program execution starts. The jump that occurs is not a delayed branch.
6.6.3
Slot Illegal Instructions
An instruction placed immediately after a delayed branch instruction is called the “instruction
placed in a delay slot”. When the instruction placed in the delay slot is undefined code (including
FPU instructions and FPU-related CPU instructions in FPU module standby state), an instruction
that rewrites the PC, a 32-bit instruction, an RESBANK instruction, a DIVS instruction, or a
DIVU instruction, slot illegal exception handling starts when such kind of instruction is decoded.
When the FPU has entered a module standby state, the floating point operation instruction and
FPU-related CPU instructions are handled as undefined codes. If these instructions are placed in a
delay slot and then decoded, a slot illegal instruction exception handling starts.
The CPU operates as follows:
1. The exception service routine start address is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the jump address of the
delayed branch instruction immediately before the undefined code, the instruction that rewrites
the PC, the 32-bit instruction, the RESBANK instruction, the DIVS instruction, or the DIVU
instruction.
4. After jumping to the exception service routine start address fetched from the exception
handling vector table, program execution starts. The jump that occurs is not a delayed branch.

Section 6 Exception Handling
General Illegal Instructions
When an undefined code, including FPU instructions and FPU-related CPU instructions in FPU
module standby state, placed anywhere other than immediately after a delayed branch instruction,
i.e., in a delay slot, is decoded, general illegal instruction exception handling starts. When the FPU
has entered a module standby state, the floating point instruction and FPU-related CPU
instructions are handled as undefined codes. If these instructions are placed anywhere other than
immediately after a delayed branch instruction (i.e., in a delay slot) and then decoded, general
illegal instruction exception handling starts.
In general illegal instruction exception handling, the CPU handles general illegal instructions in
the same way as slot illegal instructions. Unlike processing of slot illegal instructions, however,
the program counter value stored is the start address of the undefined code.
6.6.5
Integer Division Exceptions
When an integer division instruction performs division by zero or the result of integer division
overflows, integer division instruction exception handling starts. The instructions that may become
the source of division-by-zero exception are DIVU and DIVS. The only source instruction of
overflow exception is DIVS, and overflow exception occurs only when the negative maximum
value is divided by 1. The CPU operates as follows:
1. The exception service routine start address which corresponds to the integer division exception
that occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
integer division instruction at which the exception occurred.
4. After jumping to the exception service routine start address fetched from the exception
handling vector table, program execution starts. The jump that occurs is not a delayed branch.

SH7262 Group, SH7264 Group
FPU Exceptions
An FPU exception handling is generated when the V, Z, O, U or I bit in the FPU exception enable
field (Enable) of the floating point status/control register (FPSCR) is set. This indicates the
occurrence of an invalid operation exception defined by the IEEE standard 754, a division-by-zero
exception, overflow (in the case of an instruction for which this is possible), underflow (in the
case of an instruction for which this is possible), or inexact exception (in the case of an instruction
for which this is possible).
The floating point operation instructions that may cause an FPU exception handling are FADD,
FSUB, FMUL, FDIV, FMAC, FCMP/EQ, FCMP/GT, FLOAT, FTRC, FCNVDS, FCNVSD, and
FSQRT.
An FPU exception handling is generated only when the corresponding FPU exception enable bit
(Enable) is set. When the FPU detects an exception source in floating point operation, FPU
operation is halted and generation of an FPU exception handling is reported to the CPU. When
exception handling is started, the CPU operations are as follows.
1. The start address of the exception service routine which corresponds to the FPU exception
handling that occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction.
4. After jumping to the exception service routine start address fetched from the exception
handling vector table, program execution starts. This jump is not a delayed branch.
The FPU exception flag field (Flag) of FPSCR is always updated regardless of whether or not an
FPU exception handling has been accepted, and remains set until explicitly cleared by the user
through an instruction. The FPU exception source field (Cause) of FPSCR changes each time a
floating point operation instruction is executed.
When the V bit in the FPU exception enable field (Enable) of FPSCR is set and the QIS bit in
FPSCR is also set, FPU exception handling is generated when qNAN or is input to a floating
point operation instruction source.

6.9
Usage Notes
6.9.1
Value of Stack Pointer (SP)
Section 6 Exception Handling
The value of the stack pointer must always be a multiple of four. If it is not, an address error will
occur when the stack is accessed during exception handling.
6.9.2
Value of Vector Base Register (VBR)
The value of the vector base register must always be a multiple of four. If it is not, an address error
will occur when the stack is accessed during exception handling.
6.9.3
Address Errors Caused by Stacking of Address Error Exception Handling
When the stack pointer is not a multiple of four, an address error will occur during stacking of the
exception handling (interrupts, etc.) and address error exception handling will start up as soon as
the first exception handling is ended. Address errors will then also occur in the stacking for this
address error exception handling. To ensure that address error exception handling does not go into
an endless loop, no address errors are accepted at that point. This allows program control to be
shifted to the address error exception service routine and enables error processing.
When an address error occurs during exception handling stacking, the stacking bus cycle (write) is
executed. During stacking of the status register (SR) and program counter (PC), the SP is
decremented by 4 for both, so the value of SP will not be a multiple of four after the stacking
either. The address value output during stacking is the SP value, so the address where the error
occurred is itself output. This means the write data stacked will be undefined.
6.9.4
Interrupt Control via Modification of Interrupt Mask Bits
When enabling interrupts by changing the Interrupt Mask bits (I3-I0) of the Status Register (SR)
using the LDC or LDC.L instructions, interrupts might not be accepted during the execution of the
5 instructions immediately after the LDC/LDC.L instruction.
Therefore, when enabling/disabling interrupts by changing the Interrupt Mask bits (I3-I0) of the
Status Register (SR) using LDC/LDC.L instructions, please place at least 5 instructions between
the interrupt-enable instruction and the interrupt-disable instruction.

Note before Exception Handling Begins Running
Before exception handling begins running, the exception handling vector table must be stored in a
memory, and the CPU must be able to access the memory. So, if the exception handling is
generated
Ex. 1: when the exception handling vector table is stored in an external address space, but the
settings of bus state controller and general I/O ports to access the external address space
have been not completed yet, or
Ex. 2: when the exception handling vector table is stored in the on-chip RAM, but the vector
base register (VBR) has been not changed to the on-chip RAM address yet,
the CPU fetches an unintended value as the execution start address, and starts executing programs
from unintended address.
(1)
Manual Reset
Before the settings necessary to access the external CS0 space are completed, the manual reset
should not be generated. When a manual reset is issued, the CPU fetches the program execution
start address from the manual reset vector table address offset (H'00000008), which is to say
always from the external CS0 space. Additionally, in the case that no memory is connected to the
external CS0 space in boot mode 1 to 3, the manual reset should not be generated.
(2)
NMI Interrupt
Before the exception handling vector table is stored in a memory and the settings necessary to
access the memory are completed, the NMI interrupt should not be generated. (Do not enable
interrupts on the 640 KB version.)
Specially in boot mode 1 to 3, the VBR is kept as the initial value H'00000000 in the period of the
boot operation (before the transfer of the loader program is completed and the CPU jumps to the
on-chip high-speed RAM). Before the VBR is changed or the settings necessary to access the
external address space are completed in the loader program, the NMI interrupt should not be
generated. (Do not enable interrupts on the 640 KB version.)
(3)
Interrupts Other Than NMI
Before the exception handling vector table is stored in a memory and the settings necessary to
access the memory are completed, the settings to permit the interrupts should not be done.

The Other Exceptions
Before the exception handling vector table is stored in a memory and the settings necessary to
access the memory are completed, the exception handling should not be generated.

Section 7 Interrupt Controller
Section 7 Interrupt Controller
The interrupt controller ascertains the priority of interrupt sources and controls interrupt requests
to the CPU. The interrupt controller registers set the order of priority of each interrupt, allowing
the user to process interrupt requests according to the user-set priority.
7.1
Features
16 levels of interrupt priority can be set.
By setting the twenty interrupt priority registers, the priorities of IRQ interrupts, PINT
interrupts, and on-chip peripheral module interrupts can be selected from 16 levels for request
sources.
NMI noise canceler function
An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt
exception service routine, the pin state can be checked, enabling it to be used as the noise
canceler function.
Register banks
This LSI has register banks that enable register saving and restoration required in the interrupt
processing to be performed at high speed.

IRQ Interrupt Request Register (IRQRR)
IRQRR is a 16-bit register that indicates interrupt requests from external input pins IRQ7 to IRQ0.
If edge detection is set for the IRQ7 to IRQ0 interrupts, writing 0 to the IRQ7F to IRQ0F bits after
reading IRQ7F to IRQ0F = 1 cancels the retained interrupts.

Section 7 Interrupt Controller
Interrupt Sources
There are five types of interrupt sources: NMI, user debugging interface, IRQ, PINT, and on-chip
peripheral modules. Each interrupt has a priority level (0 to 16), with 0 the lowest and 16 the
highest. When set to level 0, that interrupt is masked at all times.
7.4.1
NMI Interrupt
1-Mbyte version
The NMI interrupt has a priority level of 16 and is accepted at all times. NMI interrupt
requests are edge-detected, and the NMI edge select bit (NMIE) in interrupt control register 0
(ICR0) selects whether the rising edge or falling edge is detected.
Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets
the interrupt mask level bits (I3 to I0) in the status register (SR) to level 15.
640-Kbyte version
The NMI interrupt has a priority level of 16 and is accepted at all times when the NMI mask
bit (NMIM) in interrupt control register 0 (ICR0) is enabled. NMI interrupt requests are edgedetected, and the NMI edge select bit (NMIE) in ICR0 selects whether the rising edge or
falling edge is detected.
Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets
the interrupt mask level bits (I3 to I0) in the status register (SR) to level 15.
When the NMIM bit in ICR0 is set to 1 (NMI interrupt request is masked), the NMI interrupt
is not generated, however the NMI edge corresponding to NMIE bit of ICR0 is detected and
the NMI interrupt request is retained until the interrupt request is accepted. The status of the
interrupt request can be checked by reading the NMI interrupt request bit (NMIF) in the ICR0.
If 0 is written to the NMIM bit (NMI interrupt request is enabled) when the NMIF bit is set to
1, the NMI interrupt request that is retained is accepted. Once the NMIM bit is set to 0 (NMI
interrupt request is enabled), the NMIM bit cannot be set to 1 again, because only 0 can be
written to the NMIM bit. When the NME bit is changed, the NMI interrupt request that is
retained is cleared.
R01UH0134EJ0400 Rev. 4.00
Sep 24, 2014
Page 173 of 2108
Section 7 Interrupt Controller
SH7262 Group, SH7264 Group
When canceling software standby mode by the NMI interrupt, set the NMIM bit to 0 to enable
the NMI interrupt request after confirming that the NMI interrupt request has been cleared in
the NMIF. If software standby mode is entered when the NMIM bit is 1 (NMI interrupt request
is masked), the NMI interrupt cannot cancel software standby mode. In this case, the NMI
edge cannot be detected in software standby mode and the NMI interrupt is not generated even
if software standby mode is canceled by cancel source other than NMI. When the NMI pin
keeps level (low level after the falling edge or high level after the rising edge) in software
standby mode until software standby mode is canceled by cancel source other than NMI (until
the clock is initiated after the oscillation settling), that edge of the NMI in software standby
mode can be detected.
When deep standby mode is entered, deep standby mode is canceled by the NMI interrupt
regardless of the NMI mask bit setting. NMIM bit is initialized by a power-on reset after
canceling deep standby mode.
When a sleep instruction is to be executed after 0 has been written to the NMIM bit (enabling
the NMI), read the value of the NMIM bit before executing the sleep instruction.
7.4.2
User Debugging Interface Interrupt
The user debugging interface interrupt has a priority level of 15, and occurs at serial input of a
user debugging interface interrupt instruction. User debugging interface interrupt requests are
edge-detected and retained until they are accepted. The user debugging interface interrupt
exception handling sets the I3 to I0 bits in SR to level 15. For user debugging interface interrupts,
see section 34, User Debugging Interface.
7.4.3
IRQ Interrupts
IRQ interrupts are input from pins IRQ7 to IRQ0. For the IRQ interrupts, low-level, falling-edge,
rising-edge, or both-edge detection can be selected individually for each pin by the IRQ sense
select bits (IRQ71S to IRQ01S and IRQ70S to IRQ00S) in interrupt control register 1 (ICR1). The
priority level can be set individually in a range from 0 to 15 for each pin by interrupt priority
registers 01 and 02 (IPR01 and IPR02).
When using low-level sensing for IRQ interrupts, an interrupt request signal is sent to the interrupt
controller while the IRQ7 to IRQ0 pins are low. An interrupt request signal is stopped being sent
to the interrupt controller when the IRQ7 to IRQ0 pins are driven high. The status of the interrupt
requests can be checked by reading the IRQ interrupt request bits (IRQ7F to IRQ0F) in the IRQ
interrupt request register (IRQRR).
When using edge-sensing for IRQ interrupts, an interrupt request is detected due to change of the
IRQ7 to IRQ0 pin states, and an interrupt request signal is sent to the interrupt controller. The
result of IRQ interrupt request detection is retained until that interrupt request is accepted.

Sep 24, 2014
SH7262 Group, SH7264 Group
Section 7 Interrupt Controller
Whether IRQ interrupt requests have been detected or not can be checked by reading the IRQ7F to
IRQ0F bits in IRQRR. Writing 0 to these bits after reading them as 1 clears the result of IRQ
interrupt request detection.
The IRQ interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the
accepted IRQ interrupt.
When returning from IRQ interrupt exception service routine, execute the RTE instruction after
confirming that the interrupt request has been cleared by the IRQ interrupt request register
(IRQRR) so as not to accidentally receive the interrupt request again.
7.4.4
PINT Interrupts
PINT interrupts are input from pins PINT7 to PINT0. Input of the interrupt requests is enabled by
the PINT enable bits (PINT7E to PINT0E) in the PINT interrupt enable register (PINTER). For
the PINT7 to PINT0 interrupts, low-level or high-level detection can be selected individually for
each pin by the PINT sense select bits (PINT7S to PINT0S) in interrupt control register 2 (ICR2).
A single priority level in a range from 0 to 15 can be set for all PINT7 to PINT0 interrupts by bits
15 to 12 in interrupt priority register 05 (IPR05).
When using low-level sensing for the PINT7 to PINT0 interrupts, an interrupt request signal is
sent to the interrupt controller while the PINT7 to PINT0 pins are low. An interrupt request signal
is stopped being sent to the interrupt controller when the PINT7 to PINT0 pins are driven high.
The status of the interrupt requests can be checked by reading the PINT interrupt request bits
(PINT7R to PINT0R) in the PINT interrupt request register (PIRR). The above description also
applies to when using high-level sensing, except for the polarity being reversed. The PINT
interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the PINT interrupt.
When returning from IRQ interrupt exception service routine, execute the RTE instruction after
confirming that the interrupt request has been cleared by the PINT interrupt request register
(PIRR) so as not to accidentally receive the interrupt request again.

On-Chip Peripheral Module Interrupts
On-chip peripheral module interrupts are generated by the following on-chip peripheral modules:
Direct memory access controller
USB 2.0 host/function module
Video display controller 3
Compare match timer
Bus state controller
Watchdog timer
Multi-function timer pulse unit 2
Motor control PWM timer
A/D converter
Serial sound interface
Renesas SPDIF interface
I2C bus interface 3
Serial communication interface with FIFO
Serial I/O with FIFO
Renesas serial peripheral interface
Controller area network
IEBusTM controller
CD-ROM decoder
NAND flash memory controller
SD host interface
Realtime clock
Sampling rate converter
Decompression unit
As every source is assigned a different interrupt vector, the source does not need to be identified in
the exception service routine. A priority level in a range from 0 to 15 can be set for each module
by interrupt priority registers 05 to 22 (IPR05 to IPR22). The on-chip peripheral module interrupt
exception handling sets the I3 to I0 bits in SR to the priority level of the accepted on-chip
peripheral module interrupt.

Section 7 Interrupt Controller
Interrupt Exception Handling Vector Table and Priority
Table 7.4 lists interrupt sources and their vector numbers, vector table address offsets, and
interrupt priorities.
Each interrupt source is allocated a different vector number and vector table address offset. Vector
table addresses are calculated from the vector numbers and vector table address offsets. In
interrupt exception handling, the interrupt exception service routine start address is fetched from
the vector table indicated by the vector table address. For details of calculation of the vector table
address, see table 6.4 in section 6, Exception Handling.
The priorities of IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be
set freely between 0 and 15 for each pin or module by setting interrupt priority registers 01, 02,
and 05 to 22 (IPR01, IPR02, and IPR05 to IPR22). However, if two or more interrupts specified
by the same IPR among IPR05 to IPR22 occur, the priorities are defined as shown in the IPR
setting unit internal priority of table 7.4, and the priorities cannot be changed. A power-on reset
assigns priority level 0 to IRQ interrupts, PINT interrupts, and on-chip peripheral module
interrupts. If the same priority level is assigned to two or more interrupt sources and interrupts
from those sources occur simultaneously, they are processed by the default priorities indicated in
table 7.4.

Operation
7.6.1
Interrupt Operation Sequence
Section 7 Interrupt Controller
The sequence of interrupt operations is described below. Figure 7.2 shows the operation flow.
1. The interrupt request sources send interrupt request signals to the interrupt controller.
2. The interrupt controller selects the highest-priority interrupt from the interrupt requests sent,
following the priority levels set in interrupt priority registers 01, 02, and 05 to 22 (IPR01,
IPR02, and IPR05 to IPR22). Lower priority interrupts are ignored*. If two of these interrupts
have the same priority level or if multiple interrupts occur within a single IPR, the interrupt
with the highest priority is selected, according to the default priority and IPR setting unit
internal priority shown in table 7.4.
3. The priority level of the interrupt selected by the interrupt controller is compared with the
interrupt level mask bits (I3 to I0) in the status register (SR) of the CPU. If the interrupt
request priority level is equal to or less than the level set in bits I3 to I0, the interrupt request is
ignored. If the interrupt request priority level is higher than the level in bits I3 to I0, the
interrupt controller accepts the interrupt and sends an interrupt request signal to the CPU.
4. The CPU detects the interrupt request sent from the interrupt controller when the CPU decodes
the instruction to be executed. Instead of executing the decoded instruction, the CPU starts
interrupt exception handling (figure 7.4).
5. The interrupt exception service routine start address is fetched from the exception handling
vector table corresponding to the accepted interrupt.
6. The status register (SR) is saved onto the stack, and the priority level of the accepted interrupt
is copied to bits I3 to I0 in SR.
7. The program counter (PC) is saved onto the stack.
8. The CPU jumps to the fetched interrupt exception service routine start address and starts
executing the program. The jump that occurs is not a delayed branch.

Section 7 Interrupt Controller
SH7262 Group, SH7264 Group
Notes: The interrupt source flag should be cleared in the interrupt handler. After clearing the
interrupt source flag, "time from occurrence of interrupt request until interrupt controller
identifies priority, compares it with mask bits in SR, and sends interrupt request signal to
CPU" shown in table 7.5 is required before the interrupt source sent to the CPU is actually
cancelled. To ensure that an interrupt request that should have been cleared is not
inadvertently accepted again, read the interrupt source flag after it has been cleared, and
then execute an RTE instruction.
* Interrupt requests that are designated as edge-sensing are held pending until the
interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing
the IRQ interrupt request register (IRQRR). For details, see section 7.4.3, IRQ
Interrupts.
Interrupts held pending due to edge-sensing are cleared by a power-on reset.

Section 7 Interrupt Controller
Interrupt Response Time
Table 7.5 lists the interrupt response time, which is the time from the occurrence of an interrupt
request until the interrupt exception handling starts and fetching of the first instruction in the
exception service routine begins. The interrupt processing operations differ in the cases when
banking is disabled, when banking is enabled without register bank overflow, and when banking is
enabled with register bank overflow. Figures 7.4 and 7.5 show examples of pipeline operation
when banking is disabled. Figures 7.6 and 7.7 show examples of pipeline operation when banking
is enabled without register bank overflow. Figures 7.8 and 7.9 show examples of pipeline
operation when banking is enabled with register bank overflow.

Bank Save and Restore Operations
Saving to Bank
Figure 7.11 shows register bank save operations. The following operations are performed when an
interrupt for which usage of register banks is allowed is accepted by the CPU:
a. Assume that the bank number bit value in the bank number register (IBNR), BN, is i before the
interrupt is generated.
b. The contents of registers R0 to R14, GBR, MACH, MACL, and PR, and the interrupt vector
table address offset (VTO) of the accepted interrupt are saved in the bank indicated by BN,
bank i.
c. The BN value is incremented by 1.

Restoration from Bank
The RESBANK (restore from register bank) instruction is used to restore data saved in a register
bank. After restoring data from the register banks with the RESBANK instruction at the end of the
interrupt exception service routine, execute the RTE instruction to return from interrupt exception
service routine.

Save and Restore Operations after Saving to All Banks
If an interrupt occurs and usage of the register banks is enabled for the interrupt accepted by the
CPU in a state where saving has been performed to all register banks, automatic saving to the
stack is performed instead of register bank saving if the BOVE bit in the bank number register
(IBNR) is cleared to 0. If the BOVE bit in IBNR is set to 1, register bank overflow exception
occurs and data is not saved to the stack.
Save and restore operations when using the stack are as follows:
(1)
Saving to Stack
1. The status register (SR) and program counter (PC) are saved to the stack during interrupt
exception handling.
2. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are saved to
the stack. The registers are saved to the stack in the order of MACL, MACH, GBR, PR, R14,
R13, …, R1, and R0.
3. The register bank overflow bit (BO) in SR is set to 1.
4. The bank number bit (BN) value in the bank number register (IBNR) remains set to the
maximum value of 15.
(2)
Restoration from Stack
When the RESBANK (restore from register bank) instruction is executed with the register bank
overflow bit (BO) in SR set to 1, the CPU operates as follows:
1. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are restored
from the stack. The registers are restored from the stack in the order of R0, R1, …, R13, R14,
PR, GBR, MACH, and MACL.
2. The bank number bit (BN) value in the bank number register (IBNR) remains set to the
maximum value of 15.

Section 7 Interrupt Controller
Register Bank Exception
There are two register bank exceptions (register bank errors): register bank overflow and register
bank underflow.
(1)
Register Bank Overflow
This exception occurs if, after data has been saved to all of the register banks, an interrupt for
which register bank use is allowed is accepted by the CPU, and the BOVE bit in the bank number
register (IBNR) is set to 1. In this case, the bank number bit (BN) value in the bank number
register (IBNR) remains set to the bank count of 15 and saving is not performed to the register
bank.
(2)
Register Bank Underflow
This exception occurs if the RESBANK (restore from register bank) instruction is executed when
no data has been saved to the register banks. In this case, the values of R0 to R14, GBR, MACH,
MACL, and PR do not change. In addition, the bank number bit (BN) value in the bank number
register (IBNR) remains set to 0.
7.8.5
Register Bank Error Exception Handling
When a register bank error occurs, register bank error exception handling starts. When this
happens, the CPU operates as follows:
1. The exception service routine start address which corresponds to the register bank error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction for a register bank overflow, and
the start address of the executed RESBANK instruction for a register bank underflow. To
prevent multiple interrupts from occurring at a register bank overflow, the interrupt priority
level that caused the register bank overflow is written to the interrupt mask level bits (I3 to I0)
of the status register (SR).
4. Program execution starts from the exception service routine start address.

7.9
Data Transfer with Interrupt Request Signals
Interrupt request signals can be used to activate the direct memory access controller and transfer
data.
Interrupt sources that are designated to activate the direct memory access controller are masked
without being input to the interrupt controller. The mask condition is as follows:
Mask condition = DME (DE0 interrupt source select 0 + DE1 interrupt source select 1
+ DE2 interrupt source select 2 + DE3 interrupt source select 3 +
DE4 interrupt source select 4 + DE5 interrupt source select 5 + DE6
interrupt source select 6 + DE7 interrupt source select 7 + DE8
interrupt source select 8 + DE9 interrupt source select 9 + DE10
interrupt source select 10 + DE11 interrupt source select 11 + DE12
interrupt source select 12 + DE13 interrupt source select 13 + DE14
interrupt source select 14 + DE15 interrupt source select 15)
Figure 7.13 shows a block diagram of interrupt control.
Here, DME is bit 0 in DMAOR of the direct memory access controller, and DEn (n = 0 to 15) is
bit 0 in CHCR_0 to CHCR_15 of the direct memory access controller. For details, see section 10,
Direct Memory Access Controller.

Handling Interrupt Request Signals as Sources for CPU Interrupt but Not Direct
Memory Access Controller Activating
1 Do not select direct memory access controller activating sources or clear the DME bit to 0. If,
direct memory access controller activating sources are selected, clear the DE bit to 0 for the
relevant channel of the direct memory access controller.
2. When interrupts occur, interrupt requests are sent to the CPU.
3. The CPU clears the interrupt source and performs the necessary processing in the interrupt
exception service routine.
7.9.2
Handling Interrupt Request Signals as Sources for Activating Direct Memory
Access Controller but Not CPU Interrupt
1. Select direct memory access controller activating sources and set both the DE and DME bits to
1. This masks CPU interrupt sources regardless of the interrupt priority register settings.
2. Activating sources are applied to the direct memory access controller when interrupts occur.
3. The direct memory access controller clears the interrupt sources when starting transfer.

Usage Note
7.10.1
Timing to Clear an Interrupt Source
SH7262 Group, SH7264 Group
The interrupt source flags should be cleared in the interrupt exception service routine. After
clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt
controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal
to CPU" shown in table 7.5 is required before the interrupt source sent to the CPU is actually
cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently
accepted again, read* the interrupt source flag after it has been cleared, and then execute an RTE
instruction.
Note: * When clearing the USB 2.0 host/function module interrupt source flag, read the flag
three times after clearing it.

Cache Structure
The cache separates data and instructions and uses a 4-way set associative system. It is composed
of four ways (banks), each of which is divided into an address section and a data section.
In each way, each of the address and data sections is divided into 128 entries. The data section of
the entry is called a line. Each line consists of 16 bytes (4 bytes 4). The data capacity per way is
2 Kbytes (16 bytes 128 entries), with a total of 8 Kbytes in the cache as a whole (4 ways).
Figure 8.1 shows the operand cache structure. The instruction cache structure is the same as the
operand cache structure except for not having the U bit.

Address Array
The V bit indicates whether the entry data is valid. When the V bit is 1, data is valid; when 0, data
is not valid.
The U bit (only for operand cache) indicates whether the entry has been written to in write-back
mode. When the U bit is 1, the entry has been written to; when 0, it has not.
The tag address holds the physical address used in the access to external memory or large-capacity
on-chip RAM. It consists of 21 bits (address bits 31 to 11) used for comparison during cache
searches. In this LSI, the addresses of the cache-enabled space are H'00000000 to H'1FFFFFFF
(see section 9, Bus State Controller), and therefore the upper three bits of the tag address are
cleared to 0.
The V and U bits are initialized to 0 by a power-on reset but not initialized by a manual reset or in
software standby mode. The tag address is not initialized by a power-on reset or manual reset or in
software standby mode.

Data Array
Holds a 16-byte instruction or data. Entries are registered in the cache in line units (16 bytes).
The data array is not initialized by a power-on reset or manual reset or in software standby mode.

Section 8 Cache
LRU
With the 4-way set associative system, up to four instructions or data with the same entry address
can be registered in the cache. When an entry is registered, LRU shows which of the four ways it
is recorded in. There are six LRU bits, controlled by hardware. A least-recently-used (LRU)
algorithm is used to select the way that has been least recently accessed.
Six LRU bits indicate the way to be replaced in case of a cache miss. The relationship between
LRU and way replacement is shown in table 8.1 when the cache lock function (only for operand
cache) is not used (concerning the case where the cache lock function is used, see section 8.2.2,
Cache Control Register 2 (CCR2)). If a bit pattern other than those listed in table 8.1 is set in the
LRU bits by software, the cache will not function correctly. When modifying the LRU bits by
software, set one of the patterns listed in table 8.1.
The LRU bits are initialized to B'000000 by a power-on reset but not initialized by a manual reset
or in software standby mode.

Section 8 Cache
8.2.2
Cache Control Register 2 (CCR2)
CCR2 is used to enable or disable the cache locking function for operand cache and is valid in
cache locking mode only. In cache locking mode, the lock enable bit (the LE bit) in CCR2 is set to
1. In non-cache-locking mode, the cache locking function is invalid.
When a cache miss occurs in cache locking mode by executing the prefetch instruction (PREF
@Rn), the line of data pointed to by Rn is loaded into the cache according to bits 9 and 8 (the
W3LOAD and W3LOCK bits) and bits 1 and 0 (the W2LOAD and W2LOCK bits) in CCR2. The
relationship between the setting of each bit and a way, to be replaced when the prefetch instruction
is executed, are listed in table 8.3. On the other hand, when the prefetch instruction is executed
and a cache hit occurs, new data is not fetched and the entry which is already enabled is held. For
example, when the prefetch instruction is executed with W3LOAD = 1 and W3LOCK = 1
specified in cache locking mode while one-line data already exists in way 0 which is specified by
Rn, a cache hit occurs and data is not fetched to way 3.
In the cache access other than the prefetch instruction in cache locking mode, ways to be replaced
by bits W3LOCK and W2LOCK are restricted. The relationship between the setting of each bit in
CCR2 and ways to be replaced are listed in table 8.4.
Programs that change the contents of CCR2 should be placed in a cache-disabled space, and a
cache-enabled space should be accessed after reading the contents of CCR2.

Operation
Operations for the operand cache are described here. Operations for the instruction cache are
similar to those for the operand cache except for the address array not having the U bit, and there
being no prefetch operation or write operation, or a write-back buffer.
8.3.1
Searching Cache
If the operand cache is enabled (OCE bit in CCR1 is 1), whenever data in a cache-enabled area is
accessed, the cache will be searched to see if the desired data is in the cache. Figure 8.2 illustrates
the method by which the cache is searched.
Entries are selected using bits 10 to 4 of the address used to access memory and the tag address of
that entry is read. At this time, the upper three bits of the tag address are always cleared to 0. Bits
31 to 11 of the address used to access memory are compared with the read tag address. The
address comparison uses all four ways. When the comparison shows a match and the selected
entry is valid (V 1), a cache hit occurs. When the comparison does not show a match or the
selected entry is not valid (V 0), a cache miss occurs. Figure 8.2 shows a hit on way 1.

Read Access
Read Hit
In a read access, data is transferred from the cache to the CPU. LRU is updated so that the hit way
is the latest.
(2)
Read Miss
An internal bus cycle starts and the entry is updated. The way replaced follows table 8.4. Entries
are updated in 16-byte units. When the desired data that caused the miss is loaded from the
external memory or the large-capacity on-chip RAM to the cache, the data is transferred to the
CPU in parallel with being loaded to the cache. When it is loaded in the cache, the V bit is set to 1,
and LRU is updated so that the replaced way becomes the latest. In operand cache, the U bit is
additionally cleared to 0. When the U bit of the entry to be replaced by updating the entry in writeback mode is 1, the cache update cycle starts after the entry is transferred to the write-back buffer.
After the cache completes its update cycle, the write-back buffer writes the entry back to the
memory. The write-back unit is 16 bytes. Cache update operation and write-back operation to the
memory are performed in wrap-around mode. When the lower four bits of the address of readmiss data are H'4, for example, cache update operation and write-back operation to the memory
are performed in the following order of the lower 4-bit value of address: H'4 H'8 H'C
H'0.

Prefetch Operation (Only for Operand Cache)
Prefetch Hit
LRU is updated so that the hit way becomes the latest. The contents in other caches are not
modified. No data is transferred to the CPU.
(2)
Prefetch Miss
No data is transferred to the CPU. The way to be replaced follows table 8.3. Other operations are
the same as those in the case of read miss.

Section 8 Cache
Write Operation (Only for Operand Cache)
Write Hit
In a write access in write-back mode, the data is written to the cache and no write cycle to the
external memory or the large-capacity on-chip RAM is issued. The U bit of the entry written is set
to 1 and LRU is updated so that the hit way becomes the latest.
In write-through mode, the data is written to the cache and a write cycle to the external memory or
the large-capacity on-chip RAM is issued. The U bit of the written entry is not updated and LRU
is updated so that the replaced way becomes the latest.
(2)
Write Miss
In write-back mode, an internal bus cycle starts when a write miss occurs, and the entry is
updated. The way to be replaced follows table 8.4. When the U bit of the entry to be replaced is 1,
the cache update cycle starts after the entry is transferred to the write-back buffer. Data is written
to the cache, the U bit is set to 1, and the V bit is set to 1. LRU is updated so that the replaced way
becomes the latest. After the cache completes its update cycle, the write-back buffer writes the
entry back to the memory. The write-back unit is 16 bytes. Cache update operation and writeback operation to the memory are performed in wrap-around mode. When the lower four bits of
the address of write-miss data are H'4, for example, cache update operation and write-back
operation to the memory are performed in the following order of the lower 4-bit value of address:
H'4 H'8 H'C H'0.
In write-through mode, no write to cache occurs in a write miss; the write is only to the external
memory or the large-capacity on-chip RAM.
8.3.5
Write-Back Buffer (Only for Operand Cache)
When the U bit of the entry to be replaced in the write-back mode is 1, it must be written back to
the external memory or the large-capacity on-chip RAM. To increase performance, the entry to be
replaced is first transferred to the write-back buffer and fetching of new entries to the cache takes
priority over writing back to the external memory. After the cache completes to fetch the new
entry, the write-back buffer writes the entry back to the external memory or the large-capacity onchip RAM. During the write-back cycles, the cache can be accessed. The write-back buffer can
hold one line of cache data (16 bytes) and its physical address. Figure 8.3 shows the configuration
of the write-back buffer.

Coherency of Cache and External Memory or Large-Capacity On-Chip RAM
Use software to ensure coherency between the cache and the external memory or the largecapacity on-chip RAM. When memory shared by this LSI and another device is mapped in the
cache-enabled space, operate the memory-mapped cache to invalidate and write back as required.
The same operation should be performed for the memory shared by the CPU and the direct
memory access controller in this LSI.

SH7262 Group, SH7264 Group
Memory-Mapped Cache
To allow software management of the cache, cache contents can be read and written by means of
MOV instructions. The instruction cache address array is mapped onto addresses H'F0000000 to
H'F07FFFFF, and the data array onto addresses H'F1000000 to H'F17FFFFF. The operand cache
address array is mapped onto addresses H'F0800000 to H'F0FFFFFF, and the data array onto
addresses H'F1800000 to H'F1FFFFFF. Only longword can be used as the access size for the
address array and data array, and instruction fetches cannot be performed.
8.4.1
Address Array
To access an address array, the 32-bit address field (for read/write accesses) and 32-bit data field
(for write accesses) must be specified.
In the address field, specify the entry address for selecting the entry, the W bit for selecting the
way, and the A bit for specifying the existence of associative operation. In the W bit, B'00 is way
0, B'01 is way 1, B'10 is way 2, and B'11 is way 3. Since the access size of the address array is
fixed at longword, specify B'00 for bits 1 and 0 of the address.
The tag address, LRU bits, U bit (only for operand cache), and V bit are specified as data. Always
specify 0 for the upper three bits (bits 31 to 29) of the tag address.
For the address and data formats, see figure 8.4.
The following three operations are possible for the address array.
(1)
Address Array Read
The tag address, LRU bits, U bit (only for operand cache), and V bit are read from the entry
address specified by the address and the entry corresponding to the way. For the read operation,
associative operation is not performed regardless of whether the associative bit (A bit) specified
by the address is 1 or 0.
(2)
Address-Array Write (Non-Associative Operation)
When the associative bit (A bit) in the address field is cleared to 0, write the tag address, LRU
bits, U bit (only for operand cache), and V bit, specified by the data field, to the entry address
specified by the address and the entry corresponding to the way. When writing to a cache line for
which the U bit = 1 and the V bit =1 in the operand cache address array, write the contents of the
cache line back to memory, then write the tag address, LRU bits, U bit, and V bit specified by the
data field. When 0 is written to the V bit, 0 must also be written to the U bit of that entry. Write-

Section 8 Cache
back operation to the memory is performed in the following order of the lower 4-bit value of
address: H'0 H'4 H'8 H'C.
(3)
Address-Array Write (Associative Operation)
When writing with the associative bit (A bit) of the address field set to 1, the addresses in the four
ways for the entry specified by the address field are compared with the tag address that is specified
by the data field. Write the U bit (only for operand cache) and the V bit specified by the data field
to the entry of the way that has a hit. However, the tag address and LRU bits remain unchanged.
When there is no way that has a hit, nothing is written and there is no operation. This function is
used to invalidate a specific entry in the cache.
When the U bit of the entry that has had a hit is 1 in the operand cache, writing back should be
performed. However, when 0 is written to the V bit, 0 must also be written to the U bit of that
entry. Write-back operation to the memory is performed in the following order of the lower 4-bit
value of address: H'0 H'4 H'8 H'C.
8.4.2
Data Array
To access a data array, the 32-bit address field (for read/write accesses) and 32-bit data field (for
write accesses) must be specified. The address field specifies information for selecting the entry to
be accessed; the data field specifies the longword data to be written to the data array.
Specify the entry address for selecting the entry, the L bit indicating the longword position within
the (16-byte) line, and the W bit for selecting the way. In the L bit, B'00 is longword 0, B'01 is
longword 1, B'10 is longword 2, and B'11 is longword 3. In the W bit, B'00 is way 0, B'01 is way
1, B'10 is way 2, and B'11 is way 3. Since the access size of the data array is fixed at longword,
specify B'00 for bits 1 and 0 of the address.
For the address and data formats, see figure 8.4.
The following two operations are possible for the data array. Information in the address array is
not modified by this operation.
(1)
Data Array Read
The data specified by the L bit in the address is read from the entry address specified by the
address and the entry corresponding to the way.

Section 8 Cache
Usage Examples
Invalidating Specific Entries
Specific cache entries can be invalidated by writing 0 to the entry's V bit in the memory mapping
cache access. When the A bit is 1, the tag address specified by the write data is compared to the
tag address within the cache selected by the entry address, and data is written to the bits V and U
specified by the write data when a match is found. If no match is found, there is no operation.
When the V bit of an entry in the address array is set to 0, the entry is written back if the entry's U
bit is 1.
An example when a write data is specified in R0 and an address is specified in R1 is shown below.
; R0=H'0110 0010; tag address(28-11)=B'0 0001 0001 0000 0000 0, U=0, V=0
; R1=H'F080 0088; operand cache address array access, entry=B'000 1000, A=1
;
MOV.L R0,@R1
(2)
Reading the Data of a Specific Entry
The data section of a specific cache entry can be read by the memory mapping cache access. The
longword indicated in the data field of the data array in figure 8.4 is read into the register.
An example when an address is specified in R0 and data is read in R1 is shown below.
; R0=H'F100 004C; instruction cache data array access, entry=B'000 0100,
; Way=0, longword address=3

Usage Notes
1. Programs that access memory-mapped cache of the operand cache should be placed in a cachedisabled space. Programs that access memory-mapped cache of the instruction cache should be
placed in a cache-disabled space, and in each of the beginning and the end of that, two or
more read accesses to on-chip peripheral modules or external address space (cache-disabled
address) should be executed.
2. Rewriting the address array contents so that two or more ways are hit simultaneously is
prohibited. Operation is not guaranteed if the address array contents are changed so that two or
more ways are hit simultaneously.
3. Registers and memory-mapped cache can be accessed only by the CPU and not by the direct
memory access controller.

Data Bus Width and Endian Specification of Each Area and Related Pin Settings
Depending on Boot Mode
The initial state of data bus, endian specification, and settings of the pins related to this module
depends on boot mode. For boot mode, refer to section 4, Boot Mode.
In boot mode 0, the state of area 0 is fixed to the state with bus width of 16 bits and big endian,
because this LSI is started up by the program stored in the ROM connected to area 0. The initial
state of areas 1 to 6 is the same as that of area 0, but the bus width and endian specification can be
changed by a program.
In this mode, settings required to read the ROM in area 0, such as settings for some of the
addresses, the data bus, and the pin functions of CS0 and RD only, are selected automatically
immediately after a power-on reset, but the initial function settings of the other pins are as general
ports. These pins cannot be used until their functions are set by a program. Do not perform other
than read access to area 0 until the pin settings are completed.
In boot modes 1 to 3, the state of areas 0 to 6 can be changed from the initial state by the program,
because in these modes the LSI is started by the program stored in the NAND flash memory or the
serial flash memory. Since pin functions related to this module are not set automatically, they need
to be set by the user. Do not access the external address space until the pin settings are completed.
Table 9.3 shows the initial state of areas 0 to 6 in boot mode 0, 2, and 3.
The sample access waveforms shown in this section include the pins such as BS, RD/WR, and
WEn. They are the waveforms when pin functions are assigned to the general I/O ports. When 8bit bus width is used, setting for pin A0 is also needed.
For details on pin function settings, see section 32, General Purpose I/O Ports.

Notes: 1. In order to connect boot ROM using address lines A21 and above in boot mode 0, pulldown processing must be provided on the board for address lines A21 and above.
2. Depending on the type of memory used, there may be limitations on the data bus width.
For details, see 9.4.2, CSn Space Bus Control Register.
3. Since the CS1 and A0 functions are assigned to the same pin, it is not possible to use
area 1 and a device with an 8-bit bus connection at the same time.
4. Since the CS4 and A22 functions are assigned to the same pin, it is not possible to use
area 4 and a device using address lines A22 and above at the same time.

Section 9 Bus State Controller
Refresh Time Constant Register (RTCOR)
RTCOR is an 8-bit register. When RTCOR matches RTCNT, the CMF bit in RTCSR is set to 1
and RTCNT is cleared to 0.
When the RFSH bit in SDCR is 1, a memory refresh request is issued by this matching signal.
This request is maintained until the refresh operation is performed. If the request is not processed
when the next matching occurs, the previous request is ignored.
When the CMIE bit in RTCSR is set to 1, an interrupt request is issued by this matching signal.
The request continues to be output until the CMF bit in RTCSR is cleared. Clearing the CMF bit
only affects the interrupt request and does not clear the refresh request. Therefore, a combination

Endian/Access Size and Data Alignment
Section 9 Bus State Controller
This LSI supports both big endian, in which the most significant byte (MSB) of data is that in the
direction of the 0th address, and little endian, in which the least significant byte (LSB) is that in
the direction of the 0th address. In the initial state after a power-on reset, all areas will be in big
endian mode. Endian mode can be changed by setting the CSnBCR register as long as the target
space is not being accessed.
Data bus width can be selected from 8 bits and 16 bits for the normal memory and SRAM with
byte selection. It is fixed to 16 bits for SDRAM. Two data bus widths (8 bits and 16 bits) are
available for the PCMCIA interface. For MPX-I/O, the data bus width is fixed to either 8 or 16
bits, or made selectable as 8 bits or 16 bits by one of the address lines.
Endian specification and data bus width varies depending on boot mode. For details, refer to
section 9.3.2, Data Bus Width and Endian Specification for Each Area Depending on Boot Mode.
Data alignment is performed in accordance with the data bus width selected for the device. This
also means that four read operations are required to read longword data from a byte-width device.
In this LSI, data alignment and conversion of data length is performed automatically between the
respective interfaces.
Tables 9.5 to 9.8 show the relationship between device data width and access unit. Note that the
correspondence between addresses and strobe signals for the 16-bit bus width depends on the
endian setting. For example, with big endian and a 16-bit bus width, WE1 corresponds to the 0th
address, which is represented by WE0 when little endian has been selected.
Since instructions are fetched with both 32- and 16-bit accesses, their alignment in the little-endian
area is difficult. Execute instructions from big-endian area.

Normal Space Interface
Basic Timing
For access to a normal space, this LSI uses strobe signal output in consideration of the fact that
mainly static RAM will be directly connected. When using SRAM with a byte-selection pin, see
section 9.5.8, SRAM Interface with Byte Selection. Figure 9.3 shows the basic timings of normal
space access. A no-wait normal access is completed in two cycles. The BS signal is asserted for
one cycle to indicate the start of a bus cycle.

Section 9 Bus State Controller
There is no access size specification when reading. The correct access start address is output in the
least significant bit of the address, but since there is no access size specification, 16 bits are always
read in case of a 16-bit device. When writing, only the WEn signal for the byte to be written is
asserted.
It is necessary to output the data that has been read using RD when a buffer is established in the
data bus. The RD/WR signal is in a read state (high output) when no access has been carried out.
Therefore, care must be taken when controlling the external data buffer with this signal, to avoid
output collision.
Figures 9.4 and 9.5 show the basic timings in continuous access to normal space. If the WM bit in
CSnWCR is cleared to 0, a Tnop cycle is inserted after the CSn space access to evaluate the
external wait (figure 9.4). If the WM bit in CSnWCR is set to 1, external waits are ignored and no
Tnop cycle is inserted (figure 9.5).

Access Wait Control
Wait cycle insertion on a normal space access can be controlled by the settings of bits WR3 to
WR0 in CSnWCR. It is possible for areas 1, 4, and 5 to insert wait cycles independently in read
access and in write access. Areas 0, 2, 3, and 6 have common access wait for read cycle and write
cycle. The specified number of Tw cycles are inserted as wait cycles in a normal space access
shown in figure 9.8.

CSn Assert Period Expansion
The number of cycles from CSn assertion to RD, WEn assertion can be specified by setting bits
SW1 and SW0 in CSnWCR. The number of cycles from RD, WEn negation to CSn negation can
be specified by setting bits HW1 and HW0. Therefore, a flexible interface to an external device
can be obtained. Figure 9.10 shows an example. A Th cycle and a Tf cycle are added before and
after an ordinary cycle, respectively. In these cycles, RD and WEn are not asserted, while other
signals are asserted. The data output is prolonged to the Tf cycle, and this prolongation is useful
for devices with slow writing operations.

Section 9 Bus State Controller
MPX-I/O Interface
Access timing for the MPX space is shown below. In the MPX space, CS5, AH, RD, and WEn
signals control the accessing. The basic access for the MPX space consists of 2 cycles of address
output followed by an access to a normal space. The bus width for the address output cycle or the
data input/output cycle is fixed to 8 bits or 16 bits. Alternatively, it can be 8 bits or 16 bits
depending on the address to be accessed.
Output of the addresses D15 to D0 or D7 to D0 is performed from cycle Ta2 to cycle Ta3.
Because cycle Ta1 has a high-impedance state, collisions of addresses and data can be avoided
without inserting idle cycles, even in continuous access cycles. Address output is increased to 3
cycles by setting the MPXW bit in CS5WCR to 1.
The RD/WR signal is output at the same time as the CS5 signal; it is high in the read cycle and
low in the write cycle.
The data cycle is the same as that in a normal space access.
The delay cycles specified by SW[1:0] are inserted between the Ta3 and T1 cycles. The delay
cycles specified by HW[1:0] are added after the T2 cycle.
Timing charts are shown in figures 9.11 to 9.13.

SDRAM Interface
SDRAM Direct Connection
The SDRAM that can be connected to this LSI is a product that has 11/12/13 bits of row address,
8/9/10 bits of column address, 4 or less banks, and uses the A10 pin for setting precharge mode in
read and write command cycles.
The control signals for direct connection of SDRAM are RAS, CAS, RD/WR, DQMU, DQML,
CKE, CS2, and CS3. All the signals other than CS2 and CS3 are common to all areas, and signals
other than CKE are valid only when CS2 or CS3 is asserted. SDRAM can be connected to up to 2
spaces. The data bus width of the area that is connected to SDRAM is 16 bits.
Burst read/single write (burst length 1) and burst read/burst write (burst length 1) are supported as
the SDRAM operating mode.
Commands for SDRAM can be specified by RAS, CAS, RD/WR, and specific address signals.
These commands supports:
NOP
Auto-refresh (REF)
Self-refresh (SELF)
All banks pre-charge (PALL)
Specified bank pre-charge (PRE)
Bank active (ACTV)
Read (READ)
Read with pre-charge (READA)
Write (WRIT)
Write with pre-charge (WRITA)
Write mode register (MRS, EMRS)
The byte to be accessed is specified by DQMU and DQML. Reading or writing is performed for a
byte whose corresponding DQMx is low. For details on the relationship between DQMx and the
byte to be accessed, see section 9.5.1, Endian/Access Size and Data Alignment.

Address Multiplexing
An address multiplexing is specified so that SDRAM can be connected without external
multiplexing circuitry according to the setting of bits BSZ[1:0] in CSnBCR and bits A2ROW[1:0],
A2COL[1:0], A3ROW[1:0], and A3COL[1:0] in SDCR. Tables 9.9 to 9.11 show the relationship
between the settings of bits BSZ[1:0], A2ROW[1:0], A2COL[1:0], A3ROW[1:0], and
A3COL[1:0] and the bits output at the address pins. Do not specify those bits in the manner other
than this table, otherwise the operation of this LSI is not guaranteed. A25 to A18 are not
multiplexed and the original values of address are always output at these pins.
When the data bus width is 16 bits (BSZ1 and BSZ0 = B'10), A0 of SDRAM specifies a word
address. Therefore, connect this A0 pin of SDRAM to the A1 pin of the LSI; the A1 pin of
SDRAM to the A2 pin of the LSI, and so on.

Burst Read
A burst read occurs in the following cases with this LSI.
Access size in reading is larger than data bus width.
16-byte transfer in cache miss.
16-byte transfer in the direct memory access controller
This LSI always accesses the SDRAM with burst length 1. For example, read access of burst
length 1 is performed consecutively 8 times to read 16-byte continuous data from the SDRAM that
is connected to a 16-bit data bus. This access is called the burst read with the burst number 8.
Table 9.12 shows the relationship between the access size and the number of bursts.

Section 9 Bus State Controller
Figures 9.15 and 9.16 show a timing chart in burst read. In burst read, an ACTV command is
output in the Tr cycle, the READ command is issued in the Tc1, Tc2, and Tc3 cycles, the READA
command is issued in the Tc4 cycle, and the read data is received at the rising edge of the external
clock (CKIO) in the Td1 to Td4 cycles. The Tap cycle is used to wait for the completion of an
auto-precharge induced by the READA command in the SDRAM. In the Tap cycle, a new
command will not be issued to the same bank. However, access to another CS space or another
bank in the same SDRAM space is enabled. The number of Tap cycles is specified by the WTRP1
and WTRP0 bits in CS3WCR.
In this LSI, wait cycles can be inserted by specifying each bit in CS3WCR to connect the SDRAM
in variable frequencies. Figure 9.16 shows an example in which wait cycles are inserted. The
number of cycles from the Tr cycle where the ACTV command is output to the Tc1 cycle where
the READ command is output can be specified using the WTRCD1 and WTRCD0 bits in
CS3WCR. If the WTRCD1 and WTRCD0 bits specify one cycles or more, a Trw cycle where the
NOP command is issued is inserted between the Tr cycle and Tc1 cycle. The number of cycles
from the Tc1 cycle where the READ command is output to the Td1 cycle where the read data is
latched can be specified for the CS2 and CS3 spaces independently, using the A2CL1 and A2CL0
bits in CS2WCR or the A3CL1 and A3CL0 bits in CS3WCR. The number of cycles from Tc1 to
Td1 corresponds to the SDRAM CAS latency. The CAS latency for the SDRAM is normally
defined as up to three cycles. However, the CAS latency in this LSI can be specified as 1 to 4
cycles. This CAS latency can be achieved by connecting a latch circuit between this LSI and the
SDRAM.
A Tde cycle is an idle cycle required to transfer the read data into this LSI and occurs once for
every burst read or every single read.

A read access ends in one cycle when data exists in a cache-disabled space and the data bus width
is larger than or equal to the access size. As the SDRAM is set to the burst read with the burst
length 1, only the required data is output. A read access that ends in one cycle is called single read.

Burst Write
A burst write occurs in the following cases in this LSI.
Access size in writing is larger than data bus width.
Write-back of the cache
16-byte transfer in the direct memory access controller
This LSI always accesses SDRAM with burst length 1. For example, write access of burst length 1
is performed continuously 8 times to write 16-byte continuous data to the SDRAM that is
connected to a 16-bit data bus. This access is called burst write with the burst number 8. The
relationship between the access size and the number of bursts is shown in table 9.12. Figure 9.18
shows a timing chart for burst writes. In burst write, an ACTV command is output in the Tr cycle,
the WRIT command is issued in the Tc1, Tc2, and Tc3 cycles, and the WRITA command is issued
to execute an auto-precharge in the Tc4 cycle. In the write cycle, the write data is output
simultaneously with the write command. After the write command with the auto-precharge is
output, the Trw1 cycle that waits for the auto-precharge initiation is followed by the Tap cycle that
waits for completion of the auto-precharge induced by the WRITA command in the SDRAM.
Between the Trwl and the Tap cycle, a new command will not be issued to the same bank.
However, access to another CS space or another bank in the same SDRAM space is enabled. The
number of Trw1 cycles is specified by the TRWL1 and TRWL0 bits in CS3WCR. The number of
Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR.

Bank Active
The SDRAM bank function can be used to support high-speed access to the same row address.
When the BACTV bit in SDCR is 1, access is performed using commands without auto-precharge
(READ or WRIT). This function is called bank-active function. This function is valid only for area
3. When area 3 is set to bank-active mode, area 2 should be set to normal space or SRAM with
byte selection. When areas 2 and 3 are both set to SDRAM, auto precharge mode must be set.
When the bank-active function is used, precharging is not performed when the access ends. When
accessing the same row address in the same bank, it is possible to issue the READ or WRIT
command immediately, without issuing an ACTV command. As SDRAM is internally divided
into several banks, it is possible to activate one row address in each bank. If the next access is to a
different row address, a PRE command is first issued to precharge the relevant bank, then when
precharging is completed, the access is performed by issuing an ACTV command followed by a
READ or WRIT command. If this is followed by an access to a different row address, the access
time will be longer because of the precharging performed after the access request is issued. The
number of cycles between issuance of the PRE command and the ACTV command is determined
by the WTRP1 and WTPR0 bits in CS3WCR.
In a write, when an auto-precharge is performed, a command cannot be issued to the same bank
for a period of Trwl + Tap cycles after issuance of the WRITA command. When bank active mode
is used, READ or WRIT commands can be issued successively if the row address is the same. The
number of cycles can thus be reduced by Trwl + Tap cycles for each write.
There is a limit on tRAS, the time for placing each bank in the active state. If there is no guarantee
that there will not be a cache hit and another row address will be accessed within the period in
which this value is maintained by program execution, it is necessary to set auto-refresh and set the
refresh cycle to no more than the maximum value of tRAS.
A burst read cycle without auto-precharge is shown in figure 9.20, a burst read cycle for the same
row address in figure 9.21, and a burst read cycle for different row addresses in figure 9.22.
Similarly, a single write cycle without auto-precharge is shown in figure 9.23, a single write cycle
for the same row address in figure 9.24, and a single write cycle for different row addresses in
figure 9.25.
In figure 9.21, a Tnop cycle in which no operation is performed is inserted before the Tc cycle that
issues the READ command. The Tnop cycle is inserted to acquire two cycles of CAS latency for
the DQMx signal that specifies the read byte in the data read from the SDRAM. If the CAS
latency is specified as two cycles or more, the Tnop cycle is not inserted because the two cycles of
latency can be acquired even if the DQMx signal is asserted after the Tc cycle.

Section 9 Bus State Controller
When bank active mode is set, if only access cycles to the respective banks in the area 3 space are
considered, as long as access cycles to the same row address continue, the operation starts with the
cycle in figure 9.20 or 9.23, followed by repetition of the cycle in figure 9.21 or 9.24. An access to
a different area during this time has no effect. If there is an access to a different row address in the
bank active state, the bus cycle in figure 9.22 or 9.25 is executed instead of that in figure 9.21 or
9.24. In bank active mode, too, all banks become inactive after a refresh cycle or after the bus is
released as the result of bus arbitration.

Refreshing
This module has a function for controlling SDRAM refreshing. Auto-refreshing can be performed
by clearing the RMODE bit to 0 and setting the RFSH bit to 1 in SDCR. A continuous refreshing
can be performed by setting the RRC2 to RRC0 bits in RTCSR. If SDRAM is not accessed for a
long period, self-refresh mode, in which the power consumption for data retention is low, can be
activated by setting both the RMODE bit and the RFSH bit to 1.

Section 9 Bus State Controller
Auto-refreshing
Refreshing is performed at intervals determined by the input clock selected by bits CKS2 to CKS0
in RTCSR, and the value set by in RTCOR. The value of bits CKS2 to CKS0 in RTCOR should
be set so as to satisfy the refresh interval stipulation for the SDRAM used. First make the settings
for RTCOR, RTCNT, and the RMODE and RFSH bits in SDCR, and then make the CKS2 to
CKS0 and RRC2 to RRC0 settings. When the clock is selected by bits CKS2 to CKS0, RTCNT
starts counting up from the value at that time. The RTCNT value is constantly compared with the
RTCOR value, and if the two values are the same, a refresh request is generated and an autorefresh is performed for the number of times specified by the RRC2 to RRC0. At the same time,
RTCNT is cleared to zero and the count-up is restarted.
Figure 9.26 shows the auto-refresh cycle timing. After starting the auto refreshing, PALL
command is issued in the Tp cycle to make all the banks to pre-charged state from active state
when some bank is being pre-charged. Then REF command is issued in the Trr cycle after
inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR. A
new command is not issued for the duration of the number of cycles specified by the WTRC1 and
WTRC0 bits in CS3WCR after the Trr cycle. The WTRC1 and WTRC0 bits must be set so as to
satisfy the SDRAM refreshing cycle time stipulation (tRC). An idle cycle is inserted between the
Tp cycle and Trr cycle when the setting value of the WTRP1 and WTRP0 bits in CS3WCR is
longer than or equal to 1 cycle.

Self-refreshing
Self-refresh mode is a kind of standby mode, in which the refresh timing and refresh addresses are
generated within the SDRAM. Self-refreshing is activated by setting both the RMODE bit and the
RFSH bit in SDCR to 1. After starting the self-refreshing, PALL command is issued in Tp cycle
after the completion of the pre-charging bank. A SELF command is then issued after inserting idle
cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WSR. SDRAM
cannot be accessed while in the self-refresh state. Self-refresh mode is cleared by clearing the
RMODE bit to 0. After self-refresh mode has been cleared, command issuance is disabled for the
number of cycles specified by the WTRC1 and WTRC0 bits in CS3WCR.
Self-refresh timing is shown in figure 9.27. Settings must be made so that self-refresh clearing and
data retention are performed correctly, and auto-refreshing is performed at the correct intervals.
When self-refreshing is activated from the state in which auto-refreshing is set, auto-refreshing is
restarted if the RFSH bit is set to 1 and the RMODE bit is cleared to 0 when self-refresh mode is
cleared. If the transition from clearing of self-refresh mode to the start of auto-refreshing takes
time, this time should be taken into consideration when setting the initial value of RTCNT.
Making the RTCNT value 1 less than the RTCOR value will enable refreshing to be started
immediately.
After self-refreshing has been set, the self-refresh state continues even if the chip standby state is
entered using the LSI standby function, and is maintained even after recovery from standby mode
due to an interrupt. Note that the necessary signals such as CKE must be driven even in standby
state by setting the HIZCNT bit in CMNCR to 1.
When the multiplication rate for the PLL circuit is changed, the CKIO output will become
unstable or will be fixed low. For details on the CKIO output, see section 5, Clock Pulse
Generator. The contents of SDRAM can be retained by placing the SDRAM in the self-refresh
state before changing the multiplication rate.
The self-refresh state is not cleared by a manual reset. In case of a power-on reset, the bus state
controller's registers are initialized, and therefore the self-refresh state is cleared.

Section 9 Bus State Controller
Relationship between Refresh Requests and Bus Cycles
If a refresh request occurs during bus cycle execution, the refresh cycle must wait for the bus cycle
to be completed. If a refresh request occurs while the bus is released by the bus arbitration
function, the refresh will not be executed until the bus mastership is acquired.
If the external bus does not return the bus for a period longer than the specified refresh interval,
refresh cannot be executed and the SDRAM contents may be lost.
If a new refresh request occurs while waiting for the previous refresh request, the previous refresh
request is deleted. To refresh correctly, a bus cycle longer than the refresh interval or the bus
mastership occupation must be prevented from occurring.
If a bus mastership is requested during self-refresh, the bus will not be released until the refresh is
completed.
(10) Low-Frequency Mode
When the SLOW bit in SDCR is set to 1, output of commands, addresses, and write data, and
fetch of read data are performed at a timing suitable for operating SDRAM at a low frequency.
Figure 9.28 shows the access timing in low-frequency mode. In this mode, commands, addresses,
and write data are output in synchronization with the falling edge of CKIO, which is half a cycle
delayed than the normal timing. Read data is fetched at the rising edge of CKIO, which is half a
cycle faster than the normal timing. This timing allows the hold time of commands, addresses,
write data, and read data to be extended.
If SDRAM is operated at a high frequency with the SLOW bit set to 1, the setup time of
commands, addresses, write data, and read data are not guaranteed. Take the operating frequency
and timing design into consideration when making the SLOW bit setting.

(11) Power-Down Mode
If the PDOWN bit in SDCR is set to 1, the SDRAM is placed in power-down mode by bringing
the CKE signal to the low level in the non-access cycle. This power-down mode can effectively
lower the power consumption in the non-access cycle. However, please note that if an access
occurs in power-down mode, a cycle of overhead occurs because a cycle is needed to assert the
CKE in order to cancel the power-down mode.

(12) Power-On Sequence
In order to use SDRAM, mode setting must first be made for SDRAM after the pose interval
specified for the SDRAM to be used after powering on. The pose interval should be obtained by a
power-on reset generating circuit or software.
To perform SDRAM initialization correctly, the registers of this module must first be set, followed
by a write to the SDRAM mode register. In SDRAM mode register setting, the address signal
value at that time is latched by a combination of the CSn, RAS, CAS, and RD/WR signals. If the
value to be set is X, the bus state controller provides for value X to be written to the SDRAM
mode register by performing a word write to address H'FFFC4000 + X for area 2 SDRAM, and to
address H'FFFC5000 + X for area 3 SDRAM. In this operation the data is ignored, but the mode
write is performed as a byte-size access. To set burst read/single write or burst read/burst write
(CAS latency 2 to 3, wrap type = sequential, and burst length 1) supported by the LSI, arbitrary
data is written in a byte-size access to the addresses shown in table 9.13. In this time 0 is output at
the external address pins of A12 or later.

Mode register setting timing is shown in figure 9.30. A PALL command (all bank pre-charge
command) is firstly issued. A REF command (auto refresh command) is then issued 8 times. An
MRS command (mode register write command) is finally issued. Idle cycles, of which number is
specified by the WTRP1 and WTRP0 bits in CS3WCR, are inserted between the PALL and the
first REF. Idle cycles, of which number is specified by the WTRC1 and WTRC0 bits in CS3WCR,
are inserted between REF and REF, and between the 8th REF and MRS. One or more idle cycles
are inserted between the MRS and a command to be issued next.
It is necessary to keep idle time of certain cycles for SDRAM before issuing PALL command after
power-on. Refer to the manual of the SDRAM for the idle time to be needed. When the pulse
width of the reset signal is longer than the idle time, mode register setting can be started
immediately after the reset, but care should be taken when the pulse width of the reset signal is
shorter than the idle time.

