It combines, on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F8355 and 56F8155 are well-suited for many applications. The devices include many peripherals that are especially useful for motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control (56F8355 only), engine management, noise suppression, remote utility metering, industrial control for power, lighting, and automation applications. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized control applications. The 56F8355 and 56F8155 support program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. These devices also provide two external dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. 1.2.1 56F8355 Features The 56F8355 controller includes 256KB of Program Flash and 8KB of Data Flash (each programmable through the JTAG port) with 4KB of Program RAM and 16KB of Data RAM. A total of 16KB of Boot Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 7 be independently bulk erased or erased in page sizes. Program Flash page erase size is 1KB. Boot and Data Flash page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased. A key application-specific feature of the 56F8355 is the inclusion of two Pulse Width Modulator (PWM) modules. These modules each incorporate three complementary, individually programmable PWM signal output pairs (each module is also capable of supporting six independent PWM functions, for a total of 12 PWM outputs) to enhance motor control functionality. Complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. The up-counter value is programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance Motors); and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”, write-once protection feature for key parameters is also included. A patented PWM waveform distortion correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. The PWM modules provide a reference output to synchronize the Analog-to-Digital Converters through two channels of Quad Timer C. The 56F8355 incorporates two Quadrature Decoders capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. Speed computation capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the Quadrature Decoder can be programmed with a time-out value to alert when no shaft motion is detected. Each input is filtered to ensure only true transitions are recorded. This controller also provides a full set of standard programmable peripherals that include two Serial Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of these interfaces can be used as General-Purpose Input/Outputs (GPIOs) if that function is not required. A Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal interrupt controller are included on the 56F8355. 1.2.2 56F8155 Features The 56F8155 controller includes 256KB of Program Flash, programmable through the JTAG port, and 16KB of Data RAM.

Together, PE, CodeWarrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development. 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 9 1.4 Architecture Block Diagram Note: Features in italics are NOT available in the 56F8155 device and are shaded in the following figures. The 56F8355/56F8155 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the 56800E system buses communicate with internal memories and the IP Bus Bridge. Table 1-1 lists the internal buses in the 56800E architecture and provides a brief description of their function. Figure 1-2 shows the peripherals and control blocks connected to the IP Bus Bridge. The figures do not show the on-board regulator and power and ground signals. They also do not show the multiplexing between peripherals or the dedicated GPIOs. Please see Part 2, Signal/Connection Descriptions, to see which signals are multiplexed with those of other peripherals. Also shown in Figure 1-2 are connections between the PWM, Timer C and ADC blocks. These connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The Timer C channel indicated can generate periodic start (SYNC) signals to the ADC to start its conversions. In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer C input channel as indicated. The timer can then be used to introduce a controllable delay before generating its output signal. The timer output then triggers the ADC. To fully understand this interaction, please see the 56F8300 Peripheral User Manual for clarification on the operation of all three of these peripherals. 56F8355 Technical Data, Rev. 12 10 Freescale Semiconductor Preliminary Architecture Block Diagram 5 JTAG / EOnCE Boot Flash pdb_m[15:0] pab[20:0] Program Flash Program RAM cdbw[31:0] 56800E CHIP TAP Controller EMI* 11 4 6 Address Data Control TAP Linking Module xab1[23:0] xab2[23:0] Data RAM External JTAG Port Data Flash cdbr_m[31:0] xdb2_m[15:0] IPBus Bridge To Flash Control Logic NOT available on the 56F8155 device. * EMI not functional in this package; since only part of the address/data bus is bonded out, use as GPIO pins IPBus Flash Memory Module Figure 1-1 System Bus Interfaces Note: Flash memories are encapsulated within the Flash Memory (FM) Module.