(13) Low-Power SDRAM
The low-power SDRAM can be accessed using the same protocol as the normal SDRAM.
The differences between the low-power SDRAM and normal SDRAM are that partial refresh
takes place that puts only a part of the SDRAM in the self-refresh state during the self-refresh
function, and that power consumption is low during refresh under user conditions such as the
operating temperature. The partial refresh is effective in systems in which the data in a work area
other than the specific area can be lost without severe repercussions. For details, please refer to the
Data Sheet for the low-power SDRAM to be used.
The low-power SDRAM supports the extension mode register in addition to the mode registers as
the normal SDRAM. This LSI supports issuing of the extension mode register write command
(EMRS).
The EMRS command is issued according to the conditions specified in table below. For example,
if data H'0YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued
to the CS3 space in the following sequence: PALL -> REF 8 -> MRS -> EMRS. In this case, the
MRS and EMRS issue addresses are H'0000XX0 and H'YYYYYYY, respectively. If data
H'1YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the
CS3 space in the following sequence: PALL -> MRS -> EMRS.

Deep power-down mode
The low-power SDRAM supports the deep power-down mode as a low-power consumption
mode. In the partial self-refresh function, self-refresh is performed on a specific area. In the
deep power-down mode, self-refresh will not be performed on any memory area. This mode is
effective in systems where all of the system memory areas are used as work areas.
If the RMODE bit in the SDCR is set to 1 while the DEEP and RFSH bits in the SDCR are set to
1, the low-power SDRAM enters the deep power-down mode. If the RMODE bit is cleared to 0,
the CKE signal is pulled high to cancel the deep power-down mode. Before executing an access
after returning from the deep power-down mode, the power-up sequence must be re-executed.

Burst ROM (Clocked Asynchronous) Interface
The burst ROM (clocked asynchronous) interface is used to access a memory with a high-speed
read function using a method of address switching called the burst mode or page mode. In a burst
ROM (clocked asynchronous) interface, basically the same access as the normal space is
performed, but the 2nd and subsequent access cycles are performed only by changing the address,
without negating the RD signal at the end of the 1st cycle. In the 2nd and subsequent access
cycles, addresses are changed at the falling edge of the CKIO.
For the 1st access cycle, the number of wait cycles specified by the W3 to W0 bits in CSnWCR is
inserted. For the 2nd and subsequent access cycles, the number of wait cycles specified by the
BW1 and BW0 bits in CSnWCR is inserted.
In the access to the burst ROM (clocked asynchronous), the BS signal is asserted only to the first
access cycle. An external wait input is valid only to the first access cycle.
In the single access or write access that does not perform the burst operation in the burst ROM
(clocked asynchronous) interface, access timing is same as a normal space.
Table 9.15 lists a relationship between bus width, access size, and the number of bursts. Figure
9.33 shows a timing chart.

SRAM Interface with Byte Selection
The SRAM interface with byte selection is a memory interface that outputs the byte selection
signal (WEn) in both read and write bus cycles. This interface has 16-bit data pins and accesses
SRAMs having upper and lower byte selection pins, such as UB and LB.
When the BAS bit in CSnWCR is cleared to 0 (initial value), the write access timing of the SRAM
interface with byte selection is the same as that for the normal space interface. While in read
access of a byte-selection SRAM interface, the byte-selection signal is output from the WEn pin,
which is different from that for the normal space interface. The basic access timing is shown in
figure 9.34. In write access, data is written to the memory according to the timing of the byteselection pin (WEn). For details, please refer to the Data Sheet for the corresponding memory.
If the BAS bit in CSnWCR is set to 1, the WEn pin and RD/WR pin timings change. Figure 9.35
shows the basic access timing. In write access, data is written to the memory according to the
timing of the write enable pin (RD/WR). The data hold timing from RD/WR negation to data write
must be acquired by setting the HW1 and HW0 bits in CSnWCR. Figure 9.36 shows the access
timing when a software wait is specified.

PCMCIA Interface
With this LSI, areas 5 and 6 can be used for the IC memory card and I/O card interface defined in
the JEIDA specifications version 4.2 (PCMCIA2.1 Rev. 2.1) by specifying bits TYPE[2:0] in
CSnBCR (n = 5 and 6) to B'101. In addition, the bits SA[1:0] in CSnWCR (n = 5 and 6) assign the
upper or lower 32 Mbytes of each area to IC memory card or I/O card interface. For example, if
the bits SA1 and SA0 in CS5WCR are set to 1 and cleared to 0, respectively, the upper 32 Mbytes
of area 5 are used for IC memory card interface and the lower 32 Mbytes are used for I/O card
interface.
When the PCMCIA interface is used, the bus size must be specified as 8 bits or 16 bits using the
bits BSZ[1:0] in CS5BCR or CS6BCR.
Figure 9.38 shows an example of connection between this LSI and a PCMCIA card. To enable hot
swapping (insertion and removal of the PCMCIA card with the system power turned on), tri-state
buffers must be connected between the bus interface of this LSI and the PCMCIA card.
In the JEIDA and PCMCIA standards, operation in big endian mode is not clearly defined.
Consequently, the provided PCMCIA interface in big endian mode is available only for this LSI.

Basic Timing for Memory Card Interface
Figure 9.39 shows the basic timing of the PCMCIA IC memory card interface. When areas 5 and 6
are specified as the PCMCIA interface, the bus is accessed with the IC memory card interface
according to the SA[1:0] bit settings in CS5WCR and CS6WCR. If the external bus frequency
(CKIO) increases, the setup times and hold times for the address pins (A25 to A0), card enable
signals (CE1A, CE2A, CE1B, CE2B), and write data (D15 to D0) to the RD and WE signals
become insufficient. To prevent this error, this LSI enables the setup times and hold times for
areas 5 and 6 to be specified independently, using CS5WCR and CS6WCR. In the PCMCIA
interface, as in the normal space interface, a software wait or hardware wait using the WAIT pin
can be inserted. Figure 9.40 shows the PCMCIA memory bus wait timing.

A port is used to generate the REG signal that switches between the common memory and
attribute memory. As shown in the example in figure 9.41, when the total memory space necessary
for the common memory and attribute memory is 32 Mbytes or less, pin A24 can be used as the
REG signal to allocate a 16-Mbyte common memory space and a 16-Mbyte attribute memory
space.

Basic Timing for I/O Card Interface
Figures 9.42 and 9.43 show the basic timing for the PCMCIA I/O card interface.
When accessing an I/O card through the PCMCIA interface, be sure to access the space as cachedisabled.
Switching between I/O card and IC memory card interfaces in the respective address spaces is
accomplished by the SA[1:0] bit settings in CS5WCR and CS6WCR.
The IOIS16 pin can be used for dynamic adjustment of the width of the I/O bus in access to an I/O
card via the PCMCIA interface when little endian mode has been selected. When the bus width of
area 5 or 6 is set to 16 bits and the IOIS16 signal is driven high during a cycle of word-unit access
to the I/O card bus, the bus width will be recognized as 8 bits and only 8 bits of data will be
accessed during the current cycle of the I/O card bus. Operation will automatically continue with
access to the remaining 8 bits of data.
The IOIS16 signal is sampled on falling edges of the CKIO in Tpci0 as well as all Tpci0w cycles
for which the TED3 to TED0 bits are set to 1.5 cycles or more, and the CE2A and CE2B signals
are updated after 1.5 cycles of the CKIO signal from the sampling point of Tpci0. Ensure that the
IOIS16 signal is defined at all sampling points and does not change along the way.
Set the TED3 to TED0 bits to satisfy the requirement of the PC card in use with regard to setup
timing from ICIORD or ICIOWR to CE1 or CE2.
The basic waveforms for dynamic bus-size adjustment are shown in figure 9.43.
Since the IOIS16 signal is not supported in big endian mode, the IOIS16 signal should be fixed to
the low level when big endian mode has been selected.

Section 9 Bus State Controller
Burst ROM (Clocked Synchronous) Interface
The burst ROM (clocked synchronous) interface is supported to access a ROM with a
synchronous burst function at high speed. The burst ROM interface accesses the burst ROM in the
same way as a normal space. This interface is valid only for area 0.
In the first access cycle, wait cycles are inserted. In this case, the number of wait cycles to be
inserted is specified by the W3 to W0 bits in CS0WCR. In the second and subsequent cycles, the
number of wait cycles to be inserted is specified by the BW1 and BW0 bits in CS0WCR.
While the burst ROM (clocked synchronous) is accessed, the BS signal is asserted only for the
first access cycle and an external wait input is also valid for the first access cycle.
Since the bus width is 16 bits, the burst length must be specified as 8. The burst ROM interface
does not support the 8-bit bus width for the burst ROM.
The burst ROM interface performs burst operations for all read access. For example, in a
longword access over a 16-bit bus, valid 16-bit data is read two times and invalid 16-bit data is
read six times. These invalid data read cycles increase the memory access time and degrade the
program execution speed and DMA transfer speed. To prevent this problem, it is recommended
using a 16-byte read by cache fill in the cache-enabled spaces or 16-byte read by the DMA. The
burst ROM interface performs write access in the same way as normal space access.

Wait between Access Cycles
As the operating frequency of LSIs becomes higher, the off-operation of the data buffer often
collides with the next data access when the read operation from devices with slow access speed is
completed. As a result of these collisions, the reliability of the device is low and malfunctions may
occur. A function that avoids data collisions by inserting idle (wait) cycles between continuous
access cycles has been newly added.
The number of wait cycles between access cycles can be set by the WM bit in CSnWCR, bits
IWW2 to IWW0, IWRWD2 to IWRWD0, IWRWS2 to IWRWS0, IWRRD2 to IWRRD0, and
IWRRS2 to IWRRS 0 in CSnBCR, and bits DMAIW2 to DMAIW0 and DMAIWA in CMNCR.
The conditions for setting the idle cycles between access cycles are shown below.

Continuous access cycles are write-read or write-write

Data output from an external device caused by DMA single address transfer is followed by
data output from another device that includes this LSI (DMAIWA = 0)
7. Data output from an external device caused by DMA single address transfer is followed by any
type of access (DMAIWA = 1)
For the specification of the number of idle cycles between access cycles described above, refer to
the description of each register.
Besides the idle cycles between access cycles specified by the registers, idle cycles must be
inserted to interface with the internal bus or to obtain the minimum pulse width for a multiplexed
pin (WEn). The following gives detailed information about the idle cycles and describes how to
estimate the number of idle cycles.
The number of idle cycles on the external bus from CSn negation to CSn or CSm assertion is
described below. Here, CSn and CSm also include CE2A and CE2B for PCMCIA.
There are eight conditions that determine the number of idle cycles on the external bus as shown
in table 9.16. The effects of these conditions are shown in figure 9.45.

No. Condition
Description
[1]
DMAIW[2:0] in
CMNCR
These bits specify the number of
0 to 12
idle cycles for DMA single address
transfer. This condition is effective
only for single address transfer and
generates idle cycles after the
access is completed.
When 0 is specified for the
number of idle cycles, the
DACK signal may be
asserted continuously. This
causes a discrepancy
between the number of
cycles detected by the device
with DACK and the direct
memory access controller
transfer count, resulting in a
malfunction.
[2]
IW***[2:0] in
CSnBCR
These bits specify the number of
0 to 12
idle cycles for access other than
single address transfer. The
number of idle cycles can be
specified independently for each
combination of the previous and
next cycles. For example, in the
case where reading CS1 space
followed by reading other CS
space, the bits IWRRD[2:0] in
CS1BCR should be set to B'100 to
specify six or more idle cycles. This
condition is effective only for access
cycles other than single address
transfer and generates idle cycles
after the access is completed.
Do not set 0 for the number
of idle cycles between
memory types which are not
allowed to be accessed
successively.
[3]
SDRAM-related These bits specify precharge
0 to 3
bits in
completion and startup wait cycles
CSnWCR
and idle cycles between commands
for SDRAM access. This condition
is effective only for SDRAM access
and generates idle cycles after the
access is completed

WM in
CSnWCR
This bit enables or disables external 0 or 1
WAIT pin input for the memory
types other than SDRAM. When
this bit is cleared to 0 (external
WAIT enabled), one idle cycle is
inserted to check the external WAIT
pin input after the access is
completed. When this bit is set to 1
(disabled), no idle cycle is
generated.
[5]
Read data
transfer cycle
One idle cycle is inserted after a
0 or 1
read access is completed. This idle
cycle is not generated for the first or
middle cycles in divided access
cycles. This is neither generated
when the HW[1:0] bits in CSnWCR
are not B'00.
One idle cycle is always
generated after a read cycle
with SDRAM or PCMCIA
interface.
[6]
Internal bus
External bus access requests from 0 or
idle cycles, etc. the CPU or the direct memory
larger
access controller and their results
are passed through the internal
bus. The external bus enters idle
state during internal bus idle cycles
or while a bus other than the
external bus is being accessed.
This condition is not effective for
divided access cycles, which are
generated by the bus state
controller when the access size is
larger than the external data bus
width.
The number of internal bus
idle cycles may not become
0 depending on the I:B
clock ratio. Tables 9.17 and
9.18 show the relationship
between the clock ratio and
the minimum number of
internal bus idle cycles.

[7]
Write data wait During write access, a write cycle is 0 or 1
cycles
executed on the external bus only
after the write data becomes ready.
This write data wait period
generates idle cycles before the
write cycle. Note that when the
previous cycle is a write cycle and
the internal bus idle cycles are
shorter than the previous write
cycle, write data can be prepared in
parallel with the previous write cycle
and therefore, no idle cycle is
generated (write buffer effect).
For write write or write
read access cycles,
successive access cycles
without idle cycles are
frequently available due to
the write buffer effect
described in the left column.
If successive access cycles
without idle cycles are not
allowed, specify the minimum
number of idle cycles
between access cycles

Idle cycles

memory types
The number of idle cycles
depends on the target
memory types. See table
9.19.
To ensure the minimum pulse width 0 to 2.5
on the signal-multiplexed pins, idle
cycles may be inserted before
access after memory types are
switched. For some memory types,
idle cycles are inserted even when
memory types are not switched.

Notes: 1. The number of idle cycles is determined by the setting of the CSnWCR.HW[1:0] bits on
the previous cycle. The number of idle cycles will be the number shown at the left when
HW[1:0] B'00, will be the number shown at the right when HW[1:0] = B'00. Also, for
CSn spaces for which the CSnWCR.HW[1:0] bits do not exist, the number of idle cycles
shown at the right will be used.
2. The number of idle cycles is determined by the setting of the CSnWCR.TEH[3:0] bits on
the previous cycle. The number of idle cycles will be the number shown at the left when
TEH[3:0] B'0000, will be the number shown at the right when TEH[3:0] = B'0000.
Figure 9.46 shows sample estimation of idle cycles between access cycles. In the actual operation,
the idle cycles may become shorter than the estimated value due to the write buffer effect or may
become longer due to internal bus idle cycles caused by stalling in the pipeline due to CPU
instruction execution or CPU register conflicts. Please consider these errors when estimating the
idle cycles.

Sample Estimation of Idle Cycles between Access Cycles
This example estimates the idle cycles for data transfer from the CS1 space to CS2 space by CPU access. Transfer is
repeated in the following order: CS1 read → CS1 read → CS2 write → CS2 write → CS1 read → ...
• Conditions
The bits for setting the idle cycles between access cycles in CS1BCR and CS2BCR are all set to 0.
In CS1WCR and CS2WCR, the WM bit is set to 1 (external WAIT pin disabled) and the HW[1:0] bits are set to 00
(CS negation is not extended).
Iφ:Bφ is set to 4:1, and no other processing is done during transfer.
For both the CS1 and CS2 spaces, normal SRAM devices are connected, the bus width is 32 bits, and access size is
also 32 bits.
The idle cycles generated under each condition are estimated for each pair of access cycles. In the following table,
R indicates a read cycle and W indicates a write cycle.

Bus Arbitration
The bus arbitration of this LSI has the bus mastership in the normal state and releases the bus
mastership after receiving a bus request from another device.
Bus mastership is transferred at the boundary of bus cycles. Namely, bus mastership is released
immediately after receiving a bus request when a bus cycle is not being performed. The release of
bus mastership is delayed until the bus cycle is complete when a bus cycle is in progress. Even
when from outside the LSI it looks like a bus cycle is not being performed, a bus cycle may be
performing internally, started by inserting wait cycles between access cycles. Therefore, it cannot
be immediately determined whether or not bus mastership has been released by looking at the CSn
signal or other bus control signals. The states that do not allow bus mastership release are shown
below.

example, between bus cycles when longword access is made to a memory with a data bus
width of 8 bits)
5. 16-byte transfer by the direct memory access controller
6. Setting the BLOCK bit in CMNCR to 1
7. During access to the external flash memory by the NAND flash memory controller
Moreover, by using DPRTY bit in CMNCR, whether the bus mastership request is received or not
can be selected during burst transfer by the direct memory access controller.
The LSI has the bus mastership until a bus request is received from another device. Upon
acknowledging the assertion (low level) of the external bus request signal BREQ, the LSI releases
the bus at the completion of the current bus cycle and asserts the BACK signal. After the LSI
acknowledges the negation (high level) of the BREQ signal that indicates the external device has
released the bus, it negates the BACK signal and resumes the bus usage.
With the SDRAM interface, all bank pre-charge commands (PALLs) are issued when active banks
exist and the bus is released after completion of a PALL command.

Section 9 Bus State Controller
The bus sequence is as follows. The address bus and data bus are placed in a high-impedance state
synchronized with the rising edge of CKIO. The bus mastership enable signal is asserted 0.5
cycles after the above timing, synchronized with the falling edge of CKIO. The bus control signals
(BS, CSn, RAS, CAS, CKE, DQMx, WEn, RD, and RD/WR) are placed in the high-impedance
state at subsequent rising edges of CKIO. These bus control signals are driven high one or more
cycles before they are placed in the high-impedance state. Bus request signals are sampled at the
falling edge of CKIO. Note that CKE, RAS, and CAS can be continued to be driven at the
previous value even in the bus-released state by setting the HIZCNT bit in CMNCR.
The sequence for reclaiming the bus mastership from an external device is described below. 1.5
cycles after the negation of BREQ is detected at the falling edge of CKIO, the bus control signals
are driven high. The bus acknowledge signal is negated at the next falling edge of the clock. The
fastest timing at which actual bus cycles can be resumed after bus control signal assertion is at the
rising edge of the CKIO where address and data signals are driven. Figure 9.47 shows the bus
arbitration timing.
When it is necessary to refresh SDRAM while releasing the bus mastership, the bus mastership
should be returned. If the bus mastership is not returned for a specified refreshing period or longer,
the contents of SDRAM cannot be guaranteed because a refreshing cannot be executed.
While releasing the bus mastership, the SLEEP instruction (to enter sleep mode, deep standby
mode, or software standby mode), as well as a manual reset, cannot be executed until the LSI
obtains the bus mastership.
The BREQ input signal is ignored in software standby mode or deep standby mode and the BACK
output signal is placed in the high impedance state. If the bus mastership request is required in this
state, the bus mastership must be released by pulling down the BACK pin to enter software
standby mode or deep standby mode.
The bus mastership release (BREQ signal for high level negation) after the bus mastership request
(BREQ signal for low level assertion) must be performed after the bus usage permission (BACK
signal for low level assertion). If the BREQ signal is negated before the BACK signal is asserted,
only one cycle of the BACK signal is asserted depending on the timing of the BREQ signal to be
negated and this may cause a bus contention between the external device and the LSI.

Reset
This module can be initialized completely only at power-on reset. At power-on reset, all signals
are negated and data output buffers are turned off regardless of the bus cycle state after the internal
reset is synchronized with the internal clock. All control registers are initialized. In software
standby, sleep, and manual reset, control registers of the bus state controller are not initialized. At
manual reset, only the current bus cycle being executed is completed. Since the RTCNT continues
counting up during manual reset signal assertion, a refresh request occurs to initiate the refresh
cycle.

Access from the Side of the LSI Internal Bus Master
There are three types of LSI internal buses: a CPU bus, internal bus, and peripheral bus. The CPU
and cache memory are connected to the CPU bus. The bus state controller and internal bus masters
other than the CPU are connected to the internal bus. Low-speed peripheral modules are connected
to the peripheral bus. Internal memories other than the cache memory are connected
bidirectionally to the CPU bus and internal bus. Access from the CPU bus to the internal bus is
enabled but access from the internal bus to the CPU bus is disabled. This gives rise to the
following problems.
On-chip bus masters such as the direct memory access controller other than the CPU can access
internal memory other than the cache memory but cannot access the cache memory. If an on-chip
bus master other than the CPU writes data to an external memory other than the cache, the
contents of the external memory may differ from that of the cache memory. To prevent this
problem, if the external memory whose contents is cached is written by an on-chip bus master
other than the CPU, the corresponding cache memory should be purged by software.
In a cache-enabled space, if the CPU initiates read access, the cache is searched. If the cache stores
data, the CPU latches the data and completes the read access. If the cache does not store data, the

SH7262 Group, SH7264 Group
Section 9 Bus State Controller
CPU performs four contiguous longword read cycles to perform cache fill operations via the
internal bus. If a cache miss occurs in byte or word operand access or at a branch to an odd word
boundary (4n + 2), the CPU performs four contiguous longword access cycles to perform a cache
fill operation on the external interface. For a cache-disabled space, the CPU performs access
according to the actual access addresses. For an instruction fetch to an even word boundary (4n),
the CPU performs longword access. For an instruction fetch to an odd word boundary (4n + 2), the
CPU performs word access.
For a read cycle of an on-chip peripheral module, the cycle is initiated through the internal bus and
peripheral bus. The read data is sent to the CPU via the peripheral bus, internal bus, and CPU bus.
In a write cycle for the cache-enabled space, the write cycle operation differs according to the
cache write methods.
In write-back mode, the cache is first searched. If data is detected at the address corresponding to
the cache, the data is then re-written to the cache. In the actual memory, data will not be re-written
until data in the corresponding address is re-written. If data is not detected at the address
corresponding to the cache, the cache is modified. In this case, data to be modified is first saved to
the internal buffer, 16-byte data including the data corresponding to the address is then read, and
data in the corresponding access of the cache is finally modified. Following these operations, a
write-back cycle for the saved 16-byte data is executed.
In write-through mode, the cache is first searched. If data is detected at the address corresponding
to the cache, the data is re-written to the cache simultaneously with the actual write via the internal
bus. If data is not detected at the address corresponding to the cache, the cache is not modified but
an actual write is performed via the internal bus.
Since the bus state controller incorporates a one-stage write buffer, it can execute an access via the
internal bus before the previous external bus cycle is completed in a write cycle. If the on-chip
module is read or written after the external low-speed memory is written, the on-chip module can
be accessed before the completion of the external low-speed memory write cycle.
In read cycles, the CPU is placed in the wait state until read operation has been completed. To
continue the process after the data write to the device has been completed, perform a dummy read
to the same address to check for completion of the write before the next process to be executed.

Section 9 Bus State Controller
SH7262 Group, SH7264 Group
The write buffer of the bus state controller functions in the same way for an access by a bus master
other than the CPU such as the direct memory access controller. Accordingly, to perform dual
address DMA transfers, the next read cycle is initiated before the previous write cycle is
completed. Note, however, that if both the DMA source and destination addresses exist in external
memory space, the next read cycle will not be initiated until the previous write cycle is completed.
Changing the registers in this module while the write buffer is operating may disrupt correct write
access. Therefore, do not change the registers in this module immediately after a write access. If
this change becomes necessary, do it after executing a dummy read of the write data.
(3)
On-Chip Peripheral Module Access
To access an on-chip module register, two or more peripheral module clock (P) cycles are
required. Care must be taken in system design.
When the CPU writes data to the internal peripheral registers, the CPU performs the succeeding
instructions without waiting for the completion of writing to registers.
For example, a case is described here in which the system is transferring to the software standby
mode for power savings. To make this transition, the SLEEP instruction must be performed after
setting the STBY bit in the STBCR1 register to 1. However a dummy read of the STBCR1 register
is required before executing the SLEEP instruction. If a dummy read is omitted, the CPU executes
the SLEEP instruction before the STBY bit is set to 1, thus the system enters sleep mode not
software standby mode. A dummy read of the STBCR1 register is indispensable to complete
writing to the STBY bit.
To reflect the change by internal peripheral registers while performing the succeeding instructions,
execute a dummy read of registers to which write instruction is given and then perform the
succeeding instructions.

External Flash Memory Access by NAND Flash Memory Controller
In this product, a part of the external data bus is used also as data bus for the NAND flash memory
controller. The use of the data bus is controlled by the NAND flash memory controller. Memory
access by the NAND flash memory controller is started after the preceding access to the external
device by this module is completed. If an access to the external device by this module occurs
during the access by the NAND flash memory controller, it must wait until the completion of the
access by the NAND flash memory controller.

Section 9 Bus State Controller
When a memory access request by the NAND flash memory controller and an external bus release
request conflict with each other, the request accepted first has higher priority. When the two
requests occur at the same time, the access by the NAND flash memory controller has higher
priority.
Auto-refresh operation and self-refresh operation are executed even during a memory access by
the NAND flash memory controller.

DMA Source Address Registers (SAR)
The DMA source address registers (SAR) are 32-bit readable/writable registers that specify the
source address of a DMA transfer. During a DMA transfer, these registers indicate the next source
address. When the data of an external device with DACK is transferred in single address mode,
SAR is ignored.
To transfer data in word (2-byte), longword (4-byte), or 16-byte unit, specify the address with 2byte, 4-byte, or16-byte address boundary respectively.

DMA Destination Address Registers (DAR)
The DMA destination address registers (DAR) are 32-bit readable/writable registers that specify
the destination address of a DMA transfer. During a DMA transfer, these registers indicate the
next destination address. When the data of an external device with DACK is transferred in single
address mode, DAR is ignored.
To transfer data in word (2-byte), longword (4-byte), or 16-byte unit, specify the address with 2byte, 4-byte, or 16-byte address boundary respectively.

Section 10 Direct Memory Access Controller
DMA Transfer Count Registers (DMATCR)
The DMA transfer count registers (DMATCR) are 32-bit readable/writable registers that specify
the number of DMA transfers. The transfer count is 1 when the setting is H'00000001, 16,777,215
when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. During a DMA
transfer, these registers indicate the remaining transfer count.
The upper eight bits of DMATCR are always read as 0, and the write value should always be 0. To
transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one.

DMA Channel Control Registers (CHCR)
The DMA channel control registers (CHCR) are 32-bit readable/writable registers that control the
DMA transfer mode.
The DO, AM, AL, DL, DS, and TL bits which specify the DREQ, DACK, and TEND external pin
functions can be read and written to in channels 0 and 1*1, but they are reserved in channels 2 to
15*2.
Notes: 1. Only channel 0 can be used in the SH7262 Group.
2. Channels 1 to 15 can be used in the SH7262 Group.

Only CHCR_0 can be used in the SH7262 Group.
Channels 1 to 15 can be used in the SH7262 Group.
Only 0 can be written to clear the flag after 1 is read.
If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal
state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be
cleared to 0 because the internal state is the same as when writing 0 after reading 1.

DMA Reload Transfer Count Registers (RDMATCR)
The DMA reload transfer count registers (RDMATCR) are 32-bit readable/writable registers.
When the SAR/DAR reload function is enabled, the RDMATCR value is written to the transfer
count register (DMATCR) at the end of the current DMA transfer. In this case, a new value for the
next DMA transfer can be preset in RDMATCR during the current DMA transfer. When the
SAR/DAR reload function is disabled, RDMATCR is ignored.
The upper eight bits of RDMATCR are always read as 0, and the write value should always be 0.
As in DMATCR, the transfer count is 1 when the setting is H'00000001, 16,777,215 when
H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. To transfer data in
16 bytes, one 16-byte transfer (128 bits) counts one.

DMA Master Enable
Enables or disables DMA transfer on all channels. If
the DME bit and DE bit in CHCR are set to 1, DMA
transfer is enabled.
However, transfer is enabled only when the TE bit in
CHCR of the transfer corresponding channel, the NMIF
bit in DMAOR, and the AE bit are all cleared to 0.
Clearing the DME bit to 0 can terminate the DMA
transfer on all channels.
0: DMA transfer is disabled on all channels
1: DMA transfer is enabled on all channels
Notes: 1. Only 0 can be written to clear the flag after 1 is read.
2. If the flag is read at the same timing it is set to 1, the read data will be 0, but the internal
state may be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be
cleared to 0 because the internal state is the same as when writing 0 after reading 1.
For details, refer to section 10.5.2, Notes on Using Flag Bits.

DMA Extension Resource Selectors 0 to 7 (DMARS0 to DMARS7)
The DMA extension resource selectors (DMARS) are 16-bit readable/writable registers that
specify the source of the DMA transfer request from peripheral modules in each channel.
DMARS0 to DMARS7 are for channels 0 and 1, 2 and 3, 4 and 5, 6 and 7, 8 and 9, 10 and 11, 12
and 13, and 14 and 15, respectively. Table 10.3 shows the specifiable combinations.
DMARS can specify the following transfer request sources (The following modules can issue onchip peripheral module requests):
Serial communication interface with FIFO: 16 sources
I2C bus interface 3: six sources
A/D converter: one source
Multi-function timer pulse unit 2: five sources
Compare match timer: two sources
USB 2.0 host/function module: two sources
NAND flash memory controller: two sources
Controller area network: two sources
Serial sound interface: five sources
Sampling rate converter: four sources
Renesas SPDIF interface: two sources
CD-ROM decoder: one source
SD host interface: two sources
Renesas serial peripheral interface: four sources
Clock synchronous serial I/O with FIFO: two sources
Motor control PWM timer: two sources
Decompression unit: two sources
Two transfer request sources for the controller area network do not need to be specified by these
registers, for they can be specified using the RS3 to RS0 bits in the DMA channel control register
(CHCR).

Peripheral Module
When MID or RID other than the values listed in table 10.3 is set, the operation of this LSI is not
guaranteed. The transfer request from DMARS is valid only when the resource select bits (RS3 to
RS0) in CHCR0 to CHCR15 have been set to B'1000. Otherwise, even if DMARS has been set,
the transfer request source is not accepted.

SH7262 Group, SH7264 Group
Operation
When there is a DMA transfer request, this module starts the transfer according to the
predetermined channel priority order; when the transfer end conditions are satisfied, it ends the
transfer. Transfers can be requested in three modes: auto request, external request, and on-chip
peripheral module request. In bus mode, the burst mode or the cycle steal mode can be selected.
10.4.1
Transfer Flow
After the DMA source address registers (SAR), DMA destination address registers (DAR), DMA
transfer count registers (DMATCR), DMA channel control registers (CHCR), DMA operation
register (DMAOR), three reload registers (RSAR, RDAR, RDMATCR) and DMA extension
resource selector (DMARS) are set for the target transfer conditions, this module transfers data
according to the following procedure:
1. Checks to see if transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when
TEMASK = 0), AE = 0, NMIF = 0).
2. When a transfer request comes and transfer is enabled, this module transfers one transfer unit
of data (depending on the settings of the TS1 and TS0 bits). For an auto request, the transfer
begins automatically when the DE bit and DME bit are set to 1. The DMATCR value will be
decremented by 1 for each transfer. The actual transfer flows vary by address mode and bus
mode.
3. When half of the specified transfer count is exceeded (when DMATCR reaches half of the
initial value), an HEI interrupt is sent to the CPU if the HIE bit in CHCR is set to 1.
4. When transfer has been completed for the specified count (when DMATCR reaches 0) while
the TEMASK bit is 0, the transfer ends normally. If the IE bit in CHCR is set to 1 at this time,
a DEI interrupt is sent to the CPU. When DMATCR reaches 0 while the TEMASK bit is 1, the
TE bit is set to 1 and then the values set in RSAR, RDAR and RDMATCR are reloaded in
SAR, DAR and DMATCR, respectively to continue transfer operation until the DMA transfer
request is cancelled.
5. When an address error in this module or an NMI interrupt is generated, the transfer is
terminated. Transfers are also terminated when the DE bit in CHCR or the DME bit in
DMAOR is cleared to 0.

10.4.2
DMA Transfer Requests
DMA transfer requests are basically generated in either the data transfer source or destination, but
they can also be generated in external devices and on-chip peripheral modules that are neither the
transfer source nor destination.
Transfers can be requested in three modes: auto request, external request, and on-chip peripheral
module request. The request mode is selected by the RS[3:0] bits in CHCR_0 to CHCR_15 and
DMARS0 to DMARS7.
(1)
Auto-Request Mode
When there is no transfer request signal from an external source, as in a memory-to-memory
transfer or a transfer between memory and an on-chip peripheral module unable to request a
transfer, the auto-request mode allows this module to automatically generate a transfer request
signal internally. When the DE bits in CHCR_0 to CHCR_15 and the DME bit in DMAOR are set
to 1, the transfer begins so long as the TE bits in CHCR_0 to CHCR_15, and the AE and NMIF
bits in DMAOR are 0.
(2)
External Request Mode
In this mode a transfer is performed at the request signals (DREQ0 and DREQ1)*1 of an external
device. Choose one of the modes shown in table 10.4 according to the application system. When
the DMA transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when TEMASK = 0),
AE = 0, NMIF = 0 for level detection; DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0 for edge

Choose to detect DREQ by either the edge or level of the signal input with the DL and DS bits in
CHCR_0 and CHCR_1*2 as shown in table 10.5. The source of the transfer request does not have
to be the data transfer source or destination. When DREQ is detected by a rising/falling edge and
DMA transfer is performed in burst mode, the transfer continues until DMATCR reaches 0 by one
DMA transfer request. In cycle steal mode, one DMA transfer is performed by one request.
Notes: 1. Only DREQ0 can be used in the SH7262 Group.
2. Only CHCR_0 can be used in the SH7262 Group.

When DREQ is accepted, the DREQ pin enters the request accept disabled state (non-sensitive
period). After issuing acknowledge DACK signal for the accepted DREQ, the DREQ pin again
enters the request accept enabled state.
When DREQ is used by level detection, there are following two cases by the timing to detect the
next DREQ after outputting DACK.
Overrun 0: Transfer is terminated after the same number of transfer has been performed as
requests.
Overrun 1: Transfer is terminated after transfers have been performed for (the number of
requests plus 1) times.
The DO bit in CHCR selects this overrun 0 or overrun 1.

On-Chip Peripheral Module Request
In this mode, the transfer is performed in response to the DMA transfer request signal from an onchip peripheral module.
Table 10.7 lists the DMA transfer request signals sent from on-chip peripheral modules to this
module.
If DMA transfer is enabled (DE = 1, DME = 1, TEMASK = 0 or 1 (TE = 0 when TEMASK = 0),
AE = 0, and NMIF = 0) in on-chip peripheral module request mode, DMA transfer is started by a
transfer request signal.
In on-chip peripheral module request mode, there are cases where transfer source or destination is
fixed. For details, see table 10.7.

Section 10 Direct Memory Access Controller
Channel Priority
When this module receives simultaneous transfer requests on two or more channels, it selects a
channel according to a predetermined priority order. Two modes (fixed mode 1 and fixed mode 2)
are selected.
In these mode, the priority levels among the channels are as follows:
Fixed mode 1:
CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 > CH8 > CH9 >
CH10 > CH11> CH12> CH13 > CH14 > CH15
Fixed mode 2:
CH0 > CH8 > CH1 > CH9 > CH2 > CH10 > CH3 > CH11> CH4 >
CH12 > CH5 > CH13 > CH6> CH14 > CH7 > CH15
These are selected by the PR1 and PR0 bits in the DMA operation register (DMAOR).
10.4.4
DMA Transfer Types
DMA transfer has two types; single address mode transfer and dual address mode transfer. They
depend on the number of bus cycles of access to the transfer source and destination. A data
transfer timing depends on the bus mode, which is the cycle steal mode or burst mode. This
module supports the transfers shown in table 10.8.

DMA transfer requires two bus cycles because data is read from the transfer source in a data read
cycle and written to the transfer destination in a data write cycle. At this time, transfer data is
temporarily stored in this module. In the transfer between external memories as shown in figure
10.3, data is read to this module from one external memory in a data read cycle, and then that data
is written to the other external memory in a data write cycle.

Auto request, external request, and on-chip peripheral module request are available for the transfer
request. DACK can be output in read cycle or write cycle in dual address mode. The AM bit in the
channel control register (CHCR) can specify whether the DACK is output in read cycle or write
cycle.

Single Address Mode
In single address mode, both the transfer source and destination are external devices, either of
them is accessed (selected) by the DACK signal, and the other device is accessed by an address. In
this mode, this module performs one DMA transfer in one bus cycle, accessing one of the external
devices by outputting the DACK transfer request acknowledge signal to it, and at the same time
outputting an address to the other device involved in the transfer. For example, in the case of
transfer between external memory and an external device with DACK shown in figure 10.5, when
the external device outputs data to the data bus, that data is written to the external memory in the
same bus cycle.

Two kinds of transfer are possible in single address mode: (1) transfer between an external device
with DACK and a memory-mapped external device, and (2) transfer between an external device
with DACK and external memory. In both cases, only the external request signal (DREQ) is used
for transfer requests.

Bus Modes
There are two bus modes; cycle steal and burst. Select the mode by the TB bits in the channel
control registers (CHCR).
(a)
Cycle Steal Mode
Normal mode
In normal mode of cycle steal, the bus mastership is given to another bus master after a onetransfer-unit (byte, word, longword, or 16-byte unit) DMA transfer. When another transfer
request occurs, the bus mastership is obtained from another bus master and a transfer is
performed for one transfer unit. When that transfer ends, the bus mastership is passed to
another bus master. This is repeated until the transfer end conditions are satisfied.
The cycle-steal normal mode can be used for any transfer section; transfer request source,
transfer source, and transfer destination.

Figure 10.7 DMA Transfer Example in Cycle-Steal Normal Mode
(Dual Address, DREQ Low Level Detection)
Intermittent Mode 16 and Intermittent Mode 64
In intermittent mode of cycle steal, this module returns the bus mastership to other bus master
whenever a unit of transfer (byte, word, longword, or 16 bytes) is completed. If the next
transfer request occurs after that, this module obtains the bus mastership from other bus master
after waiting for 16 or 64 cycles of B clock. This module then transfers data of one unit and
returns the bus mastership to other bus master. These operations are repeated until the transfer
end condition is satisfied. It is thus possible to make lower the ratio of bus occupation by
DMA transfer than the normal mode of cycle steal.
When this module obtains again the bus mastership, DMA transfer may be postponed in case
of entry updating due to cache miss.
The cycle-steal intermittent mode can be used for any transfer section; transfer request source,
transfer source, and transfer destination. The bus modes, however, must be cycle steal mode in
all channels.
Figure 10.8 shows an example of DMA transfer timing in cycle-steal intermittent mode.

Burst Mode
In burst mode, once this module obtains the bus mastership, it does not release the bus mastership
and continues to perform transfer until the transfer end condition is satisfied. In external request
mode with low-level detection of the DREQ pin, however, when the DREQ pin is driven high, the
bus mastership is passed to another bus master after the DMA transfer request that has already
been accepted ends, even if the transfer end conditions have not been satisfied.

2. Access size permitted for the on-chip peripheral module register functioning as the
transfer source or transfer destination.
3. If the transfer request is an external request, channels 0 and 1 are only available (Only
channel 0 in the SH7262 Group).
4. External requests, auto requests, and on-chip peripheral module requests are all
available. In the case of on-chip peripheral module requests, however, the compare
match timer and the multi-function timer pulse unit 2 are only available.
5. In the case of on-chip peripheral module request, only cycle steal except for the
CD-ROM decoder, the multi-function timer pulse unit 2, and the compare match timer
as the transfer request source.
6. Channel 0 is only available in the SH7262 Group.

Bus Mode and Channel Priority
In priority fixed mode (CH0 > CH1), when channel 1 is transferring data in burst mode and a
request arrives for transfer on channel 0, which has higher-priority, the data transfer on channel 0
will begin immediately. In this case, if the transfer on channel 0 is also in burst mode, the transfer
on channel 1 will only resume on completion of the transfer on channel 0.
When channel 0 is in cycle steal mode, one transfer-unit of data on this channel, which has the
higher priority, is transferred. Data is then transferred continuously to channel 1 without releasing
the bus. The bus mastership will then switch between the two in this order: channel 0, channel 1,
channel 0, channel 1, etc. That is, the CPU cycle after the data transfer in cycle steal mode is
replaced with a burst-mode transfer cycle (priority execution of burst-mode cycle). An example of
this is shown in figure 10.10.
When multiple channels are in burst mode, data transfer on the channel that has the highest
priority is given precedence. When DMA transfer is being performed on multiple channels, the
bus mastership is not released to another bus-master device until all of the competing burst-mode
transfers have been completed.

The unit of the DMA transfer is divided into multiple bus cycles when 16-byte transfer is
performed for an 8-bit or16-bit external device or when word transfer is performed for an 8-bit
external device. When a setting is made so that the DMA transfer size is divided into multiple bus
cycles and the CS signal is negated between bus cycles, note that DACK and TEND are divided
like the CS signal for data alignment as shown in figure 10.16. Figures 10.11 to 10.15 show the
cases where DACK and TEND are not divided in the DMA transfer.

Usage Notes
10.5.1
Timing of DACK and TEND Outputs
SH7262 Group, SH7264 Group
When the external memory is the MPX-I/O, the DACK output is asserted with the timing of the
data cycle. For details, see section 9.5.5, MPX-I/O Interface in section 9, Bus State Controller.
When the memory is other than the MPX-I/O, the DACK output is asserted with the same timing
as the corresponding CS signal.
The TEND output does not depend on the type of memory and is always asserted with the same
timing as the corresponding CS signal.
10.5.2
Notes on Using Flag Bits
The notes on using the following flag bits are described here.
DMA channel control register (CHCR)
HE (Half-End) and TE (Transfer End Flag) bits
DMA operation register (DMAOR)
AE (Address Error Flag) and NMIF (NMI Flag) bits
If a flag is read at the same timing it is set to 1, the read data will be 0, but the internal state may
be the same as reading 1. Therefore, if 0 is written to the flag, the flag will be cleared to 0 because
the internal state is the same as when writing 0 after reading 1.
In the case of using a flag, to prevent from unintentionally clearing the flag bit to 0, perform
read/write as follows:
(a) In the case of intended bit clear, write 0 to the flag bit after reading it as 1.
(b) In other cases, write 1 to the flag bit.
If a flag is not used, just writing 0 to the flag bit does not generate errors (in the case of intended
bit clear, write 0 to the flag bit after reading it as 1).

Timer Control Register (TCR)
The TCR registers are 8-bit readable/writable registers that control the TCNT operation for each
channel. This module has a total of five TCR registers, one each for channels 0 to 4. TCR register
settings should be conducted only when TCNT operation is stopped.

Clock Edge 0 and 1
These bits select the input clock edge. When the input
clock is counted using both edges, the input clock
period is halved (e.g. P/4 both edges = P/2 rising
edge). If phase counting mode is used on channels 1
and 2, this setting is ignored and the phase counting
mode setting has priority. Internal clock edge selection
is valid when the input clock is P/4 or slower. When
P/1, or the overflow/underflow of another channel is
selected for the input clock, although values can be
written, counter operation compiles with the initial value.

TGRC compare match is generated when in

2. Phase counting mode cannot be set for channels 0, 3, and 4.
3. Reset synchronous PWM mode, complementary PWM mode can only be set for
channel 3. When channel 3 is set to reset synchronous PWM mode or complementary
PWM mode, the channel 4 settings become ineffective and automatically conform to the
channel 3 settings. However, do not set channel 4 to reset synchronous PWM mode or
complementary PWM mode. Reset synchronous PWM mode and complementary PWM
mode cannot be set for channels 0, 1, and 2.

Timer I/O Control Register (TIOR)
The TIOR registers are 8-bit readable/writable registers that control the TGR registers. This
module has a total of eight TIOR registers, two each for channels 0, 3, and 4, one each for
channels 1 and 2.
TIOR should be set while TMDR is set in normal operation, PWM mode, or phase counting mode.
The initial output specified by TIOR is valid when the counter is stopped (the CST bit in TSTR is
cleared to 0). Note also that, in PWM mode 2, the output at the point at which the counter is
cleared to 0 is specified.
When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register
operates as a buffer register.

11.3.22 Timer Dead Time Data Register (TDDR)
TDDR is a 16-bit register, used only in complementary PWM mode that specifies the TCNT_3
and TCNT_4 counter offset values. In complementary PWM mode, when the TCNT_3 and
TCNT_4 counters are cleared and then restarted, the TDDR register value is loaded into the
TCNT_3 counter and the count operation starts.
The initial value of TDDR is H'FFFF.

TCDR is a 16-bit register used only in complementary PWM mode. Set half the PWM carrier sync
value (a value of two times TDDR + 3 or greater) as the TCDR register value. This register is
constantly compared with the TCNTS counter in complementary PWM mode, and when a match
occurs, the TCNTS counter switches direction (decrement to increment).
The initial value of TCDR is H'FFFF.

11.3.30 Bus Master Interface
The timer counters (TCNT), general registers (TGR), timer subcounter (TCNTS), timer cycle
buffer register (TCBR), timer dead time data register (TDDR), timer cycle data register (TCDR),
timer A/D converter start request control register (TADCR), timer A/D converter start request
cycle set registers (TADCOR), and timer A/D converter start request cycle set buffer registers
(TADCOBR) are 16-bit registers. A 16-bit data bus to the bus master enables 16-bit read/writes. 8bit read/write is not possible. Always access in 16-bit units.
All registers other than the above registers are 8-bit registers. These are connected to the CPU by a
16-bit data bus, so 16-bit read/writes and 8-bit read/writes are both possible.

Basic Functions
Section 11 Multi-Function Timer Pulse Unit 2
Each channel has a TCNT and TGR register. TCNT performs up-counting, and is also capable of
free-running operation, cycle counting, and external event counting.
Each TGR can be used as an input capture register or output compare register.
Always select functions for external pins of this module using the general I/O ports.

Counter Operation
When one of bits CST0 to CST4 in TSTR is set to 1, the TCNT counter for the corresponding
channel begins counting. TCNT can operate as a free-running counter, periodic counter, for
example.

Free-Running Count Operation and Periodic Count Operation:
Immediately after a reset, the TCNT counters of this module are all designated as free-running
counters. When the relevant bit in TSTR is set to 1 the corresponding TCNT counter starts upcount operation as a free-running counter. When TCNT overflows (from H'FFFF to H'0000), the
TCFV bit in TSR is set to 1. If the value of the corresponding TCIEV bit in TIER is 1 at this point,
this module requests an interrupt. After overflow, TCNT starts counting up again from H'0000.
Figure 11.5 illustrates free-running counter operation.

Figure 11.5 Free-Running Counter Operation
When compare match is selected as the TCNT clearing source, the TCNT counter for the relevant
channel performs periodic count operation. The TGR register for setting the period is designated
as an output compare register, and counter clearing by compare match is selected by means of bits
CCLR0 to CCLR2 in TCR. After the settings have been made, TCNT starts up-count operation as
a periodic counter when the corresponding bit in TSTR is set to 1. When the count value matches
the value in TGR, the TGF bit in TSR is set to 1 and TCNT is cleared to H'0000.
If the value of the corresponding TGIE bit in TIER is 1 at this point, this module requests an
interrupt. After a compare match, TCNT starts counting up again from H'0000.

Input Capture Function
The TCNT value can be transferred to TGR on detection of the TIOC pin input edge.
Rising edge, falling edge, or both edges can be selected as the detected edge. For channels 0 and 1,
it is also possible to specify another channel's counter input clock or compare match signal as the
input capture source.
Note: When another channel's counter input clock is used as the input capture input for channels
0 and 1, P/1 should not be selected as the counter input clock used for input capture
input. Input capture will not be generated if P/1 is selected.

Synchronous Operation
In synchronous operation, the values in a number of TCNT counters can be rewritten
simultaneously (synchronous presetting). Also, a number of TCNT counters can be cleared
simultaneously by making the appropriate setting in TCR (synchronous clearing).
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 4 can all be designated for synchronous operation.

Figure 11.13 shows an example of synchronous operation.
In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to
2, TGRB_0 compare match has been set as the channel 0 counter clearing source, and
synchronous clearing has been set for the channel 1 and 2 counter clearing source.
Three-phase PWM waveforms are output from pins TIOC0A, TIOC1A, and TIOC2A. At this
time, synchronous presetting, and synchronous clearing by TGRB_0 compare match, are
performed for channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM
cycle.

Buffer Operation
Buffer operation, provided for channels 0, 3, and 4, enables TGRC and TGRD to be used as buffer
registers. In channel 0, TGRF can also be used as a buffer register.
Buffer operation differs depending on whether TGR has been designated as an input capture
register or as a compare match register.
Note: TGRE_0 cannot be designated as an input capture register and can only operate as a
compare match register.
Table 11.41 shows the register combinations used in buffer operation.

When TGR is an output compare register
Figure 11.17 shows an operation example in which PWM mode 1 has been designated for channel
0, and buffer operation has been designated for TGRA and TGRC. The settings used in this
example are TCNT clearing by compare match B, 1 output at compare match A, and 0 output at
compare match B. In this example, the TTSA bit in TBTM is cleared to 0.
As buffer operation has been set, when compare match A occurs the output changes and the value
in buffer register TGRC is simultaneously transferred to timer general register TGRA. This
operation is repeated each time that compare match A occurs.

Selecting Timing for Transfer from Buffer Registers to Timer General Registers in
Buffer Operation
The timing for transfer from buffer registers to timer general registers can be selected in PWM
mode 1 or 2 for channel 0 or in PWM mode 1 for channels 3 and 4 by setting the buffer operation
transfer mode registers (TBTM_0, TBTM_3, and TBTM_4). Either compare match (initial
setting) or TCNT clearing can be selected for the transfer timing. TCNT clearing as transfer
timing is one of the following cases.
When TCNT overflows (H'FFFF to H'0000)
When H'0000 is written to TCNT during counting
When TCNT is cleared to H'0000 under the condition specified in the CCLR2 to CCLR0 bits
in TCR
Note: TBTM must be modified only while TCNT stops.
Figure 11.19 shows an operation example in which PWM mode 1 is designated for channel 0 and
buffer operation is designated for TGRA_0 and TGRC_0. The settings used in this example are
TCNT_0 clearing by compare match B, 1 output at compare match A, and 0 output at compare
match B. The TTSA bit in TBTM_0 is set to 1.

Cascaded Operation
In cascaded operation, two 16-bit counters for different channels are used together as a 32-bit
counter.
This function works by counting the channel 1 counter clock upon overflow/underflow of
TCNT_2 as set in bits TPSC0 to TPSC2 in TCR.
Underflow occurs only when the lower 16-bit TCNT is in phase-counting mode.
Table 11.42 shows the register combinations used in cascaded operation.
Note: When phase counting mode is set for channel 1, the counter clock setting is invalid and the
counters operates independently in phase counting mode.

TCNT_2
For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional
input capture input pins can be specified by the input capture control register (TICCR). The edge
detection that is the condition for input capture uses a signal representing the logical OR of the
original input pin and the added input pins. For details, see (4) Cascaded Operation Example (c).

TIOC2A rising edge for the input capture timing.
Under these conditions, the rising edge of both TIOC1A and TIOC2A is used for the TGRA_1

PWM Modes
In PWM mode, PWM waveforms are output from the output pins. The output level can be selected
as 0, 1, or toggle output in response to a compare match of each TGR.
TGR registers settings can be used to output a PWM waveform in the range of 0% to 100% duty.
Designating TGR compare match as the counter clearing source enables the period to be set in that
register. All channels can be designated for PWM mode independently. Synchronous operation is
also possible.
There are two PWM modes, as described below.
PWM mode 1
PWM output is generated from the TIOCA and TIOCC pins by pairing TGRA with TGRB and
TGRC with TGRD. The output specified by bits IOA0 to IOA3 and IOC0 to IOC3 in TIOR is
output from the TIOCA and TIOCC pins at compare matches A and C, and the output
specified by bits IOB0 to IOB3 and IOD0 to IOD3 in TIOR is output at compare matches B
and D. The initial output value is the value set in TGRA or TGRC. If the set values of paired
TGRs are identical, the output value does not change when a compare match occurs.
In PWM mode 1, a maximum 8-phase PWM output is possible.
PWM mode 2
PWM output is generated using one TGR as the cycle register and the others as duty registers.
The output specified in TIOR is performed by means of compare matches. Upon counter
clearing by a cycle register compare match, the output value of each pin is the initial value set
in TIOR. If the set values of the cycle and duty registers are identical, the output value does
not change when a compare match occurs.
In PWM mode 2, a maximum 8-phase PWM output is possible in combination use with
synchronous operation.
The correspondence between PWM output pins and registers is shown in table 11.44.

Phase Counting Mode
In phase counting mode, the phase difference between two external clock inputs is detected and
TCNT is incremented/decremented accordingly. This mode can be set for channels 1 and 2.
When phase counting mode is set, an external clock is selected as the counter input clock and
TCNT operates as an up/down-counter regardless of the setting of bits TPSC0 to TPSC2 and bits
CKEG0 and CKEG1 in TCR. However, the functions of bits CCLR0 and CCLR1 in TCR, and of
TIOR, TIER, and TGR, are valid, and input capture/compare match and interrupt functions can be
used.
This can be used for two-phase encoder pulse input.
If overflow occurs when TCNT is counting up, the TCFV flag in TSR is set; if underflow occurs
when TCNT is counting down, the TCFU flag is set.
The TCFD bit in TSR is the count direction flag. Reading the TCFD flag reveals whether TCNT is
counting up or down.

Phase Counting Mode Application Example
Figure 11.34 shows an example in which channel 1 is in phase counting mode, and channel 1 is
coupled with channel 0 to input servo motor 2-phase encoder pulses in order to detect position or
speed.
Channel 1 is set to phase counting mode 1, and the encoder pulse A-phase and B-phase are input
to TCLKA and TCLKB.
Channel 0 operates with TCNT counter clearing by TGRC_0 compare match; TGRA_0 and
TGRC_0 are used for the compare match function and are set with the speed control period and
position control period. TGRB_0 is used for input capture, with TGRB_0 and TGRD_0 operating
in buffer mode. The channel 1 counter input clock is designated as the TGRB_0 input capture
source, and the pulse widths of 2-phase encoder 4-multiplication pulses are detected.
TGRA_1 and TGRB_1 for channel 1 are designated for input capture, and channel 0 TGRA_0 and
TGRC_0 compare matches are selected as the input capture source and store the up/down-counter
values for the control periods.
This procedure enables the accurate detection of position and speed.

[2] Set the same counter clock and clock edge for channels

CKEG0 in the timer control register (TCR). Use bits
CCLR2-CCLR0 to set synchronous clearing only when
restarting by a synchronous clear from another channel
during complementary PWM mode operation.
[3] When performing brushless DC motor control, set bit BDC
in the timer gate control register (TGCR) and set the
feedback signal input source and output chopping or gate
signal direct output.
[4] Set the dead time in TCNT_3. Set TCNT_4 to H'0000.
[5] Set only when restarting by a synchronous clear from
another channel during complementary PWM mode
operation. In this case, synchronize the channel generating
the synchronous clear with channels 3 and 4 using the timer
synchro register (TSYR).
[6] Set the output PWM duty in the duty registers (TGRB_3,
TGRA_4, TGRB_4) and buffer registers (TGRD_3, TGRC_4,
TGRD_4). Set the same initial value in each corresponding
TGR.
[7] This setting is necessary only when no dead time should be
generated. Make appropriate settings in the timer dead time
enable register (TDER) so that no dead time is generated.
[8] Set the dead time in the dead time register (TDDR), 1/2 the
carrier cycle in the timer cycle data register (TCDR) and
timer cycle buffer register (TCBR), and 1/2 the carrier cycle
plus the dead time in TGRA_3 and TGRC_3. When no dead
time generation is selected, set 1 in TDDR and 1/2 the carrier
cycle + 1 in TGRA_3 and TGRC_3.
[9] Select enabling/disabling of toggle output synchronized with
the PWM cycle using bit PSYE in the timer output control
register 1 (TOCR1), and set the PWM output level with bits OLSP
and OLSN. When specifying the PWM output level by using
TOLBR as a buffer for TOCR_2, see figure 11.3.
[10] Select complementary PWM mode in timer mode register 3
(TMDR_3). Do not set in TMDR_4.
[11] Set enabling/disabling of PWM waveform output pin output in
the timer output master enable register (TOER).
[12] Set the port control register and the port I/O register.
[13] Set bits CST3 and CST4 in TSTR to 1 simultaneously to start
the count operation.

Outline of Complementary PWM Mode Operation
In complementary PWM mode, 6-phase PWM output is possible. Figure 11.39 illustrates counter
operation in complementary PWM mode, and figure 11.40 shows an example of complementary
PWM mode operation.
(a)
Counter Operation
In complementary PWM mode, three counters—TCNT_3, TCNT_4, and TCNTS—perform
up/down-count operations.
TCNT_3 is automatically initialized to the value set in TDDR when complementary PWM mode
is selected and the CST bit in TSTR is 0.
When the CST bit is set to 1, TCNT_3 counts up to the value set in TGRA_3, then switches to
down-counting when it matches TGRA_3. When the TCNT3 value matches TDDR, the counter
switches to up-counting, and the operation is repeated in this way.
TCNT_4 is initialized to H'0000.
When the CST bit is set to 1, TCNT4 counts up in synchronization with TCNT_3, and switches to
down-counting when it matches TCDR. On reaching H'0000, TCNT4 switches to up-counting,
and the operation is repeated in this way.
TCNTS is a read-only counter. It need not be initialized.
When TCNT_3 matches TCDR during TCNT_3 and TCNT_4 up/down-counting, down-counting
is started, and when TCNTS matches TCDR, the operation switches to up-counting. When
TCNTS matches TGRA_3, it is cleared to H'0000.
When TCNT_4 matches TDDR during TCNT_3 and TCNT_4 down-counting, up-counting is
started, and when TCNTS matches TDDR, the operation switches to down-counting. When
TCNTS reaches H'0000, it is set with the value in TGRA_3.
TCNTS is compared with the compare register and temporary register in which the PWM duty is
set during the count operation only.

(b)
Register Operation
In complementary PWM mode, nine registers are used, comprising compare registers, buffer
registers, and temporary registers. Figure 11.40 shows an example of complementary PWM mode
operation.
The registers which are constantly compared with the counters to perform PWM output are
TGRB_3, TGRA_4, and TGRB_4. When these registers match the counter, the value set in bits
OLSN and OLSP in the timer output control register (TOCR) is output.
The buffer registers for these compare registers are TGRD_3, TGRC_4, and TGRD_4.
Between a buffer register and compare register there is a temporary register. The temporary
registers cannot be accessed by the CPU.
Data in a compare register is changed by writing the new data to the corresponding buffer register.
The buffer registers can be read or written at any time.
The data written to a buffer register is constantly transferred to the temporary register in the Ta
interval. Data is not transferred to the temporary register in the Tb interval. Data written to a
buffer register in this interval is transferred to the temporary register at the end of the Tb interval.
The value transferred to a temporary register is transferred to the compare register when TCNTS
for which the Tb interval ends matches TGRA_3 when counting up, or H'0000 when counting
down. The timing for transfer from the temporary register to the compare register can be selected
with bits MD3 to MD0 in the timer mode register (TMDR). Figure 11.40 shows an example in
which the mode is selected in which the change is made in the trough.

Section 11 Multi-Function Timer Pulse Unit 2
In the tb interval (tb1 in figure 11.40) in which data transfer to the temporary register is not
performed, the temporary register has the same function as the compare register, and is compared
with the counter. In this interval, therefore, there are two compare match registers for one-phase
output, with the compare register containing the pre-change data, and the temporary register
containing the new data. In this interval, the three counters—TCNT_3, TCNT_4, and TCNTS—
and two registers—compare register and temporary register—are compared, and PWM output
controlled accordingly.

Initialization
In complementary PWM mode, there are six registers that must be initialized. In addition, there is
a register that specifies whether to generate dead time (it should be used only when dead time
generation should be disabled).
Before setting complementary PWM mode with bits MD3 to MD0 in the timer mode register
(TMDR), the following initial register values must be set.
TGRC_3 operates as the buffer register for TGRA_3, and should be set with 1/2 the PWM carrier
cycle + dead time Td. The timer cycle buffer register (TCBR) operates as the buffer register for
the timer cycle data register (TCDR), and should be set with 1/2 the PWM carrier cycle. Set dead
time Td in the timer dead time data register (TDDR).
When dead time is not needed, the TDER bit in the timer dead time enable register (TDER) should
be cleared to 0, TGRC_3 and TGRA_3 should be set to 1/2 the PWM carrier cycle + 1, and TDDR
should be set to 1.
Set the respective initial PWM duty values in buffer registers TGRD_3, TGRC_4, and TGRD_4.
The values set in the five buffer registers excluding TDDR are transferred simultaneously to the
corresponding compare registers when complementary PWM mode is set.
Set TCNT_4 to H'0000 before setting complementary PWM mode.

must be set to 1/2 the PWM carrier cycle + 1.

PWM Output Level Setting
In complementary PWM mode, the PWM pulse output level is set with bits OLSN and OLSP in
timer output control register 1 (TOCR1) or bits OLS1P to OLS3P and OLS1N to OLS3N in timer
output control register 2 (TOCR2).
The output level can be set for each of the three positive phases and three negative phases of 6phase output.
Complementary PWM mode should be cleared before setting or changing output levels.
(e)
Dead Time Setting
In complementary PWM mode, PWM pulses are output with a non-overlapping relationship
between the positive and negative phases. This non-overlap time is called the dead time.
The non-overlap time is set in the timer dead time data register (TDDR). The value set in TDDR is
used as the TCNT_3 counter start value, and creates non-overlap between TCNT_3 and TCNT_4.
Complementary PWM mode should be cleared before changing the contents of TDDR.
(f)
Dead Time Suppressing
Dead time generation is suppressed by clearing the TDER bit in the timer dead time enable
register (TDER) to 0. TDER can be cleared to 0 only when 0 is written to it after reading TDER =
1.
TGRA_3 and TGRC_3 should be set to 1/2 PWM carrier cycle + 1 and the timer dead time data
register (TDDR) should be set to 1.
By the above settings, PWM waveforms without dead time can be obtained. Figure 11.41 shows
an example of operation without dead time.

PWM Cycle Setting
In complementary PWM mode, the PWM pulse cycle is set in two registers—TGRA_3, in which
the TCNT_3 upper limit value is set, and TCDR, in which the TCNT_4 upper limit value is set.
The settings should be made so as to achieve the following relationship between these two
registers:
With dead time:
TGRA_3 set value = TCDR set value + TDDR set value
TCDR set value > two times TDDR + 2
Without dead time: TGRA_3 set value = TCDR set value + 1
TCDR set value > 4
The TGRA_3 and TCDR settings are made by setting the values in buffer registers TGRC_3 and
TCBR. The values set in TGRC_3 and TCBR are transferred simultaneously to TGRA_3 and
TCDR in accordance with the transfer timing selected with bits MD3 to MD0 in the timer mode
register (TMDR).
The updated PWM cycle is reflected from the next cycle when the data update is performed at the
crest, and from the current cycle when performed in the trough. Figure 11.42 illustrates the
operation when the PWM cycle is updated at the crest.

Register Data Updating
In complementary PWM mode, the buffer register is used to update the data in a compare register.
The update data can be written to the buffer register at any time. There are five PWM duty and
carrier cycle registers that have buffer registers and can be updated during operation.
There is a temporary register between each of these registers and its buffer register. When
subcounter TCNTS is not counting, if buffer register data is updated, the temporary register value
is also rewritten. Transfer is not performed from buffer registers to temporary registers when
TCNTS is counting; in this case, the value written to a buffer register is transferred after TCNTS
halts.
The temporary register value is transferred to the compare register at the data update timing set
with bits MD3 to MD0 in the timer mode register (TMDR). Figure 11.43 shows an example of
data updating in complementary PWM mode. This example shows the mode in which data
updating is performed at both the counter crest and trough.
When rewriting buffer register data, a write to TGRD_4 must be performed at the end of the
update. Data transfer from the buffer registers to the temporary registers is performed
simultaneously for all five registers after the write to TGRD_4.
A write to TGRD_4 must be performed after writing data to the registers to be updated, even when
not updating all five registers, or when updating the TGRD_4 data. In this case, the data written to
TGRD_4 should be the same as the data prior to the write operation.

Initial Output in Complementary PWM Mode
In complementary PWM mode, the initial output is determined by the setting of bits OLSN and
OLSP in timer output control register 1 (TOCR1) or bits OLS1N to OLS3N and OLS1P to OLS3P
in timer output control register 2 (TOCR2).
This initial output is the PWM pulse non-active level, and is output from when complementary
PWM mode is set with the timer mode register (TMDR) until TCNT_4 exceeds the value set in
the dead time register (TDDR). Figure 11.44 shows an example of the initial output in
complementary PWM mode.
An example of the waveform when the initial PWM duty value is smaller than the TDDR value is
shown in figure 11.45.

Section 11 Multi-Function Timer Pulse Unit 2
Complementary PWM Mode PWM Output Generation Method
In complementary PWM mode, 3-phase output is performed of PWM waveforms with a nonoverlap time between the positive and negative phases. This non-overlap time is called the dead
time.
A PWM waveform is generated by output of the output level selected in the timer output control
register in the event of a compare-match between a counter and compare register. While TCNTS
is counting, compare register and temporary register values are simultaneously compared to create
consecutive PWM pulses from 0 to 100%. The relative timing of on and off compare-match
occurrence may vary, but the compare-match that turns off each phase takes precedence to secure
the dead time and ensure that the positive phase and negative phase on times do not overlap.
Figures 11.46 to 11.48 show examples of waveform generation in complementary PWM mode.
The positive phase/negative phase off timing is generated by a compare-match with the solid-line
counter, and the on timing by a compare-match with the dotted-line counter operating with a delay
of the dead time behind the solid-line counter. In the T1 period, compare-match a that turns off the
negative phase has the highest priority, and compare-matches occurring prior to a are ignored. In
the T2 period, compare-match c that turns off the positive phase has the highest priority, and
compare-matches occurring prior to c are ignored.
In normal cases, compare-matches occur in the order a b c d (or c d a' b'), as
shown in figure 11.46.
If compare-matches deviate from the a b c d order, since the time for which the negative
phase is off is less than twice the dead time, the figure shows the positive phase is not being turned
on. If compare-matches deviate from the c d a' b' order, since the time for which the
positive phase is off is less than twice the dead time, the figure shows the negative phase is not
being turned on.
If compare-match c occurs first following compare-match a, as shown in figure 11.47, comparematch b is ignored, and the negative phase is turned off by compare-match d. This is because
turning off of the positive phase has priority due to the occurrence of compare-match c (positive
phase off timing) before compare-match b (positive phase on timing) (consequently, the waveform
does not change since the positive phase goes from off to off).
Similarly, in the example in figure 11.48, compare-match a' with the new data in the temporary
register occurs before compare-match c, but other compare-matches occurring up to c, which turns
off the positive phase, are ignored. As a result, the negative phase is not turned on.
Thus, in complementary PWM mode, compare-matches at turn-off timings take precedence, and
turn-on timing compare-matches that occur before a turn-off timing compare-match are ignored.

Complementary PWM Mode 0 and 100% Duty Output
In complementary PWM mode, 0 and 100 duty cycles can be output as required. Figures
11.49 to 11.53 show output examples.
100 duty output is performed when the compare register value is set to H'0000. The waveform in
this case has a positive phase with a 100 on-state. 0 duty output is performed when the
compare register value is set to the same value as TGRA_3. The waveform in this case has a
positive phase with a 100 off-state.
On and off compare-matches occur simultaneously, but if a turn-on compare-match and turn-off
compare-match for the same phase occur simultaneously, both compare-matches are ignored and
the waveform does not change.

Toggle Output Synchronized with PWM Cycle
In complementary PWM mode, toggle output can be performed in synchronization with the PWM
carrier cycle by setting the PSYE bit to 1 in the timer output control register (TOCR). An example
of a toggle output waveform is shown in figure 11.54.
This output is toggled by a compare-match between TCNT_3 and TGRA_3 and a compare-match
between TCNT4 and H'0000.
The output pin for this toggle output is the TIOC3A pin. The initial output is 1.

means of the timer synchronous register (TSYR), and selecting synchronous clearing with bits
CCLR2 to CCLR0 in the timer control register (TCR), it is possible to have TCNT_3, TCNT_4,
and TCNTS cleared by another channel.

Output Waveform Control at Synchronous Counter Clearing in Complementary PWM
Mode
Setting the WRE bit in TWCR to 1 suppresses initial output when synchronous counter clearing
occurs in the Tb interval at the trough in complementary PWM mode and controls abrupt change
in duty cycle at synchronous counter clearing.
Initial output suppression is applicable only when synchronous clearing occurs in the Tb interval
at the trough as indicated by (10) or (11) in figure 11.56. When synchronous clearing occurs
outside that interval, the initial value specified by the OLS bits in TOCR is output. Even in the Tb
interval at the trough, if synchronous clearing occurs in the initial value output period (indicated
by (1) in figure 11.56) immediately after the counters start operation, initial value output is not
suppressed.
When using the initial output suppression function, make sure to set compare registers TGRB_3,
TGRA_4, and TGRB_4 to a value twice or more the setting of dead time data register TDDR. If
synchronous clearing occurs with the compare registers set to a value less than twice the setting of
TDDR, the PWM output dead time may be too short (or nonexistent) or illegal active-level PWM
negative-phase output may occur during the initial output suppression interval. For details, see
section 11.7.23, Notes on Output Waveform Control During Synchronous Counter Clearing in
Complementary PWM Mode.

Example of AC Synchronous Motor (Brushless DC Motor) Drive Waveform Output
In complementary PWM mode, a brushless DC motor can easily be controlled using the timer gate
control register (TGCR). Figures 11.63 to 11.66 show examples of brushless DC motor drive
waveforms created using TGCR.
When output phase switching for a 3-phase brushless DC motor is performed by means of external
signals detected with a Hall element, etc., clear the FB bit in TGCR to 0. In this case, the external
signals indicating the polarity position are input to channel 0 timer input pins TIOC0A, TIOC0B,
and TIOC0C (set with the general I/O ports). When an edge is detected at pin TIOC0A, TIOC0B,
or TIOC0C, the output on/off state is switched automatically.
When the FB bit is 1, the output on/off state is switched when the UF, VF, or WF bit in TGCR is
cleared to 0 or set to 1.
The drive waveforms are output from the complementary PWM mode 6-phase output pins. With
this 6-phase output, in the case of on output, it is possible to use complementary PWM mode
output and perform chopping output by setting the N bit or P bit to 1. When the N bit or P bit is 0,
level output is selected.
The 6-phase output active level (on output level) can be set with the OLSN and OLSP bits in the
timer output control register (TOCR) regardless of the setting of the N and P bits.

A/D Converter Start Request Setting
In complementary PWM mode, an A/D converter start request can be issued using a TGRA_3
compare-match, TCNT_4 underflow (trough), or compare-match on a channel other than channels
3 and 4.
When start requests using a TGRA_3 compare-match are specified, A/D conversion can be started
at the crest of the TCNT_3 count.
A/D converter start requests can be set by setting the TTGE bit to 1 in the timer interrupt enable
register (TIER). To issue an A/D converter start request at a TCNT_4 underflow (trough), set the
TTGE2 bit in TIER_4 to 1.

Interrupt Skipping in Complementary PWM Mode
Interrupts TGIA_3 (at the crest) and TCIV_4 (at the trough) in channels 3 and 4 can be skipped up
to seven times by making settings in the timer interrupt skipping set register (TITCR).
Transfers from a buffer register to a temporary register or a compare register can be skipped in
coordination with interrupt skipping by making settings in the timer buffer transfer register
(TBTER). For the linkage with buffer registers, refer to description (c), Buffer Transfer Control
Linked with Interrupt Skipping, below.
A/D converter start requests generated by the A/D converter start request delaying function can
also be skipped in coordination with interrupt skipping by making settings in the timer A/D
converter request control register (TADCR). For the linkage with the A/D converter start request
delaying function, refer to section 11.4.9, A/D Converter Start Request Delaying Function.
The setting of the timer interrupt skipping setting register (TITCR) must be done while the
TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along
with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never
occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to
clear the skipping counter.

Example of Interrupt Skipping Operation Setting Procedure
Figure 11.67 shows an example of the interrupt skipping operation setting procedure. Figure 11.68
shows the periods during which interrupt skipping count can be changed.
[1] Set bits T3AEN and T4VEN in the timer interrupt
skipping set register (TITCR) to 0 to clear the
skipping counter.

Note: The setting of TITCR must be done while the
TGIA_3 and TCIV_4 interrupt requests are
disabled by the settings of TIER_3
and TIER_4 along with under the conditions in
which TGFA_3 and TCFV_4 flag settings by
compare match never occur.
Before changing the skipping count, be sure to
clear the T3AEN and T4VEN bits to 0 to clear
the skipping counter.

Buffer Transfer Control Linked with Interrupt Skipping
In complementary PWM mode, whether to transfer data from a buffer register to a temporary
register and whether to link the transfer with interrupt skipping can be specified with the BTE1
and BTE0 bits in the timer buffer transfer set register (TBTER).
Figure 11.70 shows an example of operation when buffer transfer is suppressed (BTE1 = 0 and
BTE0 = 1). While this setting is valid, data is not transferred from the buffer register to the
temporary register.
Figure 11.71 shows an example of operation when buffer transfer is linked with interrupt skipping
(BTE1 = 1 and BET0 = 0). While this setting is valid, data is not transferred from the buffer
register to the temporary register outside the buffer transfer-enabled period. Depending on the
rewrite timing from the interrupt generation to the buffer register, there are two types of the
transfer timing such as from the buffer register to the temporary register and from the temporary
register to the general register.
Note that the buffer transfer-enabled period depends on the T3AEN and T4VEN bit settings in the
timer interrupt skipping set register (TITCR). Figure 11.72 shows the relationship between the
T3AEN and T4VEN bit settings in TITCR and buffer transfer-enabled period.
Note: This function must always be used in combination with interrupt skipping.
When interrupt skipping is disabled (the T3AEN and T4VEN bits in the timer interrupt
skipping set register (TITCR) are cleared to 0 or the skipping count set bits (3ACOR and
4VCOR) in TITCR are cleared to 0), make sure that buffer transfer is not linked with
interrupt skipping (clear the BTE1 bit in the timer buffer transfer set register (TBTER) to
0). If buffer transfer is linked with interrupt skipping while interrupt skipping is disabled,
buffer transfer is never performed.

Complementary PWM Mode Output Protection Function
Complementary PWM mode output has the following protection function.
(a)
Register and counter miswrite prevention function
With the exception of the buffer registers, which can be rewritten at any time, access by the CPU
can be enabled or disabled for the mode registers, control registers, compare registers, and
counters used in complementary PWM mode by means of the RWE bit in the timer read/write
enable register (TRWER). The applicable registers are some (21 in total) of the registers in
channels 3 and 4 shown in the following:
TCR_3 and TCR_4, TMDR_3 and TMDR_4, TIORH_3 and TIORH_4, TIORL_3 and
TIORL_4, TIER_3 and TIER_4, TCNT_3 and TCNT_4, TGRA_3 and TGRA_4, TGRB_3
and TGRB_4, TOER, TOCR, TGCR, TCDR, and TDDR.
This function enables miswriting due to CPU runaway to be prevented by disabling CPU access to
the mode registers, control registers, and counters. When the applicable registers are read in the
access-disabled state, undefined values are returned. Writing to these registers is ignored.

A/D Converter Start Request Delaying Function
A/D converter start requests can be issued in channel 4 by making settings in the timer A/D
converter start request control register (TADCR), timer A/D converter start request cycle set
registers (TADCORA_4 and TADCORB_4), and timer A/D converter start request cycle set
buffer registers (TADCOBRA_4 and TADCOBRB_4).
The A/D converter start request delaying function compares TCNT_4 with TADCORA_4 or
TADCORB_4, and when their values match, the function issues a respective A/D converter start
request (TRG4AN or TRG4BN).
A/D converter start requests (TRG4AN and TRG4BN) can be skipped in coordination with
interrupt skipping by setting the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in TADCR.
Example of Procedure for Specifying A/D Converter Start Request Delaying Function
Figure 11.73 shows an example of procedure for specifying the A/D converter start request
delaying function.
[1] Set the cycle in the timer A/D converter start request cycle
buffer register (TADCOBRA_4 or TADCOBRB_4) and timer
A/D converter start request cycle register (TADCORA_4 or
TADCORB_4). (The same initial value must be specified in
the cycle buffer register and cycle register.)

[2] Use bits BF1 and BF2 in the timer A/D converter start

• Specify whether to link with interrupt skipping through bits
ITA3AE, ITA4VE, ITB3AE, and ITB4VE.
• Use bits TU4AE, DT4AE, UT4BE, and DT4BE to enable
A/D conversion start requests (TRG4AN or TRG4BN).
Notes: 1. Perform TADCR setting while TCNT_4 is stopped.
2. Do not set BF1 to 1 when complementary PWM mode
is not selected.
3. Do not set ITA3AE, ITA4VE, ITB3AE, ITB4VE,
DT4AE, or DT4BE to 1 when complementary PWM
mode is not selected.

buffer registers (TADCOBRA_4 and TADCOBRB_4). Data is transferred from the buffer
registers to the respective cycle set registers at the timing selected with the BF1 and BF0 bits
in the timer A/D converter start request control register (TADCR_4).
A/D Converter Start Request Delaying Function Linked with Interrupt Skipping
A/D converter start requests (TRG4AN and TRG4BN) can be issued in coordination with

Interrupt Sources
11.5.1
Interrupt Sources and Priorities
Section 11 Multi-Function Timer Pulse Unit 2
This module has three kinds of interrupt sources; TGR input capture/compare match, TCNT
overflow, and TCNT underflow. Each interrupt source has its own status flag and enable/disabled
bit, allowing the generation of interrupt request signals to be enabled or disabled individually.
When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the
corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The
interrupt request is cleared by clearing the status flag to 0.
Relative channel priorities can be changed by the interrupt controller, however the priority order
within a channel is fixed. For details, see section 7, Interrupt Controller.
Table 11.55 lists the interrupt sources of this module.

Input Capture/Compare Match Interrupt
An interrupt is requested if the TGIE bit in TIER is set to 1 when the TGF flag in TSR is set to 1
by the occurrence of a TGR input capture/compare match on a particular channel. The interrupt
request is cleared by clearing the TGF flag to 0. This module has eighteen input capture/compare
match interrupts, six for channel 0, four each for channels 3 and 4, and two each for channels 1
and 2. The TGFE_0 and TGFF_0 flags in channel 0 are not set by the occurrence of an input
capture.
(2)
Overflow Interrupt
An interrupt is requested if the TCIEV bit in TIER is set to 1 when the TCFV flag in TSR is set to
1 by the occurrence of TCNT overflow on a channel. The interrupt request is cleared by clearing
the TCFV flag to 0. This module has five overflow interrupts, one for each channel.

Underflow Interrupt
An interrupt is requested if the TCIEU bit in TIER is set to 1 when the TCFU flag in TSR is set to
1 by the occurrence of TCNT underflow on a channel. The interrupt request is cleared by clearing
the TCFU flag to 0. This module has two underflow interrupts, one each for channels 1 and 2.
11.5.2
Activation of Direct Memory Access Controller
The direct memory access controller can be activated by the TGRA input capture/compare match
interrupt in each channel. For details, see section 10, Direct Memory Access Controller.
In this module, a total of five TGRA input capture/compare match interrupts can be used as direct
memory access controller activation sources, one each for channels 0 to 4.
11.5.3
A/D Converter Activation
The A/D converter can be activated by one of the following three methods in this module. Table
11.56 shows the relationship between interrupt sources and A/D converter start request signals.
(1)
A/D Converter Activation by TGRA Input Capture/Compare Match or at TCNT_4
Trough in Complementary PWM Mode
The A/D converter can be activated by the occurrence of a TGRA input capture/compare match in
each channel. In addition, if complementary PWM operation is performed while the TTGE2 bit in
TIER_4 is set to 1, the A/D converter can be activated at the trough of TCNT_4 count (TCNT_4 =
H'0000).
A/D converter start request signal TRGAN is issued to the A/D converter under either one of the
following conditions.
When the TGFA flag in TSR is set to 1 by the occurrence of a TGRA input capture/compare
match on a particular channel while the TTGE bit in TIER is set to 1
When the TCNT_4 count reaches the trough (TCNT_4 = H'0000) during complementary
PWM operation while the TTGE2 bit in TIER_4 is set to 1
When either condition is satisfied, if A/D converter start signal TRGAN from this module is
selected as the trigger in the A/D converter, A/D conversion will start.

SH7262 Group, SH7264 Group
A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0
The A/D converter can be activated by generating A/D converter start request signal TRG0N
when a compare match occurs between TCNT_0 and TGRE_0 in channel 0.
When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between
TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter
start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from
this module is selected as the trigger in the A/D converter, A/D conversion will start.
(3)
A/D Converter Activation by A/D Converter Start Request Delaying Function
The A/D converter can be activated by generating A/D converter start request signal TRG4AN or
TRG4BN when the TCNT_4 count matches the TADCORA or TADCORB value if the UT4AE,
DT4AE, UT4BE, or DT4BE bit in the A/D converter start request control register (TADCR) is set
to 1. For details, refer to section 11.4.9, A/D Converter Start Request Delaying Function.
A/D conversion will start if A/D converter start signal TRG4AN from this module is selected as
the trigger in the A/D converter when TRG4AN is generated or if TRG4BN from this module is
selected as the trigger in the A/D converter when TRG4BN is generated.

Output Compare Output Timing
A compare match signal is generated in the final state in which TCNT and TGR match (the point
at which the count value matched by TCNT is updated). When a compare match signal is
generated, the output value set in TIOR is output at the output compare output pin (TIOC pin).
After a match between TCNT and TGR, the compare match signal is not generated until the
TCNT input clock is generated.
Figure 11.81 shows output compare output timing (normal mode and PWM mode) and Figure
11.82 shows output compare output timing (complementary PWM mode and reset synchronous

Usage Notes
11.7.1
Module Standby Mode Setting
Operation of this module can be disabled or enabled using the standby control register. The initial
setting is for the operation to be halted. Register access is enabled by clearing module standby
mode. For details, refer to section 33, Power-Down Modes.
11.7.2
Input Clock Restrictions
The input clock pulse width must be at least 1.5 states in the case of single-edge detection, and at
least 2.5 states in the case of both-edge detection. This module will not operate properly at
narrower pulse widths.
In phase counting mode, the phase difference and overlap between the two input clocks must be at
least 1.5 states, and the pulse width must be at least 2.5 states. Figure 11.98 shows the input clock
conditions in phase counting mode.

Caution on Period Setting
When counter clearing on compare match is set, TCNT is cleared in the final state in which it
matches the TGR value (the point at which the count value matched by TCNT is updated).
Consequently, the actual counter frequency is given by the following formula:

With timer counters TCNT1 and TCNT2 in a cascade connection, when a contention occurs
during TCNT_1 count (during a TCNT_2 overflow/underflow) in the T2 state of the TCNT_2
write cycle, the write to TCNT_2 is conducted, and the TCNT_1 count signal is disabled. At this
point, if there is match with TGRA_1 and the TCNT_1 value, a compare signal is issued.
Furthermore, when the TCNT_1 count clock is selected as the input capture source of channel 0,
TGRA_0 to D_0 carry out the input capture operation. In addition, when the compare match/input
capture is selected as the input capture source of TGRB_1, TGRB_1 carries out input capture
operation. The timing is shown in figure 11.107.
For cascade connections, be sure to synchronize settings for channels 1 and 2 when setting TCNT
clearing.

11.7.13 Counter Value during Complementary PWM Mode Stop
When counting operation is suspended with TCNT_3 and TCNT_4 in complementary PWM
mode, TCNT_3 has the timer dead time register (TDDR) value, and TCNT_4 is held at H'0000.
When restarting complementary PWM mode, counting begins automatically from the initialized
state. This explanatory diagram is shown in figure 11.108.
When counting begins in another operating mode, be sure that TCNT_3 and TCNT_4 are set to

In complementary PWM mode, conduct rewrites by buffer operation for the PWM cycle setting
register (TGRA_3), timer cycle data register (TCDR), and duty setting registers (TGRB_3,
TGRA_4, and TGRB_4).
In complementary PWM mode, channel 3 and channel 4 buffers operate in accordance with bit
settings BFA and BFB of TMDR_3. When TMDR_3's BFA bit is set to 1, TGRC_3 functions as a
buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for
TGRA_4, and TCBR functions as the TCDR's buffer register.

11.7.15 Reset Sync PWM Mode Buffer Operation and Compare Match Flag
When setting buffer operation for reset sync PWM mode, set the BFA and BFB bits of TMDR_4
to 0. The TIOC4C pin will be unable to produce its waveform output if the BFA bit of TMDR_4 is
set to 1.
In reset sync PWM mode, the channel 3 and channel 4 buffers operate in accordance with the BFA
and BFB bit settings of TMDR_3. For example, if the BFA bit of TMDR_3 is set to 1, TGRC_3
functions as the buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer
register for TGRA_4.
The TGFC bit and TGFD bit of TSR_3 and TSR_4 are not set when TGRC_3 and TGRD_3 are
operating as buffer registers.
Figure 11.109 shows an example of operations for TGR_3, TGR_4, TIOC3, and TIOC4, with
TMDR_3's BFA and BFB bits set to 1, and TMDR_4's BFA and BFB bits set to 0.

11.7.16 Overflow Flags in Reset Synchronous PWM Mode
When set to reset synchronous PWM mode, TCNT_3 and TCNT_4 start counting when the CST3
bit of TSTR is set to 1. At this point, TCNT_4's count clock source and count edge obey the
TCR_3 setting.
In reset synchronous PWM mode, with cycle register TGRA_3's set value at H'FFFF, when
specifying TGR3A compare-match for the counter clear source, TCNT_3 and TCNT_4 count up
to H'FFFF, then a compare-match occurs with TGRA_3, and TCNT_3 and TCNT_4 are both
cleared. At this point, TSR's overflow flag TCFV bit is not set.
Figure 11.110 shows a TCFV bit operation example in reset synchronous PWM mode with a set
value for cycle register TGRA_3 of H'FFFF, when a TGRA_3 compare-match has been specified
without synchronous setting for the counter clear source.

11.7.19 Cautions on Transition from Normal Operation or PWM Mode 1 to ResetSynchronized PWM Mode
When making a transition from channel 3 or 4 normal operation or PWM mode 1 to resetsynchronized PWM mode, if the counter is halted with the output pins (TIOC3B, TIOC3D,
TIOC4A, TIOC4C, TIOC4B, TIOC4D) in the high-level state, followed by the transition to resetsynchronized PWM mode and operation in that mode, the initial pin output will not be correct.
When making a transition from normal operation to reset-synchronized PWM mode, write H'11 to
registers TIORH_3, TIORL_3, TIORH_4, and TIORL_4 to initialize the output pins to low level
output, then set an initial register value of H'00 before making the mode transition.
When making a transition from PWM mode 1 to reset-synchronized PWM mode, first switch to
normal operation, then initialize the output pins to low level output and set an initial register value
of H'00 before making the transition to reset-synchronized PWM mode.

11.7.20 Output Level in Complementary PWM Mode and Reset-Synchronized PWM Mode
When channels 3 and 4 are in complementary PWM mode or reset-synchronized PWM mode, the
PWM waveform output level is set with the OLSP and OLSN bits in the timer output control
register (TOCR). In the case of complementary PWM mode or reset-synchronized PWM mode,
TIOR should be set to H'00.
11.7.21 Interrupts in Module Standby Mode
If module standby mode is entered when an interrupt has been requested, it will not be possible to
clear the CPU interrupt source or the direct memory access controller activation source. Interrupts
should therefore be disabled before entering module standby mode.
11.7.22 Simultaneous Capture of TCNT_1 and TCNT_2 in Cascade Connection
When timer counters 1 and 2 (TCNT_1 and TCNT_2) are operated as a 32-bit counter in cascade
connection, the cascade counter value cannot be captured successfully even if input-capture input
is simultaneously done to TIOC1A and TIOC2A or to TIOC1B and TIOC2B. This is because the
input timing of TIOC1A and TIOC2A or of TIOC1B and TIOC2B may not be the same when
external input-capture signals to be input into TCNT_1 and TCNT_2 are taken in synchronization
with the internal clock. For example, TCNT_1 (the counter for upper 16 bits) does not capture the
count-up value by overflow from TCNT_2 (the counter for lower 16 bits) but captures the count
value before the count-up. In this case, the values of TCNT_1 = H'FFF1 and TCNT_2 = H'0000
should be transferred to TGRA_1 and TGRA_2 or to TGRB_1 and TGRB_2, but the values of
TCNT_1 = H'FFF0 and TCNT_2 = H'0000 are erroneously transferred.

11.7.23 Notes on Output Waveform Control During Synchronous Counter Clearing in
Complementary PWM Mode
In complementary PWM mode, when output waveform control during synchronous counter
clearing is enabled (WRE in the TWCR register set to 1), the following problems may occur when
condition (1) or condition (2), below, is satisfied.
Dead time for the PWM output pins may be too short (or nonexistent).
Active-level output from the PWM negative-phase pins may occur outside the correct activelevel output interval
Condition (1): When synchronous clearing occurs in the PWM output dead time interval within
initial output suppression interval (10) (figure 11.113).
Condition (2): When synchronous clearing occurs within initial output suppression interval (10) or
(11) and TGRB_3 TDDR, TGRA_4 TDDR, or TGRB_4 TDDR is true
(figure 11.114)

Output Pin Initialization for Multi-Function Timer Pulse Unit 2
11.8.1
Operating Modes
This module has the following six operating modes. Waveform output is possible in all of these
modes.
Normal mode (channels 0 to 4)
PWM mode 1 (channels 0 to 4)
PWM mode 2 (channels 0 to 2)
Phase counting modes 1 to 4 (channels 1 and 2)
Complementary PWM mode (channels 3 and 4)
Reset-synchronized PWM mode (channels 3 and 4)
The output pin initialization method for each of these modes is described in this section.
11.8.2
Reset Start Operation
The output pins of this module (TIOC*) are initialized low by a power-on reset and in deep
standby mode. Since the pin functions are selected using the general I/O ports, when the general
I/O port is set, the pin states at that point are output to the ports. When this module output is
selected by the general I/O port immediately after a reset, the initial output level, low, is output
directly at the port. When the active level is low, the system will operate at this point, and
therefore the general I/O port setting should be made after the initialization of the output pins is
completed.
Note: Channel number and port notation are substituted for *.

11.8.3
Section 11 Multi-Function Timer Pulse Unit 2
Operation in Case of Re-Setting Due to Error during Operation, etc.
If an error occurs during operation of this module, the module output should be cut by the system.
Cutoff is performed by switching the pin output to port output with the general I/O port and
outputting the inverse of the active level. The pin initialization procedures for re-setting due to an
error during operation, etc., and the procedures for restarting in a different mode after re-setting,
are shown below.
This module has six operating modes, as stated above. There are thus 36 mode transition
combinations, but some transitions are not available with certain channel and mode combinations.
Possible mode transition combinations are shown in table 11.57.

SH7262 Group, SH7264 Group
Overview of Initialization Procedures and Mode Transitions in Case of Error
during Operation, etc.
When making a transition to a mode (Normal, PWM1, PWM2, PCM) in which the pin output
level is selected by the timer I/O control register (TIOR) setting, initialize the pins by means of
a TIOR setting.
In PWM mode 1, since a waveform is not output to the TIOC*B (TIOC *D) pin, setting TIOR
will not initialize the pins. If initialization is required, carry it out in normal mode, then switch
to PWM mode 1.
In PWM mode 2, since a waveform is not output to the cycle register pin, setting TIOR will
not initialize the pins. If initialization is required, carry it out in normal mode, then switch to
PWM mode 2.
In normal mode or PWM mode 2, if TGRC and TGRD operate as buffer registers, setting
TIOR will not initialize the buffer register pins. If initialization is required, clear buffer mode,
carry out initialization, then set buffer mode again.
In PWM mode 1, if either TGRC or TGRD operates as a buffer register, setting TIOR will not
initialize the TGRC pin. To initialize the TGRC pin, clear buffer mode, carry out initialization,
then set buffer mode again.
When making a transition to a mode (CPWM, RPWM) in which the pin output level is
selected by the timer output control register (TOCR) setting, switch to normal mode and
perform initialization with TIOR, then restore TIOR to its initial value, and temporarily disable
channel 3 and 4 output with the timer output master enable register (TOER). Then operate the
unit in accordance with the mode setting procedure (TOCR setting, TMDR setting, TOER
setting).
Note: Channel number is substituted for * indicated in this article.
Pin initialization procedures are described below for the numbered combinations in table 11.57.
The active level is assumed to be low.

Compare Match Counter (CMCNT)
CMCNT is a 16-bit register used as an up-counter. When the counter input clock is selected with
bits CKS[1:0] in CMCSR, and the STR bit in CMSTR is set to 1, CMCNT starts counting using
the selected clock. When the value in CMCNT and the value in compare match constant register
(CMCOR) match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1.
CMCNT is initialized to H'0000 by clearing any channels of the counter start bit from 1 to 0 in the
compare match timer start register (CMSTR).

Operation
12.3.1
Interval Count Operation
When an internal clock is selected with the CKS[1:0] bits in CMCSR and the STR bit in CMSTR
is set to 1, CMCNT starts incrementing using the selected clock. When the values in CMCNT and
CMCOR match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. When the
CMIE bit in CMCSR is set to 1 at this time, a compare match interrupt (CMI) is requested.
CMCNT then starts counting up again from H'0000.
Figure 12.2 shows the operation of the compare match counter.

Interrupts
12.4.1
Interrupt Sources and DMA Transfer Requests
Section 12 Compare Match Timer
This module has channels and each of them to which a different vector address is allocated has a
compare match interrupt. When both the compare match flag (CMF) and the interrupt enable bit
(CMIE) are set to 1, the corresponding interrupt request is output. When the interrupt is used to
activate a CPU interrupt, the priority of channels can be changed by the interrupt controller
settings. For details, see section 7, Interrupt Controller.
Clear the CMF bit to 0 by the user exception handling routine. If this operation is not carried out,
another interrupt will be generated. By setting the interrupt controller, the direct memory access
controller can be activated when a compare match interrupt is requested. In this case, an interrupt
is not issued to the CPU. If the setting to activate the direct memory access controller has not been
made, an interrupt request is sent to the CPU. The CMF bit is automatically cleared to 0 when data
is transferred by the direct memory access controller.
12.4.2
Timing of Compare Match Flag Setting
When CMCOR and CMCNT match, a compare match signal is generated at the last state in which
the values match (the timing when the CMCNT value is updated to H'0000) and the CMF bit in
CMCSR is set to 1. That is, after a match between CMCOR and CMCNT, the compare match
signal is not generated until the next CMCNT counter clock input. Figure 12.4 shows the timing of
CMF bit setting.

Timing of Compare Match Flag Clearing
The CMF bit in CMCSR is cleared by first, reading as 1 then writing to 0. However, in the case of

when data is transferred by the direct memory access controller.

Section 13 Watchdog Timer
Section 13 Watchdog Timer
This LSI includes the watchdog timer, which externally outputs an overflow signal (WDTOVF)
on overflow of the counter when the value of the counter has not been updated because of a
system malfunction. This module can simultaneously generate an internal reset signal for the
entire LSI.
This module is a single channel timer that counts up the clock oscillation settling period when the
system leaves software standby mode. It can also be used as a general watchdog timer or interval
timer.
13.1
Features
Can be used to ensure the clock oscillation settling time
This module is used in leaving software standby mode.
Can switch between watchdog timer mode and interval timer mode.
Outputs WDTOVF signal in watchdog timer mode
When the counter overflows in watchdog timer mode, the WDTOVF signal is output
externally. It is possible to select whether to reset the LSI internally when this happens. Either
the power-on reset or manual reset signal can be selected as the internal reset type.
Interrupt generation in interval timer mode
An interval timer interrupt is generated when the counter overflows.
Choice of eight counter input clocks
Eight clocks (P 1 to P 1/16384) that are obtained by dividing the peripheral clock can be
selected.

Watchdog Timer Counter (WTCNT)
WTCNT is an 8-bit readable/writable register that is incremented by cycles of the selected clock
signal. When an overflow occurs, it generates a watchdog timer overflow signal (WDTOVF) in
watchdog timer mode and an interrupt in interval timer mode.
Use word access to write to WTCNT, writing H'5A in the upper byte. Use byte access to read
from WTCNT.
Note: The method for writing to WTCNT differs from that for other registers to prevent
erroneous writes. See section 13.3.4, Notes on Register Access, for details.

Watchdog Timer Control/Status Register (WTCSR)
WTCSR is an 8-bit readable/writable register composed of bits to select the clock used for the
count, overflow flags, and timer enable bit.
When used to count the clock oscillation settling time for canceling software standby mode, it
retains its value after counter overflow.
Use word access to write to WTCSR, writing H'A5 in the upper byte. Use byte access to read from
WTCSR.
Note: The method for writing to WTCSR differs from that for other registers to prevent
erroneous writes. See section 13.3.4, Notes on Register Access, for details.

Notes on Register Access
The watchdog timer counter (WTCNT), watchdog timer control/status register (WTCSR), and
watchdog reset control/status register (WRCSR) are more difficult to write to than other registers.
The procedures for reading or writing to these registers are given below.
(1)
Writing to WTCNT and WTCSR
These registers must be written by a word transfer instruction. They cannot be written by a byte or
longword transfer instruction.
When writing to WTCNT, set the upper byte to H'5A and transfer the lower byte as the write data,
as shown in figure 13.2. When writing to WTCSR, set the upper byte to H'A5 and transfer the
lower byte as the write data. This transfer procedure writes the lower byte data to WTCNT or
WTCSR.

Section 13 Watchdog Timer
Writing to WRCSR
WRCSR must be written by a word access to address H'FFFE0004. It cannot be written by byte
transfer or longword transfer instructions.
Procedures for writing 0 to WOVF (bit 7) and for writing to RSTE (bit 6) and RSTS (bit 5) are
different, as shown in figure 13.3.
To write 0 to the WOVF bit, the write data must be H'A5 in the upper byte and H'00 in the lower
byte. This clears the WOVF bit to 0. The RSTE and RSTS bits are not affected. To write to the
RSTE and RSTS bits, the upper byte must be H'5A and the lower byte must be the write data. The
values of bits 6 and 5 of the lower byte are transferred to the RSTE and RSTS bits, respectively.
The WOVF bit is not affected.

Reading from WTCNT, WTCSR, and WRCSR
WTCNT, WTCSR, and WRCSR are read in a method similar to other registers. WTCSR is
allocated to address H'FFFE0000, WTCNT to address H'FFFE0002, and WRCSR to address
H'FFFE0004. Byte transfer instructions must be used for reading from these registers.

Usage
13.4.1
Canceling Software Standby Mode
SH7262 Group, SH7264 Group
This module can be used to cancel software standby mode with an interrupt such as an NMI
interrupt. The procedure is described below. (This module does not operate when resets are used
for canceling, so keep the RES or MRES pin low until clock oscillation settles.)
1. Before making a transition to software standby mode, always clear the TME bit in WTCSR
to 0. When the TME bit is 1, an erroneous reset or interval timer interrupt may be generated
when the count overflows.
2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the
counter in WTCNT. These values should ensure that the time till count overflow is longer than
the clock oscillation settling time.
3. After setting the STBY and DEEP bits of the standby control register 1 (STBCR1: see section
33, Power-Down Modes) to 1 and 0 respectively, the execution of a SLEEP instruction puts
the system in software standby mode and clock operation then stops.
4. This module starts counting by detecting the edge change of the NMI signal.
5. When the module count overflows, the clock pulse generator starts supplying the clock and
this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens.
13.4.2
Using Watchdog Timer Mode
1. Set the WT/IT bit in WTCSR to 1, the type of count clock in the CKS[2:0] bits in WTCSR,
whether this LSI is to be reset internally or not in the RSTE bit in WRCSR, the reset type if it
is generated in the RSTS bit in WRCSR, and the initial value of the counter in WTCNT.
2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode.
3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent
the counter from overflowing.
4. When the counter overflows, this module sets the WOVF flag in WRCSR to 1, and the
WDTOVF signal is output externally (figure 13.4). The WDTOVF signal can be used to reset
the system. The WDTOVF signal is output for 64 P clock cycles.
5. If the RSTE bit in WRCSR is set to 1, a signal to reset the inside of this LSI can be generated
simultaneously with the WDTOVF signal. Either power-on reset or manual reset can be
selected for this interrupt by the RSTS bit in WRCSR. The internal reset signal is output for
128 P clock cycles.
6. When an overflow reset of this module is generated simultaneously with a reset input on the
RES pin, the RES pin reset takes priority, and the WOVF bit in WRCSR is cleared to 0.

13.4.3
Using Interval Timer Mode
When operating in interval timer mode, interval timer interrupts are generated at every overflow of
the counter. This enables interrupts to be generated at set periods.
1. Clear the WT/IT bit in WTCSR to 0, set the type of count clock in the CKS[2:0] bits in
WTCSR, and set the initial value of the counter in WTCNT.
2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode.
3. When the counter overflows, this module sets the IOVF bit in WTCSR to 1 and an interval
timer interrupt request is sent to the interrupt controller. The counter then resumes counting.

Section 13 Watchdog Timer
Usage Notes
Pay attention to the following points when using this module in either the interval timer or
watchdog timer mode.
13.5.1
Timer Variation
After timer operation has started, the period from the power-on reset point to the first count up
timing of WTCNT varies depending on the time period that is set by the TME bit of WTCSR. The
shortest such time period is thus one cycle of the peripheral clock, P, while the longest is the
result of frequency division according to the value in the CKS[2:0] bits. The timing of subsequent
incrementation is in accord with the selected frequency division ratio. Accordingly, this time
difference is referred to as timer variation.
This also applies to the timing of the first incrementation after WTCNT has been written to during
timer operation.
13.5.2
Prohibition against Setting H'FF to WTCNT
When the value in WTCNT reaches H'FF, this module assumes that an overflow has occurred.
Accordingly, when H'FF is set in WTCNT, an interval timer interrupt or reset will occur
immediately, regardless of the current clock selection by the CKS[2:0] bits.
13.5.3
Interval Timer Overflow Flag
When the value in WTCNT is H'FF, the IOVF flag in WTCSR cannot be cleared.
Only clear the IOVF flag when the value in WTCNT has either become H'00 or been changed to a
value other than H'FF.

13.5.4
System Reset by WDTOVF Signal
If the WDTOVF signal is input to the RES pin of this LSI, this LSI cannot be initialized correctly.
Avoid input of the WDTOVF signal to the RES pin of this LSI through glue logic circuits. To
reset the entire system with the WDTOVF signal, use the circuit shown in figure 13.6.

13.5.5
Manual Reset in Watchdog Timer Mode
When a manual reset occurs in watchdog timer mode, the bus cycle is continued. If a manual reset
occurs while the bus is released or during burst transfer by the direct memory access controller,
manual reset exception handling will be pended until the CPU acquires the bus mastership.
13.5.6
Internal Reset in Watchdog Timer Mode
When an internal reset is generated by an overflow of the watchdog timer counter (WTCNT) in
watchdog timer mode, the watchdog reset control/status register (WRCSR) is not initialized and
the WOVF bit is set to 1. When the value of the WOVF bit is 1, no internal reset is generated
when a WTCNT overflow occurs.

64-Hz Counter (R64CNT)
R64CNT indicates the state of the divider circuit between 64 Hz and 1 Hz.
Reading this register, when carry from 128-Hz divider stage is generated, sets the CF bit in the
control register 1 (RCR1) to 1 so that the carrying and reading 64 Hz counter are performed at the
same time is indicated. In this case, the R64CNT should be read again after writing 0 to the CF bit
in RCR1 since the read value is not valid.
After the RESET bit or ADJ bit in the control register 2 (RCR2) is set to 1, the divider circuit is
initialized and R64CNT is initialized.

When the ENB bit is set to 1, RCR3 performs a comparison with the RYRCNT. From among
RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/RMONAR/RCR3, the counter and alarm
register comparison is performed only on those with ENB bits set to 1, and if each of those
coincides, an alarm flag of RCR1 is set to 1.

to wait for 1/64 of a second.
Clear alarm flag
Enable alarm interrupt
Use a periodic interrupt set up in RCR2 to wait for 1/64 of a second
in the cases shown below.
When recovery from deep standby mode is initiated by an alarm interrupt.
When the ENB bit in an alarm register is set at another time after setting
of the alarm time.
Always reset, since the flag may have been
set while the alarm time was being set.
Write 1 to AIE in RCR1
Monitor alarm time
(wait for interrupt or
check alarm flag)
Figure 14.4 Using Alarm Function
Alarms can be generated using seconds, minutes, hours, day of the week, date, month, year, or any
combination of these. Set the ENB bit in the register on which the alarm is placed to 1, and then
set the alarm time in the lower bits. Clear the ENB bit in the register on which the alarm is not
placed to 0.
When the clock and alarm times match, 1 is set in the AF bit in RCR1. Alarm detection can be
checked by reading this bit, but normally it is done by interrupt. If 1 is set in the AIE bit in RCR1,
an interrupt is generated when an alarm occurs.
The alarm flag is set when the clock and alarm times match. However, the alarm flag can be
cleared by writing 0.

Usage Notes
14.5.1
Register Writing during Count
The following registers cannot be written to during a count (while bit 0 = 1 in RCR2).
RSECCNT, RMINCNT, RHRCNT, RDAYCNT, RWKCNT, RMONCNT, RYRCONT
The count must be stopped before writing to any of the above registers.
14.5.2
Use of Realtime Clock Periodic Interrupts
The method of using the periodic interrupt function is shown in figure 14.5.
A periodic interrupt can be generated periodically at the interval set by bits PES2 to PES0 in
RCR2. When the time set by bits PES2 to PES0 has elapsed, the PEF is set to 1.
The PEF is cleared to 0 upon periodic interrupt generation or when bits PES2 to PES0 are set.
Periodic interrupt generation can be confirmed by reading this bit, but normally the interrupt
function is used.
Set PES, clear PEF
Set PES2 to PES0
and clear PEF to 0

Elapse of time set by PES
Clear PEF
Clear PEF to 0

14.5.3
Transition to Standby Mode after Setting Register
When a transition to standby mode is made after registers in this module are set, sometimes
counting is not performed correctly. After making register settings, do not fail to perform a
dummy read of the registers to which settings were made before entering the standby state.

14.5.4
Section 14 Realtime Clock
Usage Notes when Writing to and Reading the Register
After writing to a count register such as the second counter or to the RCR2 register, perform
two dummy reads before reading from the register. The register value before the write is
returned by the two dummy reads. The value newly written to the register takes effect only on
the third read operation.
Registers other than the above can be read immediately after a write and the written value is
reflected.

Section 15 Serial Communication Interface with FIFO
Section 15 Serial Communication Interface with FIFO
This LSI has an eight-channel serial communication interface with FIFO that supports both
asynchronous and clock synchronous serial communication. It also has 16-stage FIFO registers for
both transmission and reception independently for each channel that enable this LSI to perform
efficient high-speed continuous communication.
15.1
Features
Asynchronous serial communication:
Serial data communication is performed by start-stop in character units. This module can
communicate with a universal asynchronous receiver/transmitter (UART), an asynchronous
communication interface adapter (ACIA), or any other communications chip that employs
a standard asynchronous serial system. There are eight selectable serial data
communication formats.
Data length: 7 or 8 bits
Stop bit length: 1 or 2 bits
Parity: Even, odd, or none
Receive error detection: Parity, framing, and overrun errors
Break detection: Break is detected when a framing error is followed by at least one frame
at the space 0 level (low level). It is also detected by reading the RxD level directly from
the serial port register when a framing error occurs.
Clock synchronous serial communication: (SH7262: channels 0 to 2, SH7264: channels 0 to 3)
Serial data communication is synchronized with a clock signal. This module can
communicate with other chips having a clock synchronous communication function. There
is one serial data communication format.
Data length: 8 bits
Receive error detection: Overrun errors
Full duplex communication: The transmitting and receiving sections are independent, so this
module can transmit and receive simultaneously. Both sections use 16-stage FIFO buffering,
so high-speed continuous data transfer is possible in both the transmit and receive directions.
On-chip baud rate generator with selectable bit rates
Internal or external transmit/receive clock source: From either baud rate generator (internal) or
SCK pin (external)
R01UH0134EJ0400 Rev. 4.00
Sep 24, 2014
Page 707 of 2108
Section 15 Serial Communication Interface with FIFO
SH7262 Group, SH7264 Group
Four types of interrupts: Transmit-FIFO-data-empty interrupt, break interrupt, receive-FIFOdata-full interrupt, and receive-error interrupts are requested independently.
When this module is not in use, it can be stopped by halting the clock supplied to it, saving
power.
In asynchronous mode, on-chip modem control functions (RTS and CTS) (SH7262: channel 1,
SH7264: channels 1 and 3).
The quantity of data in the transmit and receive FIFO data registers and the number of receive
errors of the receive data in the receive FIFO data register can be ascertained.
A time-out error (DR) can be detected when receiving in asynchronous mode.
In asynchronous mode, the base clock frequency can be either 16 or 8 times the bit rate.
When an internal clock is selected as a clock source and the SCK pin is used as an input pin in
asynchronous mode, either normal mode or double-speed mode can be selected for the baud
rate generator.

15.3.1
Section 15 Serial Communication Interface with FIFO
Receive Shift Register (SCRSR)
SCRSR receives serial data. Data input at the RxD pin is loaded into SCRSR in the order received,
LSB (bit 0) first, converting the data to parallel form. When one byte has been received, it is
automatically transferred to the receive FIFO data register (SCFRDR).
The CPU cannot read or write to SCRSR directly.

Receive FIFO Data Register (SCFRDR)
SCFRDR is a 16-byte FIFO register that stores serial receive data. The reception of one byte of
serial data is complete when the received data is moved from the receive shift register (SCRSR) to
SCFRDR for storage. Continuous reception is possible until 16 bytes are stored. The CPU can
read but not write to SCFRDR. If data is read when there is no receive data in the SCFRDR, the
value is undefined.
When SCFRDR is full of receive data, subsequent serial data is lost.

Transmit Shift Register (SCTSR)
SCTSR transmits serial data. Transmit data is loaded from the transmit FIFO data register
(SCFTDR) into SCTSR, then the data is transmitted serially from the TxD pin, LSB (bit 0) first.
After one data byte has been transmitted, the next transmit data is automatically loaded from
SCFTDR into SCTSR and transmission is started again.
The CPU cannot read from or write to SCTSR directly.

Transmit FIFO Data Register (SCFTDR)
SCFTDR is a 16-byte FIFO register that stores data for serial transmission. When the transmit
shift register (SCTSR) empty is detected, transmit data written in the SCFTDR is moved to
SCTSR and serial transmission is started. Continuous serial transmission is performed until there
is no transmit data left in SCFTDR. The CPU can write to SCFTDR at all times.
When SCFTDR is full of transmit data (16 bytes), no more data can be written. If writing of new
data is attempted, the data is ignored.

Serial Status Register (SCFSR)
SCFSR is a 16-bit register. The upper 8 bits indicate the number of receive errors in the receive
FIFO data register, and the lower 8 bits indicate the status flag indicating operating state.
The CPU can always read and write to SCFSR, but cannot write 1 to the status flags (ER, TEND,
TDFE, BRK, RDF, and DR). These flags can be cleared to 0 only if they have first been read
(after being set to 1). The PER flag (bits 15 to 12 and bit 2) and the FER flag (bits 11 to 8 and bit
3) are read-only bits that cannot be written.

[Setting conditions]
ER is set to 1 when the stop bit is 0 after checking
whether or not the last stop bit of the received
data is 1 at the end of one data receive
operation*2
ER is set to 1 when the total number of 1s in the
receive data plus parity bit does not match the
even/odd parity specified by the O/E bit in SCSMR
Notes: 1. Clearing the RE bit to 0 in SCSCR does
not affect the ER bit, which retains its
previous value. Even if a receive error
occurs, the receive data is transferred to
SCFRDR and the receive operation is
continued. Whether or not the data read
from SCFRDR includes a receive error
can be detected by the FER and PER bits
in SCFSR.
2. In two stop bits mode, only the first stop
bit is checked; the second stop bit is not
checked.

R/(W)* Transmit FIFO Data Empty
Description
Indicates that data has been transferred from the
transmit FIFO data register (SCFTDR) to the transmit
shift register (SCTSR), the quantity of data in
SCFTDR has become less than the transmission
trigger number specified by the TTRG[1:0] bits in the
FIFO control register (SCFCR), and writing of transmit
data to SCFTDR is enabled.
0: The quantity of transmit data written to SCFTDR is
greater than the specified transmission trigger
number
[Clearing conditions]
TDFE is cleared to 0 when data exceeding the
specified transmission trigger number is written to
SCFTDR after 1 is read from TDFE and then 0 is
written
TDFE is cleared to 0 when direct memory access
controller is activated by transmit FIFO data empty
interrupt (TXI) and write data exceeding the
specified transmission trigger number to SCFTDR
1: The quantity of transmit data in SCFTDR is less
than or equal to the specified transmission trigger
number*1
[Setting conditions]
TDFE is set to 1 by a power-on reset
TDFE is set to 1 when the quantity of transmit
data in SCFTDR becomes less than or equal to
the specified transmission trigger number as a
result of transmission
Note: 1. Since SCFTDR is a 16-byte FIFO register,
the maximum quantity of data that can be
written when TDFE is 1 is "16 minus the
specified transmission trigger number". If
an attempt is made to write additional
data, the data is ignored. The quantity of
data in SCFTDR is indicated by the upper
8 bits of SCFDR.

receive data.
0: No break signal received
[Clearing conditions]
BRK is cleared to 0 when the chip is a power-on
reset
BRK is cleared to 0 when software reads BRK
after it has been set to 1, then writes 0 to BRK
1: Break signal received*1
[Setting condition]
BRK is set to 1 when data including a framing
error is received, and a framing error occurs with
space 0 in the subsequent receive data
Note: 1. When a break is detected, transfer of the
receive data (H'00) to SCFRDR stops
after detection. When the break ends and
the receive signal becomes mark 1, the
transfer of receive data resumes.

[Setting condition]
RDF is set to 1 when a quantity of receive data
more than the specified receive trigger number is
stored in SCFRDR*1
Note: 1. As SCFTDR is a 16-byte FIFO register,
the maximum quantity of data that can be
read when RDF is 1 becomes the
specified receive trigger number. If an
attempt is made to read after all the data
in SCFRDR has been read, the data is
undefined. The quantity of receive data in
SCFRDR is indicated by the lower 8 bits
of SCFDR.

15.3.8
Bit Rate Register (SCBRR)
SCBRR is an 8-bit register that is used with the CKS1 and CKS0 bits in the serial mode register
(SCSMR) and the BGDM and ABCS bits in the serial extension mode register (SCEMR) to
determine the serial transmit/receive bit rate.
The CPU can always read and write to SCBRR. SCBRR is initialized to H'FF by a power-on reset.
Each channel has independent baud rate generator control, so different values can be set in eight
channels.

15.3.11 Serial Port Register (SCSPTR)
SCSPTR controls input/output and data of pins multiplexed to the functions of this module. Bits 7
and 6 can control input/output data of RTS pin. Bits 5 and 4 can control input/output data of CTS
pin. Bits 3 and 2 can control input/output data of SCK pin. Bits 1 and 0 can input data from RxD
pin and output data to TxD pin, so they control break of serial transmitting/receiving.
The CPU can always read and write to SCSPTR.

Operation
15.4.1
Overview
Section 15 Serial Communication Interface with FIFO
For serial communication, this module has an asynchronous mode in which characters are
synchronized individually, and a clock synchronous mode in which communication is
synchronized with clock pulses. Note that on the SH7262 channels other than 0 to 2, and on the
SH7264 channels other than 0 to 3, cannot be set to clock synchronous mode.
This module has a 16-stage FIFO buffer for both transmission and receptions, reducing the
overhead of the CPU, and enabling continuous high-speed communication. Furthermore, channel
1 on the SH7262, and channels 1 and 3 on the SH7264, have RTS and CTS signals to be used as
modem control signals.
The transmission format is selected in the serial mode register (SCSMR), as shown in table 15.9.
The clock source is selected by the combination of the CKE1 and CKE0 bits in the serial control
register (SCSCR), as shown in table 15.10.
(1)
Asynchronous Mode
Data length is selectable: 7 or 8 bits
Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding
selections constitutes the communication format and character length.
In receiving, it is possible to detect framing errors, parity errors, receive FIFO data full,
overrun errors, receive data ready, and breaks.
The number of stored data bytes is indicated for both the transmit and receive FIFO registers.
An internal or external clock can be selected as the clock source.
When an internal clock is selected, this module operates using the clock of on-chip baud
rate generator.
When an external clock is selected, the external clock input must have a frequency 16 or 8
times the bit rate. (The on-chip baud rate generator is not used.)

Clock Synchronous Mode (SH7262: Channels 0 to 2, SH7264: Channels 0 to 3)
The transmission/reception format has a fixed 8-bit data length.
In receiving, it is possible to detect overrun errors (ORER).
An internal or external clock can be selected as the clock source.
When an internal clock is selected, this module operates using the clock of the on-chip
baud rate generator, and outputs this clock to external devices as the synchronous clock.
When an external clock is selected, this module operates on the input external synchronous
clock not using the on-chip baud rate generator.

15.4.2
Operation in Asynchronous Mode
In asynchronous mode, each transmitted or received character begins with a start bit and ends with
a stop bit. Serial communication is synchronized one character at a time.
The transmitting and receiving sections in this module are independent, so full duplex
communication is possible. The transmitter and receiver are 16-byte FIFO buffered, so data can be
written and read while transmitting and receiving are in progress, enabling continuous transmitting
and receiving.
Figure 15.2 shows the general format of asynchronous serial communication.
In asynchronous serial communication, the communication line is normally held in the mark
(high) state. This module monitors the line and starts serial communication when the line goes to
the space (low) state, indicating a start bit. One serial character consists of a start bit (low), data
(LSB first), parity bit (high or low), and stop bit (high), in that order.
When receiving in asynchronous mode, this module synchronizes at the falling edge of the start
bit. This module samples each data bit on the eighth or fourth pulse of a clock with a frequency 16
or 8 times the bit rate. Receive data is latched at the center of each bit.

Clock
An internal clock generated by the on-chip baud rate generator or an external clock input from the
SCK pin can be selected as the transmit/receive clock. The clock source is selected by the C/A bit
in the serial mode register (SCSMR) and the CKE1 and CKE0 bits in the serial control register
(SCSCR). For clock source selection, refer to table 15.10, SCSMR and SCSCR Settings and Clock
Source Selection.
When an external clock is input at the SCK pin, it must have a frequency equal to 16 or 8 times
the desired bit rate.
When this module operates on an internal clock, it can output a clock signal on the SCK pin. The
frequency of this output clock is 16 or 8 times the desired bit rate.
(3)
Transmitting and Receiving Data
Initialization (Asynchronous Mode)
Before transmitting or receiving, clear the TE and RE bits to 0 in the serial control register
(SCSCR), then initialize this module as follows.
When changing the operation mode or the communication format, always clear the TE and RE
bits to 0 before following the procedure given below. Clearing TE to 0 initializes the transmit
shift register (SCTSR). Clearing TE and RE to 0, however, does not initialize the serial status
register (SCFSR), transmit FIFO data register (SCFTDR), or receive FIFO data register
(SCFRDR), which retain their previous contents. Clear TE to 0 after all transmit data has been
transmitted and the TEND flag in the SCFSR is set. The TE bit can be cleared to 0 during
transmission, but the transmit data goes to the Mark state after the bit is cleared to 0. Set the
TFRST bit in SCFCR to 1 and reset SCFTDR before TE is set again to start transmission.
When an external clock is used, the clock should not be stopped during initialization or
subsequent operation. The operation becomes unreliable if the clock is stopped.

SCK, TxD, RxD
[4]
Set the TE and RE bits in SCSCR to 1,
and set the TIE, RIE, and REIE bits
[5]
End of initialization
[3] Write a value corresponding to the
bit rate into SCBRR. (Not
necessary if an external clock is
used.)
[4] Sets the general I/O port external pins
used. Set as RxD input at receiving
and TxD at transmission.
However, no setting for SCK pin is
required when CKE[1:0] is 00.
In the case when internal synchronous
clock output is set, the SCK pin starts
outputting the clock at this stage.
[5] Set the TE bit or RE bit in SCSCR
to 1. Also set the RIE, REIE, and
TIE bits. Setting the TE and RE bits
enables the TxD and RxD pins to be
used.
When transmitting, the SCIF will go
to the mark state; when receiving,
it will go to the idle state, waiting for
a start bit.

Section 15 Serial Communication Interface with FIFO
In serial transmission, this module operates as described below.
1. When data is written into the transmit FIFO data register (SCFTDR), the data is transferred
from SCFTDR to the transmit shift register (SCTSR). Confirm that the TDFE flag in the serial
status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of
data bytes that can be written is (16 – transmit trigger setting).
2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive
transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the
FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register
(SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is
generated.
The serial transmit data is sent from the TxD pin in the following order.
A. Start bit: One-bit 0 is output.
B. Transmit data: 8-bit or 7-bit data is output in LSB-first order.
C. Parity bit: One parity bit (even or odd parity) is output. (A format in which a parity bit is
not output can also be selected.)
D. Stop bit(s): One or two 1 bits (stop bits) are output.
E. Mark state: 1 is output continuously until the start bit that starts the next transmission is
sent.
3. The SCFTDR transmit data is checked at the timing for sending the stop bit. If data is present,
the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial
transmission of the next frame is started.

SH7264, transmission can be stopped and restarted in accordance with the CTS input value.
When CTS is set to 1, if transmission is in progress, the line goes to the mark state after
transmission of one frame. When CTS is set to 0, the next transmit data is output starting from

Section 15 Serial Communication Interface with FIFO
In serial reception, this module operates as described below.
1. The transmission line is monitored, and if a 0 start bit is detected, internal synchronization is
performed and reception is started.
2. The received data is stored in SCRSR in LSB-to-MSB order.
3. The parity bit and stop bit are received.
After receiving these bits, this module carries out the following checks.
A. Stop bit check: Checks whether the stop bit is 1. If there are two stop bits, only the first is
checked.
B. Checks whether receive data can be transferred from the receive shift register (SCRSR) to
SCFRDR.
C. Overrun check: Checks that the ORER flag is 0, indicating that the overrun error has not
occurred.
D. Break check: Checks that the BRK flag is 0, indicating that the break state is not set.
If all the above checks are passed, the receive data is stored in SCFRDR.
Note: When a parity error or a framing error occurs, reception is not suspended.
4. If the RIE bit in SCSCR is set to 1 when the RDF or DR flag changes to 1, a receive-FIFOdata-full interrupt (RXI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to
1 when the ER flag changes to 1, a receive-error interrupt (ERI) request is generated. If the
RIE bit or the REIE bit in SCSCR is set to 1 when the BRK or ORER flag changes to 1, a
break reception interrupt (BRI) request is generated.

Operation in Clock Synchronous Mode
In clock synchronous mode, data is transmitted and received in synchronization with clock pulses.
This mode is suitable for high-speed serial communication.
The transmitter and receiver in this module are independent, so full-duplex communication is
possible while sharing the same clock. The transmitter and receiver are also 16-byte FIFO
buffered, so continuous transmitting or receiving is possible by reading or writing data while
transmitting or receiving is in progress.

Figure 15.11 Data Format in Clock Synchronous Communication
In clock synchronous serial communication, each data bit is output on the communication line
from one falling edge of the serial clock to the next. Data is guaranteed valid at the rising edge of
the serial clock.
In each character, the serial data bits are transmitted in order from the LSB (first) to the MSB
(last). After output of the MSB, the communication line remains in the state of the MSB.
In clock synchronous mode, data is received in synchronization with the rising edge of the serial
clock.

Transmit/Receive Formats
The data length is fixed at eight bits. No parity bit can be added.
(2)
Clock
An internal clock generated by the on-chip baud rate generator by the setting of the C/A bit in
SCSMR and CKE[1:0] in SCSCR, or an external clock input from the SCK pin can be selected as
the transmit/receive clock.
When this module operates on an internal clock, it outputs the clock signal at the SCK pin. Eight
clock pulses are output per transmitted or received character. When transmission or reception is
not performed, the clock signal remains in the high state. When only receiving, the clock signal
outputs while the RE bit of SCSCR is 1 and the number of data in receive FIFO is more than the
receive FIFO data trigger number.

Transmitting and Receiving Data
Initialization (Clock Synchronous Mode)
Before transmitting, receiving, or changing the mode or communication format, the software
must clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize this
module. Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing RE to 0,
however, does not initialize the RDF, PER, FER, and ORER flags and receive data register
(SCRDR), which retain their previous contents.

Section 15 Serial Communication Interface with FIFO
In serial transmission, this module operates as described below.
1. When data is written into the transmit FIFO data register (SCFTDR), the data is transferred
from SCFTDR to the transmit shift register (SCTSR). Confirm that the TDFE flag in the serial
status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of
data bytes that can be written is (16 – transmit trigger setting).
2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive
transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the
FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register
(SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is
generated.
If clock output mode is selected, eight synchronous clock pulses are output. If an external
clock source is selected, data is output in synchronization with the input clock. Data is output
from the TxD pin in order from the LSB (bit 0) to the MSB (bit 7).
3. The SCFTDR transmit data is checked at the timing for sending the MSB (bit 7). If data is
present, the data is transferred from SCFTDR to SCTSR, and then serial transmission of the
next frame is started. If there is no data, the TxD pin holds the state after the TEND flag in
SCFSR is set to 1 and the MSB (bit 7) is sent.
4. After the end of serial transmission, the SCK pin is held in the high state.

Figure 15.16 Sample Flowchart for Receiving Serial Data (2)
In serial reception, this module operates as described below.
1. Reception is started in synchronization with serial clock input or output.
2. Receive data is shifted into SCRSR in order from the LSB to the MSB. After the data
reception, whether the receive data can be loaded from SCRSR into SCFRDR or not is
checked. If this check is passed, the RDF flag is set to 1 and the received data is stored in
SCFRDR. If the check is not passed (overrun error is detected), further reception is prevented.
3. After setting RDF to 1, if the receive FIFO data full interrupt enable bit (RIE) is set to 1 in
SCSCR, a receive-data-full interrupt (RXI) request is generated. If the ORER bit is set to 1 and
the receive-data-full interrupt enable bit (RIE) or the receive error interrupt enable bit (REIE)
in SCSCR is also set to 1, a break interrupt (BRI) request is generated.