Any alternate functionality must be programmed. EMI is not functional in this package; since only part of the address/data bus is bonded out, use as GPIO pins. Note: Signals in italics are NOT available in the 56F8155 device. If the “State During Reset” lists more than one state for a pin, the first state is the actual reset state. Other states show the reset condition of the alternate function, which you get if the alternate pin function is selected without changing the configuration of the alternate peripheral. For example, the A8/GPIOA0 pin shows that it is tri-stated during reset. If the GPIOA_PER is changed to select the GPIO function of the pin, it will become an input if no other registers are changed.

Schmitt Input Input, pull-up enabled External Interrupt Request A and B — The IRQA and IRQB inputs are asynchronous external interrupt requests during Stop and Wait mode operation. During other operating modes, they are synchronized external interrupt requests, which indicate an external device is requesting service. They can be programmed to be level-sensitive or negative-edge triggered. To deactivate the internal pull-up resistor, set the IRQ bit in the SIM_PUDR register. See Part 6.5.6 for details. RESET 78 Schmitt Input Input, pull-up enabled Reset — This input is a direct hardware reset on the processor. When RESET is asserted low, the device is initialized and placed in the reset state. A Schmitt trigger input is used for noise immunity. The internal reset signal will be deasserted synchronous with the internal clocks after a fixed number of internal clocks. To ensure complete hardware reset, RESET and TRST should be asserted together. The only exception occurs in a debugging environment when a hardware device reset is required and the JTAG/EOnCE module must not be reset. In this case, assert RESET but do not assert TRST. Note: The internal Power-On Reset will assert on initial power-up. To deactivate the internal pull-up resistor, set the RESET bit in the SIM_PUDR register. See Part 6.5.6 for details.

To generate a reference frequency using the internal oscillator, a reference crystal or ceramic resonator must be connected between the EXTAL and XTAL pins. 3.2.1 Crystal Oscillator The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 10-15. A recommended crystal oscillator circuit is shown in Figure 3-2. Follow the crystal supplier’s recommendations when selecting a crystal, since crystal 56F8355 Technical Data, Rev. 12 34 Freescale Semiconductor Preliminary External Clock Operation parameters determine the component values required to provide maximum stability and reliable start-up. The crystal and associated components should be mounted as near as possible to the EXTAL and XTAL pins to minimize output distortion and start up stabilization time. Crystal Frequency = 4 - 8MHz (optimized for 8MHz) EXTAL XTAL Rz CLKMODE = 0 EXTAL XTAL Rz Sample External Crystal Parameters: Rz = 750 KΩ Note: If the operating temperature range is limited to below 85oC (105oC junction), then Rz = 10 Meg Ω CL1 CL2 Figure 3-2 Connecting to a Crystal Oscillator Note: The OCCS_COHL bit must be set to 1 when a crystal oscillator is used. The reset condition on the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL) register, discussed in the 56F8300 Peripheral User Manual. 3.2.2 Ceramic Resonator (Default) It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system design can tolerate the reduced signal integrity. A typical ceramic resonator circuit is shown in Figure 3-3. Refer to the supplier’s recommendations when selecting a ceramic resonator and associated components. The resonator and components should be mounted as near as possible to the EXTAL and XTAL pins.

The external clock source is connected to XTAL and the EXTAL pin is grounded. Set OCCS_COHL bit high when using an external clock source as well. XTAL External Clock EXTAL VSS Note: When using an external clocking source with this configuration, the input “CLKMODE” should be high and the COHL bit in the OSCTL register should be set to 1. Figure 3-4 Connecting an External Clock Signal Register 3.3 Registers When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the register definitions without the internal Relaxation Oscillator, since the 56F8355/56F8155 devices do NOT contain this oscillator. Part 4 Memory Map 4.1 Introduction The 56F8355 and 56F8155 devices are 16-bit motor-control chips based on the 56800E core. These parts use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip RAM and Flash memories are used in both spaces. This section provides memory maps for: • • Program Address Space, including the Interrupt Vector Table Data Address Space, including the EOnCE Memory and Peripheral Memory Maps On-chip memory sizes for each device are summarized in Table 4-1. Flash memories’ restrictions are identified in the “Use Restrictions” column of Table 4-1. 56F8355 Technical Data, Rev. 12 36 Freescale Semiconductor Preliminary Program Map Table 4-1 Chip Memory Configurations On-Chip Memory Program Flash Data Flash 56F8355 256KB 8KB 56F8155 256KB — Use Restrictions Erase/Program via Flash interface unit and word writes to CDBW Erase/Program via Flash interface unit and word writes to CDBW.