Interrupts
This module has four interrupt sources: transmit-FIFO-data-empty (TXI), receive-error (ERI),
receive FIFO data full (RXI), and break (BRI).
Table 15.12 shows the interrupt sources and their order of priority. The interrupt sources are
enabled or disabled by means of the TIE, RIE, and REIE bits in SCSCR. A separate interrupt
request is sent to the interrupt controller for each of these interrupt sources.
When a TXI request is enabled by the TIE bit and the TDFE flag in the serial status register
(SCFSR) is set to 1, a TXI interrupt request is generated. The direct memory access controller can
be activated and data transfer performed by this TXI interrupt request. At this time, an interrupt
request is not sent to the CPU.
When an RXI request is enabled by the RIE bit and the RDF flag or the DR flag in SCFSR is set
to 1, an RXI interrupt request is generated. The direct memory access controller can be activated
and data transfer performed by this RXI interrupt request. At this time, an interrupt request is not
sent to the CPU. The RXI interrupt request caused by the DR flag is generated only in
asynchronous mode.
It is possible to generate only the ERI or BRI interrupt without generating the RXI interrupt by
setting the RIE bit to 0 and the REIE bit to 1 in SCSCR.
The TXI indicates that transmit data can be written, and the RXI indicates that there is receive data
in SCFRDR.

Section 15 Serial Communication Interface with FIFO
Usage Notes
Note the following when using this module.
15.6.1
SCFTDR Writing and TDFE Flag
The TDFE flag in the serial status register (SCFSR) is set when the number of transmit data bytes
written in the transmit FIFO data register (SCFTDR) has fallen below the transmit trigger number
set by bits TTRG[1:0] in the FIFO control register (SCFCR). After the TDFE flag is set, transmit
data up to the number of empty bytes in SCFTDR can be written, allowing efficient continuous
transmission.
However, if the number of data bytes written in SCFTDR is equal to or less than the transmit
trigger number, the TDFE flag will be set to 1 again after being read as 1 and cleared to 0. TDFE
flag clearing should therefore be carried out when SCFTDR contains more than the transmit
trigger number of transmit data bytes.
The number of transmit data bytes in SCFTDR can be found from the upper 8 bits of the FIFO
data count register (SCFDR).
15.6.2
SCFRDR Reading and RDF Flag
The RDF flag in the serial status register (SCFSR) is set when the number of receive data bytes in
the receive FIFO data register (SCFRDR) has become equal to or greater than the receive trigger
number set by bits RTRG[1:0] in the FIFO control register (SCFCR). After RDF flag is set,
receive data equivalent to the trigger number can be read from SCFRDR, allowing efficient
continuous reception.
However, if the number of data bytes in SCFRDR exceeds the trigger number, the RDF flag will
be set to 1 again if it is cleared to 0. The RDF flag should therefore be cleared to 0 after being read
as 1 after reading the number of the received data in the receive FIFO data register (SCFRDR)
which is less than the trigger number.
The number of receive data bytes in SCFRDR can be found from the lower 8 bits of the FIFO data
count register (SCFDR).

15.6.3
SH7262 Group, SH7264 Group
Restriction on Direct Memory Controller Usage
When the direct memory access controller writes data to SCFTDR due to a TXI interrupt request,
the state of the TEND flag becomes undefined. Therefore, the TEND flag should not be used as
the transfer end flag in such a case.
15.6.4
Break Detection and Processing
Break signals can be detected by reading the RxD pin directly when a framing error (FER) is
detected. In the break state the input from the RxD pin consists of all 0s, so the FER flag is set and
the parity error flag (PER) may also be set.
Note that, although transfer of receive data to SCFRDR is halted in the break state, the receive
operation is continued.
15.6.5
Sending a Break Signal
The I/O condition and level of the TxD pin are determined by the SPB2IO and SPB2DT bits in the
serial port register (SCSPTR). This feature can be used to send a break signal.
Until TE bit is set to 1 (enabling transmission) after initializing, the TxD pin does not work.
During the period, mark status is performed by the SPB2DT bit. Therefore, the SPB2IO and
SPB2DT bits should be set to 1 (high level output).
To send a break signal during serial transmission, clear the SPB2DT bit to 0 (designating low
level), then clear the TE bit to 0 (halting transmission). When the TE bit is cleared to 0, the
transmitter is initialized regardless of the current transmission state, and 0 is output from the TxD
pin.
15.6.6
Receive Data Sampling Timing and Receive Margin (Asynchronous Mode)
This module operates on a base clock with a frequency 16 or 8 times the bit rate. In reception, the
falling edge of the start bit is sampled at the base clock to perform synchronization internally.
Receive data is latched at the rising edge of the eighth or fourth base clock pulse. When this
module operates on a base clock with a frequency 16 times the bit rate, the receive data is sampled
at the timing shown in figure 15.19.

Figure 15.19 Receive Data Sampling Timing in Asynchronous Mode
(Operation on a Base Clock with a Frequency 16 Times the Bit Rate)
The receive margin in asynchronous mode can therefore be expressed as shown in equation 1.
Equation 1:
M = (0.5 −
D − 0.5
1
) − (L − 0.5) F −
(1 + F) × 100 %
2N
N
Where: M: Receive margin ()
N: Ratio of clock frequency to bit rate (N = 16 or 8)
D: Clock duty (D = 0 to 1.0)
L: Frame length (L = 9 to 12)
F: Absolute deviation of clock frequency
From equation 1, if F = 0, D = 0.5 and N = 16, the receive margin is 46.875, as given by
equation 2.
Equation 2:
When D = 0.5 and F = 0:
M = (0.5 − 1/(2 × 16)) × 100%
= 46.875%
This is a theoretical value. A reasonable margin to allow in system designs is 20 to 30.

Selection of Base Clock in Asynchronous Mode
In this LSI, when asynchronous mode is selected, the base clock frequency within a bit period can
be set to the frequency 16 or 8 times the bit rate by setting the ABCS bit in SCEMR.
Note that, however, if the base clock frequency 8 times the bit rate is used, receive margin is
decreased as calculated using equation 1 in section 15.6.6, Receive Data Sampling Timing and
Receive Margin (Asynchronous Mode).
If the desired bit rate can be set simply by setting SCBRR and the CKS1and CKS0 bits in
SCSMR, it is recommended to use the base clock frequency within a bit period 16 times the bit
rate (by setting the ABCS bit in SCEMR to 0). If an internal clock is selected as a clock source
and the SCK pin is not used, the bit rate can be increased without decreasing receive margin by
selecting double-speed mode for the baud rate generator (setting the BGDM bit in SCEMR to 1).

R/(W)* Mode Fault Error Flag
Description
Indicates the occurrence of a mode fault error. If the
MODFEN bit is set to 1 when this module is in slave
mode and the SSL pin is negated before the RSPCK
cycle necessary for data transfer ends, this module
detects a mode fault error. The active level of the
SSL signal is determined by the SSL0P bit in the
slave select polarity register (SSLP).
[Clearing conditions]
SPSR is read when the MODF bit is 1, and then
0 is written to the MODF bit.
Power-on reset
0: No mode fault error occurred
1: A mode fault error occurred
Note: This bit is valid only in SPI slave mode.

overrun error, and sets the OVRF bit to 1.
[Clearing conditions]
SPSR is read when the OVRF bit is 1, and then 0
is written to the OVRF bit.
Power-on reset

16.3.5
Section 16 Renesas Serial Peripheral Interface
Data Register (SPDR)
SPDR is a buffer that holds data for transmission and reception.
The transmit buffer (SPTX) and receive buffer (SPRX) are independent and are mapped to SPDR.
SPDR should be read or written to in byte, word, or longword units according to the access width
specification bit (SPLW) in the data control register (SPDCR).
The bit length to be used is determined by the data length specification bits (SPB3 to SPB0) in the
command register (SPCMD).
When data is written to SPDR, the data will be written to the transmit buffer from SPDR if the
transmit buffer has a space equal to or more than the SPDR access width. If there is not enough
space, data will not be written to the transmit buffer. Even if an attempt is made to write data to
the buffer, the data is ignored.
When data is read from SPDR, receive data in the receive buffer will be read. If SPDR is read
when there is no receive data in the receive buffer, the read value is undefined.
When SPDR is written to with the longword-, word-, or byte-access width, the transmit data
should be written to the following bits. If data is written to the other bits, the data is not
guaranteed.
Longword: Bits 31 to 0
Word: Bits 31 to 16
Byte: Bits 31 to 24
When SPDR is read with the longword-, word-, or byte-access width, the receive data should be
read from the following bits. If data is read from the other bits, the data is not guaranteed.
Longword: Bits 31 to 0
Word: Bits 31 to 16
Byte: Bits 31 to 24

When this module is used in slave mode, the bit rate depends on the bit rate of the input clock
regardless of the settings of SPBR and BRDV.
The bit rate is determined by combinations of SPBR settings and the bit settings in the BRDV1
and BRDV0 bits in the command registers (SPCMD0 to SPCMD3). The equation for calculating
the bit rate is given below. In the equation, n denotes an SPBR setting (0, 1, 2, …, 255), and N
denotes bit settings in the bits BRDV1 and BRDV0 (0, 1, 2, 3).

Bit rate =

16.3.13 Command Register (SPCMD)
Each channel has four command registers (SPCMD0 to SPCMD3). SPCMD0 to SPCMD3 are
used to set a transfer format for master mode operation. Some of the bits in SPCMD0 are used to
set a transfer mode for slave mode operation. In master mode, this module sequentially references
SPCMD0 to SPCMD3 according to the settings in bits SPSLN1 and SPSLN0 in the sequence
control register (SPSCR), and executes the serial transfer that is set in the referenced SPCMD.
While bit TEND in the status register (SPSR) indicates that transmission is not completed, correct
operation of this module cannot be guaranteed if SPCMD is changed that is referred by this
module. SPCMD referenced by this module in master mode can be checked by means of bits
SPCP1 and SPCP0 in the sequence status register (SPSSR). When the function of this module in
master mode is enabled, operation cannot be guaranteed if the value set in SPCMD0 is changed.

These bits are used to determine the bit rate. A bit
rate is determined by combinations of bits BRDV1
and BRDV 0 and the settings in the bit rate register
(SPBR) (see section 16.3.8, Bit Rate Register
(SPBR)). The settings in SPBR determine the base
bit rate. The settings in bits BRDV1 and BRDV0 are
used to select a bit rate which is obtained by dividing
the base bit rate by 1, 2, 4, or 8. In the bits SPCMD0
to SPCMD3, different BRDV1 and BRDV0 settings
can be specified. This permits the execution of serial
transfers at a different bit rate for each command.

System Configuration Example
Master/Slave (with This LSI Acting as Master)
Figure 16.2 shows a master/slave system configuration example when this LSI is used as a master.
In master/slave configuration, the SSL output of this LSI (master) is not used. The SSL input of
the slave is fixed to the low level, and the slave is always maintained in a selected state. In the
transfer format corresponding to the case where the CPHA bit in the control register (SPCR) is 0,
there are slave devices for which the SSL signal cannot be fixed to the active level. In situations
where the SSL signal cannot be fixed, the SSL output of this LSI should be connected to the SSL
input of the slave device.
This LSI (master) always drives the RSPCK and MOSI. The slave always drives the MISO.

Master/Slave (with This LSI Acting as Slave)
Figure 16.3 shows a master/slave system configuration example when this LSI is used as a slave.
When this LSI is to operate as a slave, the SSL pin is used as SSL input. The master always drives
the RSPCK and MOSI. This LSI (slave) always drives the MISO. When SSL is at the non-active
level, the pin state is Hi-Z.
In the slave configuration in which the CPHA bit in the command register (SPCMD) is set to 1,
the SSL input of this LSI (slave) is fixed to the 0 level, this LSI (slave) is always maintained in a
selected state, and in this manner it is possible to execute serial transfer (figure 16.4).

Master/Multi-Slave (with This LSI Acting as Slave)
Figure 16.5 shows a master/multi-slave system configuration example when this LSI is used as a
slave. In the example of figure 16.5, the system is comprised of an master and two LSIs (slave X
and slave Y).
The RSPCK and MOSI outputs of the master are connected to the RSPCK and MOSI inputs of the
LSIs (slave X and slave Y). The MISO outputs of the LSIs (slave X and slave Y) are all connected
to the MISO input of the master. SSLX and SSLY outputs of the master are connected to the SSL
inputs of the LSIs (slave X and slave Y), respectively.
The master always drives RSPCK, MOSI, SSLX, and SSLY. Of the LSIs (slave X and slave Y),
the slave that receives low level input into the SSL0 input drives MISO.

Transfer Format
CPHA = 0
Figure 16.6 shows a sample transfer format for the serial transfer of 8-bit data when the CPHA bit
in the command register (SPCMD) is 0. In figure 16.6, RSPCK (CPOL = 0) indicates the RSPCK
signal waveform when the CPOL bit in SPCMD is 0; RSPCK (CPOL = 1) indicates the RSPCK
signal waveform when the CPOL bit is 1. The sampling timing represents the timing at which this
module fetches serial transfer data into the shift register. The input/output directions of the signals
depend on the settings of this module. For details, see section 16.4.2, Pin Control.
When the CPHA bit is 0, the driving of valid data to the MOSI and MISO signals commences at
an SSL signal assertion timing. The first RSPCK signal change timing that occurs after the SSL
signal assertion becomes the first transfer data fetching timing. After this timing, data is sampled
at every 1 RSPCK cycle. The change timing for MOSI and MISO signals is always 1/2 RSPCK
cycle after the transfer data fetch timing. The settings in the CPOL bit do not affect the RSPCK
signal operation timing; they only affect the signal polarity.
t1 denotes a period from an SSL signal assertion to RSPCK oscillation (RSPCK delay). t2 denotes
a period from the cessation of RSPCK oscillation to an SSL signal negation (SSL negation delay).
t3 denotes a period in which SSL signal assertion is suppressed for the next transfer after the end
of serial transfer (next-access delay). t1, t2, and t3 are controlled by a master device running on
the system. For a description of t1, t2, and t3 when this module is in master mode, see section
16.4.3 (1), Master/Slave (with This LSI Acting as Master).

CPHA = 1
Figure 16.7 shows a sample transfer format for the serial transfer of 8-bit data when the CPHA bit
in the command register (SPCMD) is 1. In figure 16.7, RSPCK (CPOL = 0) indicates the RSPCK
signal waveform when the CPOL bit in SPCMD is 0; RSPCK (CPOL = 1) indicates the RSPCK
signal waveform when the CPOL bit is 1. The sampling timing represents the timing at which this
module fetches serial transfer data into the shift register. The input/output directions of the signals
depend on the modes (master or slave). For details, see section 16.4.2, Pin Control.
When the CPHA bit is 1, the driving of invalid data to the MOSI and MISO signals commences at
an SSL signal assertion timing. The driving of valid data to the MOSI and MISO signals
commences at the first RSPCK signal change timing that occurs after the SSL signal assertion.
After this timing, data is updated at every 1 RSPCK cycle. The transfer data fetch timing is always
1/2 RSPCK cycle after the data update timing. The settings in the CPOL bit do not affect the
RSPCK signal operation timing; they only affect the signal polarity.
t1, t2, and t3 are the same as those in the case of CPHA = 0. For a description of t1, t2, and t3
when this module is in master mode, see section 16.4.3 (1), Master/Slave (with This LSI Acting as

Section 16 Renesas Serial Peripheral Interface
Data Format
The data format depends on the settings in the command register (SPCMD). Irrespective of
MSB/LSB first, this module treats the range from the LSB of the data register (SPDR) to the
assigned data length as transfer data.
(1)
MSB First Transfer (32-Bit Data)
Figure 16.8 shows the operation of the transmit buffer (SPTX) and the shift register when this
module performs a 32-bit data length MSB-first data transfer.
The CPU or direct memory access controller writes T31 to T00 to the transmit buffer of SPDR. If
the shift register is empty, this module copies the data in the transmit buffer to the shift register,
and fully populates the shift register. When serial transfer starts, this module outputs data from the
MSB (bit 31) of the shift register, and shifts in the data from the LSB (bit 0) of the shift register.
When the RSPCK cycle required for the serial transfer of 32 bits has passed, data R31 to R00 is
stored in the shift register. In this state, this module copies the data from the shift register to the
receive buffer, and empties the shift register. If the receive buffer does not have a space for the
receive data length after the receive data has been copied from the shift register to the receive
buffer, another serial transfer will not be started. In order to start another serial transfer, data for
the receive data length should be read from the receive buffer to secure the necessary space in the
receive buffer.
If another serial transfer is started before the CPU or direct memory access controller writes to the
transmit buffer, received data R31 to R00 is shifted out from the shift register.

MSB First Transfer (16-Bit Data)
Figure 16.9 shows the operation of the transmit buffer (SPTX) and the shift register when this
module performs a 16-bit data length MSB-first data transfer.
The CPU or direct memory access controller writes T15 to T00 to the transmit buffer. If the shift
register is empty, this module copies the data in the transmit buffer to the shift register, and fully
populates the shift register. When serial transfer starts, this module outputs data from bit 15 of the
shift register, and shifts in the data from the LSB (bit 0) of the shift register. When the RSPCK
cycle required for the serial transfer of 16 bits has passed, received data R15 to R00 is stored in
bits 15 to 0 of the shift register. After completion of the serial transfer, data that existed before the
transfer is retained in bits 31 to 16 in the shift register. In this state, this module copies the data
from the shift register to the receive buffer, and empties the shift register. If the receive buffer
does not have a space for the receive data length after receive data has been copied from the shift
register to the receive buffer, another serial transfer will not be started. In order to start another
serial transfer, data for the receive data length should be read from the receive buffer to secure the
necessary space in the receive buffer.
If another serial transfer is started before the CPU or direct memory access controller writes to the

MSB First Transfer (8-Bit Data)
Figure 16.10 shows the operation of the transmit buffer (SPDR) and the shift register when this
module performs an 8-bit data length MSB-first data transfer.
The CPU or direct memory access controller writes T07 to T00 to the transmit buffer. If the shift
register is empty, this module copies the data in the transmit buffer to the shift register, and fully
populates the shift register. When serial transfer starts, this module outputs data from bit 7 of the
shift register, and shifts in the data from the LSB (bit 0) of the shift register. When the RSPCK
cycle required for the serial transfer of 8 bits has passed, received data R07 to R00 is stored in bits
7 to 0 of the shift register. After completion of the serial transfer, data that existed before the
transfer is retained in bits 31 to 8 in the shift register. In this state, this module copies the data
from the shift register to the receive buffer, and empties the shift register. If the receive buffer
does not have a space for the receive data length after receive data has been copied from the shift
register to the receive buffer, another serial transfer will not be started. In order to start another
serial transfer, data for the receive data length should be read from the receive buffer to secure the
necessary area in the receive buffer.
If another serial transfer is started before the CPU or direct memory access controller writes to the
transmit buffer, received data R07 to R00 is shifted out from the shift register.

LSB First Transfer (32-Bit Data)
Figure 16.11 shows the operation of the transmit buffer (SPTX) and the shift register when this
module performs a 32-bit data length LSB-first data transfer.
The CPU or direct memory access controller writes T31 to T00 to the transmit buffer. If the shift
register is empty, this module reverses the order of the bits of the data in the transmit buffer,
copies it to the shift register, and fully populates the shift register. When serial transfer starts, this
module outputs data from the MSB (bit 31) of the shift register, and shifts in the data from the
LSB (bit 0) of the shift register. When the RSPCK cycle required for the serial transfer of 32 bits
has passed, data R00 to R31 is stored in the shift register. In this state, this module copies the data,
in which the order of the bits is reversed, from the shift register to the receive buffer, and empties
the shift register.
If the receive buffer does not have a space for the receive data length after receive data has been
copied from the shift register to the receive buffer, another serial transfer will not be started. In
order to start another serial transfer, data for the receive data length should be read from the
receive buffer to secure the necessary space in the receive buffer.
If another serial transfer is started before the CPU or direct memory access controller writes to the
transmit buffer of the SPDR, received data R00 to R31 is shifted out from the shift register.

LSB First Transfer (16-Bit Data)
Figure 16.12 shows the operation of the transmit buffer (SPTX) and the shift register when this
module performs a 16-bit data length LSB-first data transfer.
The CPU or direct memory access controller writes T15 to T00 to the transmit buffer. If the shift
register is empty, this module reverses the order of the bits of the data in the transmit buffer,
copies it to the shift register, and fully populates the shift register. When serial transfer starts, this
module outputs data from the MSB (bit 31) of the shift register, and shifts in the data from bit 16
of the shift register. When the RSPCK cycle required for the serial transfer of 16 bits has passed,
received data R00 to R15 is stored in bits 31 to 16 of the shift register. After completion of the
serial transfer, data that existed before the transfer is retained in bits 15 to 0 of the shift register. In
this state, this module copies the data, in which the order of the bits is reversed, from the shift
register to the receive buffer of SPDR, and empties the shift register.
If the receive buffer does not have a space for the receive data length after receive data has been

LSB First Transfer (8-Bit Data)
Figure 16.13 shows the operation of the transmit buffer (SPTX) and the shift register when this
module performs an 8-bit data length LSB-first data transfer.
The CPU or direct memory access controller writes T07 to T00 to the transmit buffer. If the shift
register is empty, this module reverses the order of the bits of the data in the transmit buffer,
copies it to the shift register, and fully populates the shift register. When serial transfer starts, this
module outputs data from the MSB (bit 31) of the shift register, and shifts in the data from bit 24
of the shift register. When the RSPCK cycle required for the serial transfer of 8 bits has passed,
received data R00 to R07 is stored in bits 31 to 24 of the shift register. After completion of the
serial transfer, data that existed before the transfer is retained in bits 23 to 0 of the shift register. In
this state, this module copies the data, in which the order of the bits is reversed, from the shift
register to the receive buffer of SPDR, and empties the shift register.
If the receive buffer does not have a space for the receive data length after the receive data has

In order to start another serial transfer, data for the receive data length should be read from the

Section 16 Renesas Serial Peripheral Interface
Error Detection
In the normal serial transfer, the data written from the data register (SPDR) to the transmit buffer
is serially transmitted, and the serially received data can be read from the receive buffer of SPDR.
If access is made to SPDR, depending on the status of the transmit buffer/receive buffer or the
status at the beginning or end of serial transfer, in some cases non-normal transfers can be
executed.
If a non-normal transfer operation occurs, this module detects the event as an overrun error or a
mode fault error. Table 16.7 shows the relationship between non-normal transfer operations and
the error detection function.

On operation A shown in table 16.7, this module does not detect an error. Whether SPDR can be
written to or not can be checked using the T[3:0] bits in the buffer data count setting register
(SPBFDR).
Likewise, this module does not detect an error on operation B. In a serial transfer that was started
before the shift register was updated, this module sends the data that was received in the previous
serial transfer, and does not treat the operation indicated in B as an error. Note that the received
data from the previous serial transfer is retained in the receive buffer of SPDR, thus it can be
correctly read.
Similarly, this module does not detect an error on operation C. To prevent extraneous data from
being read, the number of receive data units stored in the receive buffer should be read from the
R[5:0] bits in the buffer data count setting register (SPBFDR).
An overrun error shown in D is described in section 16.4.6 (1), Overrun Error. A mode fault error
shown in E is described in section 16.4.6 (2), Mode Fault Error.

Section 16 Renesas Serial Peripheral Interface
Overrun Error
If serial transfer ends when the receive buffer of the data register (SPDR) is full, this module
detects an overrun error, and sets the OVRF bit in SPSR to 1. When the OVRF bit is 1, this
module does not copy data from the shift register to the receive buffer so that the data prior to the
occurrence of the error is retained in the receive buffer. To reset the OVRF bit in SPSR to 0, either
perform a power-on reset, or write a 0 to the OVRF bit after SPSR has been read with the OVRF
bit set to 1.
Figure 16.14 shows an example of operation of the SPRF and OVRF bits in SPSR. The SPSR and
SPDR accesses shown in figure 16.14 indicates the condition of accesses to SPSR and SPDR,
respectively, where I denotes an idle cycle, W a write cycle, and R a read cycle. In the example of
figure 16.14, this module performs an 8-bit serial transfer in which the CPHA bit in the command
register (SPCMD) is 1, and CPOL is 0. The numbers given under the RSPCK waveform represent
the number of RSPCK cycles (i.e., the number of transferred bits).

The operation of the flags at the timing shown in steps (1) to (4) in the figure is described below.
1. If a serial transfer terminates when the receive buffer does not have a space for the receive data
length, this module detects an overrun error, and sets the OVRF bit to 1. This module does not
copy the data in the shift register to the receive buffer.
2. The OVFR bit is not cleared even when SPDR is read and thus the number of data bytes in the
receive buffer becomes less than the number of the receive buffer data triggering number
specified by the RXTRG bits.
3. If the serial transfer terminates in an overrun error state, this module determines that the shift
register is empty; in this manner, data transfer is enabled from the transmit buffer to the shift
register.
4. If 0 is written to the OVRF bit after SPSR is read with OVRF = 1, this module clears the
OVRF bit.
The occurrence of an overrun can be checked either by reading SPSR or by using an error
interrupt and reading SPSR. When using an error interrupt, set the SPEIE bit in the control register
(SPCR) to 1. When executing a serial transfer without using an error interrupt, measures should be
taken to ensure the early detection of overrun errors, such as reading SPSR immediately after
SPDR is read.
The OVRF bit is cleared to 0 under the following conditions:
After SPSR is read in a condition in which the OVRF bit is set to 1, 0 is written to the OVRF
bit.
Power-on reset
Note: When the receive buffer has area enough to store receive data with an overrun error, this
module receives receive data.

Mode Fault Error
When the MSTR bit is 0, this module operates in slave mode. This module detects a mode fault
error if the SSL input signal is negated during the serial transfer period (from the time the driving
of valid data is started to the time the final valid data is fetched) when the MODFEN bit is 1 in
slave mode.
Upon detecting a mode fault error, this module stops driving of the output signals and clears the
SPE bit in SPCR to 0. When the SPE bit is cleared to 0, the function of this module is disabled and
this module stops driving external signals. For details of disabling the function of this module by
clearing the SPE bit to 0, see section 16.4.7, Initialization.
The occurrence of a mode fault error can be checked either by reading SPSR or by using an error
interrupt and reading SPSR. When using an error interrupt, set the SPEIE bit in the control register
(SPCR) to 1. To detect a mode fault error without using an error interrupt, it is necessary to poll
SPSR.
When the MODF bit is 1, writing 1 to the SPE bit is ignored. To enable the function of this
module after the detection of a mode fault error, the MODF bit must be set to 0. The MODF bit is
cleared to 0 under the following conditions:
After SPSR is read in a condition where the MODF bit has turned 1, 0 is written to the MODF
bit.

Initialization
If 0 is written to the SPE bit in the control register (SPCR) or this module clears the SPE bit to 0
because of the detection of a mode fault error, this module disables the module function, and
initializes a part of the module function. When a power-on reset is generated, this module
initializes all of the module function. An explanation of initialization by the clearing of the SPE bit
follows.
(1)
Initialization by Clearing SPE Bit
When the SPE bit in SPCR is cleared, this module performs the following initialization:
Suspending any serial transfer that is being executed
Stopping the driving of output signals (Hi-Z) in slave mode
Initializing the internal state
Initializing the TEND bit in SPSR
Initialization by the clearing of the SPE bit does not initialize the control bits of this module. For
this reason, this module can be started in the same transfer mode as prior to the initialization if the
SPE bit is re-set to 1.

Section 16 Renesas Serial Peripheral Interface
SPI Operation
Multi-Master Mode Operation
This section explains the operation in multi-master mode.
(a)
Starting Serial Transfer
A serial transfer is started when transmit data is copied from the transmit buffer to the shift
register, the shift register becomes full, and the receive buffer has a space for the receive data
length. If transmit data has already been written to the shift register, data is not copied from the
transmit buffer to the shift register.
For details of the transfer format, see section 16.4.4, Transfer Format.
(b)
Terminating Serial Transfer
Irrespective of the CPHA bit in the command register (SPCMD), this module terminates the serial
transfer after transmitting an RSPCK edge corresponding to the final sampling timing. After the
serial transfer is completed, receive data is copied from the shift register to the receive buffer. If
the receive buffer does not have a space for the receive data length after receive data is copied
from the shift register to the receive buffer, another serial transfer will not be performed. In order
to perform another serial transfer, data for the receive data length should be read from the receive
buffer to secure the space for the receive data.
It should be noted that the final sampling timing varies depending on the bit length of transfer
data. In master mode, the data length depends on the settings in bits SPB3 to SPB0 in SPCMD.
For details on the transfer format, see section 16.4.4, Transfer Format.

Section 16 Renesas Serial Peripheral Interface
(c)
Sequence Control
The transfer format that is employed in master mode is determined by the sequence control
register (SPSCR), command registers 0 to 3 (SPCMD0 to SPCMD3), the bit rate register (SPBR),
the clock delay register (SPCKD), the slave select negation delay register (SSLND), and the nextaccess delay register (SPND).
SPSCR is a register used to determine the sequence configuration for serial transfers that are
executed by this module in master mode. The following items are set in command registers
SPCMD0 to SPCMD3: SSL output signal value, MSB/LSB first, data length, some of the bit rate
settings, RSPCK polarity/phase, whether SPCKD is to be referenced, whether SSLND is to be
referenced, and whether SPND is to be referenced. SPBR holds some of the bit rate settings;
SPCKD, a clock delay value; SSLND, an SSL negation delay; and SPND, a next-access delay
value.
According to the sequence length that is assigned to SPSCR, this module makes up a sequence
comprised of a part or all of SPCMD0 to SPCMD3. This module contains a pointer to the SPCMD
that makes up the sequence. The value of this pointer can be checked by reading bits SPCP1 and
SPCP0 in the sequence status register (SPSSR). When the SPE bit in the control register (SPCR) is
set to 1 and the function of this module is enabled, this module loads the pointer to the commands
in SPCMD0, and incorporates the SPCMD0 settings into the transfer format at the beginning of
serial transfer. This module increments the pointer each time the next-access delay period for a
data transfer ends. Upon completion of the serial transfer that corresponds to the final command
comprising the sequence, this module sets the pointer in SPCMD0, and in this manner the
sequence is executed repeatedly.

Burst Transfer
If the SSLKP bit in the command register (SPCMD) that this module references during the current
serial transfer is 1, this module keeps the SSL signal level during the serial transfer until the
beginning of the SSL signal assertion for the next serial transfer. If the SSL signal level for the
next serial transfer is the same as the SSL signal level for the current serial transfer, this module
can execute continuous serial transfers while keeping the SSL signal assertion status (burst
transfer).
Figure 16.16 shows an example of an SSL signal operation for the case where a burst transfer is
implemented using SPCMD0 and SPCMD1 settings. The text below explains operations (1) to (7)
as depicted in figure 16.16. It should be noted that the polarity of the SSL output signal depends
on the settings in the slave select polarity register (SSLP).

4.
Based on SPCMD0, this module asserts the SSL signal and inserts RSPCK delays.
Serial transfers are executed according to SPCMD0.
SSL negation delays are inserted.
Because the SSLKP bit in SPCMD0 is 1, this module keeps the SSL signal value on SPCMD0.
This period is sustained, at the shortest, for a period equal to the next-access delay of
SPCMD0. If the shift register is empty after the passage of a minimum period, this period is
sustained until such time as the transmit data is stored in the shift register for another transfer.
5. Based on SPCMD1, this module asserts the SSL signal and inserts RSPCK delays.
6. Serial transfers are executed according to SPCMD1.
7. Because the SSLKP bit in SPCMD1 is 0, this module negates the SSL signal. In addition, a
next-access delay is inserted according to SPCMD1.

Section 16 Renesas Serial Peripheral Interface
If the SSL signal settings in the SPCMD in which 1 is assigned to the SSLKP bit are different
from the SSL signal output settings in the SPCMD to be used in the next transfer, this module
switches the SSL signal status to SSL signal assertion ((5) in figure 16.16) corresponding to the
command for the next transfer. Notice that if such an SSL signal switching occurs, the slaves that
drive the MISO signal compete, and the possibility arises of the collision of signal levels.
This module in master mode references within the module the SSL signal operation for the case
where the SSLKP bit is not used. Even when the CPHA bit in SPCMD is 0, this module can
accurately start serial transfers by asserting the SSL signal for the next transfer. For this reason,
burst transfers in master mode can be executed irrespective of CPHA bit settings (see section
16.4.8 (2), Slave Mode Operation).
(e)
RSPCK Delay (t1)
The RSPCK delay value in master mode depends on SCKDEN bit settings in the command
register (SPCMD) and on clock delay register (SPCKD) settings. This module determines the
SPCMD to be referenced during serial transfer by pointer control, and determines an RSPCK
delay value during serial transfer by using the SCKDEN bit in the selected SPCMD and SPCKD,
as shown in table 16.8. For a definition of RSPCK delay, see section 16.4.4, Transfer Format.

The SSL negation delay value in master mode depends on SLNDEN bit settings in the command

the SPCMD to be referenced during serial transfer by pointer control, and determines an SSL
negation delay value during serial transfer by using the SLNDEN bit in the selected SPCMD and

Slave Mode Operation
(a)
Starting Serial Transfer
Section 16 Renesas Serial Peripheral Interface
If this module detects an SSL input signal assertion when the CPHA bit in the command register 0
(SPCMD0) is 0, this module is required to start driving valid data to the MISO output signal. For
this reason, when the CPHA bit is 0, the asserting of the SSL input signal triggers the start of a
serial transfer.
If this module detects the first RSPCK edge in an SSL signal asserted condition when the CPHA
bit is 1, this module is required to start driving valid data to the MISO output signal. For this
reason, when the CPHA bit is 1, the first RSPCK edge in an SSL signal asserted condition triggers
the start of a serial transfer.
When detecting the start of a serial transfer in a condition in which the shift register is empty, this
module changes the status of the shift register to "full", so that data cannot be copied from the
transmit buffer to the shift register when serial transfer is in progress. If the shift register was full
before the serial transfer started, this module leaves the status of the shift register intact, in the full
state.
Irrespective of CPHA bit settings, this module starts driving MISO output signals at the SSL
signal assertion timing. Whether the data output from this module is valid or invalid differs
depending on CPHA bit settings.
For details on the transfer format, see section 16.4.4, Transfer Format. The polarity of the SSL
input signal depends on the setting of the SSL0P bit in the slave select polarity register (SSLP).

(b)
SH7262 Group, SH7264 Group
Terminating Serial Transfer
Irrespective of the CPHA bit in the command register 0 (SPCMD0), this module terminates the
serial transfer after detecting an RSPCK edge corresponding to the final sampling timing. When
the receive buffer has an enough space for receive data, this module copies received data from the
shift register to the receive buffer of the data register (SPDR) upon termination of the serial
transfer. Irrespective of the value of the SPRF bit, this module changes the status of the shift
register to "empty" upon termination of the serial transfer. If this module detects an SSL input
signal negation from the beginning of serial transfer to the end of serial transfer, a mode fault error
occurs (see section 16.4.6, Error Detection).
The final sampling timing changes depending on the bit length of the transfer data. In slave mode,
the data length depends on the settings in bits SPB3 to SPB0 bits in SPCMD0. The polarity of the
SSL input signal depends on the setting in the SSL0P bit in the slave select polarity register
(SSLP). For details on the transfer format, see section 16.4.4, Transfer Format.
(c)
Notes on Slave Operations
If the CPHA bit in the command register 0(SPCMD0) is 0, this module starts serial transfers when
it detects the assertion edge for an SSL input signal. In the type of configuration shown in figure
16.4 as an example, if this module is used in single-slave mode, the SSL signal is always fixed at
active state. Therefore, when the CPHA bit is set to 0, this module cannot correctly start a serial
transfer. To correctly execute send/receive operation in a configuration in which the SSL input
signal is fixed at active state, the CPHA bit should be set to 1. When it is necessary to set the
CPHA bit to 0, the SSL input signal should not be fixed.
(d)
Burst Transfer
If the CPHA bit in the command register 0 (SPCMD0) is 1, continuous serial transfer (burst
transfer) can be executed while retaining the assertion state for the SSL input signal. If the CPHA
bit is 1, the period from the first RSPCK edge to the sampling timing for the reception of the final
bit in an SSL signal active state corresponds to a serial transfer period. Even when the SSL input
signal remains at the active level, this module can accommodate burst transfers because it can
detect the start of access.
If the CPHA bit is 0, for the reason given in section 16.4.8 (2) (c), Notes on Slave Operations,
second and subsequent serial transfers during the burst transfer cannot be executed correctly.

16.4.10 Loopback Mode
When 1 is written to the SPLP bit in the pin control register (SPPCR), this module shuts off the
path between the MISO pin and the shift register, and between the MOSI pin and the shift register,
and connects the input path and the output path (reversed) of the shift register. This is called
loopback mode. When a serial transfer is executed in loopback mode, the transmit data becomes
the received data. Figure 16.24 shows the configuration of the shift register input/output paths for
the case where this module in master mode is set in loopback mode.

Section 17 I2C Bus Interface 3
Section 17 I2C Bus Interface 3
The I2C bus interface 3 conforms to and provides a subset of the Philips I2C (Inter-IC) bus
interface functions. However, the configuration of the registers that control the I2C bus differs
partly from the Philips register configuration.
The I2C bus interface 3 has three channels.
17.1
Features
Selection of I2C format or clocked synchronous serial format
Continuous transmission/reception
Since the shift register, transmit data register, and receive data register are independent from
each other, the continuous transmission/reception can be performed.
I2C bus format:
Start and stop conditions generated automatically in master mode
Selection of acknowledge output levels when receiving
Automatic loading of acknowledge bit when transmitting
Bit synchronization function
In master mode, the state of SCL is monitored per bit, and the timing is synchronized
automatically. If transmission/reception is not yet possible, set the SCL to low until
preparations are completed.
Six interrupt sources
Transmit data empty (including slave-address match), transmit end, receive data full (including
slave-address match), arbitration lost, NACK detection, and stop condition detection
The direct memory access controller can be activated by a transmit-data-empty request or
receive-data-full request to transfer data.
Direct bus drive
Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive
function is selected.
Clocked synchronous serial format:
Four interrupt sources
Transmit-data-empty, transmit-end, receive-data-full, and overrun error
The direct memory access controller can be activated by a transmit-data-empty request or
receive-data-full request to transfer data.

In master mode with the I2C bus format, when
arbitration is lost, MST and TRS are both reset by

Modification of the TRS bit should be made between
transfer frames.
When seven bits after the start condition is issued in
slave receive mode match the slave address set to
SAR and the 8th bit is set to 1, TRS is automatically
set to 1. If an overrun error occurs in master receive
mode with the clocked synchronous serial format, MST
is cleared and the mode changes to slave receive

Operating modes are described below according to
MST and TRS combination. When clocked

described below.
1. Set the ICE bit in ICCR1 to 1. Also, set bits CKS[3:0] in ICCR1. (Initial setting)
2. Read the BBSY flag in ICCR2 to confirm that the bus is released. Set the MST and TRS bits in
ICCR1 to select master transmit mode. Then, write 1 to BBSY and 0 to SCP. (Start condition
issued) This generates the start condition.
3. After confirming that TDRE in ICSR has been set, write the transmit data (the first byte data
show the slave address and R/W) to ICDRT. At this time, TDRE is automatically cleared to 0,
and data is transferred from ICDRT to ICDRS. TDRE is set again.
4. When transmission of one byte data is completed while TDRE is 1, TEND in ICSR is set to 1
at the rise of the 9th transmit clock pulse. Read the ACKBR bit in ICIER, and confirm that the
slave device has been selected. Then, write second byte data to ICDRT. When ACKBR is 1,
the slave device has not been acknowledged, so issue the stop condition. To issue the stop
condition, write 0 to BBSY and SCP. SCL is fixed low until the transmit data is prepared or
the stop condition is issued.
5. The transmit data after the second byte is written to ICDRT every time TDRE is set.
6. Write the number of bytes to be transmitted to ICDRT. Wait until TEND is set (the end of last
byte data transmission) while TDRE is 1, or wait for NACK (NACKF in ICSR = 1) from the
receive device while ACKE in ICIER is 1. Then, issue the stop condition to clear TEND or
NACKF.
7. When the STOP bit in ICSR is set to 1, the operation returns to the slave receive mode.

Section 17 I2C Bus Interface 3
Master Receive Operation
In master receive mode, the master device outputs the receive clock, receives data from the slave
device, and returns an acknowledge signal. For master receive mode operation timing, refer to
figures 17.7 and 17.8. The reception procedure and operations in master receive mode are shown
below.
1. Clear the TEND bit in ICSR to 0, then clear the TRS bit in ICCR1 to 0 to switch from master
transmit mode to master receive mode. Then, clear the TDRE bit to 0.
2. When ICDRR is read (dummy data read), reception is started, and the receive clock is output,
and data received, in synchronization with the internal clock. The master device outputs the
level specified by ACKBT in ICIER to SDA, at the 9th receive clock pulse.
3. After the reception of first frame data is completed, the RDRF bit in ICSR is set to 1 at the rise
of 9th receive clock pulse. At this time, the receive data is read by reading ICDRR, and RDRF
is cleared to 0.
4. The continuous reception is performed by reading ICDRR every time RDRF is set. If 8th
receive clock pulse falls after reading ICDRR by the other processing while RDRF is 1, SCL is
fixed low until ICDRR is read.
5. If next frame is the last receive data, set the RCVD bit in ICCR1 to 1 before reading ICDRR.
This enables the issuance of the stop condition after the next reception.
6. When the RDRF bit is set to 1 at rise of the 9th receive clock pulse, issue the stage condition.
7. When the STOP bit in ICSR is set to 1, read ICDRR. Then clear the RCVD bit to 0.
8. The operation returns to the slave receive mode.
Note: If only one byte is received, read ICDRR (dummy-read) after the RCVD bit in ICCR1 is
set.

Slave Transmit Operation
In slave transmit mode, the slave device outputs the transmit data, while the master device outputs
the receive clock and returns an acknowledge signal. For slave transmit mode operation timing,
refer to figures 17.9 and 17.10.
The transmission procedure and operations in slave transmit mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and
TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches.
2. When the slave address matches in the first frame following detection of the start condition,
the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th
clock pulse. At this time, if the 8th bit data (R/W) is 1, the TRS bit in ICCR1 and the TDRE bit
in ICSR are set to 1, and the mode changes to slave transmit mode automatically. The
continuous transmission is performed by writing transmit data to ICDRT every time TDRE is
set.
3. If TDRE is set after writing last transmit data to ICDRT, wait until TEND in ICSR is set to 1,
with TDRE = 1. When TEND is set, clear TEND.
4. Clear TRS for the end processing, and read ICDRR (dummy read). SCL is opened.
5. Clear TDRE.

Slave Receive Operation
In slave receive mode, the master device outputs the transmit clock and transmit data, and the
slave device returns an acknowledge signal. For slave receive mode operation timing, refer to
figures 17.11 and 17.12. The reception procedure and operations in slave receive mode are
described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and
TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches.
2. When the slave address matches in the first frame following detection of the start condition,
the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th
clock pulse. At the same time, RDRF in ICSR is set to read ICDRR (dummy read). (Since the
read data show the slave address and R/W, it is not used.)
3. Read ICDRR every time RDRF is set. If 8th receive clock pulse falls while RDRF is 1, SCL is
fixed low until ICDRR is read. The change of the acknowledge before reading ICDRR, to be
returned to the master device, is reflected to the next transmit frame.
4. The last byte data is read by reading ICDRR.

Clocked Synchronous Serial Format
This module can be operated with the clocked synchronous serial format, by setting the FS bit in
SAR to 1. When the MST bit in ICCR1 is 1, the transfer clock output from SCL is selected. When
MST is 0, the external clock input is selected.
(1)
Data Transfer Format
Figure 17.13 shows the clocked synchronous serial transfer format.
The transfer data is output from the fall to the fall of the SCL clock, and the data at the rising edge
of the SCL clock is guaranteed. The MLS bit in ICMR sets the order of data transfer, in either the
MSB first or LSB first. The output level of SDA can be changed during the transfer wait, by the
SDAO bit in ICCR2.

Transmit Operation
In transmit mode, transmit data is output from SDA, in synchronization with the fall of the transfer
clock. The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For
transmit mode operation timing, refer to figure 17.14. The transmission procedure and operations
in transmit mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set the MST and CKS[3:0] bits in ICCR1. (Initial setting)
2. Set the TRS bit in ICCR1 to select the transmit mode. Then, TDRE in ICSR is set.
3. Confirm that TDRE has been set. Then, write the transmit data to ICDRT. The data is
transferred from ICDRT to ICDRS, and TDRE is set automatically. The continuous
transmission is performed by writing data to ICDRT every time TDRE is set. When changing
from transmit mode to receive mode, clear TRS while TDRE is 1.

Receive Operation
In receive mode, data is latched at the rise of the transfer clock. The transfer clock is output when
MST in ICCR1 is 1, and is input when MST is 0. For receive mode operation timing, refer to
figure 17.15. The reception procedure and operations in receive mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. When the transfer clock is output, set MST to 1 to start outputting the receive clock.
3. When the receive operation is completed, data is transferred from ICDRS to ICDRR and
RDRF in ICSR is set. When MST = 1, the next byte can be received, so the clock is
continually output. The continuous reception is performed by reading ICDRR every time
RDRF is set. When the 8th clock is risen while RDRF is 1, the overrun is detected and
AL/OVE in ICSR is set. At this time, the previous reception data is retained in ICDRR.
4. To stop receiving when MST = 1, set RCVD in ICCR1 to 1, then read ICDRR. Then, SCL is
fixed high after receiving the next byte data.
Notes: Follow the steps below to receive only one byte with MST = 1 specified. See figure 17.16
for the operation timing.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. Set MST = 1 while the RCVD bit in ICCR1 is 0. This causes the receive clock to be
output.
3. Check if the BC2 bit in ICMR is set to 1 and then set the RCVD bit in ICCR1 to 1.
This causes the SCL to be fixed to the high level after outputting one byte of the
receive clock.

Noise Filter
The logic levels at the SCL and SDA pins are routed through noise filters before being latched
internally. Figure 17.17 shows a block diagram of the noise filter circuit.
The noise filter consists of three cascaded latches and a match detector. The SCL (or SDA) input
signal is sampled on the peripheral clock. When NF2CYC is set to 0, this signal is not passed
forward to the next circuit unless the outputs of both latches agree. When NF2CYC is set to 1, this
signal is not passed forward to the next circuit unless the outputs of three latches agree. If they do
not agree, the previous value is held.

Interrupt Requests
There are six interrupt requests in this module; transmit data empty, transmit end, receive data full,
NACK detection, STOP recognition, and arbitration lost/overrun error. Table 17.4 shows the
contents of each interrupt request.

When the interrupt condition described in table 17.4 is 1, the CPU executes an interrupt exception
handling. Note that a TXI or RXI interrupt can activate the direct memory access controller if the
setting for direct memory access controller activation has been made. In such a case, an interrupt
request is not sent to the CPU. Interrupt sources should be cleared in the exception handling. The
TDRE and TEND bits are automatically cleared to 0 by writing the transmit data to ICDRT. The
RDRF bit is automatically cleared to 0 by reading ICDRR. The TDRE bit is set to 1 again at the
same time when the transmit data is written to ICDRT. Therefore, when the TDRE bit is cleared to
0, then an excessive data of one byte may be transmitted.

Bit Synchronous Circuit
In master mode, this module has a possibility that high level period may be short in the two states
described below.
When SCL is driven to low by the slave device
When the rising speed of SCL is lowered by the load of the SCL line (load capacitance or pullup resistance)
Therefore, it monitors SCL and communicates by bit with synchronization.
Figure 17.22 shows the timing of the bit synchronous circuit and table 17.5 shows the time when
the SCL output changes from low to Hi-Z then SCL is monitored.

Usage Notes
17.7.1
Note on Setting for Multi-Master Operation
SH7262 Group, SH7264 Group
In multi-master operation, when the transfer rate setting for this module (ICCR1.CKS[3:0]) makes
this LSI slower than the other masters, pulse cycles with an unexpected length will infrequently be
output on SCL.
Be sure to specify a transfer rate that is at least 1/1.8 of the fastest transfer rate among the other
masters.
17.7.2
Note on Master Receive Mode
Reading ICDRR around the falling edge of the 8th clock might fail to fetch the receive data.
In addition, when RCVD is set to 1 around the falling edge of the 8th clock and the receive buffer
full, a stop condition may not be issued.
Use either 1 or 2 below as a measure against the situations above.
1. In master receive mode, read ICDRR before the rising edge of the 8th clock.
2. In master receive mode, set the RCVD bit to 1 so that transfer proceeds in byte units.
17.7.3
Note on Setting ACKBT in Master Receive Mode
In master receive mode operation, set ACKBT before the falling edge of the 8th SCL cycle of the
last data being continuously transferred. Not doing so can lead to an overrun for the slave
transmission device.

17.7.4
Section 17 I2C Bus Interface 3
Note on the States of Bits MST and TRN when Arbitration is Lost
When sequential bit-manipulation instructions are used to set the MST and TRS bits to select
master transmission in multi-master operation, a conflicting situation where AL in ICSR = 1 but
the mode is master transmit mode (MST = 1 and TRS = 1) may arise; this depends on the timing
of the loss of arbitration when the bit manipulation instruction for TRS is executed.
This can be avoided in either of the following ways.
In multi-master operation, use the MOV instruction to set the MST and TRS bits.
When arbitration is lost, check whether the MST and TRS bits are 0. If the MST and TRS bits
have been set to a value other than 0, clear the bits to 0.
17.7.5
Note on I2C-bus Interface Master Receive Mode
After a master receive operation is completed, confirm the falling edge of the ninth clock cycle of
the SCL signal and generate a stop condition or regenerate a start condition.
17.7.6
Note on IICRST and BBSY bits
When 1 is written to IICRST in ICCR2, this LSI release SCL and SDA pins. Then, if the SDA
level changes from low to high under the condition of SCL = high, BBSY in ICCR2 is cleared to 0
assuming that the stop condition has been issued.
17.7.7
Note on Issuance of Stop Conditions in Master Transmit Mode while ACKE = 1
When a stop condition is issued in master transmit mode while the ACKE bit in the I2C bus
interrupt enable register (ICIER) is 1, the stop condition may not be normally output depending on
the issued timing. To avoid this, recognize the falling edge of the ninth clock before issuance of
the stop condition.
The falling edge of the ninth clock can be recognized by checking the SCLO bit in the I2C control
register 2 (ICCR2).

Section 18 Serial Sound Interface
The serial sound interface is a module designed to send or receive audio data interface with
various devices offering I2S bus compatibility. It also provides additional modes for other common
formats, as well as support for multi-channel mode.
18.1
Features
Number of channels: Four channels
Operating mode: Non-compressed mode
The non-compressed mode supports serial audio streams divided by channels.
Serves as both a transmitter and a receiver
Channel 0 supports full-duplex communications.
Capable of using serial bus format
Asynchronous transfer takes place between the data buffer and the shift register.
It is possible to select a value as the dividing ratio for the clock used by the serial bus interface.
It is possible to control data transmission or reception with DMA transfer and interrupt
requests.
Selects the oversampling clock input from among the following pins:
AUDIO_CLK (1 to 25 MHz)
AUDIO_X1, AUDIO_X2 (when connecting a crystal resonator: 10 to 25 MHz, when used to
input external clock: 1 to 25 MHz)
Includes 8-stage FIFO buffers in transmitter and receiver

R/(W)* Transmit Underflow Error Interrupt Status Flag
This status flag indicates that transmit data was
supplied at a lower rate than was required.
This bit is set to 1 regardless of the value of the TUIEN
bit and can be cleared by writing 0 to this bit.
If TUIRQ = 1 and TUIEN = 1, an interrupt occurs.
If TUIRQ = 1, SSITDR did not have data written to it
before it was required for transmission. This will lead to
the same data being transmitted once more and a
potential corruption of multi-channel data. As a result,
this module will output erroneous data.
Note: When an underflow error occurs, the current data
in the data buffer of this module is transmitted
until the next data is written.

If RUIRQ = 1 and RUIEN = 1, an interrupt occurs.
If RUIRQ = 1, SSIFRDR was read while the receive
FIFO is empty (RDC = H'0).This can cause invalid
receive data to be stored, which may lead to corruption

If ROIRQ = 1 and ROIEN = 1, an interrupt occurs.
If ROIRQ = 1, SSIRDR was not read before there was
new unread data written to it. This will lead to the loss
of data and a potential corruption of multi-channel data.
Note: When an overflow error occurs, the current data
in the data buffer of this module is overwritten by
the next incoming data from the SSI interface.

Transmit Data Register (SSITDR)
SSITDR is a 32-bit register that stores data to be transmitted. The data for transmission to be
stored to SSITDR is automatically transferred from the transmit FIFO data register.
Data written to this register is transferred to the shift register upon transmission request. If the data
word length is less than 32 bits, the alignment is determined by the setting of the PDTA control bit
in SSICR.
The CPU cannot read or write data from/to SSITDR.

Note: 1. Since SSIFRDR is an 8-stage FIFO register,
the amount of data that can be read from it
while RDF = 1 is the set receive trigger number
of bytes at maximum.
Continuing to read data from SSIFRDR after
reading all the data will result in undefined data
to be read. The number of data bytes in
SSIFRDR is indicated in the RDC bits in
SSIFSR.
Note:
*
The bit can be read or written to. Writing 0 initializes the bit, but writing 1 is ignored.

Transmit FIFO Data Register (SSIFTDR)
SSIFTDR is a FIFO register consisting of eight stages of 32-bit registers for storing data to be
serially transmitted. On detecting that the transmit data register (SSITDR) is empty, this module
transfers the data for transmission written to SSIFTDR to SSITDR to start serial transmission,
which can continue until SSIFTDR becomes empty. SSIFTDR can be written to by the CPU at
any time.
Note that when SSIFTDR is full of data (32 bytes), the next data cannot be written to it. If writing
is attempted, it will be ignored and an overflow occurs.

Receive FIFO Data Register (SSIFRDR)
SSIFRDR is a FIFO register consisting of eight stages of 32-bit registers for storing serially
received data. When four bytes of data have been received, this module transfers the received data
in the receive data register (SSIRDR) to SSIFRDR to complete reception operation. Reception can
continue until 32 bytes of data have been stored to SSIFRDR. SSIFRDR can be read by the CPU
but cannot be written to. Note that when SSIFRDR is read when it stores no received data,
undefined values will be read and a receive underflow occurs.
After SSIFRDR becomes full of received data, the data received thereafter will be lost and a
receive overflow occurs.

Section 18 Serial Sound Interface
Non-Compressed Modes
The non-compressed modes support all serial audio streams split into channels. It supports I2S
compatible format as well as many more variants on these modes.
(1)
Slave Receiver
This mode allows the module to receive serial data from another device. The clock and word
select signal used for the serial data stream is also supplied from an external device. If these
signals do not conform to the format specified in the configuration fields of this module, operation
is not guaranteed.
(2)
Slave Transmitter
This mode allows the module to transmit serial data to another device. The clock and word select
signal used for the serial data stream is also supplied from an external device. If these signals do
not conform to the format specified in the configuration fields of this module, operation is not
guaranteed.
(3)
Slave Transceiver
This mode allows serial data transmission and reception between this module and another device.
The clock and word select signal used for the serial data stream is also supplied from an external
device. If these signals do not conform to the format specified in the configuration fields of this
module, operation is not guaranteed.
(4)
Master Receiver
This mode allows the module to receive serial data from another device. The clock and word
select signals are internally derived from the oversampling clock. The format of these signals is
defined in the configuration fields of this module. If the incoming data does not follow the
configured format, operation is not guaranteed.
(5)
Master Transmitter
This mode allows the module to transmit serial data to another device. The clock and word select
signals are internally derived from the oversampling clock. The format of these signals is defined
in the configuration fields of this module.

Operating Setting Related to Word Length
All bits related to the SSICR's word length are valid in non-compressed modes. There are many
configurations this module supports, but the formats described below are I2S compatible, MSBfirst left-aligned, and MSB-first right-aligned.
I2S Compatible Format
Figures 18.3 and 18.4 demonstrate the supported I2S compatible format both without and with
padding. Padding occurs when the data word length is smaller than the system word length.

Multi-channel Formats
Some devices extend the definition of the specification by I2S bus and allow more than 2 channels
to be transferred within two system words.
This module supports the transfer of 4, 6, and 8 channels by using the CHNL, SWL and DWL bits
only when the system word length (SWL) is greater than or equal to the data word length (DWL)
multiplied by channels (CHNL).
Table 18.4 shows the number of padding bits for each of the valid setting. If setting is not valid,
"" is indicated instead of a number.

When this module acts as a transmitter, each word written to SSITDR is transmitted to the serial
audio bus in the order they are written. When this module acts as a receiver, each word received
by the serial audio bus is read in the order received from the SSIRDR register.
Figures 18.7 to 18.9 show how the data on 4, 6, and 8 channels are transferred to the serial audio
bus. Note that there are no padding bits in the first example, the second example is left-aligned and
the third is right-aligned. The other conditions in these examples have been selected arbitrarily.

This mode is entered after the module is released from reset. All required configuration fields in
the control register should be defined in this mode, before this module is enabled by setting the
TEN and REN bits.
Setting the TEN and REN bits causes the module to enter the module enabled mode.

Transmit Operation
Transmission can be controlled either by DMA transfer or interrupt.
DMA control is preferred to reduce the processor load. In DMA control mode, the processor will
only receive interrupts if there is an underflow or overflow of data or if the DMA transfer has been
completed.
The alternative method is using the interrupts that this module generates to supply data as
required.
When disabling this module, the clock* must be kept supplied to this module until the IIRQ bit
indicates that the module is in the idle state.
Figure 18.20 shows the transmit operation in DMA control mode, and figure 18.21 shows the
transmit operation in interrupt control mode.

Section 18 Serial Sound Interface
SH7262 Group, SH7264 Group
When an underflow or overflow error condition has matched, this module can be recovered to the
status before underflow or overflow condition match by using the TCHNO [1:0] and TSWNO bits
in transmission and the RCHNO[1:0] and RSWNO bits in reception. When an underflow or
overflow occurs, the host can read the channel number and system word number to determine
what point the serial audio stream has reached. In the transmitter case, the host can skip forward
through the data it wants to transmit until it finds the sample data that matches what this module is
expecting to transmit next, and so resynchronize with the audio data stream. In the receiver case
the host CPU can store null data to make the number of receive data items consistent until it is
ready to store the sample data that this module is indicating will be received next, and so
resynchronize with the audio data stream.
18.4.6
Serial Bit Clock Control
This function is used to control and select which clock is used for the serial bus interface.
If the serial clock direction is set to input (SCKD = 0), this module is in clock slave mode and the
shift register uses the bit clock that was input to the SSISCK pin.
If the serial clock direction is set to output (SCKD = 1), this module is in clock master mode, and
the shift register uses the oversampling clock or a divided oversampling clock as the bit clock. The
oversampling clock is divided by the ratio specified by the serial oversampling clock division ratio
bits (CKDV) in SSICR for use as the bit clock by the shift register.
In either case the module pin, SSISCK, is the same as the bit clock.

Usage Notes
18.5.1
Limitations from Underflow or Overflow during DMA Operation
If an underflow or overflow occurs while the DMA is in operation, the module should be restarted.
The transmit and receive buffers in the SSIF consists of 32-bit registers that share the L and R
channels. Therefore, data to be transmitted and received at the L channel may sometimes be
transmitted and received at the R channel if an underflow or overflow occurs, for example, under
the following condition: the control register (SSICR) has a 32-bit setting for both data word length
(DWL2 to DWL0) and system word length (SWL2 to SWL0).
If an error occurrence is confirmed with four types of error interrupts (transmit underflow,
transmit overflow, receive underflow, and receive overflow) or the corresponding error status flag
(the bits TUIRQ, TOIRQ, RUIRQ, and ROIRQ in SSISR), write 0 to the TEN or REN bit in
SSICR to disable DMA transfer requests in this module, thus stopping the operation. (In this case,
the direct memory access controller setting should also be stopped.) After this, for receive
operation write 0 to the error status flag bit to clear the error status, make settings to the direct
memory access controller again, and restart the transfer. For transmit operation perform a software
reset, then start again from the start sequence.
18.5.2
Note on Changing Mode from Master Transceiver to Master Receiver
If a transmit underflow occurs in master transceiver mode and the TEN bit in SSICR is set to 0 in
order to disable transmit operation, SSIWS output is broken. In order to receive seamlessly after
changing mode to master receiver mode, write dummy data to SSITDR to suppress transmit
underflow.

FIFO
Overview
The transmit and receive FIFOs of this module have the following features.
16-stage 32-bit FIFOs for transmission and reception
One FIFO buffer stage is used regardless of the access size. (One-stage 32-bit FIFO access
cannot be divided into multiple accesses.)
(2)
Transfer Request
The following FIFO transfer requests can be issued to the CPU or direct memory access
controller.
Transmit request: TDREQ (transmit FIFO transfer request)
Receive request: RDREQ (receive FIFO transfer request)
The conditions to issue the transmit/receive FIFO transfer requests can be specified individually.
The transmit request condition is specified with the TFWM2 to TFWM0 bits in SIFCTR, and the
receive FIFO transfer request is specified with the RFWM2 to RFWM0 bits in SIFCTR. Tables
19.8 and 19.9 summarize the conditions specified by SIFCTR.

The number of stages of the FIFO is sixteen. Accordingly, an overflow error or underflow error
occurs if data area or empty area exceeds sixteen FIFO stages. The transfer request is canceled
when the above condition is not satisfied even if the FIFO is not empty or full.
(3)
Number of FIFOs
The usage state of the transmit FIFO and receive FIFO are indicated by the TFUA and FRUA bits
in the FIFO control register as below:
Transmit FIFO: The number of empty FIFO stages is indicated by the TFUA4 to TFUA0 bits
in SIFCTR.
Receive FIFO: The number of valid data stages is indicated by the RFUA4 to RFUA0 bits in
SIFCTR.
The above register contents indicate the possible data numbers that can be transferred by the CPU
or direct memory access controller.

Description
Whether the interrupt is issued or not by the request is determined by the SIIER settings. If an
interrupt request is generated when the corresponding bit in SIIER is set to 1, this module issues
the interrupt.

SH7262 Group, SH7264 Group
Regarding Transmit and Receive Classification
The transmit request and receive request are signals indicating the state; after being set, if the state
of the transmit/receive FIFO change, they are automatically cleared by this module.
When the DMA transfer is used, the signal is cleared to 0 by the direct memory access controller.
If the setting condition is still satisfied after the access using the direct memory access controller,
it is set to 1 again.
(3)
Processing when Errors Occur
On occurrence of each of the errors indicated as a status in SISTR, this module performs the
following operations.
Transmit FIFO underflow (TFUDF)
The immediately preceding transmit data is again transmitted.
Transmit FIFO overflow (TFOVF)
The contents of the transmit FIFO are protected, and the write operation causing the overflow
is ignored.
Receive FIFO overflow (RFOVF)
Data causing the overflow is discarded and lost.
Receive FIFO underflow (RFUDF)
The read value is undefined.
FS error (FSERR)
The internal counter is reset according to the sync signal in which an error occurs.

Summary
20.1.1
Overview
This document primarily describes the programming interface for the controller area network
(Renesas CAN Time Trigger Level 1) module. It serves to facilitate the hardware/software
interface so that engineers involved in this module implementation can ensure the design is
successful.
Deep standby mode can be canceled by change on CRxn (PJ3, PJ1) pin. For details, refer to
section 33, Power-Down Modes.
20.1.2
Scope
The CAN Data Link Controller function is not described in this document. It is the responsibility
of the reader to investigate the CAN Specification Document (see references). The interfaces from
the CAN Controller are described, in so far as they pertain to the connection with the User
Interface.
The programming model is described in some detail. It is not the intention of this document to
describe the implementation of the programming interface, but to simply present the interface to
the underlying CAN functionality.
The document places no constraints upon the implementation of this module in terms of process,
packaging or power supply criteria. These issues are resolved where appropriate in
implementation specifications.
20.1.3
Audience
In particular this document provides the design reference for software authors who are responsible
for creating a CAN application using this module.
In the creation of this module user interface LSI engineers must use this document to understand
the hardware requirements.

Important: LongWord (32-bit) accesses are converted into two consecutive word (16-bit)
accesses by the bus interface.
Micro Processor Interface (MPI)
The MPI allows communication between the Renesas CPU and this module’s
registers/mailboxes to control the memory interface. It also contains the Wakeup Control logic
that detects the CAN bus activities and notifies the MPI and the other parts of this module so
that this module can automatically exit the Sleep mode.
It contains registers such as MCR, IRR, GSR and IMR.
Mailbox
The Mailboxes consists of RAM configured as message buffers and registers. There are 32
Mailboxes, and each mailbox has the following information.
CAN message control (identifier, rtr, ide,etc)
CAN message data (for CAN Data frames)
Local Acceptance Filter Mask for reception
CAN message control (dlc)
Time Stamp for message reception/transmission
3-bit wide Mailbox Configuration, Disable Automatic Re-Transmission bit, AutoTransmission for Remote Request bit, New Message Control bit
Tx-Trigger Time
Mailbox Control
The Mailbox Control handles the following functions.
For received messages, compare the IDs and generate appropriate RAM addresses/data to
store messages from the CAN Interface into the Mailbox and set/clear appropriate registers
accordingly.
To transmit event-triggered messages, run the internal arbitration to pick the correct
priority message, and load the message from the Mailbox into the Tx-buffer of the CAN
Interface and set/clear appropriate registers accordingly. In the case of time-triggered
transmission, compare match of Tx-Trigger time invoke loading the messages.
Arbitrates Mailbox accesses between the CPU and the Mailbox Control.
Contains registers such as TXPR, TXCR, TXACK, ABACK, RXPR, RFPR, UMSR and
MBIMR.

Timer
The Timer function is the functional entity, which provides this module with support for
transmitting messages at a specific time frame and recording the result.
The Timer is a 16-bit free running up counter which can be controlled by the CPU. It provides
one 16-bit Compare Match Register to compare with Local Time and two 16-bit ones to
compare with Cycle Time. The Compare Match Registers can generate interrupt signals and
clear the Counter.
The clock period of this Timer offers a wide selection derived from the system clock or can be
programmed to be incremented with one nominal bit timing of CAN Bus.
Contains registers such as TCNTR, TTCR0, CMAX_TEW, RFTROFF, TSR, CCR, CYCTR,
RFMK, TCMR0, TCMR1, TCMR2 and TTTSEL.
CAN Interface
This block conforms to the requirements for a CAN Bus Data Link Controller which is
specified in Ref. [2, 4]. It fulfils all the functions of a standard DLC as specified by the OSI 7
Layer Reference model. This functional entity also provides the registers and the logic which
are specific to a given CAN bus, which includes the Receive Error Counter, Transmit Error
Counter, the Bit Configuration Registers and various useful Test Modes. This block also
contains functional entities to hold the data received and the data to be transmitted for the
CAN Data Link Controller.

Notes: 1. All bits shadowed in grey are reserved and must be written LOW. The value returned
by a read may not always be ‘0’ and should not be relied upon.
2. ATX and DART are not supported by Mailbox-0, and the MBC setting of Mailbox-0 is
limited.
3. ID Reorder (MCR15) can change the order of STDID, RTR, IDE and EXTID of both

STDID[10:0]: These bits set the identifier (standard identifier) of data frames and remote frames.
EXTID[17:0]: These bits set the identifier (extended identifier) of data frames and remote frames.
RTR (Remote Transmission Request bit): Used to distinguish between data frames and remote
frames. This bit is overwritten by received CAN Frames depending on Data Frames or Remote
Frames.
Important: Please note that, when ATX bit is set with the setting MBC = 001(bin), the RTR bit
will never be set. When a Remote Frame is received, the CPU can be notified by the
corresponding RFPR set or IRR[2] (Remote Frame Receive Interrupt), however, as this module
needs to transmit the current message as a Data Frame, the RTR bit remains unchanged.
Important: In order to support automatic answer to remote frame when MBC = 001 (bin) is used
and ATX = 1 the RTR flag must be programmed to zero to allow data frame to be transmitted.
Note: when a Mailbox is configured to send a remote frame request the DLC used for
transmission is the one stored into the Mailbox.

NMC (New Message Control): When this bit is set to '0', the Mailbox of which the RXPR or
RFPR bit is already set does not store the new message but maintains the old one and sets the
UMSR correspondent bit. When this bit is set to '1', the Mailbox of which the RXPR or RFPR bit
is already set overwrites with the new message and sets the UMSR correspondent bit.
Important: Please note that if a remote frame is overwritten with a data frame or vice versa could
be that both RXPR and RFPR flags (together with UMSR) are set for the same Mailbox. In this
case the RTR bit within the Mailbox Control Field should be relied upon.
Important: Please note that when the Time Triggered mode is used NMC needs to be set to ‘1’
for Mailbox 31 to allow synchronization with all incoming reference messages even when
RXPR[31] is not cleared.

ATX (Automatic Transmission of Data Frame): When this bit is set to ‘1’ and a Remote Frame
is received into the Mailbox DLC is stored. Then, a Data Frame is transmitted from the same
Mailbox using the current contents of the message data and updated DLC by setting the
corresponding TXPR automatically. The scheduling of transmission is still governed by ID
priority or Mailbox priority as configured with the Message Transmission Priority control bit
(MCR.2). In order to use this function, MBC[2:0] needs to be programmed to be ‘001’ (Bin).
When a transmission is performed by this function, the DLC (Data Length Code) to be used is the
one that has been received. Application needs to guarantee that the DLC of the remote frame
correspond to the DLC of the data frame requested.
Important: When ATX is used and MBC = 001 (Bin) the filter for the IDE bit cannot be used
since ID of remote frame has to be exactly the same as that of data frame as the reply message.
Important: Please note that, when this function is used, the RTR bit will never be set despite
receiving a Remote Frame. When a Remote Frame is received, the CPU will be notified by the
corresponding RFPR set, however, as this module needs to transmit the current message as a Data
Frame, the RTR bit remains unchanged.
Important: Please note that in case of overrun condition (UMSR flag set when the Mailbox has
its NMC = 0) the message received is discarded. In case a remote frame is causing overrun into a
Mailbox configured with ATX = 1, the transmission of the corresponding data frame may be
triggered only if the related PFPR flag is cleared by the CPU when the UMSR flag is set. In such
case PFPR flag would get set again.

DART (Disable Automatic Re-Transmission): When this bit is set, it disables the automatic retransmission of a message in the event of an error on the CAN bus or an arbitration lost on the
CAN bus. In effect, when this function is used, the corresponding TXCR bit is automatically set at
the start of transmission. When this bit is set to '0', this module tries to transmit the message as
many times as required until it is successfully transmitted or it is cancelled by the TXCR.

MBC[2:0] (Mailbox Configuration): These bits configure the nature of each Mailbox as follows.
When MBC = 111 (Bin), the Mailbox is inactive, i.e., it does not receive or transmit a message
regardless of TXPR or other settings. The MBC = '110', '101' and '100' settings are prohibited.
When the MBC is set to any other value, the LAFM field becomes available. Please don't set
TXPR when MBC is set as reception as there is no hardware protection, and TXPR will remain
set. MBC[1] of Mailbox-0 is fixed to "1" by hardware. This is to ensure that MB0 cannot be
configured to transmit Messages.

Local Acceptance Filter Mask (LAFM)
This area is used as Local Acceptance Filter Mask (LAFM) for receive boxes.
LAFM: When MBC is set to 001, 010, 011(Bin), this field is used as LAFM Field. It allows a
Mailbox to accept more than one identifier. The LAFM is comprised of two 16-bit read/write
areas as follows.

If a bit is set in the LAFM, then the corresponding bit of a received CAN identifier is ignored
when this module searches a Mailbox with the matching CAN identifier. If the bit is cleared, then
the corresponding bit of a received CAN identifier must match to the STDID/IDE/EXTID set in
the mailbox to be stored. The structure of the LAFM is same as the message control in a Mailbox.
If this function is not required, it must be filled with '0'.
Important: This module starts to find a matching identifier from Mailbox-31 down to Mailbox-0.
As soon as this module finds one matching, it stops the search. The message will be stored or not
depending on the NMC and RXPR/RFPR flags. This means that, even using LAFM, a received
message can only be stored into 1 Mailbox.

Message Data Fields
Storage for the CAN message data that is transmitted or received. MSG_DATA[0] corresponds to
the first data byte that is transmitted or received. The bit order on the CAN bus is bit 7 through to
bit 0.
When CMAX!= 3'b111/MBC[30] = 3'b000 and TXPR[30] is set, Mailbox-30 is configured as
transmission of time reference. Its DLC must be greater than 0 and its RTR must be zero (as
specified for TTCAN Level 1) so that the Cycle_count (CCR register) is embedded in the first
byte of the data field instead of MSG_DATA_0[5:0] when this Mailbox starts transmission. This
function shall be used when this module is enabled to work in TTCAN mode to perform a
Potential Time Master role to send the Time reference message. MSG_DATA_0[7:6] is still
transmitted as stored in the Mailbox. User can set MSG_DATA_0[7] when a Next_is_Gap needs
to be transmitted.

Please note that the CCR value is only embedded on the frame transmitted but not stored back into
Mailbox 30.
When CMAX!= 3'b111, MBC[31] = 3'b011 and TXPR[31] is cleared, Mailbox-31 is configured
as reception of time reference. When a valid reference message is received (DLC > 0) this module
performs internal synchronisation (modifying its RFMK and basic cycle CCR).

Message Receive: For received messages of Mailbox-15 to 0, Timestamp always captures the
CYCTR (Cycle Time Register) value or Cycle_Counter CCR[5:0] + CYCTR[15:6] value,
depending on the programmed value in the bit 14 of TTCR0 (Timer Trigger Control Register 0) at
SOF.
For messages received into Mailboxes 30 and 31, Timestamp captures the TCNTR (Timer
Counter Register) value at SOF.
Message Transmit: For transmitted messages of Mailbox-15 to 1, Timestamp always captures the
CYCTR (Cycle Time Register) value or Cycle_Counter CCR[5:0] + CYCTR[15:6] value,
depending on the programmed value in the bit 14 of TTCR0 (Timer Trigger Control Register 0), at
SOF.
For messages transmitted from Mailboxes30 and 31, Timestamp captures the TCNTR (Timer
Counter Register) value at SOF.

Important: Please note that the TimeStamp is stored in a temporary register. Only after a
successful transmission or reception the value is then copied into the related Mailbox field. The
TimeStamp may also be updated if the CPU clears RXPR[N]/RFPR[N] at the same time that
UMSR[N] is set in overrun, however it can be read properly before clearing RXPR[N]/RFPR[N].

Tx-Trigger Time (TTT) and Time Trigger control
For Mailbox-29 to 24, when MBC is set to 000 (Bin) in time trigger mode (CMAX!= 3'b111), TxTrigger Time works as Time_Mark to determine the boundary between time windows. The TTT
and TT control are comprised of two 16-bit read/write areas as follows. Mailbox-30 doesn't have
TT control and works as Time_Ref.
Mailbox 30 to 24 can be used for reception if not used for transmission in TT mode. However they
cannot join the event trigger transmission queue when the TT mode is used.

note that once a merged arbitrating window is opened by TTW = 2'b10, the window must be

The first 16-bit area specifies the time that triggers the transmission of the message in cycle time.
The second 16-bit area specifies the basic cycle in the system matrix where the transmission must
start (Offset) and the frequency for periodic transmission. When the internal TTT register matches
to the CYCTR value, and the internal Offset matches to CCR value transmission is attempted from
the corresponding Mailbox. In order to enable this function, the CMAX (Cycle Maximum
Register) must be set to a value different from 3'b111, the Timer (TCNTR) must be running
(TTCR0 bit15 = 1), the corresponding MBC must be set to 3'b000 and the corresponding TXPR
bit must be set. Once TXPR is set by S/W, this module does not clear the corresponding TXPR bit
(among Mailbox-30 to 24) to carry on performing the periodic transmission. In order to stop the
periodic transmission, TXPR must be cleared by TXCR. Please note that in this case it is possible
that both TXACK and ABACK are set for the same Mailbox if TXACK is not cleared right after
completion of transmission. Please refer to figure 20.7.

Bit 10 - 8 — Test Mode (TST[2:0]): This bit enables/disables the test modes. Please note that
before activating the Test Mode it is requested to move this module into Halt mode or Reset mode.
This is to avoid that the transition to Test Mode could affect a transmission/reception in progress.
For details, please refer to section 20.4.1, Test Mode Settings.
Please note that the test modes are allowed only for diagnosis and tests and not when this module
is used in normal operation.

Bit 7 — Auto-wake Mode (MCR7): MCR7 enables or disables the Auto-wake mode. If this bit is
set, this module automatically cancels the sleep mode (MCR5) by detecting CAN bus activity
(dominant bit). If MCR7 is cleared this module does not automatically cancel the sleep mode.
This module cannot store the message that wakes it up.
Note: This bit can be modified only Reset or Halt mode.

Bit 6 — Halt during Bus Off (MCR6): MCR6 enables or disables entering Halt mode
immediately when MCR1 is set during Bus Off. This bit can be modified only in Reset or Halt
mode. Please note that when Halt is entered in Bus Off the CAN engine is also recovering
immediately to Error Active mode.

Bit 5 — Sleep Mode (MCR5): Enables or disables Sleep mode transition. If this bit is set, while
this module is in halt mode, the transition to sleep mode is enabled. Setting MCR5 is allowed after
entering Halt mode. The two Error Counters (REC, TEC) will remain the same during Sleep
mode. This mode will be exited in two ways:
1. by writing a '0' to this bit position,
2. or, if MCR[7] is enabled, after detecting a dominant bit on the CAN bus.
If Auto wake up mode is disabled, this module will ignore all CAN bus activities until the sleep
mode is terminated. When leaving this mode this module will synchronise to the CAN bus (by
checking for 11 recessive bits) before joining CAN Bus activity. This means that, when the No.2
method is used, this module will miss the first message to receive. CAN transceivers stand-by
mode will also be unable to cope with the first message when exiting stand by mode, and the S/W
needs to be designed in this manner.
In sleep mode only the following registers can be accessed: MCR, GSR, IRR and IMR.
Important: This module is required to be in Halt mode before requesting to enter in Sleep mode.
That allows the CPU to clear all pending interrupts before entering sleep mode. Once all interrupts
are cleared this module must leave the Halt mode and enter Sleep mode simultaneously (by
writing MCR[5] = 1 and MCR[1] = 0 at the same time).
Bit 5: MCR5
Description
0
This module sleep mode released (Initial value)
1
Transition to this module sleep mode enabled
Bit 4 — Reserved. The written value should always be '0' and the returned value is '0'.
Bit 3 — Reserved. The written value should always be '0' and the returned value is '0'.
Bit 2 — Message Transmission Priority (MCR2): MCR2 selects the order of transmission for
pending transmit data. If this bit is set, pending transmit data are sent in order of the bit position in
the Transmission Pending Register (TXPR). The order of transmission starts from Mailbox-31 as
the highest priority, and then down to Mailbox-1 (if those mailboxes are configured for
transmission). Please note that this feature cannot be used for time trigger transmission of the
Mailboxes 24 to 30.
If MCR2 is cleared, all messages for transmission are queued with respect to their priority (by
running internal arbitration). The highest priority message has the Arbitration Field (STDID + IDE
bit + EXTID (if IDE = 1) + RTR bit) with the lowest digital value and is transmitted first. The
internal arbitration includes the RTR bit and the IDE bit (internal arbitration works in the same

Description
0
Transmission order determined by message identifier priority (Initial value)
1
Transmission order determined by mailbox number priority (Mailbox-31
Mailbox-1)
Bit 1—Halt Request (MCR1): Setting the MCR1 bit causes the CAN controller to complete its
current operation and then enter Halt mode (where it is cut off from the CAN bus). This module
remains in Halt Mode until the MCR1 is cleared. During the Halt mode, the CAN Interface does
not join the CAN bus activity and does not store messages or transmit messages. All the user
registers (including Mailbox contents and TEC/REC) remain unchanged with the exception of
IRR0 and GSR4 which are used to notify the halt status itself. If the CAN bus is in idle or
intermission state regardless of MCR6, this module will enter Halt Mode within one Bit Time. If
MCR6 is set, a halt request during Bus Off will be also processed within one Bit Time. Otherwise
the full Bus Off recovery sequence will be performed beforehand. Entering the Halt Mode can be
notified by IRR0 and GSR4.
If both MCR14 and MCR6 are set, MCR1 is automatically set as soon as this module enters
BusOff.
In the Halt mode, this module configuration can be modified with the exception of the Bit Timing
setting, as it does not join the bus activity. MCR[1] has to be cleared by writing a '0' in order to rejoin the CAN bus. After this bit has been cleared, this module waits until it detects 11 recessive
bits, and then joins the CAN bus.
Notes: 1. After issuing a Halt request the CPU is not allowed to set TXPR or TXCR or clear
MCR1 until the transition to Halt mode is completed (notified by IRR0 and GSR4).
After MCR1 is set this can be cleared only after entering Halt mode or through a reset
operation (SW or HW).
2. Transition into or recovery from HALT mode, is only possible if the BCR1 and BCR0
registers are configured to a proper Baud Rate.

Bit 0 — Reset Request (MCR0): Controls resetting of this module. When this bit is changed
from '0' to '1' this module controller enters its reset routine, re-initialising the internal logic, which
then sets GSR3 and IRR0 to notify the reset mode. During a re-initialisation, all user registers are
initialised.
This module can be re-configured while this bit is set. This bit has to be cleared by writing a '0' to
join the CAN bus. After this bit is cleared, this module waits until it detects 11 recessive bits, and
then joins the CAN bus. The Baud Rate needs to be set up to a proper value in order to sample the
value on the CAN Bus.
After Power On Reset, this bit and GSR3 are always set. This means that a reset request has been
made and this module needs to be configured.
The Reset Request is equivalent to a Power On Reset but controlled by Software.

Bits 15 to 6: Reserved. The written value should always be '0' and the returned value is '0'.
Bit 5 — Error Passive Status Bit (GSR5): Indicates whether the CAN Interface is in Error
Passive or not. This bit will be set high as soon as this module enters the Error Passive state and is
cleared when the module enters again the Error Active state (this means the GSR5 will stay high
during Error Passive and during Bus Off). Consequently to find out the correct state both GSR5
and GSR0 must be considered.

The Bit Rate Calculation is:
Bit Rate =
fclk
2 × (BRP + 1) × (TSEG1 + TSEG2 + 1)
Where BRP is given by the register value and TSEG1 and TSEG2 are derived values from TSG1
and TSG2 register values. The '+1' in the above formula is for the Sync-Seg which duration is 1
time quanta.
fCLK = Peripheral Clock
BCR Setting Constraints
TSEG1min > TSEG2 SJWmax
(SJW = 1 to 4)
8 < TSEG1 + TSEG2 + 1 < 25 time quanta (TSEG1 + TSEG2 + 1 = 7 is not allowed)
TSEG2 > 2
These constraints allow the setting range shown in the table below for TSEG1 and TSEG2 in the
Bit Configuration Register. The number in the table shows possible setting of SJW. "No" shows
that there is no allowed combination of TSEG1 and TSEG2.

Example 1: To have a Bit rate of 500Kbps with a frequency of fclk = 24MHz it is possible to set:
BRP = 1, TSEG1 = 6, TSEG2 = 5.
Then the configuration to write is BCR1 = H'5400 and BCR0 = H'0001.
Example 2: To have a Bit rate of 500Kbps with a frequency of fclk = 36MHz it is possible to set:
BRP = 1, TSEG1 = 10, TSEG2 = 7.
Then the configuration to write is BCR1 = H'9600 and BCR0 = H'0001.

responsible to stop all transmission at the end of the current basic cycle (including test
modes)
Message error has occurred when in test mode. Note: If a Message Overload condition
occurs when in Test Mode, then this bit will not be set.
Bit 13: IRR13

Bit 12 – Bus activity while in sleep mode (IRR12): IRR12 indicates that a CAN bus activity is
present. While this module is in sleep mode and a dominant bit is detected on the CAN bus, this
bit is set. This interrupt is cleared by writing a '1' to this bit position. Writing a '0' has no effect. If
auto wakeup is not used and this interrupt is not requested it needs to be disabled by the related
interrupt mask register. If auto wake up is not used and this interrupt is requested it should be
cleared only after recovering from sleep mode. This is to avoid that a new falling edge of the
reception line causes the interrupt to get set again.
Please note that the setting time of this interrupt is different from the clearing time of GSR4.

Bit 10 — Start of new system matrix Interrupt (IRR10): Indicates that a new system matrix is
starting.
When CCR = 0, this bit is set at the successful completion of reception/transmission of time
reference message. Please note that when CMAX = 0 this interrupt is set at every basic cycle.
Bit 10: IRR10
Description
0

Cycle counter reached zero.
[Setting condition]
Reception/transmission of time reference message is successfully completed
when CMAX!= 3'b111 and CCR = 0
Bit 9 – Message Overrun/Overwrite Interrupt Flag (IRR9): Flag indicating that a message has
been received but the existing message in the matching Mailbox has not been read as the
corresponding RXPR or RFPR is already set to '1' and not yet cleared by the CPU. The received
message is either abandoned (overrun) or overwritten dependant upon the NMC (New Message
Control) bit. This bit is cleared when all bit in UMSR (Unread Message Status Register) are cleared
(by writing '1') or by setting MBIMR (MailBox interrupt Mast Register) for all UMSR flag set. It is also
cleared by writing a '1' to all the correspondent bit position in MBIMR. Writing to this bit position
has no effect.

Bit 8 - Mailbox Empty Interrupt Flag (IRR8): This bit is set when one of the messages set for
transmission has been successfully sent (corresponding TXACK flag is set) or has been
successfully aborted (corresponding ABACK flag is set). In Event Triggered mode the related
TXPR is also cleared and this mailbox is now ready to accept a new message data for the next
transmission. In Time Trigger mode TXPR for the Mailboxes from 30 to 24 is not cleared after a
successful transmission in order to keep transmitting at each programmed basic cycle. In effect,
this bit is set by an OR'ed signal of the TXACK and ABACK bits not masked by the
corresponding MBIMR flag. Therefore, this bit is automatically cleared when all the TXACK and
ABACK bits are cleared. It is also cleared by writing a '1' to all the correspondent bit position in
MBIMR. Writing to this bit position has no effect.
Bit 8: IRR8

Bit 7 - Overload Frame (IRR7): Flag indicating that this module has detected a condition that
should initiate the transmission of an overload frame. Note that in the condition of transmission
being prevented, such as listen only mode, an Overload Frame will NOT be transmitted, but IRR7
will still be set. IRR7 remains asserted until reset by writing a '1' to this bit position - writing a '0'
has no effect.
Bit 7: IRR7
Description

1
[Setting conditions] Overload condition detected
Bit 6 - Bus Off Interrupt Flag (IRR6): This bit is set when this module enters the Bus-off state
or when this module leaves Bus-off and returns to Error-Active. The cause therefore is the existing
condition TEC 256 at the node or the end of the Bus-off recovery sequence (128X11
consecutive recessive bits) or the transition from Bus Off to Halt (automatic or manual). This bit
remains set even if this module node leaves the bus-off condition, and needs to be explicitly
cleared by S/W. The S/W is expected to read the GSR0 to judge whether this module is in the busoff or error active status. It is cleared by writing a '1' to this bit position even if the node is still
bus-off. Writing a '0' has no effect.
Bit 6: IRR6
Description
0
[Clearing condition] Writing 1 (Initial value)
1
Enter Bus off state caused by transmit error or Error Active state returning
from Bus-off
[Setting condition]
When TEC becomes 256 or End of Bus-off after 128X11 consecutive
recessive bits or transition from Bus Off to Halt
Bit 5 - Error Passive Interrupt Flag (IRR5): Interrupt flag indicating the error passive state
caused by the transmit or receive error counter or by Error Passive forced by test mode. This bit is
reset by writing a '1' to this bit position, writing a '0' has no effect. If this bit is cleared the node
may still be error passive. Please note that the SW needs to check GSR0 and GSR5 to judge
whether this module is in Error Passive or Bus Off status.
Bit 5: IRR5
Description
0
[Clearing condition] Writing 1 (Initial value)

Bit 4 - Receive Error Counter Warning Interrupt Flag (IRR4): This bit becomes set if the
receive error counter (REC) reaches a value greater than 95 when this module is not in the Bus Off
status. The interrupt is reset by writing a '1' to this bit position, writing '0' has no effect.
Bit 4: IRR4

Bit 2 - Remote Frame Receive Interrupt Flag (IRR2): Flag indicating that a remote frame has
been received in a mailbox. This bit is set if at least one receive mailbox, with related MBIMR not
set, contains a remote frame transmission request. This bit is automatically cleared when all bits in
the Remote Frame Receive Pending Register (RFPR), are cleared. It is also cleared by writing a '1'
to all the correspondent bit position in MBIMR. Writing to this bit has no effect.
Bit 2: IRR2
Description
0
[Clearing condition] Clearing of all bits in RFPR (Initial value)
1
At least one remote request is pending
[Setting condition]
When remote frame is received and the corresponding MBIMR = 0
Bit 1 – Data Frame Received Interrupt Flag (IRR1): IRR1 indicates that there are pending Data
Frames received. If this bit is set at least one receive mailbox contains a pending message. This bit
is cleared when all bits in the Data Frame Receive Pending Register (RXPR) are cleared, i.e. there
is no pending message in any receiving mailbox. It is in effect a logical OR of the RXPR flags
from each configured receive mailbox with related MBIMR not set. It is also cleared by writing a
'1' to all the correspondent bit position in MBIMR. Writing to this bit has no effect.

Data frame received and stored in Mailbox
[Setting condition] When data is received and the corresponding MBIMR = 0
Bit 0 – Reset/Halt/Sleep Interrupt Flag (IRR0): This flag can get set for three different reasons.
It can indicate that:
1. Reset mode has been entered after a SW (MCR0) or HW reset
2. Halt mode has been entered after a Halt request (MCR1)
3. Sleep mode has been entered after a sleep request (MCR5) has been made while in Halt mode.
The GSR may be read after this bit is set to determine which state this module is in.
Important: When a Sleep mode request needs to be made, the Halt mode must be used
beforehand. Please refer to the MCR5 description and Figure 20.15 Halt Mode/Sleep Mode.
IRR0 is set by the transition from "0" to "1" of GSR3 or GSR4 or by transition from Halt mode to
Sleep mode. So, IRR0 is not set if this module enters Halt mode again right after exiting from Halt
mode, without GSR4 being cleared. Similarly, IRR0 is not set by direct transition from Sleep
mode to Halt Request. At the transition from Halt/Sleep mode to Transition/Reception, clearing
GSR4 needs (one-bit time - TSEG2) to (one-bit time * 2 - TSEG2).
In the case of Reset mode, IRR0 is set, however, the interrupt to the CPU is not asserted since
IMR0 is automatically set by initialisation.

Interrupt Mask Register (IMR)
The interrupt mask register is a 16 bit register that protects all corresponding interrupts in the
Interrupt Request Register (IRR) from generating an output signal on the IRQ. An interrupt
request is masked if the corresponding bit position is set to '1'. This register can be read or written
at any time. The IMR directly controls the generation of IRQ, but does not prevent the setting of
the corresponding bit in the IRR.

Transmit Error Counter (TEC) and Receive Error Counter (REC)
The Transmit Error Counter (TEC) and Receive Error Counter (REC) is a 16-bit read/(write)
register that functions as a counter indicating the number of transmit/receive message errors on the
CAN Interface. The count value is stipulated in the CAN protocol specification Refs. [1], [2], [3]
and [4]. When not in (Write Error Counter) test mode this register is read only, and can only be
modified by the CAN Interface. This register can be cleared by a Reset request (MCR0) or
entering to bus off.
In Write Error Counter test mode (i.e. TST[2:0] = 3'b100), it is possible to write to this register.
The same value can only be written to TEC/REC, and the value written into TEC is set to TEC
and REC. When writing to this register, this module needs to be put into Halt Mode. This feature
is only intended for test purposes.

The concatenation of TXPR1 and TXPR0 is a 32-bit register that contains any transmit pending
flags for the CAN module. In the case of 16-bit bus interface, Long Word access is carried out as
two consecutive word accesses.

The TXPR1 controls Mailbox-31 to Mailbox-16, and the TXPR0 controls Mailbox-15 to Mailbox1. The CPU may set the TXPR bits to affect any message being considered for transmission by
writing a '1' to the corresponding bit location. Writing a '0' has no effect, and TXPR cannot be
cleared by writing a '0' and must be cleared by setting the corresponding TXCR bits. TXPR may
be read by the CPU to determine which, if any, transmissions are pending or in progress. In effect
there is a transmit pending bit for all Mailboxes except for the Mailbox-0. Writing a '1' to a bit
location when the mailbox is not configured to transmit is not allowed.

Section 20 Controller Area Network
In Event Triggered Mode this module will clear a transmit pending flag after successful
transmission of its corresponding message or when a transmission abort is requested successfully
from the TXCR. In Time Trigger Mode, TXPR for the Mailboxes from 30 to 24 is NOT cleared
after a successful transmission, in order to keep transmitting at each programmed basic cycle. The
TXPR flag is not cleared if the message is not transmitted due to the CAN node losing the
arbitration process or due to errors on the CAN bus, and this module automatically tries to
transmit it again unless its DART bit (Disable Automatic Re-Transmission) is set in the MessageControl of the corresponding Mailbox. In such case (DART set), the transmission is cleared and
notified through Mailbox Empty Interrupt Flag (IRR8) and the correspondent bit within the Abort
Acknowledgement Register (ABACK).
If the status of the TXPR changes, this module shall ensure that in the identifier priority scheme
(MCR2 = 0), the highest priority message is always presented for transmission in an intelligent
way even under circumstances such as bus arbitration losses or errors on the CAN bus. Please
refer to the Application Note for details.
When this module changes the state of any TXPR bit position to a '0', an empty slot interrupt
(IRR8) may be generated. This indicates that either a successful or an aborted mailbox
transmission has just been made. If a message transmission is successful it is signalled in the
TXACK register, and if a message transmission abortion is successful it is signalled in the
ABACK register. By checking these registers, the contents of the Message of the corresponding
Mailbox may be modified to prepare for the next transmission.

Transmit Cancel Register (TXCR1, TXCR0)
The TXCR1 and TXCR0 are 16-bit read/conditionally-write registers. The TXCR1 controls
Mailbox-31 to Mailbox-16, and the TXCR0 controls Mailbox-15 to Mailbox-1.This register is
used by the CPU to request the pending transmission requests in the TXPR to be cancelled. To
clear the corresponding bit in the TXPR the CPU must write a '1' to the bit position in the TXCR.
Writing a '0' has no effect.
When an abort has succeeded the CAN controller clears the corresponding TXPR + TXCR bits,
and sets the corresponding ABACK bit. However, once a Mailbox has started a transmission, it
cannot be cancelled by this bit. In such a case, if the transmission finishes in success, the CAN
controller clears the corresponding TXPR + TXCR bit, and sets the corresponding TXACK bit,
however, if the transmission fails due to a bus arbitration loss or an error on the bus, the CAN
controller clears the corresponding TXPR + TXCR bit, and sets the corresponding ABACK bit. If
an attempt is made by the CPU to clear a mailbox transmission that is not transmit-pending it has
no effect. In this case the CPU will be not able at all to set the TXCR flag.

The ABACK1 and ABACK0 are 16-bit read/conditionally-write registers. These registers are used
to signal to the CPU that a mailbox transmission has been aborted as per its request. When an
abort has succeeded this module sets the corresponding bit in the ABACK register. The CPU may
clear the Abort Acknowledge bit by writing a '1' to the corresponding bit location. Writing a '0' has
no effect. An ABACK bit position is set by this module to acknowledge that a TXPR bit has been

configured by its MBC (Mailbox Configuration) to receive Data Frames. When a RXPR bit is set,
it also sets IRR1 (Data Frame Received Interrupt Flag) if its MBIMR (Mailbox Interrupt Mask
Register) is not set, and the interrupt signal is generated if IMR1 is not set. Please note that these

the bit may only be set if the mailbox is configured by its MBC (Mailbox Configuration) to
receive Remote Frames. When a RFPR bit is set, it also sets IRR2 (Remote Frame Receive
Interrupt Flag) if its MBIMR (Mailbox Interrupt Mask Register) is not set, and the interrupt signal
is generated if IMR2 is not set. Please note that these bits are only set by receiving Remote Frames

Mailbox Interrupt Mask Register (MBIMR)
The MBIMR1 and MBIMR0 are 16-bit read/write registers. The MBIMR only prevents the setting
of IRR related to the Mailbox activities, that are IRR[1] – Data Frame Received Interrupt, IRR[2]
– Remote Frame Receive Interrupt, IRR[8] – Mailbox Empty Interrupt, and IRR[9] – Message
OverRun/OverWrite Interrupt. If a mailbox is configured as receive, a mask at the corresponding
bit position prevents the generation of a receive interrupt (IRR[1] and IRR[2] and IRR[9]) but
does not prevent the setting of the corresponding bit in the RXPR or RFPR or UMSR. Similarly
when a mailbox has been configured for transmission, a mask prevents the generation of an
Interrupt signal and setting of an Mailbox Empty Interrupt due to successful transmission or
abortion of transmission (IRR[8]), however, it does not prevent this module from clearing the
corresponding TXPR/TXCR bit + setting the TXACK bit for successful transmission, and it does
not prevent this module from clearing the corresponding TXPR/TXCR bit + setting the ABACK
bit for abortion of the transmission.

Unread Message Status Register (UMSR)
This register is a 32-bit read/conditionally write register and it records the mailboxes whose
contents have not been accessed by the CPU prior to a new message being received. If the CPU
has not cleared the corresponding bit in the RXPR or RFPR when a new message for that mailbox
is received, the corresponding UMSR bit is set to '1'. This bit may be cleared by writing a '1' to the
corresponding bit location in the UMSR. Writing a '0' has no effect.
If a mailbox is configured as transmit box, the corresponding UMSR will not be set.

Cycle Counter Register (CCR)
This register is a 6-bit read/write register. Its purpose is to store the number of the basic cycle for
Time -Triggered Transmissions. Its value is updated in different fashions depending if this module
is programmed to work as a potential time master or as a time slave. If this module is working as
(potential) time master, CCR is:
Incremented by one every time the cycle time (CYCTR) matches to Tx-Trigger Time of
Mailbox-30 or
Overwritten with the value contained in MSG_DATA_0[5:0] of Mailbox 31 when a valid
reference message is received.
If this module is working as a time slave, CCR is only overwritten with the value of
MSG_DATA_0[5:0] of Mailbox 31 when a valid reference message is received.
If CMAX = 3'111, CCR is always H'0000.

Timer Counter Register (TCNTR)
This is a 16-bit read/write register that allows the CPU to monitor and modify the value of the
Free Running Timer Counter. When the Timer meets TCMR0 (Timer Compare Match Register 0)
+ TTCR0 [6] is set to '1', the TCNTR is cleared to H'0000 and starts running again. In TimeTrigger mode, this timer can be used as Local Time and TTCR0[6] has to be cleared to work as a
free running timer.
Notes: 1. It is possible to write into this register only when it is enabled by the bit 15 in TTCR0.
If TTCR0 bit15 = 0, TCNTR is always H'0000.
2. There could be a delay of a few clock cycles between the enabling of the timer and the
moment where TCNTR starts incrementing. This is caused by the internal logic used
for the pre-scaler.

Reference Mark Register (RFMK)
This register is a 16-bit read-only register. The purpose of this register is to capture Local Time
(TCNTR) at SOF of the reference message when the message is received or transmitted
successfully. In ET mode this register is not used and it is always cleared to zero.

Timer Compare Match Registers (TCMR0, TCMR1, TCMR2)
These three registers are 16-bit read/write registers and are capable of generating interrupt signals,
clearing-setting the Timer value (only supported by TCMR0) or clear the transmission messages
in the queue (only supported by TCMR2). TCMR0 is compared with TCNTR, however, TCMR1
and TCMR2 are compared with CYCTR.
The value used for the compare can be configured independently for each register. In order to set
flags, TTCR0 bit 12-10 needs to be set.
In Time-Trigger mode, TTCR0 bit6 has to be cleared by software to prevent TCNTR from being
cleared.
TMCR0 is for Init_Watch_Trigger, and TCMR2 is for Watch_Trigger.
Interrupt:
The interrupts are flagged by the Bit11, Bit15 and 14 in the IRR accordingly when a Compare
Match occurs, and setting these bits can be enabled by Bit12, Bit11, Bit10 in TTCR0. The
generation of interrupt signals itself can be prevented by the Bit11, Bit15 and Bit14 in the IMR.
When a Compare Match occurs and the IRR11 (or IRR15 or IRR14) is set, the Bit3 or Bit2 or Bit1
in the TSR (Timer Status Register) is also set. Clearing the IRR bit also clears the corresponding
bit of TSR.

Timer Clear-Set:
The Timer value can only be cleared when a Compare Match occurs if it is enabled by the Bit6 in
the TTCR0. TCMR1 and TCMR2 do not have this function.
Cancellation of the messages in the transmission queue:
The messages in the transmission queue can only be cleared by the TCMR2 through setting TXCR
when a Compare Match occurs while this module is not in the halt status. TCMR1 and TCMR0 do
not have this function.

Test Mode Settings
This module has various test modes. The register TST[2:0] (MCR[10:8]) is used to select this
module test mode. The default (initialised) settings allow this module to operate in Normal mode.
The following table is examples for test modes.
Test Mode can be selected only while in configuration mode. The user must then exit the
configuration mode (ensuring BCR0/BCR1 is set) in order to run the selected test mode.

Normal Mode:
This module operates in the normal mode.
Listen-Only Mode:
ISO-11898 requires this mode for baud rate detection. The Error Counters
are cleared and disabled so that the TEC/REC does not increase the values,
and the CTxn (n = 0, 1) Output is disabled so that this module does not
generate error frames or acknowledgment bits. IRR13 is set when a
message error occurs.
Self Test Mode 1:
This module generates its own Acknowledge bit, and can store its own
messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1)
pins must be connected to the CAN bus.

Section 20 Controller Area Network
Self Test Mode 2:
This module generates its own Acknowledge bit, and can store its own
messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1)
pins do not need to be connected to the CAN bus or any external devices,
as the internal CTxn (n = 0, 1) is looped back to the internal CRxn (n = 0,
1). CTxn (n = 0, 1) pin outputs only recessive bits and CRxn (n = 0, 1) pin
is disabled.
Write Error Counter:
TEC/REC can be written in this mode. This module can be forced to
become an Error Passive mode by writing a value greater than 127 into the
Error Counters. The value written into TEC is used to write into REC, so
only the same value can be set to these registers. Similarly, this module
can be forced to become an Error Warning by writing a value greater than
95 into them.
This module needs to be in Halt Mode when writing into TEC/REC
(MCR1 must be "1" when writing to the Error Counter). Furthermore this
test mode needs to be exited prior to leaving Halt mode.
Error Passive Mode:
This module can be forced to enter Error Passive mode.
Note: The REC will not be modified by implementing this Mode.
However, once running in Error Passive Mode, the REC will increase
normally should errors be received. In this Mode, this module will enter
BusOff if TEC reaches 256 (Dec). However when this mode is used this
module will not be able to become Error Active. Consequently, at the end
of the Bus Off recovery sequence, this module will move to Error Passive
and not to Error Active.
When message error occurs, IRR13 is set in all test modes.

Configuration of This Module
This module is considered in configuration mode or after a H/W (Power On Reset)/S/W (MCR[0])
reset or when in Halt mode. In both conditions this module cannot join the CAN Bus activity and
configuration changes have no impact on the traffic on the CAN Bus.
After a Reset request
The following sequence must be implemented to configure this module after (S/W or H/W) reset.
After reset, all the registers are initialised, therefore, this module needs to be configured before
joining the CAN bus activity. Please read the notes carefully.

If there is no TXPR set, RCAN-TL1 will receive the next incoming message. If there is a TXPR(s)
set, RCAN-TL1 will start transmission of the message and will be arbitrated by the CAN bus.
If it loses the arbitration, it will become a receiver.
Timer can be started at any time after the Timer Control regs and Tx-Trigger Time are set.

Halt mode
When this module is in Halt mode, it cannot take part to the CAN bus activity. Consequently the
user can modify all the requested registers without influencing existing traffic on the CAN Bus. It
is important for this that the user waits for this module to be in halt mode before to modify the
requested registers - note that the transition to Halt Mode is not always immediate (transition will
occurs when the CAN Bus is idle or in intermission). After this module transit to Halt Mode,
GSR4 is set.
Once the configuration is completed the Halt request needs to be released. This module will join
CAN Bus activity after the detection of 11 recessive bits on the CAN Bus.
Sleep mode
When this module is in sleep mode the clock for the main blocks of the IP is stopped in order to
reduce power consumption. Only the following user registers are clocked and can be accessed:
MCR, GSR, IRR and IMR. Interrupt related to transmission (TXACK and ABACK) and reception
(RXPR and RFPR) cannot be cleared when in sleep mode (as TXACK, ABACK, RXPR and
RFPR are not accessible) and must to be cleared beforehand.

3. MCR1 must not be cleared in SW, before GSR4 is set. MCR1 can be set automatically
in HW when this module moves to Bus Off and MCR14 and MCR6 are both set.
4. When MCR5 is cleared and MCR1 is set at the same time, this module moves to Halt

now ready to be updated for the next transmission, whereas, the GSR2 means that there is
currently no transmission request made (No TXPR flags set).

When a TXPR bit(s) is set while the CAN bus is idle, the internal arbitration starts running
immediately and the transmission is started.
Operations for both transmission and reception starts at SOF. Since there is no reception
frame, this module becomes transmitter.
At crc delimiter, internal arbitration to search next message transmitted starts.
Operations for both transmission and reception starts at SOF. Because of a reception frame
with higher priority, this module becomes receiver. Therefore, Reception is carried out
instead of transmitting Frame-3.
At crc delimiter, internal arbitration to search next message transmitted starts.
Operations for both transmission and reception starts at SOF. Since a transmission frame
has higher priority than reception one, this module becomes transmitter.
Internal arbitration for the next transmission is also performed at the beginning of each error
delimiter in case of an error is detected on the CAN Bus. It is also performed at the beginning of
error delimiters following overload frame.
As the arbitration for transmission is performed at CRC delimiter, in case a remote frame request
is received into a Mailbox with ATX = 1 the answer can join the arbitration for transmission only
at the following Bus Idle, CRC delimiter or Error Delimiter.
Depending on the status of the CAN bus, following the assertion of the TXCR, the corresponding
Message abortion can be handled with a delay of maximum 1 CAN Frame.

Time Triggered Transmission
This module offers a H/W support to perform communication in Time Trigger mode in line with
the emerging ISO-11898-4 Level 1 Specification.
This section reports the basic procedures to use this mode.
Setting Time Trigger Mode
In order to set up the time trigger mode the following settings need to be used.
CMAX in CMAX_TEW must be programmed to a value different from 3'b111.
Bit 15 in TTCR0 has to be set, to start TCNTR.
Bit 6 in TTCR0 has to be cleared to prevent TCNTR from being cleared after a match.
DART in Mailboxes used for time-triggered transmission cannot be used, since for Time
Triggered Mailboxes, TXPR is not cleared to support periodic transmission.

CCR is embedded into the first data byte of the time
reference message
{ Data0[7:6], CCR[5:0] } .
Setting Tx-Trigger Time
The Tx-Trigger Time(TTT) must be set in ascending order shown below, and the difference
between them has to satisfy the following expressions. TEW in the following expressions is the
register value.
TTT (Mailbox-24) < TTT (Mailbox-25) < TTT (Mailbox-26) < TTT (Mailbox-27) < TTT
(Mailbox-28) < TTT (Mailbox-29) < TTT (Mailbox-30)
and
TTT (Mailbox-i) – TTT (Mailbox- i-1) > TEW + the maximum frame length + 9
TTT (Mailbox-24) to TTT (Mailbox-29) correspond to Time_Marks, and TTT (Mailbox-30)
corresponds to Time_Ref showing the length of a basic cycle, respectively when working as
potential time master.

Function to be implemented by software
Some of the TTCAN functions need to be implemented in software. The main details are reported
hereafter. Please refer to ISO-11898-4 for more details.
Change from Init_Watch_Trigger to Watch_Trigger
This module offers the two registers TCMR0 and TCMR2 as H/W support for
Init_Watch_Trigger and Watch_Trigger respectively. The SW is requested to enable
TCMR0 and disable TCMR2 up to the first reference message is detected on the CAN Bus
and then disable TCMR0 and enable TCMR2.- Schedule Synchronization state machine.
Only reception of Next_is_Gap interrupt is supported. The application needs to take care of
stopping all transmission at the end of the current basic cycle by setting the related TXCR
flags.Master-Slave Mode control.
Only automatic cycle time synchronization and CCR increment is supported.
Message status count
Software has to count scheduling errors for periodic messages in exclusive windows.

Message Transmission Request for Time Triggered communication
When the Time Triggered mode is used communications must fulfils the ISO11898-4
requirements.
The following procedure should be used.
Send this module to reset or halt mode
Set TCMR0 to the Init_Watch_Trigger (0xFFFF)
Enable TCMR0 compare match setting bit 10 of TTCR0
Set TCMR2 to the specified Watch_Trigger value
Keep TCMR2 compare match disabled by keeping cleared the bit 12 of TTCR0
Set CMAX to the requested value (different from 111 bin)
Set TEW to the requested value
Configure the necessary Mailboxes for Time Trigger transmission and reception
Set LAFM for the 3 LSBs of Mailbox 31
Configure MCR, BCR1 and BCR0 to the requested values
If working as a potential time master:
Set RFTROFF to the requested Init_Ref_Offset value
Set TXPR for Mailbox 30
Write H'4000 into TTTSEL
Enable the TCNTR timer through the bit 15 of TTCR0
Move to Transmission_Reception mode
Wait for the reception or transmission of a valid reference message or for TCMR0 match
If the local time reaches the value of TCMR0 the Init_Watch_Trigger is reached and the
application needs to set TXCR for Mailbox 30 and start again
If the reference message is transmitted (TXACK[30] is set) set RFTROFF to zero
If a valid reference message is received (RXPR[31] is set) then:
If 3 LSBs of ID of Mailbox 31 have high priority than the 3 LSBs of Mailbox 30 (if
working as potential time master) keep RFTROFF to Init_Ref_Offset
If 3 LSBs of ID of Mailbox 31 have lower priority than the 3 LSBs of Mailbox 30 (if
working as potential time master) decrement by 1 the value in RFTROFF
Disable TCMR0 compare match by clearing bit 10 of TTCR0
Enable TCMR2 compare match by setting bit 12 of TTCR0
Only after two reference messages have been detected on the CAN Bus (transmitted or
received) can the application set TXPR for the other Time Triggered Mailboxes.

S/W has to ensure that a message is updated before a Tx trigger for transmission occurs.
When the CYCTR reaches to TTT (Tx-Trigger Time) of a Mailbox and CCR matches with the
programmed cycle for transmission, this module immediately transfers the message into the Tx
buffer. At this point, this module will attempt a transmission within the specified Time Enable
Window. If this module misses this time slot, it will suspend the transmission request up to the
next Tx Trigger, keeping the corresponding TXPR bit set to '1' if the transmission is periodic
(Mailbox-24 to 30). There are three factors that may cause this module to miss the time slot –
1. The CAN bus currently used
2. An error on the CAN bus during the time triggered message transmission
3. Arbitration loss during the time triggered message transmission

Section 20 Controller Area Network
In case of Merged Arbitrating Window the slot for transmission goes from the Tx_Trig of the
Mailbox opening the Window (TTW = 10 bin) to the end to the TEW of the Mailbox closing the
Window (TTW = 11 bin).The TXPR can be modified at any time. This module ensures the
transmission of Time Triggered messages is always scheduled correctly. However, in order to
guarantee the correct schedule, there are some important rules that are :
TTT (Tx Trigger Time) can be modified during configuration mode.
TTT cannot be set outside the range of Time_Ref, which specifies the length of basic cycle.
This could cause a scheduling problem.
TXPR is not automatically cleared for periodic transmission. If a periodic transmission
needs to be cancelled, the corresponding TXCR bit needs to be set by the application.

During merged arbitrating window, request by time-triggered transmission is served in the way of
FCFS (First Come First Served). For example, if Mailbox-25 cannot be transmitted between TxTrigger Time 25 (TTT25) and TTT26, Mailbox-25 has higher priority than Mailbox-26 between
TTT26 and 28.
MBC needs to be set into 3'b111, in order to disable time-triggered transmission. If this module is
Time Master, MBC[30] has to be 3'b000 and time reference window is automatically recognized
as arbitrating window.
Timer Operation
Figure 20.23 shows the timing diagram of the timer. By setting Tx-Trigger Time = n, time trigger
transmission starts between CYCTR = n + 2 and
CYCTR = n + 3.

During merged arbitrating window, event-trigger transmission is served after completion of timetriggered transmission. For example, If transmission of Mailbox-25 is completed and CYCTR
doesn't reach TTT26, event-trigger transmission starts based on message transmission priority
specified by MCR2. TXPR of time-triggered transmission is not cleared after transmission
completion, however, that of event-triggered transmission is cleared.
Note: that in the case that the TXPR is not set for the Mailbox which is assigned to close the
Merged Arbitrating Window (MAW), then the MAW will still be closed (at the end of the
TEW following the TTT of the assigned Mailbox.

When this module recognises the end of the Arbitration field while receiving a message, it starts
comparing the received identifier to the identifiers set in the Mailboxes, starting from Mailbox-31
down to Mailbox-0. It first checks the MBC if it is configured as a receive box, and reads LAFM,
and reads the CAN-ID of Mailbox-31 (if configured as receive) to finally compare them to the
received ID. If it does not match, the same check takes place at Mailbox-30 (if configured as
receive). Once this module finds a matching identifier, it stores the number of Mailbox-[N] into an
internal buffer, stops the search, and goes back to idle state, waiting for the EndOfFrame (EOF) to
come. When the 6th bit of EOF is notified by the CAN Interface logic, the received message is
written or abandoned, depending on the NMC bit. No modification of configuration during
communication is allowed. Entering Halt Mode is one of ways to modify configuration. If it is
written into the corresponding Mailbox, including the CAN-ID, i.e., there is a possibility that the
CAN-ID is overwritten by a different CAN-ID of the received message due to the LAFM used.
This also implies that, if the identifier of a received message matches to ID + LAFM of 2 or more
Mailboxes, the higher numbered Mailbox will always store the relevant messages and the lower
numbered Mailbox will never receive messages. Therefore, the settings of the identifiers and
LAFMs need to be carefully selected.
With regards to the reception of data and remote frames described in the above flow diagram the
clearing of the UMSR flag after the reading of IRR is to detect situations where a message is
overwritten by a new incoming message stored in the same mailbox (if its NMC = 1) while the
interrupt service routine is running. If during the final check of UMSR a overwrite condition is
detected the message needs to be discarded and read again.
In case UMSR is set and the Mailbox is configured for overrun (NMC = 0) the message is still
valid, however it is obsolete as it is not reflecting the latest message monitored on the CAN Bus.
Please access the full Mailbox content before clearing the related RXPR/RFPR flag.
Please note that in the case a received remote frame is overwritten by a data frame, both the
remote frame receive interrupt (IRR2) and data frame received interrupt (IRR1) and also the
Receive Flags (RXPR and RFPR) are set. In an analogous way, the overwriting of a data frame by
a remote frame, leads to setting both IRR2 and IRR1.
When a message is received and stored into a Mailbox all the fields of the data not received are
stored as zero. The same applies when a standard frame is received. The extended identifier part
(EXTID[17:0]) is written as zero.

Reconfiguration of Mailbox
When re-configuration of Mailboxes is required, the following procedures should be taken.
Change configuration of transmit box
Two cases are possible.
Change of ID, RTR, IDE, LAFM, Data, DLC, NMC, ATX, DART
This change is possible only when MBC = 3'b000. Confirm that the corresponding TXPR
is not set. The configuration (except MBC bit) can be changed at any time.
Change from transmit to receive configuration (MBC)
Confirm that the corresponding TXPR is not set. The configuration can be changed only in
Halt or reset state. Please note that it might take longer for this module to transit to halt
state if it is receiving or transmitting a message (as the transition to the halt state is delayed
until the end of the reception/transmission), and also this module will not be able to
receive/transmit messages during the Halt state.
In case this module is in the Bus Off state the transition to halt state depends on the
configuration of the bit 6 of MCR and also bit and 14 of MCR.
Change configuration (ID, RTR, IDE, LAFM, Data, DLC, NMC, ATX, DART, MBC) of
receiver box or Change receiver box to transmitter box
The configuration can be changed only in Halt Mode.
This module will not lose a message if the message is currently on the CAN bus and this
module is a receiver. This module will be moving into Halt Mode after completing the current
reception. Please note that it might take longer if this module is receiving or transmitting a
message (as the transition to the halt state is delayed until the end of the
reception/transmission), and also this module will not be able to receive/transmit messages
during the Halt Mode.
In case this module is in the Bus Off state the transition to halt mode depends on the
configuration of the bit 6 and 14 of MCR.

CAN Bus Interface
A bus transceiver IC is necessary to connect this LSI to a CAN bus. A Renesas HA13721
transceiver IC and its compatible products are recommended. As the CRx and CTx pins use 3 V,
an external level shifter is necessary. Figure 20.27 shows a sample connection diagram.

1. No ACK error is detected even when any other nodes are not connected to the CAN bus. This
occurs when channel 1 transmits an ACK in the ACK field in response to a message channel 0
has transmitted.
Channel 1 receives a message which channel 0 has transmitted on the CAN bus and then
transmits an ACK in the ACK field. After that, channel 0 receives the ACK.
To avoid this, make channel 1 which is not currently used for transmission the listen-only
mode (TST[2:0] = B'001) or the reset state (MCR0 = 1). With this setting, only a channel
which transmits a message transmits an ACK.
2. Internal arbitration for channels 0 and 1 is independently controlled to determine the order of
transmission.
Although the internal arbitration is performed on 31 Mailboxes at a time, it is not performed on
64 Mailboxes at a time even though multiple channels function as a single channel.
3. Do not set the same transmission message ID in both channels 0 and 1.
Two messages may be transmitted from the two channels after arbitration on the CAN bus.

This LSI has an on-chip one-channel IEBus controller. The Inter Equipment BusTM (IEBusTM)* is a
small-scale digital data transfer system for inter-equipment data transfer.
This LSI does not have an on-chip IEBus driver/receiver, so it is necessary to mount a dedicated
driver/receiver externally. In addition, as the IERxD and IETxD pins need 3V to operate, a
dedicated external level shifter is necessary.

Section 21 IEBusTM Controller
Determination of Bus Mastership (Arbitration)
A unit connected to the IEBus performs an operation to get the bus to control other units. This
operation is called arbitration. In arbitration, when multiple units start transferring simultaneously,
the bus mastership is given to one unit among them.
Only one unit can obtain bus mastership through arbitration, so the following priority for bus
mastership is determined.
(a)
Priority according to communications type
Broadcast communications (one-to-many communications) has priority over normal
communications (one-to-one communications).
(b)
Priority according to master address
The unit with the smallest master address has priority among units of the same communications
type.
Example: The master address is configured with 12 bits. A unit with H'000 has the highest
priority, while a unit with H'FFF has the lowest priority.
Note: When a unit loses in arbitration, the unit can automatically enter retransfer mode (0 to 7
retransfer times can be selected by the RN bit in IEMCR).

Notes:

Each unit connected to the IEBus should select a communications mode prior to
performing communications. Note that correct communications is not guaranteed if the
master and slave units do not adopt the same communications mode.
In the case of communications between a unit with IEB = 6 MHz and a unit with IEB =
6.29 MHz, correct communications are not possible even if the same communications
mode is adopted. Communications must be done with the same oscillation frequency.

Communications Address
In the IEBus, a specific 12-bit communications address is allocated to each individual unit. A
communications address is configured as follows.
Upper four bits: group number (number identifying a group to which the unit belongs)
Lower eight bits: unit number (number identifying individual units in a group)

Section 21 IEBusTM Controller
Broadcast Communications
In normal transfer, a single master unit communicates with a single slave unit, so one-to-one
transfer or reception takes place. In broadcast communications, a single master unit communicates
with multiple slave units. Since there are multiple slave units, no acknowledgements are returned
from the slave units during communications.
A broadcast bit decides whether broadcast or normal communications is done. (For details of the
broadcast bit, see section 21.1.2 (1) (b), Broadcast Bit.
There are two types of broadcast communications.
(a)
Group broadcast communications
Broadcast communications is aimed at units with the same group number, meaning that those units
have the same upper four bits of the communications address.
(b)
General broadcast communications
Broadcast communications is aimed at all units regardless of group number.
Group broadcast and general broadcast communications are identified by a slave address. (For
details on the slave address, see section 21.1.2 (3), Slave Address Field.)

Figure 21.1 Transfer Signal Format
(1)
Header
A header is comprised of a start bit and a broadcast bit.
(a)
Start Bit
The start bit is a signal to inform other units of the start of data transfer. A unit attempting to start
data transfer outputs a low-level signal (the start bit) for a specified period and then outputs the
broadcast bit.
If another unit is already outputting a start bit when a unit attempts to output a start bit, the unit
waits for completion of the start bit from the other unit without outputting its own start bit, and
then outputs the broadcast bit synchronized with the completion timing.
Other units enter the receive state after detecting the start bit.

SH7262 Group, SH7264 Group
(b)
Section 21 IEBusTM Controller
Broadcast Bit
The broadcast bit is a bit to identify the type of communications: broadcast or normal.
When this bit is cleared to 0, it indicates broadcast communications. When it is set to 1, it
indicates normal communications. Broadcast communications includes group broadcast and
general broadcast, which are identified by a value of the slave address. (For details of the slave
address, see section 21.1.2 (3), Slave Address Field.)
Since multiple slave units are communications destination units, in the case of broadcast
communications, the acknowledge bit is not returned from each field described in (2) and below.
When more than one unit starts to transfer a communications frame with the same timing,
broadcast communications has priority over normal communications, and arbitration occurs.
(2)
Master Address Field
The master address field is a field for transmitting the unit address (master address) to other units.
The master address field is comprised of master address bits and a parity bit.
The master address consists of 12 bits and the MSB is output first.
When more than one unit start to transfer broadcast bits having the same value with the same
timing, arbitration is decided by the master address field.
In the master address field, self-output data and data on the bus are compared for every one-bit
transfer. If the self-output master address and data on the bus are different, the unit that loses
arbitration will stop its transfer and enter the receive state.
Since the IEBus is configured with wired AND, the unit having the smallest master address of the
units in arbitration (arbitration master) wins in arbitration.
Finally, only a single unit remains in the transfer state as a master unit after outputting a 12-bit
master address.
Next, this master unit outputs a parity bit*, defines the master address for other units, and then
enters the slave address field output state.
Note: * Since even parity is used, when the number of one bit in the master address is odd, the
parity bit is 1.

SH7262 Group, SH7264 Group
Slave Address Field
The slave address field is a field to transmit an address (the slave address) of a unit (the slave unit)
to be transmitted. The slave address field is comprised of slave address bits, a parity bit, and an
acknowledge bit.
The slave address consists of 12 bits and the MSB is output first. The parity bit is output after the
12-bit slave address is transmitted to avoid receiving the slave address accidentally. The master
unit then detects the acknowledgement from the slave unit to confirm that the slave unit exists on
the bus. When the acknowledgement is detected, the master unit enters the control field output
state. However, the master unit enters the control field output state without detecting the
acknowledgement in broadcast communications.
The slave unit returns an acknowledgement when the slave addresses match and the parities of the
master and slave addresses are correct. When the parity of either the master or slave address is
incorrect, the slave unit decides that the master or slave address was not correctly received and
does not return the acknowledgement. In this case, the master unit enters the waiting (monitor)
state and communications ends.
In the case of broadcast communications, the slave address is used to identify the type of broadcast
communications (group or general) as follows:
When the slave address is H'FFF: General broadcast communications
When the slave address is other than H'FFF: Group broadcast communications
Note: The group number is the upper 4-bit value of the slave address in group broadcast
communications.
(4)
Control Field
The control field is a field for transmitting the type and direction of the following data field. The
control field is comprised of control bits, a parity bit, and an acknowledge bit.
The control bits consist of four bits and the MSB is output first.
The parity bit is output following the control bits. When the parity is correct, and the slave unit
can implement the function required from the master unit, the slave unit returns an
acknowledgement and enters the message length field output state. However, if the slave unit
cannot implement the requirements from the master unit even though the parity is correct, or if the
parity is not correct, the slave unit does not return an acknowledgement and returns to the waiting
(monitor) state.

The master unit enters the subsequent message length field output state after confirming the
acknowledgement.
When the acknowledgement is not confirmed, the master unit enters the waiting (monitor) state,
and communications ends. However, in the case of broadcast communications, the master unit
enters the following message length field output state without confirming the acknowledgement.
For details of the contents of the control bit, see table 21.4.
(5)
Message Length Field
The message length field is a field for specifying the number of transfer bytes. The message length
field is comprised of message length bits, a parity bit, and an acknowledge bit.
The message length has eight bits and the MSB is output first. Table 21.3 shows the number of
transfer bytes.

H'02

:

H'FF
255 bytes
H'00

Note: If a number greater than the maximum number of transfer bytes in one frame is specified,
communications are done in multiple frames depending on the communications mode. In
this case, the message length bits indicate the number of remaining communications data
after the first transfer. In this LSI, the message length bits must be smaller than the
maximum number of transfer bytes in one frame. Set these within the ranges shown below.
Mode 0: 1 to 16 bytes
Mode 1: 1 to 32 bytes
Mode 2: 1 to 128 bytes
This field operation differs depending on the value of bit 3 in the control field: master
transmission (the bit 3 of the control bits is 1) or master reception (the bit 3 of the control bits is
0).

Master Transmission
The master unit outputs the message length bits and the parity bit. When the parity is even, the
slave unit returns an acknowledgement and enters the following data field. Note that the slave unit
does not return an acknowledgement in broadcast communications.
When the parity is odd, the slave unit decides that the message length field is not correctly
received, does not return an acknowledgement, and returns to the waiting (monitor) state. In this
case, the master unit also returns to the waiting state and communications end.
(b)
Master Reception
The slave unit outputs the message length bits and parity bit. When even parity is confirmed, the
master unit returns an acknowledgement.
When the parity is not correct, the master unit decides that the message length bits are not
correctly received, does not return an acknowledgement, and returns to the waiting state. In this
case, the slave unit also returns to the waiting state and communications end.
(6)
Data Field
The data field is a field for data transmission/reception to and from the slave unit. The master unit
transmits/receives data to and from the slave unit using the data field. The data field is comprised
of data bits, a parity bit, and an acknowledge bit.
The data bits consist of eight bits and the MSB is output first.
The parity and acknowledge bits are output following the data bits from the master unit and slave
unit, respectively.
Broadcast communications are performed only for the transmission of the master unit. In this case,
the acknowledge bit is ignored. Operations in master transmission and master reception are
described below.