Changing MB in software will not affect Flash memory security. After reset, the OMR MA bit can be changed and will have an effect on the P-space memory map, as shown in Table 4-3. Changing the OMR MB bit will have no effect.

Setting this bit can cause unpredictable results and is not recommended, since the EMI is not functional in this package. Table 4-4 shows the memory map options of the device. The two right columns cannot be used, since the EMI pins are not provided in the package; therefore, only the Mode 0 column is relevant. Note: Program RAM is NOT available on the 56F8155 device.

Two independent program flash blocks allow one to be programmed/erased while executing from another. Each block must have its own mass erase. 4.3 Interrupt Vector Table Table 4-5 provides the reset and interrupt priority structure, including on-chip peripherals. The table is organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The priority of an interrupt can be assigned to different levels, as indicated, allowing some control over interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority level, the lowest vector number has the highest priority. The location of the vector table is determined by the Vector Base Address (VBA) register. Please see Part 5.6.11 for the reset value of the VBA. In some configurations, the reset address and COP reset address will correspond to vector 0 and 1 of the interrupt vector table. In these instances, the first two locations in the vector table must contain branch or JMP instructions. All other entries must contain JSR instructions. Note: PWMA, FlexCAN, Quadrature Decoder1, and Quad Timers B and D are NOT available on the 56F8155 device.

Setting EX = 1 is not recommended in the 56F8355/56F8155, since the EMI is not functional in this package. 5. The Data RAM is organized as a 2K x 32-bit memory to allow single-cycle, long-word operations. 4.5 Flash Memory Map Figure 4-1 illustrates the Flash Memory (FM) map on the system bus. The Flash Memory is divided into three functional blocks. The Program and boot memories reside on the Program Memory buses. They are controlled by one set of banked registers. Data Memory Flash resides on the Data Memory buses and is controlled separately by its own set of banked registers. The top nine words of the Program Memory Flash are treated as special memory locations. The content of these words is used to control the operation of the Flash Controller. Because these words are part of the Flash Memory content, their state is maintained during power-down and reset. During chip initialization, the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash Memory chapter of the 56F8300 Peripheral User Manual. These configuration parameters are located between $01_FFF7 and $01_FFFF.

Programmed Memory The Boot Flash memory block is programmed during manufacturing with a default Serial Bootloader program. The Serial Bootloader application can be used to load a user application into the Program and Data Flash (NOT available in the 56F8155) memories of the device. The 56F83xx SCI/CAN Bootloader User Manual (MC56F83xxBLUM) provides detailed information on this firmware. An application note, Production Flash Programming (AN1973), details how the Serial Bootloader program can be used to perform production Flash programming of the on board flash memories as well as other potential methods. Like all the Flash memory blocks, the Boot Flash can be erased and programmed by the user. The Serial Bootloader application is programmed as an aid to the end user, but is not required to be used or maintained in the Boot Flash memory. Part 5 Interrupt Controller (ITCN) 5.1 Introduction The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to signal to the 56800E core when an interrupt of sufficient priority exists, and to what address to jump in order to service this interrupt. 5.2 Features The ITCN module design includes these distinctive features: 56F8355 Technical Data, Rev. 12 72 Freescale Semiconductor Preliminary Functional Description • • • • Programmable priority levels for each IRQ Two programmable Fast Interrupts Notification to SIM module to restart clocks out of Wait and Stop modes Drives initial address on the address bus after reset For further information, see Table 4-5, Interrupt Vector Table Contents. 5.3 Functional Description The Interrupt Controller is a slave on the IPBus. It contains registers allowing each of the 82 interrupt sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. Next, all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the active interrupt requests for that level. Within a given priority level, 0 is the highest priority, while number 81 is the lowest. 5.3.1 Normal Interrupt Handling Once the ITCN has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. Normal interrupt handling concatenates the VBA and the vector number to determine the vector address. In this way, an offset is generated into the vector table for each interrupt. 5.3.2 Interrupt Nesting Interrupt exceptions may be nested to allow an IRQ of higher priority than the current exception to be serviced. The following tables define the nesting requirements for each priority level. Table 5-1 Interrupt Mask Bit Definition SR[9]1 0 0 1 1 SR[8]1 0 1 0 1 Permitted Exceptions Priorities 0, 1, 2, 3 Priorities 1, 2, 3 Priorities 2, 3 Priority 3 Masked Exceptions None Priority 0 Priorities 0, 1 Priorities 0, 1, 2 1. Core status register bits indicating current interrupt mask within the core. Table 5-2 Interrupt Priority Encoding IPIC_LEVEL[1:0]1 00 01 10 Current Interrupt Priority Level No Interrupt or SWILP Priority 0 Priority 1 Required Nested Exception Priority Priorities 0, 1, 2, 3 Priorities 1, 2, 3 Priorities 2, 3 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 73 Table 5-2 Interrupt Priority Encoding IPIC_LEVEL[1:0]1 11 Current Interrupt Priority Level Priorities 2 or 3 Required Nested Exception Priority Priority 3 1. See IPIC field definition in Part 5.6.30.2 5.3.3 Fast Interrupt Handling Fast interrupts are described in the DSP56800E Reference Manual. The interrupt controller recognizes fast interrupts before the core does. A fast interrupt is defined (to the ITCN) by: 1. Setting the priority of the interrupt as level 2, with the appropriate field in the IPR registers 2. Setting the FIMn register to the appropriate vector number 3. Setting the FIVALn and FIVAHn registers with the address of the code for the fast interrupt When an interrupt occurs, its vector number is compared with the FIM0 and FIM1 register values. If a match occurs, and it is a level 2 interrupt, the ITCN handles it as a fast interrupt. The ITCN takes the vector address from the appropriate FIVALn and FIVAHn registers, instead of generating an address that is an offset from the VBA. The core then fetches the instruction from the indicated vector adddress and if it is not a JSR, the core starts its fast interrupt handling. 56F8355 Technical Data, Rev. 12 74 Freescale Semiconductor Preliminary Block Diagram 5.4 Block Diagram Priority Level Level 0 82 -> 7 Priority Encoder any0 7 INT1 2 -> 4 Decode INT VAB CONTROL IPIC Level 3 Priority Level 82 -> 7 Priority Encoder any3 IACK SR[9:8] 7 PIC_EN INT82 2 -> 4 Decode Figure 5-1 Interrupt Controller Block Diagram 5.5 Operating Modes The ITCN module design contains two major modes of operation: • • Functional Mode The ITCN is in this mode by default. Wait and Stop Modes During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN will signal a pending IRQ to the System Integration Module (SIM) to restart the clocks and service the IRQ. An IRQ can only wake up the core if the IRQ is enabled prior to entering the Wait or Stop mode. Also, the IRQA and IRQB signals automatically become low-level sensitive in these modes even if the control register bits are set to make them falling-edge sensitive. This is because there is no clock available to detect the falling edge. A peripheral which requires a clock to generate interrupts will not be able to generate interrupts during Stop mode. The FlexCAN module can wake the device from Stop mode, and a reset will do just that, or IRQA and IRQB can wake it up. 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 75 5.6 Register Descriptions A register address is the sum of a base address and an address offset. The base address is defined at the system level and the address offset is defined at the module level. The ITCN peripheral has 24 registers.