(a)
Section 21 IEBusTM Controller
Master Transmission
The master unit transmits the data bits and parity bit to the slave unit to write data from the master
unit to the slave unit. The slave unit receives the data bits and parity bit, and returns an
acknowledgement if the parity bit is even and the receive buffer is empty. If the parity bit is odd or
the receive buffer is not empty, the slave unit does not accept the corresponding data and does not
return an acknowledgement.
When the slave unit does not return an acknowledgement, the master unit retransmits the data.
This operation is repeated until either an acknowledgement from the slave unit is detected or the
maximum number of data transfer bytes is reached.
When the parity is even and the acknowledgement is output from the slave unit, the master unit
transmits the subsequent data if data remains and the maximum number of transfer bytes is not
exceeded.
In the case of broadcast communications, the slave unit does not return the acknowledgement, and
the master unit transfers data byte by byte.
(b)
Master Reception
The master unit outputs synchronous signals corresponding to all data bits to be read from the
slave unit.
The slave unit outputs the data bits and parity bit on the bus in accordance with the synchronous
signals from the master unit.
The master unit reads the parity bit output from the slave unit, and checks the parity. If the parity
is not even, or the receive buffer is not empty, the master unit rejects acceptance of the data, and
does not return the acknowledgement. The master unit reads the same data repeatedly if the
number of data does not exceed the maximum number of transfer bytes in one frame. If the parity
is even and the receive buffer is empty, the master unit accepts data and returns an
acknowledgement. The master unit reads in the subsequent data if the number of data does not
exceed the maximum number of transfer bytes in one frame.

The parity bit is used to confirm that transfer data occurs with no errors.
The parity bit is added to respective data of the master address, slave address, control, message
length, and data bits.
Even parity is used. When the number of bits having the value 1 is odd, the parity bit is 1. When
the number of bits having the value 1 is even, the parity bit is 0.

Notes: 1. Depending on the value of bit 3 (MSB), the transfer directions of the message length
bits in the following message length field and data in the data field vary.
When bit 3 is 1: Data is transferred from the master unit to the slave unit.
When bit 3 is 0: Data is transferred from the slave unit to the master unit.
2. H'3, H'6, H'A, and H'B are control bits to specify lock setting and cancellation.
When the undefined values of H'1, H'2, H'8, H'9, H'C, and H'D are transmitted, the
acknowledge signal is not returned.
When the control bits received from another unit which locked are not included in table 21.5, the
slave unit which has been locked by the master unit does not accept the control bits and does not
return the acknowledge bit.

Slave Status Read (Control Bits: H'0, H'6)
The master unit can decide the reason the slave unit does not return the acknowledgement (ACK)
by reading the slave status (H'0, H'6). The slave status indicates the result of the last
communications that the slave unit performed. All slave units can provide slave status
information. Figure 21.2 shows the bit configuration of the slave status.

2. The value of bit 4 can be selected by the STE bit in the IEBus master unit address register 1 (IEAR1).
3. The slave receive buffer is a buffer which is accessed during data write
(control bits: H'A, H'B, H'E, H'F).
In this LSI, the slave receive buffer corresponds to the IEBus receive buffer register (IERB001 to IERB128);
and bit 1 is the value of the RXBSY bit in the IEBus receive status register (IERSR).
4. The slave transmit buffer is a buffer which is accessed during data read
(control bits: H'3, H'7).
In this LSI, the slave transmit buffer corresponds to the IEBus transmit buffer register
(IETB001 to IETB128) and bit 0 is the value of the SRQ bit in the IEBus general flag registers (IEFLG).

Data Command Transfer (Control Bits: Read (H'3, H'7), Write (H'A, H'B, H'E, H'F))
In the case of data read (H'3, H'7), data in the data buffer of the slave unit is read in the master
unit. In the case of data write (H'B or H'F) or command write (H'A or H'E), data received in the
slave unit is processed in accordance with the operation specification of the slave unit.
Notes: 1. The user can select data and commands freely in accordance with the system.
2. H'3, H'A, or H'B may lock depending on the communications condition and status.
(3)
Locked Address Read (Control Bits: H'4, H'5)
In the case of the locked address read (H'4 or H'5), the address (12 bits) of the master unit, which
issues the lock instruction, is configured in bytes as shown in figure 21.3.

Locking/Unlocking (Control Bits: Setting (H'3, H'A, H'B), Cancellation: (H'6))
The lock function is used for message transfer over multiple communications frames. A locked
unit receives data only from the unit which locked it.
Locking and unlocking are described below.
(a)
Locking
When an acknowledge bit of 0 in the message length field is transmitted/received with the control
bits (H'3, H'A, H'B) indicating the lock operation, and then the communications frame is
completed before completion of data transmission/reception for the number of bytes specified by
the message length bits, the slave unit is locked by the master unit. In this case, the bit (bit 2)
relevant to locking in the byte data indicating the slave status is set to 1.
Lock is set only when the number of data exceeds the maximum number of transfer bytes in one
frame. Lock is not set by other error terminations.

(b)
Unlocking
When the control bits indicate the lock (H'3, H'A, or H'B) or unlock (H'6) operation and the byte
data for the number of bytes specified by the message length bits are transmitted/received in a
single communications frame, the slave unit is unlocked by the master unit. In this case, the bit
(bit 2) relevant to locking in the byte indicating the slave status is cleared to 0.
Note that locking and unlocking are not done in broadcast communications.
Note: * There are three ways to cause a locked unit to unlock itself.
Perform a power-on reset
Put the unit in deep standby mode
Issue an unlock command through the IEBus command register (IECMR)
Note that the LCK flag in IEFLG can be used to check whether the unit is locked or
unlocked.

For use of active low signals, levels are reversed from the active high signals.
The synchronous and data periods have approximately the same length.
The IEBus is synchronized bit by bit. The specifications for the time of all bits and the periods
allocated to the bits differ depending on the type of transfer bits and the unit (master or slave unit).

Broadcast Receive Error Interrupt Enable
If this bit is set to 1, a reception error interrupt occurs
when the receive buffer is not in the receive enabled
state during broadcast reception (when the RE bit is not
set to 1 or the RXBSY flag is set.). At this time, the
master address is stored in IEBus reception master
address register 1 and 2.
While this bit is 0, a reception error interrupt does not
occur when the receive buffer is not in the receive
enabled state, and the reception stops and enters the
wait state. The master address is not saved.
0: A broadcast receive error is not generated up to the
control field.
1: A broadcast receive error is generated up to the
control field.

Command
These bits issue a command to control

after the command issuance, the command is indicated
to be in execution. When the CMX flag becomes 0, the
operation state is entered.

Notes: 1. Do not execute this command in slave communications.
2. This command is valid during master communications (MRQ = 1). In other states, this
command issuance is ignored. If this command is issued in master communications, the
communications controller immediately enters the wait state. At this time, the issued
master transmission request ends (MRQ = 0).
3. This command is valid during slave communications (SRQ = 1). In other states, this
command issuance is ignored. Once this command is issued in slave transmission, the
SRQ flag is 0 before slave transmission. Therefore, a transmit request from the master
is not responded to. If a transmit request is issued during slave transmission, the
transmission stops and the wait state is entered (SRQ = 0).
4. Undefined bits. Issuing this command does not affect operation.

Receive Overrun Flag
Used to indicate the overrun during data reception. This
module sets this flag when this module receives the
next byte data while the receive data has not been read
(the RXBSY flag is not cleared). If this case, this
module assumes that an overrun error has occurred
and returns a NAK to the communications destination
unit.
The communications destination unit retransmits data
up to the maximum number of transmit bytes. This
module, however, returns a NAK when the RXBSY flag
remains set.
If the RXBSY flag is cleared to 0, this module returns
an ACK, and receives the next data.
In broadcast reception, if the RXBSY flag is set during
data receive start, this module immediately enters the
wait state. This flag becomes enabled only after the
receive start flag (RXS) is set.

Parity Error
Indicates that a parity error has occurred during data
field reception. If a parity error occurs before data field
reception, this module immediately enters the wait state
and the RXEPE flag is not set.
If a parity error occurs when the maximum number of
receive bytes in one frame have not been received, the
RXEPE flag is not set yet. When a parity error occurs,
this module returns a NAK to the communications
destination unit via the acknowledge bit. In this case,
the communications destination unit continues
retransfer up to the maximum number of receive bytes
in one frame and if the reception has been completed
normally by clearing the parity error, the RXEPE flag is
not set. If the parity error is not cleared when the
reception is terminated before receiving data for the
number of bytes specified by the message length, the
RXEPE flag is set.
In broadcast reception, if a parity error occurs during
data field reception, this module enters the wait state
immediately after setting the RXEPE flag. This flag is
enabled only after the receive start flag (RXS) is set. If
this error occurs before the receive start flag is set, this
module stops communication and enters the wait state.
This bit is not set in this case.
[Setting condition]
When the parity bit of the last data of the data field
is not correct after the maximum number of receive
bytes have been received
[Clearing condition]
Note:
*
When 1 is written
only 1 can be written to clear the flag.

Interrupt Sources
Interrupt sources for this module include the following:
Transmit start (TXS)
Transmit normal completion (TXF)
Arbitration loss (TXEAL)
Transmit timing error (TXETTME)
Overflow of the maximum number of transmit bytes in one frame (TXERO)
Acknowledge bits (TXEACK)
Receive busy (RXBSY)
Receive start (RXS)
Receive normal completion (RXF)
Broadcast Receive Error (RXEDE)
Receive overrun flag (RXEOVE)
Receive timing error (RXERTME)
Overflow of the maximum number of receive bytes in one frame (RXEDLE)
Parity error (RXEPE)
Each source has bits corresponding to the IEBus transmit interrupt enable register (IEIET) and the
IEBus receive interrupt enable register (IEIER) and can enable/disable interrupts. Each source also
has status flags corresponding to the IEBus transmit status register (IETSR) and IEBus receive
status register (IERSR). Reading the status flags allows determination of the interrupt sources.

Note on Operation when Transfer is Incomplete after Transfer of the Maximum
Number of Bytes
(1)
Data Transmission
When the maximum number of bytes defined by the communications mode have been transmitted
because a NAK has been received from the receive unit or transmission has not been completed
because the message length value exceeds the maximum number of transfer bytes in one frame,
this module sets the error flag and enters a wait state. At this time, transfer proceeds until the (n +
1)th byte has been transmitted, where n is the maximum number of transfer bytes. Then, when
NAK is received via the acknowledge bit of the (n + 1)th byte, the TXERO flag is set. If ACK is
received rather than NAK, the TXF flag is set.
Figure 21.18 shows the timing of operations when the maximum number of transfer bytes is
reached but transmission has not been completed.

Data Reception
When the data reception has not finished within the maximum number of bytes defined by the
communications mode because of a parity error or overrun error causing the retransfer of data, or
reception has not been completed because the message length value exceeds the maximum number
of transfer bytes in one frame, this module sets the error flag and enters a state of waiting for the
(n + 1)th byte of data, where n is the maximum number of transfer bytes. Thus, when data of the
(n + 1)th byte cannot be received, the receive timing error is detected and the RXERTME flag is
set. At this time, the RXEDLE flag is not set. The RXEDLE flag is set when the (n + 1)th byte is
received.
In the same way, when the maximum number of transfer bytes has been received and a parity error
has not been cleared, and the (n + 1)th byte cannot be received, the RXERTME flag is set. At this
time, the RXEPE flag is not set. The RXEPE flag is set when the (n + 1)th byte is received.
Figure 21.19 shows the timing of operations when the maximum number of transfer bytes has
been reached but reception is not complete.

Renesas SPDIF (IEC60958) Frame Format
The Renesas SPDIF frame consists of two subframes (for channels 1 and 2), each of which
contains a 4-bit preamble, audio data of up to 24 bits, a V flag, a user bit, a channel status bit, and
an even parity bit. Figure 22.3 shows the subframe format. According to this format, the Renesas
SPDIF performs biphase-mark modulation (channel coding) that will make the transmission line's
DC component a minimum value.

Figure 22.4 shows the block format, which consists of 192 continuous frames. One block begins at
the starting frame (preamble B) and ends at the 192nd frame (frame 191), and the preamble is used
to identify all subframes. Each block has a total of 384 subframes, which are classified into three
categories: subframe 0 indicating the beginning of a new block, subframe 1 (usually the channel
1), and subframe 2 (usually the channel 2). Usually, the music data sent and received by the
SPDIF is continuous so that continuous blocks appear.

Figure 22.4 Block Format
Table 22.2 shows the binary values of the Renesas SPDIF preambles. The polarity of these
preambles differs depending on the status of the preceding symbol (parity bit).

Note: As shown in figure 22.3, the even parity bit at time slot 31 of a subframe determines the
type of a preamble for one cycle of transmission. Usually, therefore, any one is selected
from the set states that are sent through the Renesas SPDIF. However, IEC60958 requires
decoding both types in view of connection with the preamble polarity reversed; the Renesas
SPDIF has preambles decoded according to table 22.2.
Channel status information is encoded at the rate of one bit per subframe, making the channel
status information per block have a total of 192 bits for each of subframes 1 and 2. For the format
of the channel status, refer to the IEC 60958 standard.

When an error bit is detected during DMA transfer, DMA transfer settings must be made
again. In this case, the Renesas SPDIF's module enable bit (either the RME or TME bit)
and the DMA enable bit (either the RDE or TDE bit) must be disabled and the error
status must be cleared before making DMA transfer settings again. Then the module
enable bit should be set and DMA transfer can be started again.

Transmitter User Data Register (TUI)
U-bit data in subframes is written in to this register. Because U-bit data is transmitted in a
sequence of subframes 1 and 2, you need to update the data on a 16-frame basis. For the contents
of the user bytes refer to the appropriate standard for the device in use. The user bits to be
transmitted are set in sequence starting at the LSB.

Transmitter Channel 1 Status Register (TLCS)
The 30-bit register stores the channel status information to be transmitted. For each channel,
channel status information per frame consists of 192 bits. Because necessary data covers only the
30 bits that are set in the following register, zeros continue to be sent after the transmission of the
first 30 bits.

Functional Description—Transmitter
22.8.1
Transmitter Module
Section 22 Renesas SPDIF Interface
The transmitter module transmits PCM data and auxiliary information after encoding it according
to the method of biphase-mark modulation that complies with the IEC60958 standard (SPDIF).
The clock for the transmitter module is an oversampling clock supplied from the outside. This
clock usually selects a value that serves as an oversample at a frequency eight times larger than the
clock frequency required for biphase-mark encoding. In this case, the clock frequency required to
transmit 32 time slots in a subframe is 512 times as large as the sample frequency for audio data.
Audio data and channel status information are first written into the module's channel 1 and then
into channel 2. Generally, the channel status need to be written only when the information
changes. The SPDIF module requests that the channel status be written in 30 frames -- when all
the current channel status data have been transmitted. You need to write somewhere between
frame 31 and the beginning of the next block of 192 frames.
The audio data is stored in a double buffer arrangement. To make sure that the first stage buffer is
empty, you can send an interrupt request or poll the status register. DMA transfers send channel 1
audio data on the first request and channel 2 data on the second.
The channel status information is stored in the 30-bit registers of channels 1 and 2. For each
channel, the channel status information per frame consists of 192 bits. Because necessary data
covers only 30 bits, zeros continue to be sent after the transmission of the first 30 bits until the
block is completed.
User data forms a 32-bit double buffer arrangement. You can make sure that the first stage buffer
is empty by either sending an interrupt request or polling the status register. Usually, information
about the user data will become insufficient with the length of data between blocks. Transmission
takes place in a sequence of channels 1 and 2. For the user data within a block, 384 bits are
transmitted before the next block is continuously transmitted.
The audio data handled by the Renesas SPDIF module is a linear PCM, making it possible to set
up to 24 bits. For this reason, the V flag indicating that audio data is a linear PCM remains to be 0.
The V flag involves no register-based setting. An even parity is created for each 32 bits of serial
output data (excluding the preamble).
Note: When transmitter user buffer underrun occurs, the current data in the buffer data of SPDIF
is transmitted until the next data is filled.

Transmitter Module Initialization
The device defaults to an idle state when it comes out of reset, or can be put into an idle state
when 0 is written to the TME bit in the CTRL register. When the transmitter module is idle, it has
the following settings:
The transmitter idle status bit (TIS) is set to 1, all other status bits are cleared to 0.
Preamble generation is invalid.
Synchronization between channels 1 and 2 is set to 0 (0 for channel 1, 1 for channel 2).
Both word_count and frame_count are set to 0.
The output from the biphase-mark encoder is set to 0.
Channel status, user and audio data registers will retain its value prior to putting the module into
idle. To exit the idle state the user must write 1 to the TME bit in the CTRL register.
22.8.3
Initial Settings for Transmitter Module
When the TME bit is set to 1, the TUIR and CSTX bits are set to 1. After that, if data is written in
the order of 1) TUI and 2) TLCS and TRCS, a channel status error will occur. To avoid this, be
sure to write data in the order of 1) TLCS and TRCS and 2) TUI.
Before writing the first audio data (write access to TLCA or TRCA by the CPU or write access to
TDAD by the DMA transfer) after setting the TME bit to 1, be sure to check that the CSTX and
TUIR bits are cleared by writing to TLCS, TRCS, and TUI.

Transmitter Module Data Transfer
Once the transmitter module has left the idle state, it is ready for data transfer. Data transfer timing
can be achieved in three ways. Either the transfer is done by interrupts, DMA requests or by
polling the status register. There is a shared interrupt line (for both transmit and receive) and a
single transmitter DMA request line.
Figure 22.5 shows a data transfer with an interrupt for the transmitter.

Channel status information is required to be updated when the information has changed. Because
the updating needs to be done before the transmission of the next block, the channel status to be
updated should be written after 30 frames have been sent; this is indicated either by an interrupt or
by polling the status bit. If channel status is written before 30 frames have been sent (while current
information is being sent) then an interrupt indicates that the channel status error bit (CSE) in the
status register has been set.
Note:
30 frames contains all the valid information in a single channel status block.

22.9
Functional Description—Receiver
22.9.1
Receiver Module
Section 22 Renesas SPDIF Interface
The receiver module demodulates data and clock signals from the input encoded according to the
IEC60958 standard. The encoded data, shown in linear PCM format, is stored into the audio data
register. The register also stores the channel status and user information being received
simultaneously as auxiliary information.
The main clock for the receiver module is an oversampling clock supplied from the outside. The
module operates at a frequency four times as large as the oversampling clock.
Note: The oversampling clock is the same for the transmitter and receiver.
Clock recovery is performed using a pulse width counter and averaging filters to produce a
sampling pulse in the middle of each bit in the datastream. A clock error status bit indicates clock
synchronization loss. Synchronization is achieved when a preamble occurs on the data stream for
the first time. Continuous adjustment prevents jitter and/or clock drift from affecting clock
recovery, provided that they fall within the clock recovery specifications.
Once the clock recovery is successful the biphase-mark decoder initiates its preamble detection.
The decoder searches for the start of block preamble (see table 22.2). A preamble error status bit
indicates that following preambles have not appeared at the correct time, such failures are most
likely caused by transmission loss or interference.
Even parity checking is performed on the decoded data. A discrepancy will result in the parity
error status bit being set.
The SPDIF module acquires user data and channel status information in addition to audio data.
The audio is stored in a double buffer arrangement. Either an interrupt request because of a full
buffer or polling of the status bit will indicate when the data is ready to be read. DMA transfers
receive channel 1 audio data on the first request and channel 2 data on the second.
Channel status is stored in a 30-bit register. Channel status information is received at 1-bit per
subframe. Therefore the registers will not be full until a total of 30 frames for each channel have
been received. New channel status is compared with the current data to see if it has changed and is
only read by the processor if it has. User data, which is also received at the same time, is stored
into the register on a subframe basis, so that the reception is completed when 16 frames are
reached.

Section 22 Renesas SPDIF Interface
Notes: 1. Channel status data requests do not support DMA.
2. When receiver user buffer overrun occurs, the current data in the buffer data of SPDIF
is overwritten by the next incoming data from SPDIF interface.
22.9.2
Receiver Module Initialization
The device defaults to an idle state when it comes out of reset, or can be put into an idle state by
writing 0 to bit RME in the CTRL register. Whilst idle the module has the following settings:
The receiver idle status bit is set to 1, all other status bits are cleared to 0.
Synchronization between channels 1 and 2 is set to 0 (0 for channel 1, 1 for channel 2).
Both Word_count and frame_count are set to 0.
Channel status registers, user data registers and audio data registers will retain its value prior to
putting the module into idle. To exit the idle state the user must write 1 to the bit RME in the
CTRL register.
22.9.3
Receiver Module Data Transfer
Once the module has left the idle state it is ready for data transfer. Data transfer timing can be
achieved in three ways. The transfer can be done by interrupts, or by polling the status register, or
by DMA. There is a shared interrupt line (transmit and receive) and a single receiver DMA request
line. Data transfer for the receiver can be interrupted by error signals caused by:
1. Clock recovery failure.
2. Transmission loss or interference – indicated by a preamble error.
3. Parity check failure.
Transmission loss or interference can cause the start of subframe or start of block preamble to be
misplaced or not present.
Parity check failure occurs when the parity bit is incorrect, this can be caused by any of the above.
Clock Recovery Deviation
The receive margin for clock recovery is based on the following equation:
M=

Eight times oversampling produces a receive margin = 39.25%
Four times oversampling produces a receive margin = 31.75%
Two times oversampling produces a receive margin = 16.75%
The fastest sample frequency is 48 kHz. This requires a clock speed of 128 48 kHz = 6.144
MHz. The worst case jitter in one cycle is specified at 40 ns = 24.5% of the period. This means
that an oversampling rate of 4 or more will satisfy the inequality and therefore be sufficient for
clock recovery.

Disabling the Module
22.10.1 Transmitter and Receiver Idle
The transmitter or receiver modules can be disabled by writing 0 to the idle bit in the control
register (TME for the transmitter and RME for the receiver). The idle state can be detected by
polling the idle bit in the status register (TIS and RIS).
22.11
Compressed Mode Data
Compressed mode data is defined in the IEC 61937 specification. This module only detects
compressed mode data. This is done by checking the parity flag (V flag) and bit 1 in the channel
status data. If both are one then the data is in compressed mode. This is indicated by the setting of
the CMD bit in the status register.
Note: Only the receiver detects compressed mode data since the information is not relevant to
the transmitter.

Usage Notes
22.13.1 Clearing TUIR
After TUI is written to, the TUIR bit is cleared only after transmission of a maximum of one frame
is completed. When using a transmitter user information interrupt to write data to TUI, check that
the TUIR bit is cleared before terminating the interrupt handling routine so that the interrupt is not
unexpectedly accepted again.
22.13.2 Frequency of Clock Input for Audio
The frequency of the clock input to the AUDIO_X1 and AUDIO_X2 or AUDIO_CLK must be
lower than the P frequency.

Section 23 CD-ROM Decoder
Section 23 CD-ROM Decoder
The CD-ROM decoder decodes streams of data transferred from the CD-DSP. When the medium
is CD-DA*1, the data stream is not input to the CD-ROM decoder because it consists of PCM data.
In the case of CD-ROM*2, the stream of data is input and the CD-ROM decoder performs sync
code detection and maintenance, descrambling, ECC correction, and EDC checking, and outputs
the resulting stream of data.
However, since the stream received by the CD-ROM decoder is assumed to consist of data from a
CD-ROM transferred via the serial sound interface, the decoder does not bother with the subcodes
defined in the CD-DA standard.

Features
Sync-code detection and maintenance
Detects sync codes from the CD-ROM and is capable of providing sync-code maintenance
(automatic interpolation of sync codes) when the sync code cannot be detected because of
defects such as scratches on the disc.
Five sector-synchronization modes are supported: automatic sync maintenance mode, external
sync mode, interpolated sync mode, and interpolated sync plus external sync mode.
Descrambling
ECC support
P-parity-based correction, Q-parity-based correction, PQ correction, and QP correction are
available.
PQ correction and QP correction can be applied repeatedly up to three times. This, however,
depends on the speed of the CD. For example, three iterations are possible when the CD-ROM
decoder is operating at 60 MHz with a double-speed CD drive.
Two buffers are provided due to the need for ECC correction. This allows parallel operation,
where ECC correction is performed in one buffer while the data stream is being received in the
other.
EDC checking
The EDC is checked before and after correction based on the ECC. Furthermore, an operating
mode is available in which, if the result of pre-correction EDC checking indicates no errors,
ECC correction is not performed regardless of the result of syndrome calculation.

Section 23 CD-ROM Decoder
Input data come from the internal bus and output data go out via the internal bus along a single
line each, but the bus bridge logic sets up branches for the register access port and stream data
port.
The stream data from the CD-DSP are transferred via the serial sound interface to the stream data
input control block. They are then subjected to descrambling, ECC correction, and EDC checking
as they pass through the CD-ROM decoder. After these processes, data from one sector are
obtained. The data are subsequently transferred to the stream-data buffer via the stream-data
output control block. Data can be transferred by either the direct memory access controller or the
CPU.
Figure 23.3 is a block diagram of the bus-bridge logic.
Since the input stream is transferred over the serial sound interface, transfer is relatively slow. On
the other hand, data from the output stream can be transferred at high speeds because they are
already in the core of the CD-ROM decoder. Since the data for output are buffered in SDRAM or
other memory, they must be transferred at high speeds in order to reduce the busy rate of the
SDRAM. For this reason, the data for the output stream are read out before the CD-ROM decoder
receives an output stream data read request from the internal bus. This allows the accumulation of
streaming data in the registers of the bus bridge, so that the data are ready for immediate output to
the internal bus upon a request from the internal bus. Accordingly, the reception of a request to
read from registers other than the stream-data registers after the stream data has already been read
out and stored in the register of the bus bridge is possible. To cope with this, the CD-ROM
decoder is provided with separate intermediary registers for the output stream-data register and the
other registers.

Section 23 CD-ROM Decoder
Figure 23.4 is a schematic diagram of the stream-data input control block. The stream-data input
controller contains logic that controls the stream of input data and a register that is used to change
the control mode of the CD-ROM decoder.
The serial sound interface mode used to transfer the stream data may affect the order (through the
endian setting) or lead to padding before the data is transferred. To handle the different
arrangements of data appropriately, the stream-data input control block includes a register for
changing the operating mode and generates signals to control the core of the CD-ROM decoder.
The data holding registers for the input stream consists of two 16-bit registers. The data holding
registers are controlled according to the mode set in the control register. For example, controlling
the order in which 16-bit data is supplied to the core of the CD-ROM decoder (sending the second
16-bytes first or vice versa). It is also possible to stop the supply of padding data to the core of the
CD-ROM decoder.

These bits select whether to change the order of 16-bit
units of data transferred from the serial sound interface
or suppress the stream data. In the serial sound
interface, either “padding mode” or “non-padding mode”
is selectable. In non-padding mode, each 32 bits of data
transferred from the serial sound interface are CD-ROM
data. Since the CD-ROM decoder has two 16-bit input

These bits select whether to change the order of 16-bit
units of data transferred from the serial sound interface
or suppress the stream data. In the serial sound
interface, either “padding mode” or “non-padding mode”
is selectable. In non-padding mode, each 32 bits of data
transferred from the serial sound interface are CD-ROM
data. Since the CD-ROM decoder has two 16-bit input
data registers, the order of the 16-bit data can be
swapped within the 32 bits. On the other hand, in
padding mode each 32 bits of data transferred from the
serial sound interface includes padding. Since the
padding is without meaning, it should be kept out of the

Endian Conversion for Data in the Input Stream
Stream data must be input to the core of the CD-ROM decoder in order according to the CD-ROM
data format specifications. In some systems, however, the order of the data from the serial sound
interface may have to be changed or the data will have been padded before transfer. To cope with
this, the stream data input control section is capable of swapping the order of the data and
preventing the input of padding data to the core of the CD-ROM decoder. These functions are
controlled through the serial sound interface data control register (SSI).
Figure 23.6 shows a case where the upper and lower 16 bits of the data, consisting of padding data
plus the first 2 bytes of sync code, that is, H'000000FF, are swapped (H'00FF0000) and input to
the CD-ROM decoder as the stream data.

Sync Code Maintenance Function
Each sector of CD-ROM data consists of 2352 bytes starting with
H'00FFFFFFFFFFFFFFFFFFFF00 (sync code). However, a scratch on the disc or some other
factor might lead to erroneous recognition of the sync code sequence at the wrong time.
Conversely, a sync code might not be detected at a point where it should be detected. As a solution
to these problems, the CD-ROM decoder of this LSI has a sync-code maintenance function, which
operates to ignore sync codes detected at abnormal times and maintain the appearance of the sync
code at the expected times when it is not actually detected on the disc.
The operating modes of the sync-code maintenance function are listed below. For details on the
settings, refer to section 23.3.2, Sync Code-Based Synchronization Control Register (CROMSY0),
and table 23.2.

Automatic Sync Maintenance Mode
In automatic sync maintenance mode, the sync code is ignored if detected within the one-sector
(2352-byte) period. Furthermore, if a sync code is not detected at the point where a next sector
should start, sync code maintenance is applied. If synchronization timing has changed, resynchronization is performed at the point where a sync code is detected within 2352 bytes after the
change.
Therefore, this mode is effective in rejecting abnormal sync patterns and following changes in
synchronization timing. Note, however, that this mode cannot achieve synchronization with the
first sector after a change to the synchronization timing.
Figure 23.8 shows operation in the case of normal sync-code detection, figure 23.9 shows a case
where a sync code is detected before a current one-sector period has elapsed, and figure 23.10
shows the case where the actual sync code is only detected some time after a full one-sector period
has elapsed.

External Sync Mode
In external sync mode, synchronization is always based on the sync codes in the incoming data.
Even if the next sync code is not detected at the 2352nd byte, decoding does not proceed until the
next sync code is detected.
Accordingly, this mode is effective in that it strictly follows the external synchronization timing.
Note, however, that decoding will not be performed normally when the sync-code pattern is input
with abnormal timing.
Figure 23.11 shows the operation in external sync mode.

Interpolated Sync Mode
In interpolated sync mode, synchronization is always driven by the internal counter after a sync
code pattern has been detected at the start of decoding. Accordingly, this mode is effective when
the sync patterns have been damaged.
However, decoding becomes incorrect after a change to the synchronization timing, since the
change in timing is not followed.

Interpolated Sync Plus External Sync Mode
In interpolated sync plus external sync mode, synchronization is based on the detected sync code
patterns as long as they are present, and if a sync pattern is not detected at the 2352nd byte, the
sync code maintenance is applied. Synchronization in this mode is more quickly responsive to
changes in synchronization timing than synchronization in the automatic sync maintenance mode.
However, decoding still becomes incorrect when a sync pattern is input with abnormal timing.
Figures 23.13 and 23.14 show the operation in interpolated sync plus external sync mode in the

Error Correction
The CD-ROM decoder handles data in the formats containing information relevant to error
correction, including the EDC, P parity, and Q parity. The CD-ROM decoder includes the
following functions for use in error correction.
Syndrome calculation
ECC correction
EDC checking
(1)
Syndrome Calculation
After the data of a sector in Mode 1 or Form 1 of Mode 2 has been input, the ECC is used in
correction if any error is detected (the result of syndrome calculation is non-zero). After
correction, the results of syndrome operation for the corrected data are output to bits ST_ECCP (P
parity) and ST_ECCQ (Q parity) in the CROMST6 register, respectively.
(2)
ECC correction and EDC Checking
For CD-ROM format data that contains EDC, P-parity, and Q-parity fields, the CD-ROM decoder
performs EDC checking and ECC correction. Supported correction modes are P correction, Q
correction, PQ correction (P correction followed by Q correction), and QP correction (Q
correction followed by P correction). In PQ and QP correction modes, up to three iterations of
correction are possible (the number of iterations is limited by the playback speed).
The EDC check is performed twice, before and after correction.
The mode of ECC correction and EDC checking is specified by bits MD_DEC[2:0] in the
CROMCTL1 register. When the PQ or QP correction mode is selected, the number of iterations is
specified by bits MD_PQREP[1:0] in the CROMCTL1 register.
When the automatic mode/form detection function is in use, the sector mode determines whether
or not ECC correction and EDC checking can be performed. For sectors in Mode 0 and Mode 2
(non-XA), which include neither parity bits nor EDC, ECC correction and EDC checking are not
performed. For sectors in Form 2 of Mode 2, ECC correction is not performed.
(a)
ECC Correction
When ECC correction is in use and an error in a sector is identified as non-correctable, the CDROM decoder generates an IERR interrupt and sets the ST_ECCNG bit of the CROMST6 register
to 1. The CD-ROM detector also sets this bit to 1 on detecting a short sector.
Page 1248 of 2108
R01UH0134EJ0400 Rev. 4.00
Sep 24, 2014
SH7262 Group, SH7264 Group
Section 23 CD-ROM Decoder
While the NO_ECC bit of the CROMCTL4 register is set to 1, a ‘pass’ result in pre-correction
EDC checking makes the CD-ROM decoder skip ECC correction, regardless of the results of the
syndrome operation.
(b)
EDC Checking
When EDC checking is in use, checking is in line with the specified or detected sector mode and
form, depending on whether or not automatic sector mode and form detection is selected.
The results of EDC checking before and after correction are reflected in the ST_EDC1 and
ST_EDC2 bits of the CROMST6 register, respectively. If EDC checking after ECC correction
indicates that an error remains, an IERR interrupt is generated.
23.4.4
Automatic Decoding Stop Function
Decoding can be stopped automatically in response to an error during the decoding of CD-ROM
data.
The possible conditions for automatically stopping the decoding process are listed below. The
applicable conditions are specified in the CROMCTL3 register.
An error is found to be not correctable by ECC correction.
Post-correction EDC checking indicates that an error remains.
A change of the sector mode or form.
A non-sequential MSF (minutes, seconds, frames (1/75 second)) value.
When automatic stopping is set up and any of the above conditions is encountered in a certain
sector, the decoding is stopped after the results of decoding for that sector have been output.
After decoding has been stopped in response to a condition specified in the CROMCTL3 register,
the condition can be identified by reading the CBUFST1 register.
The CD-ROM decoder has buffer space for two sectors. If input of the data stream continues and
the output stream of data is not read, the CD-ROM decoder stops at the point where the data of a
third sector starts to be input. At this time, the BUF_NG bit in the CBUFST2 register is set to 1,
but no interrupt is generated. Once the BUF_NG bit in the CBUFST2 register has been set to 1,
recovery can only be accomplished by using the LOGICRST bit in the ROMDECRST register to
reset the CD-ROM decoder function. When the LOGICRST bit in the ROMDECRST register is
set to 1, a reset signal is output and any registers in which settings have been made are cleared to
their initial values.

Target-Sector Buffering Function
In the CD-ROM decoder, the sector for output can be designated in two ways: automatic
buffering, where the CD-ROM decoder itself detects the presence of target sectors, and manual
buffering, where the target sector for output is designated by software and the software also
recognizes the sectors buffered in the CD-ROM decoder.
The following describes the procedures for setting the registers in the CD-ROM decoder to set up
automatic or manual buffering.
(1)
Setting Up Automatic Buffering
Figure 23.16 shows an example of setting up the automatic buffering. Set the relevant CD-ROM
decoder registers and start input of the data stream; the CD-ROM decoder then detects the target
sector and starts the output of the stream data.
Start of automatic buffering setup
Set both the CBUF_AUT and
CBUF_EN bits in CBUFCTL0 to 1
[1]
Set CBUFCTL1
[2]
[1] Turn on the automatic buffering function and
enable buffering in the buffer RAM.
[2] Set the minutes value of the target sector.
[3] Set the seconds value of the target sector.
[4] Set the frame value of the target sector.

Setting Up Manual Buffering
Figure 23.17 shows an example of setting up manual buffering. Each time an ISEC interrupt is
generated, the software checks whether or not the sector is the target sector and starts buffering
when the target sector is found.

Clear both the CBUF_AUT and
CBUF_EN bits in CBUFCTL0 to 0
[1]
[1] Turn off the automatic buffering function
and disable buffering in the buffer RAM.

ISEC Interrupt
This interrupt is generated when the sync code indicates a transition from sector to sector.
(2)
ITARG Interrupt
This interrupt is generated when the stream data transferred from the CD-DSP is not the data of
the target sector. The CD-ROM decoder checks the time data in the subcode. In correct operation,
data transfer is expected to start slightly before the target sector. An ITARG interrupt is generated
in the following cases.
When data of a sector preceding the target sector by quite a few sectors have been transferred
When data of a sector that comes after the target sector have been transferred
For the generation of this interrupt, ITARG is detected from the subcode. However, this interrupt
has no meaning in this LSI because CD-ROM data are transferred from the serial sound interface.

Section 23 CD-ROM Decoder
ISY Interrupt
This interrupt can be generated in the following cases.
When a sync code was detected at a position where the value in the word counter (counter for
checking sync code intervals) was not correct and the sync code was ignored
When a sync code has not been detected although the word counter has reached the final value
and a sync code has been interpolated (for sync maintenance)
When a sync code was detected at a position where the value in the word counter (counter for
checking sync code intervals) was not correct and the sync code was used in resynchronization
When a sync code has not been detected although the word counter has reached the final value,
so the period taken up by the sector has been prolonged
When the sector has been processed as a short sector with the aid of interpolated sync codes
When the sector has been processed as a long sector with the aid of interpolated sync codes
(4)
IERR Interrupt
This interrupt is generated in the following cases.
When ECC correction was incapable of correcting an error
When ECC correction was OK but the subsequent EDC check indicated an error
(5)
IBUF Interrupt
This interrupt is generated when the following transitions occur.
Data transfer to the buffer Data transfer complete (searching for data for the next transfer)
Data for transfer to the buffer are being searched for Data transfer started
(6)
IREADY Interrupt
This interrupt is generated when decoding of data for one sector is completed. This interrupt
should be used to start the CPU buffering stream data for output to SDRAM.
(7)
DMA Transfer Request
The source of direct memory access controller activation is the same as that of IREADY. An
interrupt request is generated when output stream data for one sector becomes ready, and after the
2768 bytes of data shown in figure 23.15 have been transferred, the request signal is negated once.
This is because a certain amount of time is required before the output data for the next sector is
ready, so the transfer request from the direct memory access controller should be turned off
between transfers.

23.5.2
SH7262 Group, SH7264 Group
Timing of Status Registers Updates
The status information registers of the CD-ROM decoder are updated on each ISEC interrupt. The
sector for which information is reflected in the status registers is selected by the ER0SEL bit of the
CROMCTL4 register.
23.6
Usage Notes
23.6.1
Stopping and Resuming Buffering Alone during Decoding
When the data of the output stream are being not read out but operation of the CD-ROM decoder
has continued until the buffers are full, the BUF_NG bit in the CBUFST2 register is set to 1; after
that, the CD-ROM decoder becomes incapable of operation.
To stop buffering alone, clear the CBUF_EN bit in the CBUFCTL0 register to 0. If the automatic
buffering function is in use, clear the CBUF_AUT in the CBUFCTL0 register to 0 at the same
time. In this case, the sectors currently in the buffers must be read out.
To resume automatic buffering, set the CBUF_AUT and CBUF_EN bits in the CBUFCTL0
register at the same time.
23.6.2
When CROMST0 Status Register Bits are Set
1. When the ST_SECS bit in the CROMST0 register becomes set, stop decoding immediately
and retry from one sector before the sector that was being decoded.
2. When the ST_SECL bit in the CROMST0 register becomes set, stop decoding immediately
and retry from two sectors before the sector that was being decoded.

23.6.3
Section 23 CD-ROM Decoder
Link Blocks
The CD-ROM decoder uses the header information before ECC correction to detect link blocks.
Accordingly, an input data stream that contains an error may be erroneously detected as a link
block. To prevent this, the following measures should be implemented in software.
During buffering (BUF_ACT = 1 in the CBUFST0 register), check the LINK_OUT1 bit in the
CROMST5 register on each ISEC interrupt. If it is set to 1, check to see if an IERR interrupt
has also occurred; if an IERR interrupt has not occurred, save the MFS values from the
HEAD20 to HEAD23 registers. If an IERR interrupt has occurred, do not save the MSF
values.
Perform the following processing for seven sectors (indicated by ISEC being generated seven
times) after finding that the LINK_OUT1 bit has been set to 1.
In either of cases 1 and 2 below,
1. LINK_ON = 1 (in the CROMST5 register) is confirmed at each ISEC interrupt, and
LINK_ON = 1 is detected again within the subsequent two-sector period
2. LINK_ON = 1 was not detected at any ISEC interrupt
Forcibly stop decoding, set the CROMSY0 register to place the decoder in external sync mode,
and retry decoding by specifying the MSF value stored above + 7 as the MSF value for the
target sector. The start sector address will be the address where RUN_OUT is stored + 7.
23.6.4
Stopping and Resuming CD-DSP Operation
When stopping and resuming the stream data input to the CD-ROM decoder, note that the input
data stream does not stop immediately before a sync code and that the CD-ROM decoder may
recognize the data as incorrect when the input stream is resumed. This happens because the system
holds a combination of the data up to the point where input was stopped and data that is input from
the point of resumption. Take care on this point when stopping and resuming input.
23.6.5
Note on Clearing the IREADY Flag
To clear the IREADY flag to 0 in interrupt processing etc., be sure to read one sector of data (2768
bytes) beforehand. If the IREADY flag is cleared to 0 before reading of one sector of data is
complete, decoding of the subsequent sectors will not be possible. For recovery from this
situation, write 1 to the LOGICRST bit in the CD-ROM decoder reset control register
(ROMDECRST), and then clear the bit to 0.

23.6.6
Note on Stream Data Transfer (1)
When reading of the stream data is slower than writing of the stream data, the buffer of the CDROM decoder will overflow. This causes the CD-ROM decoder to be abnormally stopped.
Caution is required in writing and reading of the stream data. Sample combinations of stream data
transfer settings are shown below.

Set bit 25 in the DMA channel control register (CHCR_n) to 1, as well as making the
regular settings for 16-byte transfer.
Note on Stream Data Transfer (2)
When reading the stream data, be sure to use either the direct memory access controller or the
CPU. If both the direct memory access controller and the CPU are used for reading, the stream
data may not be recognized as being in the CD-ROM format.

The sixteen A/D data registers, ADDRA to ADDRH, are 16-bit read-only registers that store the
results of A/D conversion.
An A/D conversion produces 10-bit data, which is transferred for storage into the ADDR
corresponding to the selected channel. The 10 bits of the result are stored in the upper bits (bits 15

Operation
The A/D converter uses the successive-approximation method, and the resolution is 10 bits. It has
three operating modes: single mode, multi mode, and scan mode. Switching the operating mode or
analog input channels must be done while the ADST bit in ADCSR is 0 to prevent incorrect
operation. The ADST bit can be set at the same time as the operating mode or analog input
channels are changed.
24.4.1
Single Mode
Single mode should be selected when only A/D conversion on one channel is required.
In single mode, A/D conversion is performed once for the specified one analog input channel, as
follows:
1. A/D conversion for the selected channel starts when the ADST bit in ADCSR is set to 1 by
software, the multi-function timer pulse unit 2, or external trigger input.
2. When A/D conversion is completed, the A/D conversion result is transferred to the A/D data
register corresponding to the channel.
3. After A/D conversion has completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set
to 1 at this time, an ADI interrupt request is generated.
4. The ADST bit that remains 1 during A/D conversion is automatically cleared to 0 when A/D
conversion is completed, and the A/D converter becomes idle.
When the operating mode or analog input channel selection must be changed during A/D
conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion.
After making the necessary changes, set the ADST bit to 1 to start A/D conversion again. The
ADST bit can be set at the same time as the mode or channel selection is switched.

Typical operations when a single channel (AN1) is selected in single mode are described next.
Figure 24.2 shows a timing diagram for this example (the bits which are set in this example belong
to ADCSR).
1. Single mode is selected, input channel AN1 is selected (CH[2:0] = 001), the A/D interrupt is
enabled (ADIE = 1), and A/D conversion is started (ADST = 1).
2. When A/D conversion is completed, the A/D conversion result is transferred into ADDRB. At
the same time the ADF flag is set to 1, the ADST bit is cleared to 0, and the A/D converter
becomes idle.
3. Since ADF = 1 and ADIE = 1, an ADI interrupt is requested.
4. The A/D interrupt handling routine starts.
5. The routine reads ADF = 1, and then writes 0 to the ADF flag.
6. The routine reads and processes the A/D conversion result (ADDRB).
7. Execution of the A/D interrupts handling routine ends. Then, when the ADST bit is set to 1,
A/D conversion starts and steps 2 to 7 are executed.

Section 24 A/D Converter
Multi Mode
Multi mode should be selected when performing A/D conversion once on one or more channels.
In multi mode, A/D conversion is performed once for a maximum of eight specified analog input
channels, as follows:
1. A/D conversion starts from the analog input channel with the lowest number (e.g. AN0, AN1,
…, AN3) when the ADST bit in ADCSR is set to 1 by software, the multi-function timer pulse
unit 2, or external trigger input.
2. When A/D conversion is completed on each channel, the A/D conversion result is sequentially
transferred to the A/D data register corresponding to that channel.
3. After A/D conversion on all selected channels has completed, the ADF bit in ADCSR is set to
1. If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated.
4. The ADST bit that remains 1 during A/D conversion is automatically cleared to 0 when A/D
conversion is completed, and the A/D converter becomes idle. If the ADST bit is cleared to 0
during A/D conversion, A/D conversion is halted and the A/D converter becomes idle. The
ADF bit is cleared by reading ADF while ADF = 1, then writing 0 to the ADF bit.
A/D conversion is to be performed once on all the specified channels. The conversion results are
transferred for storage into the A/D data registers corresponding to the channels.
When the operating mode or analog input channel selection must be changed during A/D
conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion.
After making the necessary changes, set the ADST bit to 1. A/D conversion will start again from
the first channel in the group. The ADST bit can be set at the same time as the mode or channel
selection is changed.
Typical operations when three channels (AN0 to AN2) are selected in multi mode are described
next. Figure 24.3 shows a timing diagram for this example.
1. Multi mode is selected (MDS2 = 1, MDS1 = 0), analog input channels AN0 to AN2 are
selected (CH[2:0] = 010), and A/D conversion is started (ADST = 1).
2. A/D conversion of the first channel (AN0) starts. When A/D conversion is completed, the A/D
conversion result is transferred into ADDRA.
3. Next, the second channel (AN1) is selected automatically and A/D conversion starts.
4. Conversion proceeds in the same way through the third channel (AN2).
5. When conversion of all selected channels (AN0 to AN2) is completed, the ADF flag is set to 1
and the ADST bit cleared to 0.
6. If the ADIE bit is set to 1 at this time, an ADI interrupt is requested.

Scan Mode
Scan mode is useful for monitoring analog inputs in a group of one or more channels at all times.
In scan mode, A/D conversion is performed sequentially for a maximum of eight specified analog
input channels, as follows:
1. A/D conversion starts from the analog input channel with the lowest number (e.g. AN0, AN1,
…, AN3) when the ADST bit in ADCSR is set to 1 by software, the multi-function timer pulse
unit 2, or external trigger input.
2. When A/D conversion is completed on each channel, the A/D conversion result is sequentially
transferred to the A/D data register corresponding to that channel.
3. After A/D conversion on all selected channels has completed, the ADF bit in ADCSR is set to
1. If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated. The A/D
converter starts A/D conversion again from the channel with the lowest number.
4. The ADST bit is not cleared automatically, so steps 2. and 3. are repeated as long as the ADST
bit remains set to 1. When the ADST bit is cleared to 0, A/D conversion halts and the A/D
converter becomes idle.
The ADF bit is cleared by reading ADF while ADF = 1, then writing 0 to the ADF bit.
When the operating mode or analog input channel selection must be changed during A/D
conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion.
After making the necessary changes, set the ADST bit to 1. A/D conversion will start again from
the first channel in the group. The ADST bit can be set at the same time as the mode or channel
selection is changed.
Typical operations when three channels (AN0 to AN2) are selected in scan mode are described as
follows. Figure 24.4 shows a timing diagram for this example.
1. Scan mode is selected (MDS2 = 1, MDS1 = 1), analog input channels AN0 to AN2 are
selected (CH[2:0] = 010), and A/D conversion is started (ADST = 1).
2. A/D conversion of the first channel (AN0) starts. When A/D conversion is completed, the A/D
conversion result is transferred into ADDRA.
3. Next, the second channel (AN1) is selected automatically and A/D conversion starts.
4. Conversion proceeds in the same way through the third channel (AN2).
5. When conversion of all the selected channels (AN0 to AN2) is completed, the ADF flag is set
to 1 and conversion of the first channel (AN0) starts again. If the ADIE bit is set to 1 at this
time, an ADI interrupt is requested.

6. The ADST bit is not cleared automatically, so steps 2. to 4. are repeated as long as the ADST
bit remains set to 1. When steps 2. to 4. are repeated, the ADF flag is kept to 1. When the
ADST bit is cleared to 0, A/D conversion stops. The ADF bit is cleared by reading ADF while
ADF = 1, then writing 0 to the ADF bit.
If both the ADF flag and ADIE bit are set to 1 while steps 2. to 4. are repeated, an ADI interrupt is
requested at all times. To generate an interrupt on completing conversion of the third channel,
clear the ADF bit to 0 after an interrupt is requested.

A/D Converter Activation by External Trigger or Multi-Function Timer Pulse Unit
2
The A/D converter can be independently activated by an external trigger or an A/D conversion
request from the multi-function timer pulse unit 2. To activate the A/D converter by an external
trigger or the multi-function timer pulse unit 2, set the A/D trigger enable bits (TRGS[3:0]). When
an external trigger or an A/D conversion request from the multi-function timer pulse unit 2 is
generated with this bit setting, the ADST bit is set to 1 to start A/D conversion. The channel
combination is determined by bits CH2 to CH0 in ADCSR. The timing from setting of the ADST
bit until the start of A/D conversion is the same as when 1 is written to the ADST bit by software.
24.4.5
Input Sampling and A/D Conversion Time
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at the A/D conversion start delay time (tD) after the ADST bit in ADCSR is set to 1, then
starts conversion. Figure 24.5 shows the A/D conversion timing. Table 24.4 indicates the A/D
conversion time.
As indicated in figure 24.5, the A/D conversion time (tCONV) includes tD and the input sampling
time(tSPL). The length of tD varies depending on the timing of the write access to ADCSR. The total
conversion time therefore varies within the ranges indicated in table 24.4.
In multi mode and scan mode, the values given in table 24.4 apply to the first conversion. In the
second and subsequent conversions, time is the values given in table 24.5.

External Trigger Input Timing
A/D conversion can also be externally triggered. When the TRGS[3:0] bits in ADCSR are set to
B'1001, an external trigger is input to the ADTRG pin. The ADST bit in ADCSR is set to 1 at the
falling edge of the ADTRG pin, thus starting A/D conversion. Other operations, regardless of the
operating mode, are the same as when the ADST bit has been set to 1 by software. Figure 24.6
shows the timing.

Interrupt Sources and DMA Transfer Request
The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion.
An ADI interrupt request is generated if the ADIE bit is set to 1 when the ADF bit in ADCSR is
set to 1 on completion of A/D conversion. Note that the direct memory access controller can be
activated by an ADI interrupt depending on the setting of the direct memory access controller. In
this case, an interrupt is not issued to the CPU. If the setting to activate the direct memory access
controller has not been made, an interrupt request is sent to the CPU. Having the converted data
read by the direct memory access controller in response to an ADI interrupt enables continuous
conversion to be achieved without imposing a load on software.
In single mode, set the direct memory access controller so that DMA transfer initiated by an ADI
interrupt is performed only once. In the case of A/D conversion on multiple channels in scan mode
or multi mode, setting the DMA transfer count to one causes DMA transfer to finish after
transferring only one channel of data. To make the direct memory access controller transfer all
conversion data, set the ADDR where A/D conversion data is stored as the transfer source address,
and the number of converted channels as the transfer count.
When the direct memory access controller is activated by ADI, the ADF bit in ADCSR is
automatically cleared to 0 when data is transferred by the direct memory access controller.

Definitions of A/D Conversion Accuracy
The A/D converter compares an analog value input from an analog input channel with its analog
reference value and converts it to 10-bit digital data. The absolute accuracy of this A/D conversion
is the deviation between the input analog value and the output digital value. It includes the
following errors:
Offset error
Full-scale error
Quantization error
Nonlinearity error
These four error quantities are explained below with reference to figure 24.7. In the figure, the 10bit A/D converter is illustrated as the 3-bit A/D converter for explanation. Offset error is the
deviation between actual and ideal A/D conversion characteristics when the digital output value
changes from the minimum (zero voltage) B'0000000000 (000 in the figure) to B'000000001 (001
in the figure)(figure 24.7, item (1)). Full-scale error is the deviation between actual and ideal A/D
conversion characteristics when the digital output value changes from B'1111111110 (110 in the
figure) to the maximum B'1111111111 (111 in the figure)(figure 24.7, item (2)). Quantization
error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB (figure 24.7, item (3)).
Nonlinearity error is the deviation between actual and ideal A/D conversion characteristics
between zero voltage and full-scale voltage (figure 24.7, item (4)). Note that it does not include
offset, full-scale, or quantization error.

Usage Notes
When using the A/D converter, note the following points.
24.7.1
Module Standby Mode Setting
Operation of the A/D converter can be disabled or enabled using the standby control register. The
initial setting is for operation of the A/D converter to be halted. Register access is enabled by
clearing module standby mode. For details, see section 33, Power-Down Modes.
24.7.2
Setting Analog Input Voltage
Permanent damage to the LSI may result if the following voltage ranges are exceeded.
1. Analog input range
During A/D conversion, voltages on the analog input pins ANn should not go beyond the
following range: AVss ANn AVcc (n = 0 to 7).
2. AVcc and AVss input voltages
Input voltages AVcc and AVss should be PVcc 0.3 V AVcc PVcc and AVss = Vss. Do
not leave the AVcc and AVss pins open when the A/D converter is not in use and in software
standby mode. When not in use, connect AVcc to the power supply (PVcc) and AVss to the
ground (Vss).
3. Setting range of AVref input voltage
Set the reference voltage range of the AVref pin as 3.0 V AVref AVcc.
24.7.3
Notes on Board Design
In board design, digital circuitry and analog circuitry should be as mutually isolated as possible,
and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close
proximity should be avoided as far as possible. Failure to do so may result in incorrect operation
of the analog circuitry due to inductance, adversely affecting A/D conversion values.
Digital circuitry must be isolated from the analog input signals (AN0 to AN3), analog reference
voltage (AVref), and analog power supply (AVcc) by the analog ground (AVss). Also, the analog
ground (AVss) should be connected at one point to a stable digital ground (Vss) on the board.

To prevent damage from voltage surges at the analog input pins (AN0 to AN7), connect an input
protection circuit like the one shown in figure 24.8. The circuit shown also includes a CR filter to
suppress noise. This circuit is shown as an example; the circuit constants should be selected
according to actual application conditions.

Permissible Signal Source Impedance
This LSI's analog input is designed such that conversion precision is guaranteed for an input signal
for which the signal source impedance is 5 k or less. This specification is provided to enable the
A/D converter's sample-and-hold circuit input capacitance to be charged within the sampling time;
if the sensor output impedance exceeds 5 k, charging may be insufficient and it may not be
possible to guarantee A/D conversion precision. However, for A/D conversion in single mode with
a large capacitance provided externally for A/D conversion in single mode, the input load will
essentially comprise only the internal input resistance of 3 k, and the signal source impedance is
ignored. However, as a low-pass filter effect is obtained in this case, it may not be possible to
follow an analog signal with a large differential coefficient (e.g., 5 mV/s or greater) (see
figure 24.10). When converting a high-speed analog signal, a low-impedance buffer should be
inserted.

Influences on Absolute Precision
Adding capacitance results in coupling with GND, and therefore noise in GND may adversely
affect absolute precision. Be sure to connect AVss, etc. to an electrically stable GND.
Care is also required to insure that filter circuits mounted on the board do not pick up interference
from digital signals (i.e., by acting as antennae).
24.7.7
Note on Usage in Scan Mode and Multi Mode
Starting conversion immediately after having stopped scan mode or multi mode operation may
lead to erroneous results of conversion.
To perform continuous conversion in such cases, set ADST to 0, wait for at least the A/D
conversion time for a single channel to elapse, and then start conversion (ADST = 1). (The A/D
conversion time for a single channel will vary according to the settings of the ADC registers.)

The NAND flash memory controller provides interfaces for an external NAND-type flash
memory. To take measures for errors specific to flash memory, the NAND flash memory
controller supports the ECC generation and error detection functions.
Up to 4-symbol ECC generator, error detector, and hardware error pattern generator have been
provided in addition to the 3-symbol ECC detector of the earlier products.

Features
NAND-Type Flash Memory Interface
Interface directly connectable to NAND-type flash memory
Read or write in sector units (512 + 16 bytes) and ECC processing executed
Read or write in byte units
Supports large-block (2048 + 64 bytes) flash memory*
Supports addresses for 2 Gbits and more by extension to 5-byte addresses
Note: * This module handles 512 + 16 bytes as a sector. For products with 2048 + 64 bytepages, this module divides a page into 512 +16 bytes units (i.e. four sectors per page)
for processing.
(2)
Access Modes: This module can select one of the following two access modes.
Command access mode: Performs an access by specifying a command to be issued from this
module to flash memory, address, and data size to be input or output. Read, write, or erasure of
data without ECC processing can be achieved.
Sector access mode: Performs a read or write in sector units by specifying a sector address and
controls ECC generation and check. By specifying the number of sectors, the continuous
physical sectors can be read or written.

Sectors and Control Codes
A sector is the basic unit of access and comprised of 512-byte data and 16-byte control code
fields. The control code field includes 8-byte ECC when the 3-symbol ECC circuit is used, and
10-byte ECC when the 4-symbol ECC circuit is used.
The position of the ECC in the control code field can be specified in 4-byte units when the 3symbol ECC circuit is used, and in 1-byte units when the 4-symbol ECC circuit is used.
User information can be written to the part of the control code field where ECC is not placed.
(4)
3-Symbol ECC
64 bits (8 bytes) of ECC is added to a sector, which consists of 512-byte data + 0/4/8-byte
control code.
Error correction and detection is up to three errors (30 bits at maximum) at random positions.
In a write operation, ECC is generated for the data and control code preceding the ECC. The
control code following the ECC is not considered.
In a read operation, an ECC error is checked for data and control code preceding the ECC. The
ECC on the control code in the FIFO are the results of checking replaced by the ECC circuit,
not the ECC read from flash memory.
Error correction is not performed even when an ECC error occurs. Error corrections must be
performed by software.
(5)
4-Symbol ECC
80 bits (10 bytes) of ECC is added to a sector, which consists of 512-byte data + 1-to 6-byte
control code.
Error correction and detection is up to four errors (40 bits at maximum) at random positions.
In a write operation, ECC is generated for the data and control code preceding the ECC. The
control code following the ECC is not considered.
In a read operation, an ECC error is checked for data and control code preceding the ECC. The
ECC on the control code in the FIFO are the results of checking replaced by the ECC circuit,
not the ECC read from flash memory.
The 4-symbol ECC circuit of this module has the capability of error correction pattern
generation by hardware, which is executed on a sector-by-sector basis.
In the error correction by hardware, addresses indicating the error positions and an error
pattern for correcting the errors are output. Data replacement must be performed by software.

Section 25 NAND Flash Memory Controller
Data Error
When a program error or erase error occurs, the error is reflected on the error source flags.
Interrupts for each source can be specified.
When a read error occurs, an ECC in the control code is other than 0. This read error is
reflected on the ECC error source flag.
When an ECC error occurs, perform an error correction, specify another sector to be replaced,
and copy the contents of the block to another sector as required.
(7)
Data Transfer FIFO and Data Register
The 224-byte data FIFO register (FLDTFIFO) is incorporated for data transfer of flash
memory.
The 32-byte control code FIFO register (FLECFIFO) is incorporated for data transfer of
control code.
(8)
DMA Transfer
By individually specifying the destinations of data and control code of flash memory to the
direct memory access controller, data and control code can be sent to different areas.
(9)
Access Time
The operating clock (FCLK) on the pins for the NAND-type flash memory is generated by
dividing the peripheral clock (P). The division ratio can be specified by the QTSEL bit in the
common control register (FLCMNCR).
Before changing the clock pulse generator configuration, this module must be placed in a
module stop state.
In NAND-type flash memory, the FRE and FWE pins operate at the frequency of FCLK. The
operating frequency must be specified within the maximum operating frequency of memory to
be connected.

Address Register (FLADR)
FLADR is a 32-bit readable/writable register that specifies the value to be output as an address.
The address of the size specified by ADRCNT[1:0] in the command control register is output
sequentially from ADR1 in byte units. By the sector access address specification bit (ADRMD) of
the command control register, it is possible to specify whether the sector number set in the address
data bits is converted into an address to be output to the flash memory.

Interrupt DMA Control Register (FLINTDMACR)
FLINTDMACR is a 32-bit readable/writable register that enables or disables DMA transfer
requests or interrupts. A transfer request from this module to the direct memory access controller
is issued after each access mode has been started.
Bits 9 to 5 are the flag bits that indicate various errors occurred in flash memory access and
whether there is a transfer request from the FIFO. Only 0 can be written to these bits. To clear a
flag, write 0 to the target flag bit and 1 to the other flag bits.

Ready Busy Timeout
Specify timeout time (the number of P clocks) in busy
state. When these bits are set to 0, timeout is not
generated.
25.3.10 Ready Busy Timeout Counter (FLBSYCNT)
FLBSYCNT is a 32-bit read-only register.
The status of flash memory obtained by the status read is stored in the bits STAT[7:0].
The timeout time set in the bits RBTMOUT[19:0] in FLBSYTMR is copied to the bits
RBTIMCNT[19:0] and counting down is started when the FRB pin is placed in a busy state. When
values in the RBTIMCNT[19:0] become 0, 1 is set to the BTOERB bit in FLINTDMACR, thus
notifying that a timeout error has occurred. In this case, an FLSTE interrupt request can be issued
if an interrupt is enabled by the RBERINTE bit in FLINTDMACR.

25.3.13 Transfer Control Register (FLTRCR)
Setting the TRSTRT bit to 1 initiates access to flash memory. Access completion can be checked
by the TREND bit. During the transfer (from when the TRSTRT bit is set to 1 until the TREND
bit is set to 1), the processing should not be forcibly ended (by setting the TRSTRT bit to 0).
When reading from flash memory, TREND is set when reading from flash memory have been
finished. However, if there is any read data remaining in the FIFO, the processing should not be
forcibly ended until all data has been read from the FIFO. While this module has the external bus
mastership and transfer is in progress, the SLEEP instruction should not be executed until the
TREND bit is set and transfer is completed.

Operation
25.4.1
Access Sequence
This module performs accesses in several independent stages.
For example, NAND-type flash memory programming consists of the following five stages.
First command issue stage (program setup command)
Address issue stage (program address)
Data stage (output)
Second command issue stage (program start command)
Status read stage
NAND-type flash memory programming access is achieved by executing these five stages
sequentially. An access to flash memory is completed at the end of the final stage (status read
stage).

Sector Access Mode
In sector access mode, flash memory can be read or programmed in sector units by specifying the
sector number of the sector to be accessed. In programming, an ECC is added. In read, an ECC
error check (detection) is performed.
Since 512-byte data is stored in FLDTFIFO and 16-byte control code is stored in FLECFIFO, the
DREQ1EN and DREQ0EN bits in FLINTDMACR can be set to transfer by the DMA.

ECC Error Correction
This module generates and adds ECC during write operation in sector access mode and performs
ECC error check during read operation in sector access mode. ECC processing is selectable
between 3-symbol ECC, the function provided in the earlier products, and 4-symbol ECC.
With 3-symbol ECC, only ECC generation and error detection are performed and error correction
is not performed. So, errors must be corrected by software. On the other hand, 4-symbol ECC is
capable of ECC generation, error detection, and error correction pattern generation by hardware.

Section 25 NAND Flash Memory Controller
Overview of 4-Symbol ECC Circuit
The 4-symbol ECC circuit in this module is capable of correcting up to 10 bits per symbol, which
makes a maximum of 40 bits for four symbols. However, the circuit corrects up to 32 bits because
the data in the flash memory data area is counted as eight bits per symbol.
Error correction pattern generation means generation of information necessary for correcting
errors, not execution of error correction. For details, see section 25.4.6, (3) 4-Symbol ECC Error
Correction Pattern Generation.
The 4-symbol ECC circuit is roughly divided into three stages (figure 25.15).
1. ECC generator
2. Error count detector
3. Error correction pattern generator
ECC generation and error count detection can be executed continuously while error correction
pattern generation is executed on a sector-by-sector basis.

4-Symbol ECC Operation
Figure 25.16 shows a flowchart of the operation when the 4-symbol ECC circuit is used. Setting
the 4ECCEN bit in FLCMNCR enables the 4-symbol ECC circuit and ECC is generated and
output for each sector. If the 4ECCCORRECT bit in FLCMNCR is also set to 1, information
necessary for correction pattern generation is accumulated in the 4-symbol ECC circuit.
In the case when the NAND flash memory controller is reading data from flash memory by
continuous sector access, the reading operation stops when an error-containing sector has been
read regardless of the number of remaining sectors. After reading of the error-containing sector
has ended, generation of error correction pattern is started by setting the FL4ECCCR register. If
the sector contains five or more errors, that sector is regarded as uncorrectable. Note that a sector
may be uncorrectable for some error patterns even if it contains four or less errors. In such a case,
invalid data are placed in the FL4ECCRES1 to FL4ECCRES4 registers.

4-Symbol ECC Error Correction Pattern Generation
The 4-symbol ECC circuit of this module can generate error correction patterns by hardware. The
original data can be restored by using the error correction patterns. Since the hardware processing
only covers generation of error correction patterns, processing for data restoration must be
provided by software.
The error correction patterns are output in the following format. The bits in a correction pattern at
error bit positions are set to 1, so the original data is restored by taking EOR of error data and error
correction pattern.
Example 1
Original data:
B'00000000
Erroneous data:
B'11111111
Correction pattern:
B'0011111111 (higher two bits are unnecessary data)
Recovered data:

Status Read
This module can read the status register of an AND/NAND-type flash memory. The data in the
status register is input through the I/O7 to I/O0 pins and stored in the bits STAT[7:0] in
FLBSYCNT, which can be read by the CPU. If a program error or erase error is detected when the
status register value is stored in the bits STAT[7:0] in FLBSYCNT, the STERB bit in
FLINTDMACR is set to 1 and generates an interrupt to the CPU if the STERINTE bit in
FLINTDMACR is enabled. If a status error occurs during continuous sector access, the TREND
bit in FLTRCR is set to 1 and the procedure stops.
(1)
Status Read of NAND-Type Flash Memory
The status register of NAND-type flash memory can be read by inputting command H'70 to
NAND-type flash memory. If programming is executed in command access mode or sector access
mode while the DOSR bit in FLCMDCR is set to 1, this module automatically inputs command
H'70 to NAND-type flash memory and reads the status register of NAND-type flash memory.
When the status register of NAND-type flash memory is read, the I/O7 to I/O0 pins indicate the
following information as described in table 25.3.

When the host controller function is selected: Fullspeed or low-speed operation is enabled.
1: High-speed operation is enabled (detected by this
module)
(1) When the host controller function is selected
When HSE = 0, the USB port performs low-speed
or full-speed operation.
Set HSE to 0 when connection of a low-speed
peripheral device to the USB port has been
detected.
When HSE = 1, this module executes the reset
handshake protocol, and automatically allows the
USB port to perform high-speed or full-speed
operation according to the protocol execution
result.
This bit should be modified after detecting device
connection (after detecting the ATTCH interrupt)
and before executing a USB bus reset (before
setting USBRESET to 1).
(2) When the function controller function is selected
When HSE = 0, this module performs full-speed
operation.
When HSE = 1, this module executes the reset

module to cancel pulling up the D+ line, thus notifying
the USB host of disconnection.
This bit should be set to 1 if the function controller

1: Remote wakeup signal is output.
The module controls the output time of a remote
wakeup signal. When this bit is set to 1, this module
clears this bit to 0 after outputting the 10-ms K state.
According to the USB specification, the USB bus idle
state must be kept for 5 ms or longer before a
remote wakeup signal is output. If this module writes
1 to this bit right after detection of suspended state,
the K state will be output after 2 ms.
Note: Do not write 1 to this bit, unless the device
state is in the suspended state (the DVSQ bit in
the INTSTS0 register is set to 1xx) and the
USB host enables the remote wakeup signal.
When this bit is set to 1, the internal clock must
not be stopped even in the suspended state
(write 1 to this bit while SCKE is 1).
This bit should be set to 0 if the host controller
function is selected.

Remote Wakeup Detection Enable
Enables or disables the downstream port peripheral
device to use the remote wakeup function (resume
signal output) when the host controller function is
selected.
0: Downstream port remote wakeup is disabled.
1: Downstream port remote wakeup is enabled.
With this bit set to 1, on detecting the remote wakeup
signal, this module detects the resume signal (Kstate for 2.5 s) from the downstream port device
and performs the resume process (drives the port to
the K-state).
With this bit set to 0, this module ignores the
detected remote wakeup signal (K-state) from the
peripheral device connected to the downstream port.
While this bit is 1, the internal clock should not be
stopped even in the suspended state (SCKE should
be set to 1). Also note that the USB bus should not
be reset from the suspended state (USBRST should
not be set to 1); it is prohibited by USB Specification
2.0.
This bit should be set to 0 if the function controller
function is selected.

Bus Reset Output
Controls the USB bus reset signal output when the

0: USB bus reset signal is not output.
1: USB bus reset signal is output.
When the host controller function is selected, setting
this bit to 1 allows this module to drive the USB port
to SE0 to reset the USB bus. Here, this module
performs the reset handshake protocol if the HSE bit

This module continues outputting SE0 while
USBRST is 1 (until 0 is written to USBRST).
USBRST should be 1 (= USB bus reset period) for
the time defined by USB Specification 2.0.
Writing 1 to this bit during communication (UACT =
1) or during the resume process (RESUME = 1)
prevents this module from starting the USB bus reset
process until both UACT and RESUME become 0.

(1) When the host controller function is selected
These bits can be set after writing 1 to DRPD. This
module outputs waveforms when both DRPD and
UACT are set to 1. This module also performs highspeed termination after the UTST bits are written to.
Procedure for setting the UTST bits
1. Power-on reset.
2. Start the clock supply (Set SCKE to 1 after
the crystal oscillation and the PLL for USB
are settled).
3. Set DCFM and DRPD to 1 (setting HSE to 1
is not required).
4. Set USBE to 1.
5. Set the UTST bits to the appropriate value
according to the test specifications.
6. Set the UACT bit to 1.
Procedure for modifying the UTST bits
1. (In the state after executing step 6 above)
Set UACT and USBE to 0.
2. Set USBE to 1.
3. Set the UTST bits to the appropriate value
according to the test specifications.
4. Set the UACT bit to 1.
When these bits are set to Test_SE0_NAK (1011),
this module does not output the SOF packet even
when 1 is set to UACT.
When these bits are set to Test_Force_Enable
(1101), this module outputs the SOF packet when 1
is set to UACT. In this test mode, this module does
not perform hardware control consequent to
detection of high-speed disconnection (detection of
the DTCH interrupt).
When setting the UTST bits, the PID bits for all the
pipes should be set to NAK.
To return to normal USB communication after a test
mode has been set and executed, a power-on reset
should be applied.

FIFO Port Registers (CFIFO, D0FIFO, D1FIFO)
CFIFO, D0FIFO and D1FIFO are port registers that are used to read data from the FIFO buffer
memory and writing data to the FIFO buffer memory.
There are three FIFO ports: the CFIFO, D0FIFO and D1FIFO ports. Each FIFO port is configured
of a port register (CFIFO, D0FIFO, D1FIFO) that handles reading of data from the FIFO buffer
memory and writing of data to the FIFO buffer memory, a select register (CFIFOSEL,
D0FIFOSEL, D1FIFOSEL) that is used to select the pipe assigned to the FIFO port, and a control
register (CFIFOCTR, D0FIFOCTR, D1FIFOCTR).
Each FIFO port has the following features.
The DCP FIFO buffer should be accessed through the CFIFO port.
Accessing the FIFO buffer using DMA transfer should be performed through the D0FIFO or
D1FIFO port.
The D1FIFO and D0FIFO ports can be accessed also by the CPU.
When using functions specific to the FIFO port, the pipe number (selected pipe) specified by
the CURPIPE bits cannot be changed (when the DMA transfer function is used, etc.).
Registers configuring a FIFO port do not affect other FIFO ports.
The same pipe should not be assigned to two or more FIFO ports.
There are two FIFO buffer states: the access right is on the CPU side and it is on the SIE side.
When the FIFO buffer access right is on the SIE side, the FIFO buffer cannot be accessed from
the CPU.
These registers are initialized by a power-on reset.

to check that FRDY is 1.
To re-write to the FIFO buffer again from the first

Buffer Memory Valid Flag
This bit should be set to 1 when data has been
completely written to the FIFO buffer on the CPU
side for the pipe selected using the CURPIPE bits
(selected pipe).
0: Invalid
1: Writing ended
When the selected pipe is in the transmitting
direction, set this bit to 1 in the following cases.
Then, this module switches the FIFO buffer from the
CPU side to the SIE side, enabling transmission.
To transmit a short packet, set this bit to 1 after
data has been written.
To transmit a zero-length packet, set this bit to 1
before data is written to the FIFO buffer.
Set this bit to 1 after the number of data bytes
has been written for the pipe in continuous
transfer mode, where the number is a natural
integer multiple of the maximum packet size and
less than the buffer size.
When the data of the maximum packet size has been
written for the pipe in non-continuous transfer mode,
this module sets this bit to 1 and switches the FIFO
buffer from the CPU side to the SIE side, enabling
transmission.
When the selected pipe is in the transmitting
direction, if 1 is written to BVAL and BCLR bits
simultaneously, this module clears the data that has
been written before it, enabling transmission of a
zero-length packet.
Writing 1 to this bit should be done while FRDY
indicates 1 (set by this module).
When the selected pipe is in the receiving direction,
do not set this bit to 1.

When double buffer mode is set for the FIFO buffer
assigned to the selected pipe, this module clears
only one plane of the FIFO buffer even when both
planes are read-enabled.
When the selected pipe is the DCP, setting BCLR to
1 allows this module to clear the FIFO buffer
regardless of whether the FIFO buffer is on the CPU
side or SIE side. To clear the buffer on the SIE side,
set the PID bits for the DCP to NAK before setting
BCLR to 1.
When the selected pipe is not the DCP, writing 1 to

there is no data to be read. In these cases, set BCLR

Receive Data Length
Indicates the length of the receive data.
While the FIFO buffer is being read, these bits
indicate the different values depending on the RCNT
bit value as described below.
RCNT = 0:
This module sets these bits to indicate the length
of the receive data until all the received data has
been read from a single FIFO buffer plane.
While BFRE is 1, these bits retain the length of
the receive data until BCLR is set to 1 even after
all the data has been read.
RCNT = 1:
This module decrements the value indicated by
these bits each time data is read from the FIFO
buffer. (The value is decremented by one when
MBW is 00, by two when MBW is 01, and by four
when MBW is 10.)
This module sets these bits to 0 when all the data
has been read from one FIFO buffer plane. However,
in double buffer mode, if data has been received in
one FIFO buffer plane before all the data has been
read from the other plane, this module sets these bits
to indicate the length of the receive data in the
former plane when all the data has been read from
the latter plane.
Note: When RCNT is 1, it takes 10 bus cycles for
these bits to be updated after the FIFO port has been
read.
Notes: 1. Only 0 can be read and 1 can be written.
2. Only 1 can be written.

26.3.14 BEMP Interrupt Enable Register (BEMPENB)
BEMPENB is a register that enables or disables the BEMP bit in INTSTS0 to be set to 1 when the
BEMP interrupt is detected for each pipe.
On detecting the BEMP interrupt for the pipe corresponding to the bit in this register that has been
set to 1, this module sets 1 to the corresponding PIPEBEMP bit in BEMPSTS and the BEMP bit in
INTSTS0, and generates the BEMP interrupt.
While at least one PIPEBEMP bit in BEMPSTS indicates 1, this module generates the BEMP
interrupt when the corresponding interrupt enable bit in BEMPENB is modified from 0 to 1.
This register is initialized by a power-on reset.

This bit is initialized to B'0 by a power-on reset and B'1 by a USB bus reset.
These bits are initialized to B'000 by a power-on reset and B'001 by a USB bus reset.
This bit is initialized to 0 when the level of the VBUS pin input is high and 1 when low.
To clear the VBINT, RESM, SOFR, DVST, or CTRT bit, write 0 only to the bits to be
cleared; write 1 to the other bits. Do not write 0 to the status bits indicating 0.
5. This module can detect a change in the status indicated by the VBINT and RESM bits
even while the clock supply is stopped (while SCKE is 0), and outputs interrupts when
the corresponding interrupt enable bits are enabled. Clearing the status should be done
after enabling the clock supply.
6. A change in the status of the RESM, DVST, and CTRT bits occur only when the

Overrun/Underrun Detection Status
Indicates whether an overrun/underrun error has
been detected in the pipe during isochronous
transfer.
0: No error
1: An error occurred
This bit can be cleared to 0 by writing 0 to the bit.
(1) When the host controller function is selected
This module sets this bit to 1 on any of the
following conditions.
For the isochronous transfer pipe in the
transmitting direction, the time to issue an OUT
token comes before all the transmit data has
been written to the FIFO buffer.
For the isochronous transfer pipe in the receiving
direction, the time to issue an IN token comes
when no FIFO buffer planes are empty.
(2) When the function controller function is selected
This module sets this bit to 1 on any of the
following conditions.
For the isochronous transfer pipe in the
transmitting direction, the IN token is received
before all the transmit data has been written to
the FIFO buffer.
For the isochronous transfer pipe in the receiving
direction, the OUT token is received when no
FIFO buffer planes are empty.
Note: This bit is provided for debugging. The system
should be designed so that no
overrun/underrun should occur.

Isochronous IN Buffer Flush
Specifies whether to flush the buffer when the pipe

isochronous IN transfers.
0: The buffer is not flushed.
1: The buffer is flushed.
When the function controller function is selected and the

interval set by the IITV bits in terms of () frames.
In double buffer mode (DBLB = 1), this module only
clears the data in the plane used earlier.
This module clears the FIFO buffer on receiving the SOF
packet immediately after the () frame in which this
module has expected to receive the IN token. Even if the
SOF packet is corrupted, this module also clears the
FIFO buffer at the right timing to receive the SOF packet
by using the internal interpolation.
When the host controller function is selected, set this bit

(1) When the pertinent pipe is for bulk IN transfer
(TYPE = 01 and DIR = 1)
When ATREPM = 1 and PID = BUF, this module
transmits a zero-length packet in response to the

This module updates (allows toggling of) the
sequence toggle bit (DATA-PID) each time this
module receives the ACK from the USB host (in a
single transaction, IN token is received, zerolength packet is transmitted, and then ACK is
received.).
In this case, this module does not generate the
BRDY or BEMP interrupt.
(2) When the pertinent pipe is for bulk OUT transfer
(TYPE = 01 and DIR = 0)
When ATREPM = 1 and PID = BUF, this module
returns NAK in response to the OUT (or PING)
token and generates the NRDY interrupt.
Modify this bit while CSSTS is 0 and PID is NAK.
Before modifying this bit after modifying the PID bits
for the corresponding pipe from BUF to NAK, check
that CSSTS and PBUSY are 0. However, if the PID
bits have been modified to NAK by this module,
checking PBUSY is not necessary.

SH7262 Group, SH7264 Group
This section describes the register operations that are necessary to the initial settings of this
module, and the registers necessary for power consumption control.

Table 26.15 lists the types of controller resets. For the initialized states of the registers following
the reset operations, see section 26.3, Register Description.

(2)
Controller Function Selection
This module can select the host controller function or function controller function using the
DCFM bit in SYSCFG. Changing the DCFM bit should be done in the initial settings immediately
after a power-on reset or in the D+ pull-up disabled (DPRPU = 0) and D + /D pull-down
disabled (DRPD = 0) state.
(3)
Enabling High-Speed Operation
This module can select a USB communication speed (communication bit rate). When the host
controller function is selected, the high-speed operation or full-speed/low-speed operation can be
set. When the function controller function is selected, either the high-speed operation or full-speed
operation can be selected. In order to enable the high-speed operation for this module, the HSE bit
in SYSCFG should be set to 1. If high-speed mode has been enabled, this module executes the
reset handshake protocol, and the USB communication speed is set automatically. The results of
the reset handshake can be confirmed using the RHST bit in DVSTCTR.
If high-speed operation has been disabled, this module operates at full-speed or low-speed. If the
function controller function is also selected, this module operates at full-speed.
Changing the HSE bit should be done between the ATTCH interrupt detection and bus reset
execution when the host controller function is selected, or with the D+ line pull-up disabled
(DPRPU = 0) when the host controller function is selected.

Section 26 USB 2.0 Host/Function Module
USB Data Bus Resistor Control
Figure 26.1 shows a diagram of the connections between this module and the USB connectors.
This module incorporates a pull-up resistor for the D+ signal and a pull-down resistor for the D+
and D- signals. These signals can be pulled up or down using the DPRPU and DRPD bits in
SYSCFG.
When the function controller function is selected, set the DPRPU bit in the SYSCFG register to 1
and pull up the D+ signal after recognizing a connection to the USB host. When disconnection of
the USB host is recognized, manipulate the DPRPU and DCFM bits as follows:
(1) Clear the DPRPU bit to 0.
(2) Wait a minimum of 1 µs.
(3) Set the DCFM bit to 1.
(4) Wait a minimum of 200 ns.
(5) Clear the DCFM bit to 0.
This module controls the terminal resistor for the D+ and D- signals during high-speed operation
and the output resistor for the signals during full-speed operation. This module automatically
switches the resistor after connection with the host controller or peripheral device by means of
reset handshake, suspended state and resume detection.
When the function controller function is selected and the DPRPU bit in SYSCFG is cleared to 0
during communication with the host controller, the pull-up resistor (or the terminal resistor) of the
USB data line is disabled, making it possible to notify the USB host of the device disconnection.

Section 26 USB 2.0 Host/Function Module
Register Access Wait Control
There is a restriction on the cycle time for accessing the registers of this module except for
SYSSTS as given below.
Wait-related restriction: The cycle time for successive accesses to the USB 2.0 host/function
module must be a duration of at least four USB clock (48 MHz) cycles (83.33 ns). To fulfill the
above restriction, a register access wait control is necessary using the BWAIT[3:0] bits in
BUSWAIT. The initial value is the maximum value (access cycles = 17 clock cycles). The
optimum value should be found and set.
Setting example 1: When successively accessing the registers of this module
Bus clock frequency: 72 MHz
Calculation: (2 cycles (access cycles for the registers of this module) + 1 cycle (interval between
successive accesses) + BWAIT) 1/72 MHz 83.33 ns
BWAIT = 3
Setting example 2: When sending data from the on-chip high-speed RAM to the FIFO port register
through DMA transfer
Bus clock frequency: 72 MHz
Calculation: (2 cycles (access cycles for the registers of this module) + 2 cycles (access cycles for
the on-chip high-speed RAM) + BWAIT) 1/72 MHz 83.33 ns
BWAIT = 2

Section 26 USB 2.0 Host/Function Module
BRDY Interrupt
The BRDY interrupt is generated when either of the host controller function or function controller
function is selected. The following shows the conditions under which this module sets 1 to a
corresponding bit in BRDYSTS. Under this condition, this module generates BRDY interrupt, if
the PIPEBRDYE bit in BRDYENB that corresponds to the pipe to 1 and the BRDYE bit in
INTENB0 have been set to 1.
The conditions for generating and clearing the BRDY interrupt depend on the settings of the
BRDYM bit and BFRE bit for the pertinent pipe as described below.
(a)
When the BRDYM bit is 0 and BFRE bit is 0
With these settings, the BRDY interrupt indicates that the FIFO port is accessible.
On any of the following conditions, this module generates the internal BRDY interrupt request
trigger and sets 1 to the PIPEBRDY bit corresponding to the pertinent pipe.
(i)
For the pipe in the transmitting direction:
When the DIR bit is changed from 0 to 1.
When packet transmission is completed using the pertinent pipe when write-access from
the CPU to the FIFO buffer for the pertinent pipe is disabled (when the BSTS bit is read as
0).
In continuous transmission/reception mode, the request trigger is generated on completion
of transmitting data of one plane of the FIFO buffer.
When one FIFO buffer is empty on completion of writing data to the other FIFO buffer in
double buffer mode.
The request trigger is not generated until completion of writing data to the currently-written
FIFO buffer plane even if transmission to the other FIFO buffer is completed.
When the hardware flushes the buffer of the pipe for isochronous transfers.
When 1 is written to the ACLRM bit, which causes the FIFO buffer to make transition
from the write-disabled to write-enabled state.
The request trigger is not generated for the DCP (that is, during data transmission for control
transfers).

Sep 24, 2014
Page 1481 of 2108
Section 26 USB 2.0 Host/Function Module
(ii)
SH7262 Group, SH7264 Group
For the pipe in the receiving direction:
When packet reception is completed successfully thus enabling the FIFO buffer to be read
when read-access from the CPU to the FIFO buffer for the pertinent pipe is disabled (when
the BSTS bit is read as 0).
The request trigger is not generated for the transaction in which DATA-PID disagreement
occurs.
In continuous transmission/reception mode, the request trigger is not generated when the
data is of the specified maximum packet size and the buffer has available space.
When a short packet is received, the request trigger is generated even if the FIFO buffer
has available space.
When the transaction counter is used, the request trigger is generated on receiving the
specified number of packets. In this case, the request trigger is generated even if the FIFO
buffer has available space.
When one FIFO buffer is read-enabled on completion of reading data from the other FIFO
buffer in double buffer mode.
The request trigger is not generated until completion of reading data from the currentlyread FIFO buffer plane even if reception by the other FIFO buffer is completed.
When the function controller function is selected, the BRDY interrupt is not generated in the
status stage of control transfers.
The PIPEBRDY interrupt status of the pertinent pipe can be cleared to 0 by writing 0 to the
corresponding PIPEBRDY interrupt status bit in the BRDYSTS register. In this case, 1s should be
written to the PIPEBRDY interrupt status bits for the other pipes.
Be sure to clear the BRDY status before accessing the FIFO buffer.

Section 26 USB 2.0 Host/Function Module
When the BRDYM bit is 0 and the BFRE bit is 1
With these settings, this module generates the BRDY interrupt on completion of reading all the
data for a single transfer using the pipe in the receiving direction, and sets 1 to the PIPEBRDY bit
corresponding to the pertinent pipe.
On any of the following conditions, this module determines that the last data for a single transfer
has been received.
When a short packet including a zero-length packet is received.
When the transaction counter register (TRNCNT bits) is used and the number of packets
specified by the TRNCNT bits are completely received.
When the pertinent data is completely read out after any of the above determination conditions has
been satisfied, this module determines that all the data for a single transfer has been completely
read out.
When a zero-length packet is received while the FIFO buffer is empty, the USB 2.0 host/function
module determines that all the data for a single transfer has been read at the point at which the
FRDY bit is set to 1 and the DTLN bit cleared to 0 in the FIFO port control register. In this case,
to start the next transfer, write 1 to the BCLR bit in the corresponding FIFOCTR register.
With these settings, this module does not detect the BRDY interrupt for the pipe in the
transmitting direction.
The PIPEBRDY interrupt status of the pertinent pipe can be cleared to 0 by writing 0 to the
corresponding PIPEBRDY interrupt status bit. In this case, 1s should be written to the PIPEBRDY
interrupt status bits for the other pipes.
In this mode, the BFRE bit setting should not be modified until all the data for a single transfer has
been processed. When it is necessary to modify the BFRE bit before completion of processing, all
the FIFO buffers for the pertinent pipe should be cleared using the ACLRM bit.

depending on the FIFO buffer status.

The BRDY interrupt status bits are set to 1 when the FIFO buffer is write-enabled and are set to 0
when write-disabled.
However, the BRDY interrupt is not generated if the DCP in the transmitting direction is writeenabled.
(ii)
For the pipe in the receiving direction:
The BRDY interrupt status bits are set to 1 when the FIFO buffer is read-enabled and are set to 0
when all the data have been read (read-disabled).
When a zero-length packet is received when the FIFO buffer is empty, the pertinent bit is set to 1
and the BRDY interrupt is continuously generated until BCLR = 1 is written. With this setting, the
PIPEBRDY bit cannot be cleared to 0. When BRDYM is set to 1, all of the BFRE bits (for all
pipes) should be cleared to 0.

NRDY Interrupt
On generating the internal NRDY interrupt request for the pipe whose PID bits are set to BUF,
this module sets the corresponding PIPENRDY bit in NRDYSTS to 1. If the corresponding bit in
NRDYENB is set to 1, this module sets the NRDY bit in INTSTS0 to 1, allowing the USB
interrupt to be generated.
The following describes the conditions on which this module generates the internal NRDY
interrupt request for a given pipe.
However, the internal NRDY interrupt request is not generated during setup transaction execution
when the host controller function is selected. During setup transactions when the host controller
function is selected, the SACK or SIGN interrupt is detected.
The internal NRDY interrupt request is not generated during status stage execution of the control
transfer when the function controller function is selected.

no split transactions occur
For the pipe in the transmitting direction:
On any of the following conditions, this module detects the NRDY interrupt.
For the pipe for isochronous transfers, when the time to issue an OUT token comes in a
state in which there is no data to be transmitted in the FIFO buffer.
In this case, this module transmits a zero-length packet following the OUT token, setting
the corresponding PIPENRDY bit and the OVRN bit to 1.
During communications other than setup transactions using the pipe for the transfers other
than isochronous transfers, when any combination of the following two cases occur three
consecutive times: 1) no response is returned from the peripheral device (when timeout is
detected before detection of the handshake packet from the peripheral device) and 2) an
error is detected in the packet from the peripheral device.
In this case, this module sets the corresponding PIPENRDY bit to 1 and modifies the
setting of the PID bits of the corresponding pipe to NAK.
During communications other than setup transactions, when the STALL handshake is
received from the peripheral device (including the STALL handshake in response to PING
in addition to the STALL handshake in response to OUT).
In this case, this module sets the corresponding PIPENRDY bit to 1 and modifies the
setting of the PID bits of the corresponding pipe to STALL (11).

BEMP Interrupt
On generating the BEMP interrupt for the pipe whose PID bits are set to BUF, this module sets the
corresponding PIPEBEMP bit in BEMPSTS to 1. If the corresponding bit in BEMPENB is set to
1, this module sets the BEMP bit in INTSTS0 to 1, allowing the USB interrupt to be generated.
The following describes the conditions on which this module generates the internal BEMP
interrupt request.
(a) For the pipe in the transmitting direction, when the FIFO buffer of the corresponding pipe is
empty on completion of transmission (including zero-length packet transmission). In single
buffer mode, the internal BEMP interrupt request is generated simultaneously with the
BRDY interrupt for the pipe other than DCP. However, the internal BEMP interrupt request
is not generated on any of the following conditions.
When writing data to the FIFO buffer of the CPU has already been started on completion
of transmitting data of one plane in double buffer mode.
When the buffer is cleared (emptied) by setting the ACLRM or BCLR bit to 1.
When IN transfer (zero-length packet transmission) is performed during the control transfer
status stage in function controller mode.
(b) For the pipe in the receiving direction:
When the successfully-received data packet size exceeds the specified maximum packet size.
In this case, this module generates the BEMP interrupt request, setting the corresponding
PIPEBEMP bit to 1, and discards the received data and modifies the setting of the PID bits of
the corresponding pipe to STALL (11).
Here, this module returns no response when used as the host controller, and returns STALL
response when used as the function controller.
However, the internal BEMP interrupt request is not generated on any of the following
conditions.
When a CRC error or bit stuffing error is detected in the received data.
When a setup transaction is being performed. Writing 0 to the PIPEBEMP bit clears the
status; writing 1 to the PIPEBEMP bit has no effect.

Device State Transition Interrupt
Figure 26.6 shows a diagram of this module device state transitions. This module controls device
states and generates device state transition interrupts. However, recovery from the suspended state
(resume signal detection) is detected by means of the resume interrupt. The device state transition
interrupts can be enabled or disabled individually using INTENB0. The device state that made a
transition can be confirmed using the DVSQ bit in INTSTS0.
To make a transition to the default state, the device state transition interrupt is generated after the
reset handshake protocol has been completed.
Device state can be controlled only when the function controller function is selected. Also, the
device state transition interrupts can be generated only when the function controller function is
selected.

Control Transfer Stage Transition Interrupt (Function Controller Function)
Figure 26.7 shows a diagram of how this module handles the control transfer stage transition. This
module controls the control transfer sequence and generates control transfer stage transition
interrupts. Control transfer stage transition interrupts can be enabled or disabled individually using
INTENB0. The transfer stage that made a transition can be confirmed using the CTSQ bit in
INTSTS0.
The control transfer stage transition interrupts are generated only when the function controller
function is selected.
The control transfer sequence errors are described below. If an error occurs, the PID bit in
DCPCTR is set to B'1x (STALL).
(a)
During control read transfers
At the IN token of the data stage, an OUT or PING token is received when there have been
no data transfers at all.
An IN token is received at the status stage
A packet is received at the status stage for which the data packet is DATAPID = DATA0
(b)
During control write transfers
At the OUT token of the data stage, an IN token is received when there have been no ACK
response at all
A packet is received at the data stage for which the first data packet is DATAPID =
DATA0
At the status stage, an OUT or PING token is received
(c)
During no-data control transfers
At the status stage, an OUT or PING token is received
At the control write transfer stage, if the number of receive data exceeds the wLength value of the
USB request, it cannot be recognized as a control transfer sequence error. At the control read
transfer status stage, packets other than zero-length packets are received by an ACK response and
the transfer ends normally.
When a CTRT interrupt occurs in response to a sequence error, the CTSQ = 110 value is retained
until CTRT = 0 is written from the system (the interrupt status is cleared). Therefore, while CTSQ
= 110 is being held, the CTRT interrupt that ends the setup stage will not be generated even if a
new USB request is received. (The USB 2.0 host/function module retains the setting of the CTSQ

Frame Update Interrupt
Figure 26.8 shows an example of the SOFR interrupt output timing of this module. With the host
controller function selected, an interrupt is generated at the timing at which the frame number is
updated. With the function controller function selected, the SOFR interrupt is generated when the
frame number is updated.
When the function controller function is selected, this module updates the frame number and
generates an SOFR interrupt if it detects a new SOF packet during full-speed operation. During
high-speed operation, however, this module does not update the frame number, or generates no
SOFR interrupt until the module enters the SOF locked state. Also, the SOF interpolation
function is not activated. The SOF lock state is the state in which SOF packets with different
frame numbers are received twice continuously without error occurrence.
The conditions under which the SOF lock monitoring begins and stops are as follows.

VBUS Interrupt
If there has been a change in the VBUS pin, the VBUS interrupt is generated. The level of the
VBUS pin can be checked with the VBSTS bit in INTSTS0. Whether the host controller is
connected or disconnected can be confirmed using the VBUS interrupt. However, if the system is
activated with the host controller connected, the first VBUS interrupt is not generated because
there is no change in the VBUS pin.
(8)
Resume Interrupt
With the function controller function selected, the resume interrupt is generated when the USB bus
state changes (from J-state to K-state, or from J-state to SE0) while the device state is the
suspended state.. Recovery from the suspended state is detected by means of the resume interrupt.
With the host controller function selected, the resume interrupt is not generated; use the BCHG
interrupt to detect the change of the USB bus state.

BCHG Interrupt
The BCHG interrupt is generated when the USB bus state has changed. The BCHG interrupt can
be used to detect whether or not the peripheral device is connected when the host controller
function has been selected and can also be used to detect a remote wakeup. The BCHG interrupt is
generated regardless of whether the host controller function or function controller function has
been selected.
(10) DTCH Interrupt
The DTCH interrupt is generated if disconnection of the USB bus is detected when the host
controller function has been selected. This module detects bus disconnection based on USB
Specification 2.0.
After detecting the DTCH interrupt, this module controls hardware as described below
(irrespective of the set value of the corresponding interrupt enable bit). Terminate all the pipes in
which communications are currently carried out for the USB port and make a transition to the wait
state for bus connection to the USB port (wait state for ATTCH interrupt generation).
(a) Modifies the UACT bit to 0.
(b) Puts the port into the idle state.
(11) SACK Interrupt
The SACK interrupt is generated when an ACK response for the transmitted setup packet has been
received from the peripheral device with the host controller function selected. The SACK interrupt
can be used to confirm that the setup transaction has been completed successfully.
(12) SIGN Interrupt
The SIGN interrupt is generated when an ACK response for the transmitted setup packet has not
been correctly received from the peripheral device three consecutive times with the host controller
function selected. The SIGN interrupt can be used to detect no ACK response transmitted from the
peripheral device or corruption of an ACK packet.

(13) ATTCH Interrupt
The ATTCH interrupt is generated when J-state or K-state of the full-speed or low-speed level
signal is detected on the USB port for 2.5 s in host controller mode. To be more specific, the
ATTCH interrupt is detected on any of the following conditions.
(a) When K-state, SE0, or SE1 changes to J-state, and J-state continues 2.5 s.
(b) When J-state, SE0, or SE1 changes to K-state, and K-state continues 2.5 s.

The EOFERR interrupt is generated when it is detected that communication is not completed at
the EOF2 timing prescribed by USB Specification 2.0.
After detecting the EOFERR interrupt, this module controls hardware as described below
(irrespective of the set value of the corresponding interrupt enable bit). Terminate all the pipes in
which communications are currently carried out for the pertinent port and perform re-enumeration
of the pertinent port.
(a) Modifies the UACT bit for the port in which an EOFERR interrupt has been detected to 0.
(b) Puts the port in which an EOFERR interrupt has been generated into the idle state.

Pipe Control
Table 26.17 lists the pipe setting items of this module. With USB data transfer, data transmission
has to be carried out using the logic pipe called the endpoint. This module has ten pipes that are
used for data transfer.
Settings should be entered for each of the pipes in conjunction with the specifications of the
system.

supported.
(5)
Transaction Counter (For PIPE1 to PIPE5 in Reading Direction)
When the specified number of transactions have been completed in the data packet receiving
direction, this module recognizes that the transfer has ended. The transaction counter function is
available when the pipes assigned to the D0FIFO/D1FIFO port have been set in the direction of
reading data from the buffer memory. Two transaction counters are provided: one is the TRNCNT
register that specifies the number of transactions to be executed and the other is the current
counter that internally counts the number of executed transactions. When the current counter value
matches the number of the transactions specified in TRNCNT, reading the buffer memory is
enabled. The current counter of the transaction counter function is initialized by the TRCLR bit, so
that the transactions can be counted again starting from the beginning. The information read from
TRNCNT differs depending on the setting of the TRENB bit.
TRENB = 0: The specified transaction counter value can be read.
TRENB = 1: The current counter value indicating the internally counted number of executed
transactions can be read.
When operating the TRCLR bit, the following should be noted.
If the transactions are being counted and PID = BUF, the current counter cannot be cleared.
If there is any data left in the buffer, the current counter cannot be cleared.

Response PID
The PID bits in DCPCTR and PIPEnCTR are used to set the response PID for each pipe.
The following shows this module operation with various response PID settings:
(a)
Response PID settings when the host controller function is selected
The response PID is used to specify the execution of transactions.
NAK setting: Using pipes is disabled. No transaction is executed.
BUF setting: Transactions are executed based on the status of the buffer memory. For OUT
direction: If there are transmit data in the buffer memory, an OUT token is issued.
For IN direction: If there is an area to receive data in the buffer memory, an IN token is issued.
STALL setting: Using pipes is disabled. No transaction is executed.
Setup transactions for the DCP are set with the SUREQ bit.
(b)
Response PID settings when the function controller function is selected
The response PID is used to specify the response to transactions from the host.
NAK setting: The NAK response is always returned in response to the generated transaction.
BUF setting: Responses are made to transactions based on the status of the buffer memory.
STALL setting: The STALL response is always returned in response to the generated
transaction.
For setup transactions, an ACK response is always returned, regardless of the PID setting, and the
USB request is stored in the register.
This module may carry out writing to the PID bits, depending on the results of the transaction.
(a)
When the host controller function has been selected and the response PID is set by
hardware
NAK setting: In the following cases, PID = NAK is set and issuing of tokens is automatically
stopped:
When, during a transfer other than isochronous transfer, three receive errors such as no
response, bit stuffing error, or CRC error are returned in succession after token
transmission.
When, during isochronous transfer, three receive errors such bit stuffing error or CRC error
are returned in succession after token transmission.

Section 26 USB 2.0 Host/Function Module
Data PID Sequence Bit
This module automatically toggles the sequence bit in the data PID when data is transferred
normally in the control transfer data stage, bulk transfer and interrupt transfer. The sequence bit of
the data PID that was transmitted can be confirmed with the SQMON bit in DCPCTR and
PIPEnCTR. When data is transmitted, the sequence bit switches at the timing at which the ACK
handshake is received. When data is received, the sequence bit switches at the timing at which the
ACK handshake is transmitted. The SQCLR bit in DCPCTR and the SQSET bit in PIPEnCTR can
be used to change the data PID sequence bit.
When the function controller function has been selected and control transfer is used, this module
automatically sets the sequence bit when a stage transition is made. The bit is set to DATA1 when
the setup stage ends. In the status stage, DATA1 is returned without referencing the sequence bit.
Therefore, settings are not required. However, when the host controller function has been selected
and control transfer is used, the sequence bit should be set at the stage transition.
For the Clearfeature request transmission or reception, the data PID sequence bit should be set,
regardless of whether the host controller function or function controller function is selected.
With pipes for which isochronous transfer has been set, sequence bit operation cannot be carried
out using the SQSET bit.
(8)
Response PID = NAK Function
This module has a function that disables pipe operation (PID response = NAK) at the timing at
which the final data packet of a transaction is received (this module automatically distinguishes
this based on reception of a short packet or the transaction counter) by setting the SHTNAK bit in
PIPECFG to 1.
When a double buffer is being used for the buffer memory, using this function enables reception
of data packets in transfer units. If pipe operation has disabled, the pipe has to be set to the enabled
state again (PID response = BUF).
This function can be used only when bulk transfers are used.

Auto Transfer MODE
With the pipes for bulk transfer (PIPE1 to PIPE5), when the ATREPM bit in PIPEnCTR is set to
1, a transition is made to auto response mode. During an OUT transfer (DIR = 0), OUT-NAK
mode is entered, and during an IN transfer (DIR = 1), null auto response mode is entered.
(a)
OUT-NAK Mode
With the pipes for bulk OUT transfer, NAK is returned in response to an OUT or PING token and
an NRDY interrupt is output when the ATREPM bit is set to 1. To make a transition from normal
mode to OUT-NAK mode, OUT-NAK mode should be specified in the pipe operation disabled
state (response PID = NAK) before enabling pipe operation (response PID = BUF). After pipe
operation has been enabled, OUT-NAK mode becomes valid. However, if an OUT token is
received immediately before pipe operation is disabled, the token data is normally received, and
an ACK is retuned to the host.
To make a transition from OUT-NAK mode to normal mode, OUT-NAK mode should be
canceled in the pipe operation disabled state (response PID = NAK) before enabling pipe
operation (response PID = BUF). In normal mode, reception of OUT data is enabled and an ACK
is returned in response to a PING token if the buffer is ready to receive data.
(b)
Null Auto Response Mode
With the pipes for bulk IN transfer, zero-length packets are continuously transmitted when the
ATREPM bit is set to 1.
To make a transition from normal mode to null auto response mode, null auto response mode
should be set in the pipe operation disabled state (response PID = NAK) before enabling pipe
operation (response PID = BUF). After pipe operation has been enabled, null auto response mode
becomes valid. Before setting null auto response mode, INBUFM = 0 should be confirmed
because the mode can be set only when the buffer is empty. If the INBUFM bit is 1, the buffer
should be emptied with the ACLRM bit. While a transition to null auto response mode is being
made, data should not be written from the FIFO port.
To make a transition from null auto response mode to normal mode, pipe operation disabled state
(response PID = NAK) should be retained for the period of zero-length packet transmission (fullspeed: 10 s, high-speed: 3 s) before canceling null auto response mode. In normal mode, data
can be written from the FIFO port; therefore, packet transmission to the host is enabled by
enabling pipe operation (response PID = BUF).

FIFO Buffer Memory
FIFO Buffer Memory Allocation
Figure 26.9 shows an example of a FIFO buffer memory map for this module. The FIFO buffer
memory is an area shared by the CPU and this module. In the FIFO buffer memory status, there
are times when the access right to the buffer memory is allocated to the user system (CPU side),
and times when it is allocated to this module (SIE side).
The buffer memory sets independent areas for each pipe. In the memory areas, 64 bytes comprise
one block, and the memory areas are set using the first block number of the number of blocks
(specified using the BUFNMB and BUFSIZE bits in PIPEBUF).
Independent buffer memory areas should be set for each pipe. Each memory area can be set using
the first block number and the number of blocks (specified using the BUFNMB and BUFSIZE bits
in PIPEBUF), where one block comprises 64 bytes.
When continuous transfer mode has been selected using the CNTMD bit in PIPECFG, the
BUFSIZE bits should be set so that the buffer memory size should be an integral multiple of the
maximum packet size. When double buffer mode has been selected using the DBLB bit in
PIPECFG, two planes of the memory area specified using the BUFSIZE bits in PIPEBUF can be
assigned to a single pipe.
Moreover, three FIFO ports are used for access to the buffer memory (reading and writing data). A
pipe is assigned to the FIFO port by specifying the pipe number using the CURPIPE bit in
C/DnFIFOSEL.
The buffer statuses of the various pipes can be confirmed using the BSTS bit in DCPCTR and the
INBUFM bit in PIPEnCTR. Also, the access right of the FIFO port can be confirmed using the
FRDY bit in CFIFOCTR or DnFIFOCTR.

Buffer Status
Tables 26.18 and 26.19 show the buffer status. The buffer memory status can be confirmed using
the BSTS bit in DCPCTR and the INBUFM bit in PIPEnCTR. The access direction for the buffer
memory can be specified using either the DIR bit in PIPECFG or the ISEL bit in CFIFOSEL
(when DCP is selected).
The INBUFM bit is valid for PIPE0 to PIPE5 in the sending direction.
For an IN pipe uses double buffer, the BSTS bit can be used to monitor the buffer memory status
of CPU side and the INBUFM bit to monitor the buffer memory status of SIE side. In the case like
the BEMP interrupt may not shows the buffer empty status because the CPU (direct memory
access controller) writes data slowly, the INBUFM bit can be used to confirm the end of sending.

Buffer Areas
Table 26.21 shows the FIFO buffer memory map of this controller. The buffer memory has special
fixed areas to which pipes are assigned in advance, and user areas that can be set by the user.
The buffer for the DCP is a special fixed area that is used both for control read transfers and
control write transfers.
The PIPE6 to PIPE9 area is assigned in advance, but the area for pipes that are not being used can
be assigned to PIPE1 to PIPE5 as a user area.
The settings should ensure that the various pipes do not overlap. Note that each area is twice as
large as the setting value in the double buffer.
Also, the buffer size should not be specified using a value that is less than the maximum packet
size.

Auto Buffer Clear Mode Function
With this module, all of the received data packets are discarded if the ACLRM bit in PIPEnCTR is
set to 1. If a normal data packet has been received, the ACK response is returned to the host
controller. This function can be set only in the buffer memory reading direction.
Also, if the ACLRM bit is set to 1 and then to 0, the buffer memory of the selected pipe can be
cleared regardless of the access direction.

Buffer Memory Specifications (Single/Double Setting)
Either a single or double buffer can be selected for PIPE1 to PIPE5, using the DBLB bit in
PIPECFG. The double buffer is a function that assigns two memory areas specified with the
BUFSIZE bit in PIPEBUF to the same pipe. Figure 26.10 shows an example of buffer memory
settings for this module.

Buffer Memory Operation (Continuous Transfer Setting)
Either the continuous transfer mode or the non-continuous transfer mode can be selected, using the
CNTMD bit in DCPCFG and PIPECFG. This selection is valid for PIPE1 to PIPE5 and DCP.
The continuous transfer mode function is a function that sends and receives multiple transactions
in succession. When the continuous transfer mode is set, data can be transferred without interrupts
being issued to the CPU, up to the buffer sizes assigned for each of the pipes.
In the continuous sending mode, the data being written is divided into packets of the maximum
packet size and sent. If the data being sent is less than the buffer size (short packet, or the integer
multiple of the maximum packet size is less than the buffer size), BVAL = 1 must be set after the
data being sent has been written.
In the continuous reception mode, interrupts are not issued during reception of packets up to the
buffer size, until the transaction counter has ended, or a short packet is received.
Table 26.22 describes the relationship between the transfer mode settings by CNTMD bit and the
timings at which reading data or transmitting data from the FIFO buffer is enabled.

FIFO Port Functions
Table 26.23 shows the settings for the FIFO port functions of this module. In write access, writing
data until the buffer is full (or the maximum packet size for non-continuous transfers)
automatically enables sending of the data. To enable sending of data before the buffer is full (or
before the maximum packet size for non-continuous transfers), the BVAL bit in C/DnFIFOCTR
must be set to end the writing. Also, to send a zero-length packet, the BCLR bit in the same
register must be used to clear the buffer and then the BVAL bit set in order to end the writing.
In read access, reception of new packets is automatically enabled if all of the data has been read.
Data cannot be read when a zero-length packet is being received (DTLN = 0), so the BCLR bit in
the register must be used to release the buffer. The length of the data being received can be
confirmed using the DTLN bit in C/DnFIFOCTR.

FIFO Port Selection
Table 26.24 shows the pipes that can be selected with the various FIFO ports. The pipe to be
accessed is selected using the CURPIPE bit in C/DnFIFOSEL. After the pipe is selected, whether
the CURPIPE value for the pipe, which was written last, can be correctly read should be checked.
(If the previous pipe number is read, it indicates that the pipe modification is being executed by
this module.) Then, the FIFO port can be accessed after FRDY = 1 is checked .
Also, the bus width to be accessed should be selected using the MBW bit. The buffer memory
access direction conforms to the DIR bit in PIPECFG. The ISEL bit determines this only for the
DCP.

REW Bit
It is possible to temporarily stop access to the pipe currently being accessed, access a different
pipe, and then continue processing using the current pipe once again. The REW bit in
C/DnFIFOSEL is used for this.
If a pipe is selected when the REW bit is set to 1 and at the same time the CURPIPE bit in
C/DnFIFOSEL is set, the pointer used for reading from and writing to the buffer memory is reset,
and reading or writing can be carried out from the first byte. Also, if a pipe is selected with 0 set
for the REW bit, data can be read and written in continuation of the previous selection, without the
pointer used for reading from and writing to the buffer memory being reset.
To access the FIFO port, FRDY = 1 must be ensured after selecting a pipe.

Accessing FIFO Port for Odd Data
For reading data from the FIFO port, when the number of data bits to be read is smaller than the
access width specified by the MBW bits in the FIFO port select registers, read the data with the
specified width and discard the unnecessary bits through software.
For writing data to the FIFO port, when the number of data bits to be written is smaller than the
access width specified by the MBW bits in the FIFO port select registers, access the registers as
shown in the following examples. In the examples, the FIFO port access width is 32 bits (MBW =
10) and 24-bit data is written to the FIFO port.

Modifying MBW Bits when the Pipe is in the Receiving Direction
When the specified pipe is in the receiving direction, modify the MBW bits in the FIFO port select
registers (CFIFOSEL, D0FIFOSEL, D1FIFOSEL) simultaneously with the CURPIPE bits. When
the DCP is currently set (CURPIPE = 000) in the CFIFO port select register, modify the MBW
bits simultaneously with the CURPIPE bits or ISEL bit.
To modify only the MBW bits for the currently set pipe, follow the procedure below. Once the
buffer memory starts to be read out, however, do not modify the MBW bits until the entire data
has been read out.
When the selected CURPIPE is in the writing direction to buffer memory, the port access width
can be changed simply by setting the MBW bits.
Once the buffer memory starts to be written to, however, do not modify the port access width from
8 bits to 16 or 32 bits, or from16 bits to 32 bits.

DMA Transfers (D0FIFO/D1FIFO Port)
(a)
Overview of DMA Transfers
For pipes 1 to 9, the FIFO port can be accessed using the direct memory access controller. When
accessing the buffer for the pipe targeted for DMA transfer is enabled, a DMA transfer request is
issued.
The unit of transfer to the FIFO port should be selected using the MBW bit in DnFIFOSEL and
the pipe targeted for the DMA transfer should be selected using the CURPIPE bit. The selected
pipe should not be changed during the DMA transfer.
(b)
Auto Recognition of DMA Transfer Completion
With this module, it is possible to complete FIFO data writing through DMA transfer by
controlling DMA transfer end signal input. The DMA transfer end signal is output from the direct
memory access controller when the controller transfers data through DMA for the times specified
by the DMA transfer count register (DMATCR) of the direct memory access controller. When a
transfer end signal is sampled, the module enables buffer memory transmission (the same

condition as when BVAL = 1). Whether to sample the DMA transfer end signal can be specified
through the TENDE bit in DnFBCFG.
Note that this function cannot be used when the DMA transfer size is set to 16 bytes.
(c)
DnFIFO Auto Clear Mode (D0FIFO/D1FIFO Port Reading Direction)
If 1 is set for the DCLRM bit in DnFIFOSEL, the module automatically clears the buffer memory
of the selected pipe when reading of the data from the buffer memory has been completed.
Table 26.25 shows the packet reception and buffer memory clearing processing for each of the
various settings. As shown, the buffer clear conditions depend on the value set to the BFRE bit.
Using the DCLRM bit eliminates the need for the buffer to be cleared even if a situation occurs
that necessitates clearing of the buffer. This makes it possible to carry out DMA transfers without
involving software.
This function can be set only in the buffer memory reading direction.

Control Transfers (DCP)
Data transfers of the data stage of control transfers are done using the default control pipe (DCP).
The DCP buffer memory is a 256-byte single buffer, and is a fixed area that is shared for both
control reading and control writing. The buffer memory can be accessed through the CFIFO port.
(1)
Control Transfers when the Host Controller Function is Selected
(a)
Setup Stage
USQREQ, USBVAL, USBINDX, and USBLENG are the registers that are used to transmit a USB
request for setup transactions. Writing setup packet data to the registers and writing 1 to the
SUREQ bit in DCPCTR transmits the specified data for setup transactions. Upon completion of
transactions, the SUREQ bit is cleared to 0. The above USB request registers should not be
modified while SUREQ = 1. The device address for setup transactions is specified using the
DEVSEL bits in DCPMAXP.
When the data for setup transactions has been sent, a SIGN or SACK interrupt request is generated
according to the response received from the peripheral device (SIGN1 or SACK bits in INTSTS1),
by means of which the result of the setup transactions can be confirmed.
A data packet of DATA0 (USB request) is transmitted as the data packet for the setup transactions
regardless of the setting of the SQMON bit in DCPCTR.
(b)
Data Stage
Data transfers are done using the DCP buffer memory.
The access direction of the DCP buffer memory should be specified using the ISEL bit in
CFIFOSEL. Also specify the transfer direction using the DIR bit in the DCPCFG register.
For the first data packet of the data stage, the data PID must be transferred as DATA1. Transaction
is done by setting the data PID = DATA1 and the PID bit = BUF using the SQSET bit in
DCPCTR. Completion of data transfer is detected using the BRDY or BEMP interrupts.
Setting continuous transfer mode allows data transfers over multiple packets. Note that when
continuous transfer mode is set for the receiving direction, the BRDY interrupt is not generated
until the buffer becomes full or a short packet is received (the integer multiple of the maximum
packet size, and less than 256 bytes).
For control write transfers, when the number of data bytes to be sent is the integer multiple of the
maximum packet size, a zero-length packet must be controlled to be sent at the end.

Section 26 USB 2.0 Host/Function Module
Status Stage
Zero-length packet data transfers are done in the direction opposite to that in the data stage. As
with the data stage, data transfers are done using the DCP buffer memory. Transactions are done
in the same manner as the data stage.
For the data packets of the status stage, the data PID must be transferred as DATA1. The data PID
should be set to DATA1 using the SQSET bit in DCPCTR.
For reception of a zero-length packet, the received data length must be confirmed using the DTLN
bits in CFIFOCTR after the BRDY interrupt is generated, and the buffer memory must then be
cleared using the BCLR bit.
(2)
Control Transfers when the Function Controller Function is Selected
(a)
Setup Stage
This module always sends an ACK response in response to a setup packet that is normal with
respect to this module. The operation of this module operates in the setup stage is noted below.
(i)
When a new USB request is received, this module sets the following registers:
Set the VALID bit in INTSTS0 to 1.
Set the PID bit in DCPCTR to NAK.
Set the CCPL bit in DCPCTR to 0.
(ii) When a data packet is received right after the SETUP packet, the USB request parameters are
stored in USBREQ, USBVAL, USBINDX, and USBLENG.
Response processing with respect to the control transfer should always be carried out after first
setting VALID = 0. In the VALID = 1 state, PID = BUF cannot be set, and the data stage cannot
be terminated.
Using the function of the VALID bit, this module is able to interrupt the processing of a request
currently being processed if a new USB request is received during a control transfer, and can send
a response in response to the newest request.
Also, this module automatically judges the direction bit (bit 8 of the bmRequestType) and the
request data length (wLength) of the USB request that was received, and then distinguishes
between control read transfers, control write transfers, and no-data control transfers, and controls
the stage transition. For a wrong sequence, the sequence error of the control transfer stage
transition interrupt is generated, and the software is notified. For information on the stage control
of this module, see figure 26.7.

Section 26 USB 2.0 Host/Function Module
(b)
SH7262 Group, SH7264 Group
Data Stage
Data transfers corresponding to USB requests that have been received should be done using the
DCP. Before accessing the DCP buffer memory, the access direction should be specified using the
ISEL bit in CFIFOSEL.
A transaction is executed by setting the PID bits in the DCPCTR register to BUF. The BRDY
interrupt or the BEMP interrupt can be used to detect the end of data transfer. Use the BRDY
interrupt to detect the end of control write transfers and the BEMP interrupt to detect the end of
control read transfers.
With control write transfers during high-speed operation, the NYET handshake response is carried
out based on the state of the buffer memory.
(c)
Status Stage
Control transfers are terminated by setting the CCPL bit to 1 with the PID bit in DCPCTR set to
PID = BUF.
After the above settings have been entered, this module automatically executes the status stage in
accordance with the data transfer direction determined at the setup stage. The specific procedure is
as follows.
(i)
For control read transfers:
This module receives a zero-length packet from the USB host and sends an ACK response.
(ii)
For control write transfers and no-data control transfers:
This module sends the zero-length packet from the USB host and receives an ACK response.

Bulk Transfers (PIPE1 to PIPE5)
The buffer memory specifications for bulk transfers (single/double buffer setting, or
continuous/non-continuous transfer mode setting) can be selected. The maximum size that can be
set for the buffer memory is 2 Kbytes. The buffer memory state is controlled by this module, with
a response sent automatically for a PING packet/NYET handshake.
(1)
PING Packet Control when the Host Controller Function is Selected
This module automatically sends a PING packet in the OUT direction.
On receiving an ACK handshake in the initial state in which PING packet sending mode is set,
this module sends an OUT packet as noted below. The module returns to PING packet sending
mode when a NAK or NYET is received during an OUT transaction.
1. Sets OUT data sending mode.
2. Sends a PING packet.
3. Receives an ACK handshake.
4. Sends an OUT data packet.
5. Receives an ACK handshake.
(Repeats steps 4 and 5.)
6. Sends an OUT data packet.
7. Receives an NAK/NYET handshake.
8. Sends a PING packet.
This module is returned to PING packet sending mode by a power-on reset, receiving a
NYET/NAK handshake, clearing the sequence toggle bits (SQCLR), and setting the buffer clear
bit (ACLRM) in PIPEnCTR.

Interrupt Transfers (PIPE6 to PIPE9)
When the function controller function is selected, this module carries out interrupt transfers in
accordance with the timing controlled by the host controller. For interrupt transfers, PING packets
are ignored (no responses are sent), and the ACK, NAK, and STALL responses are carried out
without an NYET handshake response being made.
When the host controller function is selected, this module can set the timing of issuing a token
using the interval timer. At this time, this module issues an OUT token even in the OUT direction,
without issuing a PING token.
This module does not support high bandwidth transfers of interrupt transfers.

Interval Counter during Interrupt Transfers when the Host Controller Function is
Selected
For interrupt transfers, intervals between transactions are set in the IITV bits in PIPEPERI. This
controller issues an interrupt transfer token based on the specified intervals.
(a)
Counter Initialization
This controller initializes the interval counter under the following conditions.
Power-on reset
The IITV bits are initialized.
Buffer memory initialization using the ACLRM bit
The IITV bits are not initialized but the count value is. Setting the ACLRM bit to 0 starts
counting from the value set in the IITV bits.
Note that the interval counter is not initialized in the following case.
USB bus reset, USB suspended
The IITV bits are not initialized. Setting 1 to the UACT bit starts counting from the value
before entering the USB bus reset state or USB suspended state.

When the selected pipe is for isochronous transfers, this module carries out the operation below in
addition to controlling token issuance interval. This module issues a token even when the NRDY
interrupt generation condition is satisfied.
When the selected pipe is for isochronous IN transfers
This module generates the NRDY interrupt when this module issues the IN token but does not
receive a packet successfully from a peripheral device (no response or packet error).
This module sets the OVRN bit to 1 generating the NRDY interrupt when the time to issue an
IN token comes in a state in which this module cannot receive data because the FIFO buffer is
full (because data is read from the FIFO buffer too late).
When the selected pipe is for isochronous OUT transfers
This module sets the OVRN bit to 1 generating the NRDY interrupt and transmitting a zerolength packet when the time to issue an OUT token comes in a state in which there is no data
to be transmitted in the FIFO buffer (because data is written to the FIFO buffer too late ).
The token issuance interval is reset when a power-on reset is applied or the ACLRM bit is set
to 1.

This module generates the NRDY interrupt when this module fails to receive a data packet
because of a CRC error or other errors contained in the packet, or because of the FIFO buffer

This module generates the NRDY interrupt on receiving an SOF packet. Even if the SOF
packet is corrupted, the internal interpolation is used and allows the interrupt to be generated at
the timing to receive the SOF packet.
However, when the IITV bits are set to the value other than 0, this module generates the
NRDY interrupt on receiving an SOF packet for every interval after starting interval counting
operation. When the PID bits are set to NAK after starting the interval timer, this module does
not generate the NRDY interrupt on receiving an SOF packet.
The interval counting starts at the different timing depending on the IITV bit setting as

The IFIS bit should be 1 for this use. When IFIS = 0, this module transmits a data packet in
response to the received IN token irrespective of the IITV bit setting.
When IFIS = 1, this module clears the FIFO buffer when this module fails to receive an IN
token within the interval set by the IITV bits in terms of () frames in a state in which there is
data to be transmitted in the FIFO buffer.
This module also clears the FIFO buffer when this module fails to receive an IN token
successfully because of a bus error such as a CRC error contained in the token.
This module clears the FIFO buffer on receiving an SOF packet. Even if the SOF packet is
corrupted, the internal interpolation is used and allows the FIFO buffer to be cleared at the
timing to receive the SOF packet.
The interval counting starts at the different timing depending on the IITV bit setting (similar to
the timing during OUT transfers).

Setup of Data to be Transmitted using Isochronous Transfer when the Function
Controller Function is Selected
With isochronous data transmission using this module in function controller function, after data
has been written to the buffer memory, a data packet can be sent with the next frame in which an
SOF packet is detected. This function is called the isochronous transfer transmission data setup
function, and it makes it possible to designate the frame from which transmission began.
If a double buffer is used for the buffer memory, transmission will be enabled for only one of the
two buffers even after the writing of data to both buffers has been completed, that buffer memory
being the one to which the data writing was completed first. For this reason, even if multiple IN
tokens are received, the only buffer memory that can be sent is one packet's worth of data.
When an IN token is received, if the buffer memory is in the transmission enabled state, this
module transmits the data. If the buffer memory is not in the transmission enabled state, however,
a zero-length packet is sent and an underrun error occurs.
Figure 26.20 shows an example of transmission using the isochronous transfer transmission data
setup function with this module, when IITV = 0 (every frame) has been set.

Isochronous Transfer Transmission Buffer Flush when the Function Controller
Function is Selected
If an SOF packet or a SOF packet is received without receiving an IN token in the interval frame
during isochronous data transmission, this module operates as if an IN token had been corrupted,
and clears the buffer for which transmission is enabled, putting that buffer in the writing enabled
state.
If a double buffer is being used and writing to both buffers has been completed, the buffer
memory that was cleared is seen as the data having been sent at the same interval frame, and
transmission is enabled for the buffer memory that is not discarded with SOF or SOF packets
reception.

In any cases other than IITV = 0
The buffer flush operation is carried out subsequent to the first normal transaction.

Figure 26.22 shows an example of this module generating an interval error. There are five types of
interval errors, as shown below. The interval error is generated at the timing indicated by (1) in the
figure, and the IN buffer flush function is activated.
If an interval error occurs during an IN transfers, the buffer flush function is activated; and if it
occurs during an OUT transfer, an NRDY interrupt is generated.
The OVRN bit should be used to distinguish between NRDY interrupts such as received packet
errors and overrun errors.
In response to tokens that are shaded in the figure, responses occur based on the buffer memory
status.
1. IN direction:
If the buffer is in the transmission enabled state, the data is transferred as a normal
response.
If the buffer is in the transmission disabled state, a zero-length packet is sent and an
underrun error occurs.
2. OUT direction:
If the buffer is in the reception enabled state, the data is received as a normal response.
If the buffer is in the reception disabled state, the data is discarded and an overrun error
occurs.

SOF Interpolation Function
When the function controller function is selected and if data could not be received at intervals of 1
ms (when using full-speed operation) or 125 s (when using high-speed operation) because an
SOF packet was corrupted or missing, this module interpolates the SOF. The SOF interpolation
operation begins when the USBE and SCKE bits in SYSCFG have been set to 1 and an SOF
packet is received. The interpolation function is initialized under the following conditions.
Power-on reset
USB bus reset
Suspended state detected
Also, the SOF interpolation operates under the following specifications.
125 s/1 ms conforms to the results of the reset handshake protocol.
The interpolation function is not activated until an SOF packet is received.
After the first SOF packet is received, either 125 s or 1 ms is counted with an internal clock
of 48 MHz, and interpolation is carried out.
After the second and subsequent SOF packets are received, interpolation is carried out at the
previous reception interval.
Interpolation is not carried out in the suspended state or while a USB bus reset is being
received. (With suspended transitions in high-speed operation, interpolation continues for 3 ms
after the last packet is received.)
This module supports the following functions based on the SOF detection. These functions also
operate normally with SOF interpolation, if the SOF packet was corrupted.