It controls distribution of resets and clocks and provides a number of control features. The system integration module is responsible for the following functions: • • • • • • • Reset sequencing Clock generation & distribution Stop/Wait control Pull-up enables for selected peripherals System status registers Registers for software access to the JTAG ID of the chip Enforcing Flash security These are discussed in more detial in the sections that follow. 6.2 Features The SIM has the following features: • • • Flash security feature prevents unauthorized access to code/data contained in on-chip Flash memory Power-saving clock gating for peripheral Three power modes (Run, Wait, Stop) to control power utilization — Stop mode shuts down the 56800E core, system clock, peripheral clock, and PLL operation — Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart); must be explicitly done — Wait mode shuts down 56800E core and unnecessary system clock operation — Run mode supports full part operation • • • • • • • Controls to enable/disable the 56800E core WAIT and STOP instructions Calculates base delay for reset extension based upon POR or RESET operations. Reset delay will be 3 x 32 clocks (phased release of reset) for reset, except for POR, which is 221 clock cycles. Controls reset sequencing after reset Software-initiated reset Four 16-bit registers reset only by a Power-On Reset usable for general-purpose software control System Control Register Registers for software access to the JTAG ID of the chip 6.3 Operating Modes Since the SIM is responsible for distributing clocks and resets across the chip, it must understand the 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 103 various chip operating modes and take appropriate action. These are: • Reset Mode, which has two submodes: — POR and RESET operation The 56800E core and all peripherals are reset. This occurs when the internal POR is asserted or the RESET pin is asserted. — COP reset and software reset operation The 56800E core and all peripherals are reset. The MA bit within the OMR is not changed. This allows the software to determine the boot mode (internal or external boot) to be used on the next reset. • • Run Mode This is the primary mode of operation for this device. In this mode, the 56800E controls chip operation Debug Mode The 56800E is controlled via JTAG/EOnCE when in debug mode. All peripherals, except the COP and PWMs, continue to run. COP is disabled and PWM outputs are optionally switched off to disable any motor from being driven; see the PWM chapter in the 56F8300 Peripheral User Manual for details. Wait Mode In Wait mode, the core clock and memory clocks are disabled. Optionally, the COP can be stopped. Similarly, it is an option to switch off PWM outputs to disable any motor from being driven. All other peripherals continue to run. Stop Mode When in Stop mode, the 56800E core, memory and most peripheral clocks are shut down. Optionally, the COP and CAN can be stopped. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. The CAN (along with any non-gated interrupt) is capable of waking the chip up from Stop mode, but is not fully functional in Stop mode. • • 6.4 Operating Mode Register Bit Type RESET 15 NL R/W 0 0 0 0 0 0 0 14 13 12 11 10 9 8 CM R/W 0 7 XP R/W 0 6 SD R/W 0 5 R R/W 0 4 SA R/W 0 3 EX R/W 0 2 0 0 1 MB R/W X 0 MA R/W X Figure 6-1 OMR The reset state for MB and MA will depend on the Flash secured state.

Pins which can operate as GPIO can have these resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the appropriate bit in this register. Disabling pull-ups is done on a peripheral-by-peripheral basis (for pins not muxed with GPIO). Each bit in the register (see Figure 6-8) corresponds to a functional group of pins. See Table 2-2 to identify which pins can deactivate the internal pull-up resistor. 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 109 Base + $8 Read Write RESET 15 0 14 PWMA1 0 13 CAN 0 12 EMI_ MODE 0 11 RESET 0 10 IRQ 0 9 XBOOT 0 8 7 6 0 5 CTRL 0 4 0 3 JTAG 0 2 0 1 0 0 0 PWMB PWMA0 0 0 0 0 0 0 0 0 Figure 6-8 SIM Pull-up Disable Register (SIM_PUDR) 6.5.6.1 6.5.6.2 6.5.6.3 6.5.6.4 Note: Reserved—Bit 15 PWMA1—Bit 14 CAN—Bit 13 EMI_MODE—Bit 12 In this package, this input pin is double-bonded with the adjacent VSS pin and this bit should be changed to a 1 in order to reduce power consumption.

The default value is SYS_CLK. This path has been optimized in order to minimize any delay and clock duty cycle distortion. All other clocks primarily muxed out are for test purposes only, and are subject to significant phase shift at high frequencies. The upper four bits of the GPIOB register can function as GPIO, A[23:20], or as additional clock output signals. GPIO has priority and is enabled/disabled via the GPIOB_PER. If GPIOB[7:4] are programmed to operate as peripheral outputs, then the choice between A[23:20] and additional clock outputs is done here in the CLKOSR. The default state is for the peripheral function of GPIOB[7:4] to be programmed as A[23:20]. This can be changed by altering A[23:20], as shown in Figure 6-9.

The default peripheral is Quad Decoder 1 and Quad Decoder 1, (NOT available in the 56F8155 device); these peripherals work together. The four I/O pins associated with GPIOC can function as GPIO, Quad Decoder 1/Quad Decoder 1, or as SPI 1 signals. GPIO is not the default and is enabled/disabled via the GPIOC_PER, as shown in 56F8355 Technical Data, Rev. 12 112 Freescale Semiconductor Preliminary Register Descriptions Figure 6-10 and Table 6-2. When GPIOC[3:0] are programmed to operate as peripheral I/O, then the choice between decoder/timer and SPI inputs/outputs is made in the SIM_GPS register and in conjunction with the Quad Timer Status and Control Registers (SCR). The default state is for the peripheral function of GPIOC[3:0] to be programmed as decoder functions. This can be changed by altering the appropriate controls in the indicated registers.

The I/O short address mode allows the instruction to specify the lower six bits of address; the upper address bits are not directly controllable. This register set allows limited control of the full address, as shown in Figure 6-13. Note: If this register is set to something other than the top of memory (EOnCE register space) and the EX bit in the OMR is set to 1, the JTAG port cannot access the on-chip EOnCE registers, and debug functions will be affected. “Hard Coded” Address Portion 6 Bits from I/O Short Address Mode Instruction Instruction Portion 16 Bits from SIM_ISALL Register 2 Bits from SIM_ISALH Register Full 24-Bit for Short I/O Address Figure 6-13 I/O Short Address Determination With this register set, an interrupt driver can set the SIM_ISALL register pair to point to its peripheral registers and then use the I/O Short addressing mode to reference them.