If an SOF packet is missing when full-speed operation is being used, the FRNM bit in FRMNUM
is not refreshed. If a SOF packet is missing during high-speed operation, the UFRNM bit in
UFRMNUM is refreshed. However, if a SOF packet for which the UFRNM = 000 is missing, the
FRNM bit is not refreshed. In this case, the FRNM bit is not refreshed even if successive SOF
packets other than UFRNM = 000 are received normally.

transfers, the condition is generated only in transfer frames that are based on the
interval counter. "Invalid" indicates that the condition is generated regardless of the
interval counter.
2. This indicates that a transaction is generated regardless of whether or not there is a
receive area. If there was no receive area, however, the received data is destroyed.
3. This indicates that a transaction is generated regardless of whether or not there is any

Section 26 USB 2.0 Host/Function Module
Transfer Schedule
This section describes the transfer scheduling within a frame of this module. After the module
sends an SOF, the transfer is carried out in the sequence described below.
1. Execution of periodic transfers
A pipe is searched in the order of Pipe 1 Pipe 2 Pipe 6 Pipe 7 Pipe 8 Pipe 9, and
then, if the pipe is one for which an isochronous or interrupt transfer transaction can be
generated, the transaction is generated.
2. Setup transactions for control transfers
The DCP is checked, and if a setup transaction is possible, it is sent.
3. Execution of bulk and control transfer data stages and status stages
A pipe is searched in the order of DCP Pipe 1 Pipe 2 Pipe 3 Pipe 4 Pipe 5, and
then, if the pipe is one for which a bulk or control transfer data stage or a control transfer status
stage transaction can be generated, the transaction is generated.
If a transfer is generated, processing moves to the next pipe transaction regardless of whether
the response from the peripheral device is ACK or NAK. Also, if there is time for the transfer
to be done within the frame, step 3 is repeated.
(3)
USB Communication Enabled
Setting the UACT bit of the DVSTCTR register to 1 initiates sending of an SOF or SOF, and
makes it possible to generate a transaction.
Setting the UACT bit to 0 stops the sending of the SOF or SOF and initiates a suspend state. If
the setting of the UACT bit is changed from 1 to 0, processing stops after the next SOF or SOF is
sent.

This module consists of seven functional blocks listed in table 27.3. Figure 27.1 shows the entire
block diagram of this module.
Table 27.3 Functional Blocks
Block Name
Overview of Functions
Input timing control
block
Selects the timing of the sync signal input with respect to the clock rising
or falling edge and selects the sync signal polarity. It also selects the
timing of the BT.601 and BT.656 video input signals with respect to the
clock rising or falling edge.
Video receiving block
(1) Captures the input video and applies the scaling, contrast, and
brightness processing.
(2) Converts the YC format into the RGB565 format and stores the data
through the IV1-BUS.
(3) Applies field skipping processing, and stores the resultant data in the
RGB565 format through the IV1-BUS.
Video supplying block Reads video data through the IV2-BUS.
Graphics block 1
Reads a graphics image (layer 1) from the memory through the IV3-BUS,
overlays it on the video sent from the video supplying block, and outputs
the result to graphics block 2.
Graphics block 2
Reads a graphics image (layer 2) from the memory through the IV4-BUS,
overlays it on the output from graphics block 1, and outputs the result to
the panel control block.
Panel control block
Generates the sync signals for output to the panel.
Output timing control
block
Controls the timing of the sync signal output with respect to the clock
rising or falling edge and controls the sync signal polarity. It also controls
the timing of the RGB666 video output signals with respect to the clock
rising or falling edge.

Video Recording Function
This module stores the captured video in the RGB565 format at a 1/2-field rate (NTSC: 30 fps;
PAL: 25 fps) (video recording function) after contrast and brightness adjustment. For the
capturing function, refer to section 27.6.1 (1), Capturing.
The destination address of recording is calculated according to the register settings of the base
address, line offset, field offset, and number of fields to be stored. After data has been written for
the specified number of fields, the memory is overwritten by new video from the first address. The
current field number being written can be monitored through the status register. After one field of
video data is written, an interrupt is sent to the CPU to indicate the completion of writing.

(a) (The number of operations of writing to the buffer in the video display controller 3)
(the number of operations of reading from the buffer) amount of data for two lines
(b) (The number of operations of writing to the buffer in the video display controller 3)
(the number of operations of reading from the buffer)
Case (a) arises when there is a shortage of IV1-BUS bandwidth.
On the other hand, case (b) arises when less than the normal amount of data is written
for one line, due to a malfunction of external input.
3. Only 0 can be written.

When AEN = 1 and WE = 1, the value is loaded in the internal circuits in synchronization with
Vsync.
If AMOD[1:0] = [0 0], the value specified in DEFA is applied to the control area.
If AMOD[1:0] = [0 1], the ACOEF value is added to the DEFA value according to the frame rate
(ARATE) and the result is applied to the control area as the value. When the value becomes
255 or larger, processing stops (fade-in).
If AMOD[1:0] = [1 0], the ACOEF value is subtracted from the DEFA value according to the
frame rate (ARATE) and the result is applied to the control area as the value. When the
value becomes 0 or smaller, processing stops (fade-out).

Note: When the bus format is RGB444, only the CROMAKR[3:0], CROMAKG[3:0], and
CROMAKB[3:0] bits are valid.
When WE =1 in GROPEDPA, the register setting is loaded in the internal circuits in
synchronization with Vsync.
While the chroma-key processing is enabled, if the graphics data values (RGB16 format) of a
pixel all match the CROMAKR[4:0], CROMAKG[5:0], and CROMAKB[4:0] settings, the pixel
color is replaced with the color (RGB16 format) specified in the chroma-key color register
(GROPCRKY1) and processing specified through the ALPHA[7:0] bits is applied.
Chroma-keying thus enables characters or a cursor to be displayed on the lower layer.

calculation is done as follows.
Output R = R (current layer) + R (lower layer) (1 – )
Output G = G (current layer) + G (lower layer) (1 – )
Output B = B (current layer) + B (lower layer) (1 – )

Video Display Position and Register Settings
As the display block does not have frame memory, specify through registers the vertical start
position and number of line buffers for the video according to the panel specifications (HSYNC
cycle). For the vertical video position, first calculate the register settings to place the video along
the top end, and then calculate the settings to place the video at the center or along the bottom end.

Note:
*
When (8) is negative, the data rate of the input video is larger than that of the video
output to the panel. In this case, after video data begins to be stored in the line buffer,
start reading from the buffer while only one to several lines of data are stored, so that
the buffer does not overflow.
When (8) is positive, the data rate of the input video is smaller than that of the video
output to the panel. In this case, start reading from the line buffer after the buffer has
stored enough input data, so that the buffer does not underflow (the line buffer does not
become empty).
Note that when the line buffer is large enough (for example, when the buffer can store
one field of data), the above restrictions are loosened.
Step 2: To place the video at the center or along the bottom end, calculate the new settings from
the values obtained in step 1.
Note: Video cannot be displayed in the last line of the panel.

28.2.1
Input Data Register (SRCID)
SRCID is a readable/writable register that is used to input the data before sampling rate
conversion. All the bits are read as 0. The data input to SRCID is stored in the 8-stage input data
FIFO. When the number of data units in the input data FIFO is 8, writing to SRCID has no effect.
(1)
Input Data Register_0 (SRCID_0)
SRCID_0 is a 32-bit register. For stereo data, bits 31 to 16 are for Lch data, and bits 15 to 0 are for
Rch data. For monaural data, data in bits 31 to 16 is valid, and data in bits 15 to 0 is invalid.

Control Register (SRCCTRL)
SRCCTRL is a 16-bit readable/writable register that enables/disables the module operation,
enables/disables the interrupt requests, and specifies flush processing, clear processing of the
internal work memory, and the input and output sampling rates.

When OVEN = 1: Conversion processing is stopped
until the OVF bit is cleared by the CPU accessing to
SRCSTAT when the output data FIFO overwrite
interrupt is generated. At this time, conversion result
writing to the output data FIFO is also stopped.
OVEN = 0: The OVF bit is automatically cleared when
the output data FIFO has space, and conversion

Internal Work Memory Flush
Writing 1 to this bit starts converting the sampling rate
of all the data in the input FIFO, input buffer memory,
and intermediate memory (i.e., flush processing). This
bit is always read as 0. When SRCEN = 0, writing 1 to
this bit does not trigger flush processing.
In addition, when 1 is written to the FL bit while the
number of data units in the input buffer memory is
less than the values shown in tables 28.9 and 28.10,
valid output data cannot be received. Thus the
internal work memory is cleared without triggering the
flush processing.

Interrupts
This module has five interrupt sources: input data FIFO empty (IDEI), output data FIFO full
(ODFI), output data FIFO overwrite (OVF), output data FIFO underflow (UDF), and conversion
end (CEF). Table 28.11 summarizes the interrupts.

When the interrupt condition is satisfied, the CPU executes the interrupt exception handling
routine. The interrupt source flags should be cleared in the routine.
The IDEI and ODFI interrupts can activate the direct memory access controller when the direct
memory access controller is set to allow this. If the direct memory access controller is activated,
the interrupts from this module are not sent to the CPU. When the direct memory access controller
has written data to SRCID resulting in the number of data units in the input data FIFO exceeding
that of the specified triggering number, the IINT bit is cleared to 0. Similarly, when the direct
memory access controller has read data from SRCOD resulting in the number of data units in the
output data FIFO being less than the specified triggering number, the OINT bit is cleared to 0.

Usage Notes
28.5.1
Notes on Accessing Registers
SH7262 Group, SH7264 Group
After the following write access to SRCCTRL, three cycles of the peripheral clock (P) elapse
before the corresponding bit in SRCSTAT is updated.
Before the FLF bit in SRCSTAT is set after 1 is written to the FL bit in SRCCTRL
Before each bit in SRCSTAT is initialized after 1 is written to the CL bit in SRCCTRL
Before each bit in SRCSTAT is initialized after 1 is written to the SRCEN bit in SRCCTRL
while the SRCEN bit is 0
On the other hand, as the CPU executes any subsequent instruction without waiting for the
completion of the register writing, an instruction that immediately follows that used to write to
SRCCTRL cannot accurately detect the updated state of SRCSTAT. To check the updated
SRCSTAT state, dummy-read SRCCTRL or SRCSTAT after the instruction used to write to
SRCCTRL.
28.5.2
Notes on Flush Processing
When 1 is written to the FL bit in SRCCTRL, this module continues conversion processing by
adding 0-data to the input data end point. Flush processing, therefore, should be performed when
the audio data end point is input and there is no subsequent data.
To perform conversion again after flush processing, clear the internal work memory in either of
the following ways.
Write 1 to the CL bit in SRCCTRL.
Write 0 and then 1 to the SRCEN bit in SRCCTRL.

Section 31 On-Chip RAM
Section 31 On-Chip RAM
This LSI has an on-chip high-speed RAM, which achieves fast access, an on-chip large-capacity
RAM for display area and work area (32 Kbytes for 1-Mbyte version and 320 Kbytes for 640Kbyte version of this RAM are shared with the on-chip data retention RAM), and an on-chip data
retention RAM, which can retain data in deep standby mode. These memory units can be used to
store instructions or data.
The operation and write access to the on-chip high-speed RAM and large-capacity RAM
(including on-chip data retention RAM) can be enabled or disabled through the RAM enable bits
and RAM write enable bits.
The on-chip data retention RAM is assigned to page 5 for 1-Mbyte and page 0 to 2 for 640-Kbyte
versions of the on-chip large-capacity RAM. Retention or non-retention of data by the on-chip
data retention RAM in deep standby mode is selectable on a per-page basis.
31.1

Section 31 On-Chip RAM
Ports
Each page of the on-chip high-speed RAM has two independent read and write ports and is
connected to the internal DMA bus (ID bus), CPU instruction fetch bus (F bus), and CPU
memory access bus (M bus). (Note that the F bus is connected only to the read ports.)
The F bus and M bus are used for access by the CPU, and the ID bus is used for access by the
direct memory access controller.
Each page of the on-chip large-capacity RAM has one read and write port and is connected to
the internal CPU bus (IC bus), internal DMA bus (ID bus) and internal graphic buses 1 to 4
(IV1 to IV4). For 1-Mbyte version, pages 0 and 1 of the on-chip RAM for data retention are
included in page 5 of the on-chip large-capacity RAM. Accordingly, pages 0 and 1 of the onchip RAM for data retention are shared with the read and write port of page 5 of the on-chip
large-capacity RAM. On the other hand, since the on-chip RAM for data retention is included
in page 0 to 2 for 640-Kbyte version, it is shared with the read and write port of the same
pages.
Priority
When the same page of the on-chip high-speed RAM is accessed from different buses
simultaneously, the access is processed according to the priority. The priority is ID bus M
bus F bus.
When the same page of the on-chip large-capacity RAM is accessed from different buses
simultaneously, the access is processed according to the priority. The priority is IV1 bus IV2
bus IV3 bus IV4 bus IC bus (when the IC bus does not have the bus mastership in the
preceding bus cycle) ID bus IC bus (when the IC bus has the bus mastership in the
preceding bus cycle)
Number of access cycles
On-chip high-speed RAM: the number of cycles for access to read or write from buses F and I
is one cycle of I. Number of cycles for access from the ID bus
depend on the ratio of the CPU clock (I) to the bus clock (B).
Table 31.6 indicates number of cycles for access from the ID bus.

Usage Notes
31.2.1
Page Conflict
Section 31 On-Chip RAM
When the same page of the on-chip high-speed RAM or the on-chip large-capacity RAM is
accessed from different buses simultaneously, a conflict on the page occurs. Although each access
is completed correctly, this kind of conflict degrades the memory access speed. Therefore, it is
advisable to provide software measures to prevent such conflicts as far as possible. For example,
no conflict will arise if different pages are accessed by each bus.
31.2.2
RAME and RAMWE Bits
Before disabling memory operation or write access to the on-chip high-speed RAM through the
RAME or RAMWE bit, be sure to read from any address and then write to the same address in
each page; otherwise, the last written data in each page may not be actually written to the RAM.

Data Retention
Data in the on-chip high-speed RAM and the large-capacity RAM (including on-chip data
retention RAM) are retained in the states other than power-on reset and deep standby mode. In
power-on reset and deep standby mode, these RAMs operate as described below.
(1)
Power-on Reset
(a)
On-Chip High-Speed RAM
Data are retained on a power-on reset by disabling the setting of either the RAME or RAMWE bit.
Data are not retained when the setting of the RAME and RAMWE bits are both enabled.
(b)
On-Chip Large-Capacity RAM (Excluding On-Chip Data Retention RAM)
Data are retained on a power-on reset by disabling the setting of either the VRAME or VRAMWE
bit.
Data are not retained when the setting of the VRAME and VRAMWE bits are both enabled.
(c)
On-Chip Data Retention RAM
Data are retained on a power-on reset by disabling the setting of any of the VRAME, VRAMWE,
or RRAMWE, excluding the case that deep standby mode is canceled by power-on reset.
Data are not retained when the setting of the VRAME, VRAMWE and RRAMWE bits are all
enabled.
(2)
Deep Standby Mode
(a)
On-Chip High-Speed RAM and On-Chip Large-Capacity RAM (Excluding On-Chip
Data Retention RAM)
Data are not retained.
(b)
On-Chip Data Retention RAM
Data are retained in deep standby mode by enabling the setting of the RRAMKP bit, excluding the
case that deep standby mode is canceled by power-on reset. In the case that deep standby mode is
canceled by interrupt or pins for cancelling, power-on reset exception handling is executed, but the
data are retained.

32.2.1
Section 32 General Purpose I/O Ports
Port A I/O Register 0 (PAIOR0)
PAIOR0 is a 16-bit readable/writable register that is set the pins on port A as inputs or outputs.
The PA3IOR0 to PA0IOR bits correspond to the PA3 PA0 pins, respectively. If a bit in PAIOR0
is set to 1, the corresponding pin on port A functions as output. If it is cleared to 0, the
corresponding pin function as input. The direction (input or output) should only be modified by
writing once for each pin.
Bits 15 to 4 in PAIOR0 are reserved. These bits are always read as 0. The write value should
always be 0.

Port A Data Registers 1, 0 (PADR1, PADR0)
PBDR1 and PBDR0 are 16-bit readable/writable registers that store port A data. The PA3DR to
PA0DR bits correspond to the PA3 to PA0 pins, respectively.
When a pin function is general output, if a value is written to PADR1 or PADR0, that value is
output from the pin, and if PADR1 or PADR0 is read, the register value is returned regardless of
the pin state.
When a pin function is general input, if PADR1 or PADR0 is read, the pin state, not the register
value, is returned directly. If a value is written to PADR1 or PADR0, although that value is
written into PADR1 or PADR0, it does not affect the pin state. Table 32.13 summarizes PADR1
and PADR0 read/write operation.

Port B I/O Registers 0, 1 (PBIOR0, PBIOR1)
PBIOR0 and PBIOR1 are 16-bit readable/writable registers that are used to set the pins on port B
as inputs or outputs. The PB22IOR to PB1IOR bits correspond to the PB22 to PB1 pins,
respectively. PBIOR1 and PBIOR0 are enabled when the port B pins are functioning as generalpurpose I/O (PB22 to PB1) or TIOC I/O of multi-function timer pulse unit 2. In other states, they
are disabled. If a bit in PBIOR1 or PBIOR0 is set to 1, the corresponding pin on port B functions
as output pin. If it is cleared to 0, the corresponding pin functions as an input pin.
Bits 15 to 7 in PBIOR1 and bit 0 in PBIOR0 are reserved. These bits are always read as 0. The
write value should always be 0.

32.2.6
Port B Data Registers 0, 1 (PBDR0, PBDR1)
PBDR0 and PBDR1 are 16-bit readable/writable registers that store port B data. The PB22DR to
PB1DR bits correspond to the PB22 to PB1 pins, respectively.
When a pin function is general output, if a value is written to PBDR1 or PBDR0, the value is
output directly from the pin, and if PBDR is read, the register value is returned directly regardless
of the pin state.
When a pin function is general input, if PBDR1 or PBDR0 is read, the pin state, not the register
value, is returned directly. If a value is written to PBDR1 or PBDR0, although that value is written
into PBDR1 or PBDR0, it does not affect the pin state. Table 32.14 summarizes PBDR1/PBDR0
read/write operation.

Port C I/O Register 0 (PCIOR0)
PCIOR0 is a 16-bit readable/writable register that is used to set the pins on port C as inputs or
outputs. The PC10IOR to PC0IOR bits correspond to the PC10 to PC0 pins, respectively.
PCIOR0 is enabled when the port C pins are functioning as general-purpose I/O (PC10 to PC0) or
TIOC I/O of multi-function timer pulse unit 2. In other states, PCIOR0 is disabled. If a bit in
PCIOR0 is set to 1, the corresponding pin on port C functions as an output pin. If it is cleared to 0,
the corresponding pin functions as an input pin.
Bits 15 to 11 in PCIOR0, and bits 10 and 9 in PCIOR0 in the SH7262 Group are reserved. These
bits are always read as 0. The write value should always be 0.

32.2.10 Port C Data Register 0 (PCDR0)
PCDR0 is a 16-bit readable/writable register that stores port C data. The PC10DR to PC0DR bits
correspond to the PC10 to PC0 pins, respectively.
When a pin function is general output, if a value is written to PCDR0, that value is output directly
from the pin, and if PCDR0 is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PCDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PCDR0, although that value is written into PCDR0, it
does not affect the pin state. Table 32.15 summarizes PCDR0 read/write operation.

32.2.13 Port D I/O Register 0 (PDIOR0)
PDIOR0 is a 16-bit readable/writable register that is used to set the pins on port D as inputs or
outputs. The PD15IOR to PD0IOR bits correspond to the PD15 to PD0 pins, respectively. The
setting of PDIOR0 is valid for the pins for which general I/O function is selected and has no effect
on the pins for which other function is selected. If a bit in PDIOR0 is set to 1, the corresponding
pin on port D functions as an output. If it is cleared to 0, the corresponding pin functions as an
input.

PDDR0 is a 16-bit readable/writable register that stores port D data. The PD15DR to PD0DR bits
correspond to the PD15 to PD0 pins, respectively.
When a pin function is general output, if a value is written to PDDR0, that value is output directly
from the pin, and if PDDR0 is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PDDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PDDR0, although that value is written into PDDR0, it
does not affect the pin state. Table 32.16 summarizes PDDR0 read/write operation.

PEIOR0 is a 16-bit readable/writable register that is used to set the pins on port F as inputs or
outputs. The PE5IOR to PE0IOR bits correspond to the PE5 to PE0 pins respectively. PEIOR0 is
enabled when the port E pins are functioning as general-purpose inputs/outputs (PE5 to PE0). In
other states, it is disabled. If a bit in PEIOR0 is set to 1, the corresponding pin on port E functions
as an output pin. If it is cleared to 0, the corresponding pin functions as an input pin.
Bits 15 to 6 in PEIOR0 are reserved. This bit is always read as 0. The write value should always
be 0.

32.2.18 Port E Data Register 0 (PEDR0)
PEDR0 is a 16-bit readable/writable register that stores port E data. The PE5DR to PE0DR bits
correspond to the PE5 to PE0 pins, respectively.
6 pins on Port E are open-drain outputs. When a pin function is general output, if 0 is written to
PEDR0, 0 is output from the pin and if 1 is written to, the pin will be in the high-impedance state.
If PEDR0 is read, the register value is returned directly regardless of the pin state.
When a pin function is general input, if PEDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PEDR0, although that value is written into PEDR0, it
does not affect the pin state. Table 32.17 summarizes PEDR0 read/write operation.

32.2.21 Port F I/O Register 0 (PFIOR0)
PFIOR0 is a 16-bit readable/writable register that is used to set the pins on port F as inputs or
outputs. The PF12IOR to PF0IOR bits correspond to the PF12 to PF0 pins, respectively. PFIOR0
is enabled when the port F pins are functioning as general-purpose I/O (PF12 to PF0) or TIOC I/O
of multi-function timer pulse unit 2. In other states, they are disabled. If a bit in PFIOR0 is set to
1, the corresponding pin on port F functions as an output. If it is cleared to 0, the corresponding
pin functions as an input.
Bits 15 to 13 in PFIOR0 are reserved. This bit is always read as 0. The write value should always
be 0.

32.2.22 Port F Data Register 0 (PFDR0)
PFDR0 is a 16-bit readable/writable register that stores port F data. The PF12DR to PF0DR bits
correspond to the PF12 to PF pins respectively.
When a pin function is general output, if a value is written to PFDR0, that value is output directly
from the pin, and if PEDR0 is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PFDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PFDR0, although that value is written into PFDR0, it does
not affect the pin state. Table 32.18 summarizes PFDR0 read/write operation.

32.2.25 Port G I/O Registers 0, 1 (PGIOR0, PGIOR1)
PGIOR1 and PGIOR0 are 16-bit readable/writable registers that are used to set the pins on port G
as inputs or outputs. The PG24IOR to PG0IOR bits correspond to the PG24 to PG0, respectively.
PGIOR1 and PGIOR0 are enabled when the port G pins are functioning as general-purpose I/O
(PG24 to PG0) or TIOC I/O of multi-function timer pulse unit 2. In other states, they are disabled.
If bits in PGIOR1 and PGIOR0 are set to 1, corresponding pins on port G functions as outputs. If
they are cleared to 0, the corresponding pins function as inputs.
Bits15 to 9 in PGIOR1, and bits 8 to 5 in PGIOR1 in the SH7262 Group are reserved. These bits
are always read as 0. The write values should always be 0.

32.2.26 Port G Data Register 0, 1 (PGDR0, PGDR1)
PGDR1 and PGDR0 are 16-bit readable/writable registers that store port G data. The PG24DR to
PG0DR bits correspond to the PG24 to PGDR0 pins, respectively.
When a pin function is general output, if a value is written to PGDR1 or PGDR0, that value is
output from the pin, and if PGDR1 or PGDR0 is read, the register value is returned directly
regardless of the pin state.
When a pin function is general input, if PGDR1 or PGDR0 is read, the pin state, not the register
value, is returned directly. If a value is written to PGDR1 or PGDR0, although that value is
written into PGDR1 or PGDR0, it does not affect the pin state. Table 32.19 summarizes
PGDR1/PGDR0 read/write operation.

32.2.31 Port J I/O register 0 (PJIOR0)
PJIOR0 is a 16-bit readable/writable register that is used to set the pins on port J as inputs or
outputs. The PJ11IIOR to PJ0IOR bits correspond to the PJ11 to PJ0 pins respectively. The setting
of PJIOR0 is valid for the pins for which general I/O (PJ11 to PJ0) function or TIOC I/O function
of multi-function timer pulse unit 2 is selected and has no effect on the pins for which other
function is selected. If a bit in PJIOR0 is set to 1, the corresponding pin on port J functions as an
output pin. If it is cleared to 0, the corresponding pin functions as an input pin.
Bits 15 to 12 in PJIOR0, and bits 11 to 4 in PJIOR0 in the SH7262 Group are reserved. These bits
are always read as 0. The write value should always be 0.

32.2.32 Port J Data Register 0 (PJDR0)
PJDR0 is a 16-bit readable/writable register that stores port J data. The PJ11DR to PJ0DR bits
correspond to the PJ11 to PJ0 pins, respectively.
When a pin function is general output, if a value is written to PJDR0, that value is output from the
pin, and if PJDR0 is read, the register value is returned directly regardless of the pin state.
When a pin function is general input, if PJDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PJDR0, although that value is written into PJDR0, it does
not affect the pin state. Table 32.20 summarizes PJDR0 read/write operation.

Usage Notes
32.3.1
Notes on Output Function from PE0 to PE5
About each pair of ports, that is PE0 and PE1, PE2 and PE3, PE4 and PE5, when one port is set to
other than general purpose I/O function (PE0 to PE5) and I2C Bus Interface 3 function (SCL0 to
SCL2, SDA0 to SDA2), the other port can't be used for open-drain output. In that case, the other
port can be used for general purpose or other input function.

Section 33 Power-Down Modes
Section 33 Power-Down Modes
This LSI supports sleep mode, software standby mode, deep standby mode, and module standby
mode. In power-down modes, functions of CPU, clocks, on-chip memory, or part of on-chip
peripheral modules are halted or the power-supply is turned off, through which low power
consumption is achieved. These modes are canceled by a reset or interrupt.
33.1
Features
33.1.1
Power-Down Modes
This LSI has the following power-down modes and function:
1.
2.
3.
4.
Sleep mode
Software standby mode
Deep standby mode
Module standby function
Table 33.1 shows the transition conditions for entering the modes from the program execution
state, as well as the CPU and peripheral module states in each mode and the procedures for
canceling each mode.

Notes: 1. The pin state is retained or set to high impedance. For details, see appendix A, Pin
States.
2. The realtime clock operates when the START bit in the RCR2 register is set to 1. For
details, see section 14, Realtime Clock. When deep standby mode is canceled by a
power-on reset, the running state cannot be retained. Make the initial setting for the
realtime clock again.
3. Setting the bits RRAMKP3 to RRAMKP0 in the RRAMKP register to 1 enables to retain
the data in the corresponding area on the on-chip data-retention RAM during the
transition to deep standby. When the deep standby is canceled by a power-on reset,
the retained contents are initialized. RRAMKP3 and RRAMKP2 can be used only for
640-Kbyte version.
4. Deep standby mode can be canceled by an interrupt (NMI or realtime clock alarm
interrupt), a power-on reset, or change on the pins for canceling (PC8 to PC5,PG10 to
PG11, PJ3, and PJ1). Even when deep standby mode is canceled by a source other
than a reset, power-on reset exception handling is executed instead of interrupt
exception handling. PG10 to PG11 operates as pins for canceling only in 640-Kbyte
version.
5. When software standby mode is canceled by a power-on reset, the retained contents
are initialized.
6. By setting the RAME bit in SYSCR1 or RAMWE bit in SYSCR2 to disable accesses,
contents in the high-speed on-chip RAM can be retained even when software standby
mode is canceled by a power-on reset.
7. By setting the VRAME bit in SYSCR3 or VRAMWE bit in SYSCR4 to disable accesses,
contents in the large-capacity on-chip RAM (including on-chip data-retention RAM) can
be retained even when software standby mode is canceled by a power-on reset.

33.2.10 System Control Register 1 (SYSCR1)
SYSCR1 is an 8-bit readable/writable register that enables or disables access (read and write) to a
specified page in the high-speed on-chip RAM.
When an RAMEn (n = 0 to 3) bit is set to 1, access to page n is enabled. When an RAMEn bit is
cleared to 0, page n cannot be accessed. In this case, an undefined value is returned when reading
data or fetching an instruction from page n, and writing to page n is ignored. The initial value of
an RAMEn bit is 1.
Note that when clearing the RAMEn bit to 0, be sure to execute an instruction to read from or
write to the same arbitrary address in each page before setting the RAMEn bit. If such an
instruction is not executed, the data last written to page n may not be written to the high-speed onchip RAM.
SYSCR1 should be set with a program located in an area other than the high-speed on-chip RAM. Furthermore, an
instruction to read SYSCR1 should be located immediately after the instruction to write to SYSCR1. If not, normal access
is not guaranteed.
Note: When writing to this register, see section 33.4, Usage Notes.

When the RRAMKP3 to RRAMKP0 bits are set to 1, the contents of the corresponding area of the
on-chip data-retention RAM are retained in deep standby mode. When these bits are cleared to 0,
the contents of the corresponding area of the on-chip data-retention RAM are not retained in deep
standby mode.
Note: When writing to this register, see section 33.4, Usage Notes.

33.2.19 Deep Standby Cancel Source Flag Register (DSFR)
DSFR is a 16-bit readable/writable register composed of two types of bits. One is the flag that
confirms which source canceled deep standby mode. The other is the bit that releases the state of
pins after canceling deep standby mode. When deep standby mode is canceled by an interrupt
(NMI, realtime clock alarm interrupt, or change on the pins for canceling) and changes on the pins
for canceling, this register retains the previous data although power-on reset exception handling is
executed. When deep standby mode is canceled by a power-on reset, this register is initialized to
H'0000.
All flags must be cleared immediately before transition to deep standby mode.

Sleep Mode
(1)
SH7262 Group, SH7264 Group
Transition to Sleep Mode
Executing the SLEEP instruction when the STBY bit in STBCR1 is 0 causes a transition from the
program execution state to sleep mode. Although the CPU halts immediately after executing the
SLEEP instruction, the contents of its internal registers remain unchanged. The on-chip peripheral
modules continue to run in sleep mode. The clock output from the CKIO pin is continued.
(2)
Canceling Sleep Mode
Sleep mode is canceled by an interrupt (NMI, IRQ, and on-chip peripheral module), a DMA
address error, or a reset (manual reset or power-on reset).
Canceling by an interrupt
When an NMI, IRQ, or on-chip peripheral module interrupt occurs, sleep mode is canceled and
interrupt exception handling is executed. When the priority level of the generated interrupt is
equal to or lower than the interrupt mask level that is set in the status register (SR) of the CPU,
or the interrupt by the on-chip peripheral module is disabled on the module side, the interrupt
request is not accepted and sleep mode is not canceled.
Canceling by a DMA address error
When a DMA address error occurs, sleep mode is canceled and DMA address error exception
handling is executed.
Canceling by a reset
Sleep mode is canceled by a power-on reset or a manual reset.

Section 33 Power-Down Modes
Software Standby Mode
Transition to Software Standby Mode
The LSI switches from a program execution state to software standby mode by executing the
SLEEP instruction when the STBY bit and DEEP bit in STBCR1 are 1 and 0 respectively. In
software standby mode, not only the CPU but also the clock and on-chip peripheral modules halt.
The clock output from the CKIO pin also stops.
The contents of the CPU and cache registers remain unchanged. Some registers of on-chip
peripheral modules are, however, initialized. As for the states of on-chip peripheral module
registers in software standby mode, see section 36.3, Register States in Each Operating Mode.
The CPU takes one cycle to finish writing to STBCR1, and then executes processing for the next
instruction. However, it takes one or more cycles to actually write. Therefore, execute a SLEEP
instruction after reading STBCR1 to have the values written to STBCR1 by the CPU to be
definitely reflected in the SLEEP instruction.
The procedure for switching to software standby mode is as follows:
1. Clear the TME bit in the timer control register of the watchdog timer (WTCSR) to 0 to stop the
watchdog time.
2. Set the timer counter of the watchdog timer (WTCNT) to 0 and the CKS[2:0] bits in WTCSR
to appropriate values to secure the specified oscillation settling time.
3. After setting the STBY and DEEP bits in STBCR1 to 1 and 0 respectively, read STBCR1.
Then, execute a SLEEP instruction.

Canceling Software Standby Mode
Software standby mode is canceled by interrupts (NMI or IRQ) or a reset (power-on reset). Clock
signal starts to be output from the CKIO pin.
Canceling by an interrupt
When the falling edge or rising edge of the NMI pin (selected by the NMI edge select bit
(NMIE) in interrupt control register 0 (ICR0) of the interrupt controller) or the falling edge or
rising edge of an IRQ pin (IRQ7 to IRQ0) (selected by the IRQn sense select bits (IRQn1S and
IRQn0S) in interrupt control register 1 (ICR1) of the interrupt controller) is detected, clock
oscillation is started. This clock pulse is supplied only to the oscillation settling counter
(watchdog timer) used to count the oscillation settling time.
After the elapse of the time set in the clock select bits (CKS[2:0]) in the watchdog timer
control/status register (WTCSR) of the watchdog timer before the transition to software
standby mode, the watchdog timer overflow occurs. Since this overflow indicates that the
clock has been stabilized, the clock pulse will be supplied to the entire chip after this overflow.
Software standby mode is thus cleared and NMI interrupt exception handling (IRQ interrupt
exception handling in case of IRQ) is started. If the priority level of the generated interrupt is
equal to or lower than the interrupt mask level specified in the status register (SR) of the CPU,
the interrupt request is not accepted and software standby mode is not canceled.
When canceling software standby mode by the NMI interrupt or IRQ interrupt, set the
CKS[2:0] bits so that the watchdog timer overflow period will be equal to or longer than the
oscillation settling time.
The clock output phase of the CKIO pin may be unstable immediately after detecting an
interrupt and until software standby mode is canceled. When software standby mode is
canceled by the falling edge of the NMI pin, the NMI pin should be high when software
standby mode is entered (when the clock pulse stops) and should be low when software
standby mode is canceled (when the clock is initiated after the oscillation settling). When
software standby mode is canceled by the rising edge of the NMI pin, the NMI pin should be
low when software standby mode is entered (when the clock pulse stops) and should be high
when software standby mode is canceled (when the clock is initiated after the oscillation
settling) (This is the same with the IRQ pin.)
Canceling by a reset
When the RES pin is driven low, software standby mode is canceled and the LSI enters the
power-on reset state. After that, if the RES pin is driven high, the power-on reset exception
handling is started.
Keep the RES pin low until the clock oscillation settles. The internal clock will continue to be
output to the CKIO pin.

Section 33 Power-Down Modes
Note on Release from Software Standby Mode
Release from software standby mode is triggered by interrupts (NMI and IRQ) or resets (manual
reset and power-on reset). If, however, a SLEEP instruction and an interrupt other than NMI and
IRQ are generated at the same time, software standby mode may be canceled due to acceptance of
the interrupt.
When initiating a transition to software standby mode, make settings so that interrupts are not
generated before execution of the SLEEP instruction.
(4)
Note on Canceling Software Standby Mode
After software standby mode is canceled, unstable clock pulses are output from the CKIO pin
during oscillation settling time. To prevent malfunction due to the unstable pulses, bits 13 and 12
in FRQCR should be modified.

Software Standby Mode Application Example
This example describes a transition to software standby mode on the falling edge of the NMI
signal, and cancellation on the rising edge of the NMI signal. The timing is shown in figure 33.1.
When the NMI pin is changed from high to low level while the NMI edge select bit (NMIE) in the
interrupt control register 0 (ICR0) is set to 0 (falling edge detection), the NMI interrupt is
accepted. When the NMIE bit is set to 1 (rising edge detection) by the NMI exception service
routine, the STBY and DEEP bits in STBCR1 are set to 1 and 0 respectively, and a SLEEP
instruction is executed, software standby mode is entered. Thereafter, software standby mode is
canceled when the NMI pin is changed from low to high level.

Deep Standby Mode
Transition to Deep Standby Mode
The LSI switches from a program execution state to deep standby mode by executing the SLEEP
instruction when the STBY bit and DEEP bit in STBCR1 are set to 1. In deep standby mode, not
only the CPU, clocks, and on-chip peripheral modules but also power supply is turned off
excluding the on-chip data-retention RAM area specified by the RRAMKP3 to RRAMKP0 bits in
RRAMKP and realtime clock. This can significantly reduce power consumption. Therefore, data
in the registers of the CPU, cache, and on-chip peripheral modules are not retained. Pin state
values immediately before the transition to deep standby mode are retained.
The CPU takes one cycle to finish writing to DSFR, and then executes processing for the next
instruction. However, it actually takes one or more cycles to write. Therefore, execute a SLEEP
instruction after reading DSFR to reflect the values written to DSFR by the CPU in the SLEEP
instruction without fail.
The procedure for switching to deep standby mode is as follows. Figure 33.2 also shows its
flowchart.
1. Set the RRAMKP3 to RRAMKP0 bits in RRAMKP for the corresponding on-chip dataretention RAM area that must be retained. Transfer the programs to be retained to the specified
areas of the on-chip data-retention RAM.
2. Set the RAMBOOT and EBUSKEEPE bits in DSCTR to specify the activation method for
returning from deep standby mode and to select whether the external memory control pin
status is retained or not.
3. When canceling deep standby mode by an interrupt, set the corresponding bit in DSSSR to
select the pin or source to cancel deep standby mode. In this case, specify the input signal
detection mode for the selected pin with the corresponding bit in DSESR.
4. Execute read and write of an arbitrary but the same address for each page in the on-chip dataretention RAM area. When this is not executed, data last written may not be written to the onchip data-retention RAM. If there is a write to the on-chip data-retention RAM after this time,
execute this processing after the last write to the on-chip data-retention RAM.
5. Set the STBY and DEEP bits in STBCR1 to 1.
6. Read out the DSFR register after clearing the flag in the DSFR register. Then execute the
SLEEP instruction.

Section 33 Power-Down Modes
Canceling Deep Standby Mode
Deep standby mode is canceled by interrupts (NMI or realtime clock alarm interrupt), change on
the pins for canceling, or a reset (power-on reset). The realtime clock alarm interrupt can always
cancel deep standby mode regardless of the interrupt priority level or the status register (SR)
setting in the CPU. When canceling the mode by a source other than a reset, a power-on reset
exception handling is executed instead of an interrupt exception handling.
Figure 33.3 shows the flowchart of canceling deep standby mode.

Canceling by a source other than a reset
When the falling or rising edge of the NMI pin (selected by a corresponding bit in DSESR) or
falling or rising edge of the pins for canceling (selected by a corresponding bit in DSESR) is
detected or the realtime clock alarm interrupt (see section 14.4.4, Alarm Function) is
generated, clock oscillation is started after the wait time for the oscillation settling time. After
the oscillation settling time has elapsed, deep standby mode is cancelled and the power-on
reset exception handling is executed.
The clock output phase of the CKIO pin may be unstable immediately after detecting an
interrupt and until deep standby mode is canceled. When deep standby mode is canceled by the
falling edge of the NMI pin, the NMI pin should be high when deep standby mode is entered
(when the clock pulse stops) and should be low when deep standby mode is canceled (when
the clock is initiated after the oscillation settling). When deep standby mode is canceled by the
rising edge of the NMI pin, the NMI pin should be low when deep standby mode is entered
(when the clock pulse stops) and should be high when deep standby mode is canceled (when
the clock is initiated after the oscillation settling). (This is the same with the pins for
canceling.)
Also, the NMI and all the pins which are selected by DSSSR to cancel deep standby mode
should be the following pin levels when the CPU enters deep standby, regardless whether they
will really cancel deep standby mode or not.
The pins that are set as rising edge should be low when the CPU enters deep standby mode.
The pins that are set as falling edge should be high when the CPU enters deep standby
mode.
Canceling with a reset
Driving the RES pin low cancels deep standby mode and causes a transition to the power-on
reset state. After this, driving the RES pin high initiates power-on reset exception handling.
Output of the internal clock from the CKIO pin also starts by driving the RES pin low.
Keep the RES pin low until the clock oscillation has settled.

Operation after Canceling Deep Standby Mode
After canceling deep standby mode, the LSI can be activated through the external memory or from
the on-chip data-retention RAM, which can be selected by setting the RAMBOOT bit in DSCTR.
By setting the EBUSKEEPE bit, the states of the external memory control pins can be retained
even after cancellation of deep standby mode. Table 33.3 shows the pin states after cancellation of
deep standby mode according to the setting of each bit. Table 33.4 lists the external memory
control pins.

When deep standby mode is canceled by interrupts (NMI or realtime clock alarm) or changes on
the pins for canceling, the deep standby cancel source flag register (DSFR) can be used to confirm
which source has canceled the mode.
Pins retain the state immediately before the transition to deep standby mode. However, in system
activation through the external memory, the retention of the states of the external memory control
pins is cancelled so that programs can be fetched after cancellation of deep standby mode. Other
pins, after cancellation of deep standby mode, continue to retain the pin states until writing 0 to the
IOKEEP bit in DSFR after reading 1 from the same bit. In system activation from the on-chip
data-retention RAM, after cancellation of deep standby mode, both the external memory control
pins and other pins continues to retain the pin states until writing 0 to the IOKEEP bit in DSFR
after reading 1 from the same bit. Reconfiguration of peripheral functions is required to return to
the previous state of deep standby mode. Peripheral functions include all functions such as the
clock pulse generator, interrupt controller, general I/O ports, and peripheral modules. After the
reconfiguration, the retention of the pin state can be canceled and the LSI returns to the state prior
to the transition to deep standby mode by reading 1 from the IOKEEP bit in DSFR and then
writing 0 to it.

Notes on Transition to Deep Standby Mode
If multiple canceling sources have been specified and multiple canceling sources are input,
multiple cancel source flags will be set.

Module Standby Function
Transition to Module Standby Function
Setting the standby control register MSTP bits to 1 halts the supply of clocks to the corresponding
on-chip peripheral modules. This function can be used to reduce the power consumption in the
program execution state and sleep mode. Disable a module before placing it in the module standby
mode. In addition, do not access the module's registers while it is in the module standby state.
For details on the states of registers, see section 36.3, Register States in Each Operating Mode.
(2)
Canceling Module Standby Function
The module standby function can be canceled by clearing each MSTP bit to 0, or by a power-on
reset (only possible for the realtime clock, user debugging interface, and direct memory access
controller). When taking a module out of the module standby state by clearing the corresponding
MSTP bit to 0, read the MSTP bit to confirm that it has been cleared to 0.
33.3.6
Adjustment of XTAL Crystal Oscillator Gain
The gain of the crystal oscillator can be adjusted using the GAIN bit in XTALCTR. To modify the
gain, PLL settling time is needed. The settling time is counted using the on-chip watchdog timer.
1. The large gain is selected in the initial state.
2. Set the watchdog timer so that the specified settling time should be obtained and stop the
watchdog timer. Specifically, the following settings are necessary:
TME in WTCSR = 0: Stop the watchdog timer.
CKS[2:0] in WTCSR: Division ratio for watchdog timer count clock
WTCNT: Initial counter value
(The watchdog timer starts counting on the set clock.)
3. Set the GAIN bit to the desired value.
4. The LSI is internally stopped and the watchdog timer starts counting. The clock is supplied
only to the watchdog timer and other internal clocks are stopped. In this state, the CKIO pin
continues to output an unstable clock. To avoid malfunction due to the unstable clock, modify
the CKOEN2 bit in FRQCR appropriately. Since this state is equivalent to the software
standby mode state, some registers of on-chip peripheral modules are initialized. For details,
see section 36.3, Register States in Each Operating Mode.
5. When an overflow occurs on the watchdog timer, the specified clock supply is started and the
LSI starts operation. The watchdog timer stops after an overflow.

Usage Notes on Setting Registers
SH7262 Group, SH7264 Group
When writing to the registers related to power-down modes, note the following.
When writing to the register related to power-down modes, the CPU, after executing a write
instruction, executes the next instruction without waiting for the write operation to complete.
Therefore, to reflect the change specified by writing to the register while the next instruction is
executed, insert a dummy read of the same register between the register write instruction and the
next instruction.

Usage Notes when the Realtime Clock is not Used
When the realtime clock is not used, set the MSTP30 bit in STBCR3 to 1 after setting the bits in
registers of the realtime clock shown below.
Set the RTCEN bit in the control register 2 (RCR2) to 0.
Set the RCKSEL[1:0] bits in the control register 5 (RCR5) to 00.

is cancelled by a power-on reset.
34.4.3
TDO Output Timing
When the emulation command is enabled, a transition on the TDO pin is output on the falling edge
of TCK with the initial value. However, setting a TDO transition timing switching command in
SDIR via the pin and passing the Update-IR state synchronizes the TDO transition with the rising
edge of TCK.
To synchronize the transition of TDO with the falling edge of TCK after setting the TDO
transition timing switching command, the TRST pin must be asserted simultaneously with the
power-on reset. In the case of power-on reset by the RES pin, the sync reset is still in operation for
a certain period in the LSI even after the RES pin is negated. Thus, if the TRST pin is asserted
immediately after the negation of the RES pin, the TDO transition timing switching command is
cleared, resulting in TDO transitions synchronized with the falling edges of TCK. To prevent this,
make sure to allow a period of 20 tcyc or longer between the signal transitions of the RES and
TRST pins.

User Debugging Interface Interrupt
The user debugging interface interrupt function generates an interrupt by setting a command from

exception/interrupt operation, resulting in fetching the exception service routine start address from
the exception handling vector table, jumping to that address, and starting program execution from
that address. This interrupt request has a fixed priority level of 15.
User debugging interface interrupts are accepted in sleep mode, but not in software standby mode.

Usage Notes
1. Once a command of this module has been set, it will not be modified until another command is
not set again. If the same command is to be set continuously, the command must be set after a
command (BYPASS mode, etc.) that does not affect chip operations is once set.
2. In software standby mode and in this module's standby state, none of the functions of this
module can be used. To retain the TAP status before and after standby mode, keep TCK high
before entering standby mode.
3. Regardless of whether this module is used, make sure to keep the TRST pin low to initialize
this module at power-on or in recovery from deep standby by the RES pin assertion.
4. If the TRST pin is asserted immediately after the setting of the TDO transition timing
switching command and the negation of the RES pin, the TDO transition timing switching
command is cleared. To avoid this case, make sure to put 20 tcyc or longer between the signal
transition timing of the RES and TRST pins. For details, see section 34.4.3, TDO Output
Timing.
5. When starting the TAP controller after the negation of the TRST pin, make sure to allow 200

When a PWCYR_n compare match occurs, PWCNT_n is cleared and data is transferred from the
buffer register (PWBFR_n) to the duty register (PWDTR_n).
PWCYR_n should be written to only while PWCNT_n is stopped. A value of H'FC00 must not be
set to PWCYR_n.

PWM Duty Registers_nA, nC, nE, nG (PWDTR_nA, PWDTR_nC, PWDTR_nE,
PWDTR_nG) (n = 1, 2)
There are four PWDTR_n registers (PWDTR_nA, PWDTR_nC, PWDTR_nE, and PWDTR_nG).
The PWDTR_nA is used for outputs PWMnA and PWMnB, PWDTR_nC for outputs PWMnC
and PWMnD, PWDTR_nE for outputs PWMnE and PWMnF, and PWDTR_nG for outputs
PWMnG and PWMnH.
PWDTR_n can not be directly accessed by the CPU. When a PWCYR_n compare match occurs,
data is transferred from the buffer register (PWBFR_n) to the duty register (PWDTR_n).
PWDTR_n is initialized to H'00 when the CST bit is cleared to 0.

Operation
35.5.1
PWM Operation
PWM waveforms are output from pins PWM1A to PWM1H and PWM2A to PWM2H as shown
in figure 35.7.
(1)
Initial Settings
Set the PWM output polarity in PWPR_n; select the clock to be input to PWCNT_n with the
CKS2 to CKS0 bits in PWCRn; set the PWM conversion cycle in PWCYR_n; and set the first
frame of data in PWBFR_nA, PWBFR_nC, PWBFR_nE, and PWBFR_nG.
(2)
Activation
When the CST bit in PWCR_n is set to 1, PWCNT_n starts counting up. On compare match
between PWCNT_n and PWCYR_n, data is transferred from the buffer register to the duty
register and the CMF bit in PWCR_n is set to 1. At the same time, if the IE bit in PWCR_n has
been set to 1, an interrupt can be requested or the direct memory access controller can be
activated.
(3)
Waveform Output
The PWM outputs selected by the OTS bits in PWDTR_nA, PWDTR_nC, PWDTR_nE, and
PWDTR_nG go high when a compare match occurs between PWCNT_n and PWCYR_n. The
PWM outputs not selected by the OTS bit are low. When a compare match occurs between
PWCNT_n and PWDTR_nA, PWDTR_nC, PWDTR_nE, or PWDTR_nG, the corresponding
PWM output goes low. If the corresponding bit in PWPR_n is set to 1, the output is inverted.

Next Frame
When a compare match occurs between PWCNT_n and PWCYR_n, data is transferred from the
buffer register to the duty register. PWCNT_n is reset and starts counting up from H'000. The
CMF bit in PWCR_n is set, and if the IE bit in PWCR_n has been set, an interrupt can be
requested or the direct memory access controller can be activated.
(5)
Stopping
When the CST bit in PWCR_n is cleared to 0, PWCNT_n is reset and stops. All PWM outputs go
low (or high if the corresponding bit in PWPR_n is set to 1).
35.5.2
Buffer Transfer Control
Setting a corresponding bit in the PWM buffer transfer control register disables a buffer transfer
on compare match. This prevents the output from changing when compare match occurs while the
buffer register is being changed. A buffer transfer on compare match is resumed after cleaning the
bit.

Usage Note
35.6.1
Conflict between Buffer Register Write and Compare Match
If a PWBFR_n write is performed in the state immediately after a cycle register compare match,
the buffer register and duty register are both modified. PWM output changed by the cycle register
compare match is not changed by modification of the duty register due to conflict. This may result
in unanticipated duty output.
Buffer register modification must be completed before automatic transfer by the direct memory
access controller, exception handling due to a compare match interrupt, or the occurrence of a
cycle register compare match on detection of the rise of CMF (compare match flag) in PWCR_n.

Section 36 List of Registers
Section 36 List of Registers
This section gives information on the on-chip I/O registers of this LSI in the following structures.
1.
Register Addresses (by functional module, in order of the corresponding section numbers)
Registers are described by functional module, in order of the corresponding section numbers.
Access to reserved addresses which are not described in this register address list is prohibited.
When registers consist of 16 or 32 bits, the addresses of the MSBs are given when big endian
mode is selected.
An asterisk (*) in the column "Access Size" indicates that the unit of access in reading differs
from that in writing for the given register. For details, see the register descriptions in the relevant
section.
2. Register Bits
Bit configurations of the registers are described in the same order as the Register Addresses
(by functional module, in order of the corresponding section numbers).
Reserved bits are indicated by "—" in the bit name.
No entry in the bit-name column indicates that the whole register is allocated as a counter or
for holding data.
3. Register States in Each Operating Mode
Register states are described in the same order as the Register Addresses (by functional
module, in order of the corresponding section numbers).
For the initial state of each bit, refer to the description of the register in the corresponding
section.
The register states described are for the basic operating modes. If there is a specific reset for an
on-chip peripheral module, refer to the section on that on-chip peripheral module.
4. Notes when Writing to the On-Chip Peripheral Modules
To access an on-chip module register, two or more peripheral module clock (P) cycles are
required. When the CPU writes data to the internal peripheral registers, the CPU performs the
succeeding instructions without waiting for the completion of writing to registers. For
example, a case is described here in which the system is transferring to the software standby
mode for power savings. To make this transition, the SLEEP instruction must be performed
after setting the STBY bit in the STBCR1 register to 1. However a dummy read of the
STBCR1 register is required before executing the SLEEP instruction. If a dummy read is
omitted, the CPU executes the SLEEP instruction before the STBY bit is set to 1, thus the
system enters sleep mode not software standby mode. A dummy read of the STBCR1 register
is indispensable to complete writing to the STBY bit. To reflect the change by internal
peripheral registers while performing the succeeding instructions, execute a dummy read of
registers to which write instruction is given and then perform the succeeding instructions.

SH7262 Group, SH7264 Group
Power-On/Power-Off Sequence
The 1.2-V power supply (VCC, PLLVCC, USBAVCC, USBDVCC, and USBUVCC) and 3.3-V power
supply (PVCC, AVCC, USBAPVCC, and USBDPVCC) can be turned on and off in any order.
When turning on the power, be sure to drive both the TRST and RES pins low; otherwise, the
output pins and input/output pins output undefined levels, resulting in system malfunction.
When turning off the power, drive the TRST and RES pins low if the undefined output may cause
a problem.

Notes: 1. The maximum value (fmax) of B (external bus clock) depends on the number of wait
cycles and the system configuration of your board.
2. 1/2 tcyc indicated in minimum and maximum values for the item of delay, setup, and hold
times represents a half cycle from the rising edge with a clock. That is, 1/2 tcyc describes
a reference of the falling edge with a clock.
3. Values when SDRAM is used. Be sure to make necessary settings in ACSWR. (For
details, refer to the descriptions from section 9.4.8, AC Characteristics Switching
Register (ACSWR), to section 9.4.10, Sequence to Write to ACSWR.)
4. Be sure to make necessary settings in ACSWR. (For details, refer to the descriptions

Notes: 1. Indicates the power-on reset by low-level input to the RES pin. The pin states after a
power-on reset by the user debugging interface reset assert command or the watchdog
timer overflow is the same as the initial pin states at normal operation (see section 32,
General Purpose I/O Ports).

2. After the chip has shifted to the power-on reset state from deep standby mode by the
input on any of pins NMI, PC8 to PC5, PJ3, and PJ1, the pins retain the state until the
IOKEEP bit in the deep standby cancel source flag register (DSFR) is cleared (see
section 33, Power-Down Modes).
3. The EBUSKEEPE bit in deep standby control register (DSTCR) (see section 33, PowerDown Modes).
4. This LSI enters the power-on reset state for a certain period after recovery from deep
standby control mode (see section 33, Power-Down Modes).
5. Depends on the setting of the RCKSEL bit in the realtime clock control register 5
(RCR5) (see section 14, Realtime Clock).
6. When pins for the connection with a crystal resonator are not used, the input pins
(EXTAL, RTC_X1, AUDIO_X1, and USB_X1) must be fixed (pull-up/down resistor,
power supply, or ground.) and the output pins (XTAL, RTC_X2, AUDIO_X2, and
USB_X2) must be open.
7. Depends on the setting of the CKOEN bit in the frequency control register (FRQCR) of
the clock pulse generator (see section 5, Clock Pulse Generator).
8. Depends on the setting of the AXTALE bit in the software reset control register
(SWRSTCR) (see section 33, Power-Down Modes).
9. Depends on the setting of the HIZ bit in the standby control register 3 (STBCR3) (see
section 33, Power-Down Modes).
10. Depends on the setting of the HIZMEM bit in the common control register (CMNCR) of
the bus state controller (see section 9, Bus State Controller).
11. Depends on the setting of the HIZCNT bit in the common control register (CMNCR) of
the bus state controller (see section 9, Bus State Controller).
12. Depends on the setting of the corresponding bit in the deep standby cancel source
select register (DSSSR) (see section 33, Power-Down Modes).
13. Depends on the setting of the RTCEN bit in the realtime clock control register 2 (RCR2)
(see section 14, Realtime Clock).
14. Z when the TAP controller of the user debugging interface is neither the Shift-DR nor
Shift-IR state.
15. These are the pin states in product chip mode (ASEMD H). See the Emulation
Manual for the pin states in ASE mode (ASEMD L).
16. When this is an output, the output is fixed to either the High or Low level. There is no
oscillation.

Description amended
The CPU in this LSI is an SH-2A CPU, which provides
upward compatibility for SH-1, SH-2, and SH-2E CPUs at
object code level. It has a RISC-type instruction set,
superscalar architecture, and Harvard architecture, for
superior rates of instruction execution. In addition, an
independent 32-bit internal-bus architecture
enhances data processing power. This CPU brings the
user the ability to set up high-performance systems with
strong functionality at less expense than was achievable
with previous microcontrollers, and is even able to handle
realtime control applications requiring high-speed
characteristics.

Description added
Since the analog power supply pins of the PLL are
sensitive to the noise, the system may malfunction due to
inductive interference at the other power supply pins. To
prevent such malfunction, the analog power supply pins
and the digital power supply pins Vcc and PVcc should not
supply the same resources on the board if at all possible.
Ensure that PLLVcc has the same electric potential as Vcc.

Notes: 1. The number of idle cycles is determined by the setting of the CSnWCR.HW[1:0] bits on
the previous cycle. The number of idle cycles will be the number shown at the left when
HW[1:0] ≠ B'00, will be the number shown at the right when HW[1:0] = B'00. Also, for
CSn spaces for which the CSnWCR.HW[1:0] bits do not exist, the number of idle cycles
shown at the right will be used.
2. The number of idle cycles is determined by the setting of the CSnWCR.TEH[3:0] bits on
the previous cycle. The number of idle cycles will be the number shown at the left when
TEH[3:0] ≠ B'0000, will be the number shown at the right when TEH[3:0] = B'0000.

Description amended
(3) On-Chip Peripheral
Module Access
For example, a case is described here in which the system
is transferring to the software standby mode for power
savings. To make this transition, the SLEEP instruction
must be performed after setting the STBY bit in the
STBCR1 register to 1. However a dummy read of the
STBCR1 register is required before executing the SLEEP
instruction. If a dummy read is omitted, the CPU executes
the SLEEP instruction before the STBY bit is set to 1, thus
the system enters sleep mode not software standby mode.
A dummy read of the STBCR1 register is indispensable to
complete writing to the STBY bit.

Operation
513
TCDR is a 16-bit register used only in complementary
PWM mode. Set half the PWM carrier sync value (a value
of two times TDDR + 3 or greater) as the TCDR register
value. This register is constantly compared with the TCNTS
counter in complementary PWM mode, and when a match
occurs, the TCNTS counter switches direction (decrement
to increment).
Description amended
Channels 0 to 4 can all be designated for synchronous
operation.

Description amended
Table 11.42 Cascaded
Combinations
For simultaneous input capture of TCNT_1 and TCNT_2
during cascaded operation, additional input capture input
pins can be specified by the input capture control register
(TICCR). The edge detection that is the condition for input
capture uses a signal representing the logical OR of the
original input pin and the added input pins. For details, see

PWM output is generated using one TGR as the cycle
register and the others as duty registers. The output
specified in TIOR is performed by means of compare
matches. Upon counter clearing by a cycle register
compare match, the output value of each pin is the initial
value set in TIOR.

A PWM waveform is generated by output of the output
level selected in the timer output control register in the
event of a compare-match between a counter and compare
register. While TCNTS is counting, compare register and
temporary register values are simultaneously compared to
create consecutive PWM pulses from 0 to 100%.

15.4.1 Overview
747
Description amended
For serial communication, this module has an
asynchronous mode in which characters are synchronized
individually, and a clock synchronous mode in which
communication is synchronized with clock pulses. Note that
on the SH7262 channels other than 0 to 2, and on the
SH7264 channels other than 0 to 3, cannot be set to clock
synchronous mode.
This module has a 16-stage FIFO buffer for both
transmission and receptions, reducing the overhead of the
CPU, and enabling continuous high-speed communication.
Furthermore, channel 1 on the SH7262, and channels 1
and 3 on the SH7264, have RTS and CTS signals to be
used as modem control signals.

If 0 is written to the SPE bit in the control register (SPCR)
or this module clears the SPE bit to 0 because of the
detection of a mode fault error, this module disables the
module function, and initializes a part of the module
function. When a power-on reset is generated, this module
initializes all of the module function. An explanation

26.4.4 FIFO Buffer Memory 1509
Description amended
(1) FIFO Buffer Memory
Allocation
When continuous transfer mode has been selected using
the CNTMD bit in PIPE CFG, the BUFSIZE bits should be
set so that the buffer memory size should be an integral
multiple of the maximum packet size. When double buffer
mode has been selected using the DBLB bit in PIPE CFG,
two planes of the memory area specified using the
BUFSIZE bits in PIPEBUF can be assigned to a single
pipe.
(a) Buffer Status
1510
Description amended
Tables 26.18 and 26.19 show the buffer status. The buffer
memory status can be confirmed using the BSTS bit in
DCPCTR and the INBUFM bit in PIPEnCTR. The access
direction for the buffer memory can be specified using
either the DIR bit in PIPE CFG or the ISEL bit in
CFIFOSEL (when DCP is selected).

DCPCFG and PIPE CFG. This selection is valid for PIPE1
to PIPE5 and DCP.

Method of Determining if Reading or Transmitting Data is Enabled
Continuous transfer
(CNTMD = 1)
In the receiving direction (DIR = 0), reading data from the FIFO buffer is
enabled when:
•
The number of the data bytes received in the FIFO buffer assigned to
the selected pipe becomes the same as the number of assigned data
bytes (DCP: fixed at 256 bytes, pipes 1 to 5 (BUFSIZE + 1) × 64).
•
This module receives a short packet other than a zero-length packet.
•
This module receives a zero-length packet when data is already
stored in the FIFO buffer assigned to the selected pipe.
or
•
This module receives the number of packets equal to the transaction
counter value specified for the selected pipe. (PIPE1 to PIPE5 only)
In the transmitting direction (DIR = 1), transmitting data from the FIFO
buffer is enabled when:

In a DMA transfer, the DMA transfer end sampling enable (TENDE) bit
is set to 1, a number of data bytes less than the size of a single FIFO
buffer plane assigned to the selected pipe (or 0 bytes) is written to the
FIFO buffer, and the DMA transfer end signal is received (PIPE1 to
PIPE5 only).

(2) FIFO Port Functions
Also, the bus width to be accessed should be selected
using the MBW bit. The buffer memory access direction
conforms to the DIR bit in PIPE CFG. The ISEL bit
determines this only for the DCP.

26.4.5 Control Transfers
(DCP)
1526
Description deleted
A transaction is executed by setting the PID bits in the
DCPCTR register to BUF. The BRDY interrupt or the
BEMP interrupt can be used to detect the end of data
transfer. Use the BRDY interrupt to detect the end of
control write transfers and the BEMP interrupt to detect the
end of control read transfers.
(2) Control Transfers when
the Function Controller
Function is Selected
(b) Data Stage
With control write transfers during high-speed operation,
the NYET handshake response is carried out based on the
state of the buffer memory.

4. Notes when Writing to the On-Chip Peripheral Modules
To access an on-chip module register, two or more
peripheral module clock (P) cycles are required. When
the CPU writes data to the internal peripheral registers,
the CPU performs the succeeding instructions without
waiting for the completion of writing to registers. For
example, a case is described here in which the system
is transferring to the software standby mode for power
savings. To make this transition, the SLEEP instruction
must be performed after setting the STBY bit in the
STBCR1 register to 1. However a dummy read of the
STBCR1 register is required before executing the
SLEEP instruction. If a dummy read is omitted, the
CPU executes the SLEEP instruction before the STBY
bit is set to 1, thus the system enters sleep mode not
software standby mode. A dummy read of the STBCR1
register is indispensable to complete writing to the
STBY bit.