The maximum master clock frequency is 120MHz. Peripheral and system clocks are generated at half the master clock frequency and therefore at a maximum 60MHz. The SIM provides power modes (Stop, Wait) and clock enables (SIM_PCE register, CLK_DIS, ONCE_EBL) to control which clocks are in operation. The OCCS, power modes, and clock enables provide a flexible means to manage power consumption. Power utilization can be minimized in several ways. In the OCCS, crystal oscillator, and PLL may be shut down when not in use. When the PLL is in use, its prescaler and postscaler can be used to limit PLL and master clock frequency. Power modes permit system and/or peripheral clocks to be disabled when unused. Clock enables provide the means to disable individual clocks. Some peripherals provide further controls to disable unused subfunctions. Refer to Part 3 On-Chip Clock Synthesis (OCCS), and the 56F8300 Peripheral User Manual for further details. 6.7 Power Down Modes Overview The 56F8355/56F8155 operate in one of three power-down modes, as shown in Table 6-3. 56F8355 Technical Data, Rev. 12 118 Freescale Semiconductor Preliminary Stop and Wait Mode Disable Function Table 6-3 Clock Operation in Power-Down Modes Mode Run Wait Core Clocks Active Core and memory clocks disabled Peripheral Clocks Active Active Description Device is fully functional Peripherals are active and can produce interrupts if they have not been masked off. Interrupts will cause the core to come out of its suspended state and resume normal operation. Typically used for power-conscious applications. The only possible recoveries from Stop mode are: 1. CAN traffic (1st message will be lost) 2. Non-clocked interrupts 3. COP reset 4. External reset 5. Power-on reset Stop System clocks continue to be generated in the SIM, but most are gated prior to reaching memory, core and peripherals. All peripherals, except the COP/watchdog timer, run off the IPBus clock frequency, which is the same as the main processor frequency in this architecture. The maximum frequency of operation is SYS_CLK = 60MHz. 6.8 Stop and Wait Mode Disable Function Permanent Disable D D-FLOP Q C 56800E Reprogrammable Disable D Q STOP_DIS D-FLOP Clock Select Reset C R Note: Wait disable circuit is similar Figure 6-16 Stop Disable Circuit The 56800E core contains both STOP and WAIT instructions. Both put the CPU to sleep. For lowest 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 119 power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. When the PLL is shut down, the 56800E system clock must be set equal to the oscillator output. Some applications require the 56800E STOP and WAIT instructions to be disabled. To disable those instructions, write to the SIM control register (SIM_CONTROL), described in Part 6.5.1. This procedure can be on either a permanent or temporary basis. Permanently assigned applications last only until their next reset. 6.9 Resets The SIM supports four sources of reset. The two asynchronous sources are the external RESET pin and the Power-On Reset (POR). The two synchronous sources are the software reset, which is generated within the SIM itself by writing to the SIM_CONTROL register, and the COP reset. Reset begins with the assertion of any of the reset sources. Release of reset to various blocks is sequenced to permit proper operation of the device. A POR reset is first extended for 221 clock cycles to permit stabilization of the clock source, followed by a 32 clock window in which SIM clocking is initiated. It is then followed by a 32 clock window in which peripherals are released to implement Flash security, and, finally, followed by a 32 clock window in which the core is initialized. After completion of the described reset sequence, application code will begin execution. Resets may be asserted asynchronously, but are always released internally on a rising edge of the system clock. Part 7 Security Features The 56F8355/56F8155 offer security features intended to prevent unauthorized users from reading the contents of the Flash Memory (FM) array. The Flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the Flash array. However, part of the security must lie with the user’s code. An extreme example would be user’s code that dumps the contents of the internal program, as this code would defeat the purpose of security. At the same time, the user may also wish to put a “backdoor” in his program. As an example, the user downloads a security key through the SCI, allowing access to a programming routine that updates parameters stored in another section of the Flash. 56F8355 Technical Data, Rev. 12 120 Freescale Semiconductor Preliminary Operation with Security Enabled 7.1 Operation with Security Enabled Once the user has programmed the Flash with his application code, the device can be secured by programming the security bytes located in the FM configuration field, which occupies a portion of the FM array. These non-volatile bytes will keep the part secured through reset and through power-down of the device. Only two bytes within this field are used to enable or disable security. Refer to the Flash Memory section in the 56F8300 Peripheral User Manual for the state of the security bytes and the resulting state of security. When Flash security mode is enabled in accordance with the method described in the Flash Memory module specification, the device will disable the core EOnCE debug capabilities. Normal program execution is otherwise unaffected. 7.2 Flash Access Blocking Mechanisms The 56F8355/56F8155 have several operating functional and test modes. Effective Flash security must address operating mode selection and anticipate modes in which the on-chip Flash can be compromised and read without explicit user permission. Methods to block these are outlined in the next subsections. 7.2.1 • • Forced Operating Mode Selection Unsecured Mode Secure Mode (EOnCE disabled) At boot time, the SIM determines in which functional modes the device will operate. These are: When Flash security is enabled as described in the Flash Memory module specification, the device will disable the EOnCE debug interface. 7.2.2 Disabling EOnCE Access On-chip Flash can be read by issuing commands across the EOnCE port, which is the debug interface for the 56800E core. The TRST, TCLK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the device boots, the chip-level JTAG TAP (Test Access Port) is active and provides the chip’s boundary scan capability and access to the ID register. Proper implementation of Flash security requires that no access to the EOnCE port is provided when security is enabled. The 56800E core has an input which disables reading of internal memory via the JTAG/EOnCE. The FM sets this input at reset to a value determined by the contents of the FM security bytes. 7.2.3 Flash Lockout Recovery If a user inadvertently enables Flash security on the device, a built-in lockout recovery mechanism can be used to reenable access to the device. This mechanism completely reases all on-chip Flash, thus disabling Flash security. Access to this recovery mechanism is built into CodeWarrior via an instruction in memory configuration (.cfg) files. Add, or uncomment the following configuration command: 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 121 unlock_flash_on_connect 1 For more information, please see CodeWarrior MC56F83xx/DSP5685x Family Targeting Manual. The LOCKOUT_RECOVERY instruction has an associated 7-bit Data Register (DR) that is used to control the clock divider circuit within the FM module. This divider, FM_CLKDIV[6:0], is used to control the period of the clock used for timed events in the FM erase algorithm. This register must be set with appropriate values before the lockout sequence can begin. Refer to the JTAG section of the 56F8300 Peripheral User Manual for more details on setting this register value. The value of the JTAG FM_CLKDIV[6:0] will replace the value of the FM register FMCLKD that divides down the system clock for timed events, as illustrated in Figure 7-1. FM_CLKDIV[6] will map to the PRDIV8 bit, and FM_CLKDIV[5:0] will map to the DIV[5:0] bits. The combination of PRDIV8 and DIV must divide the FM input clock down to a frequency of 150kHz-200kHz. The “Writing the FMCLKD Register” section in the Flash Memory chapter of the 56F8300 Peripheral User Manual gives specific equations for calculating the correct values. Flash Memory SYS_CLK 2 input clock 7 FMCLKD 7 FM_CLKDIV JTAG FM_ERASE 7 DIVIDER Figure 7-1 JTAG to FM Connection for Lockout Recovery Two examples of FM_CLKDIV calculations follow. EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been set up, the input clock will be below 12.8MHz, so PRDIV8 = FM_CLKDIV[6] = 0. Using the following equation yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a clock of 190kHz. This translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively. 56F8355 Technical Data, Rev. 12 122 Freescale Semiconductor Preliminary Flash Access Blocking Mechanisms 150[kHz] < ( SYS_CLK (2) (DIV + 1) ) < 200[kHz] EXAMPLE 2: In this example, the system clock has been set up with a value of 32MHz, making the FM input clock 16MHz. Because that is greater than 12.8MHz, PRDIV8 = FM_CLKDIV[6] = 1. Using the following equation yields a DIV value of 9 for a clock of 200kHz, and a DIV value of 10 for a clock of 181kHz. This translates to an FM_CLKDIV[6:0] value of $49 or $4A, respectively. 150[kHz] < ( SYS_CLK (2) (DIV + 1) ) < 200[kHz] Once the LOCKOUT_RECOVERY instruction has been shifted into the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. After the data register has been updated, the user must transition the TAP controller into the RUN-TEST/IDLE state for the lockout sequence to commence. The controller must remain in this state until the erase sequence has completed. For details, see the JTAG Section in the 56F8300 Peripheral User Manual. Note: When the lockout recovery sequence has completed, the user must reset both the JTAG TAP controller (by asserting TRST) and the device (by asserting external chip reset) to return to normal unsecured operation. 7.2.4 Product Analysis The recommended method of unsecuring a programmed device for product analysis of field failures is via the backdoor key access. The customer would need to supply Technical Support with the backdoor key and the protocol to access the backdoor routine in the Flash. Additionally, the KEYEN bit that allows backdoor key access must be set. An alternative method for performing analysis on a secured hybrid controller would be to mass-erase and reprogram the Flash with the original code, but modify the security bytes. 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 123 To insure that a customer does not inadvertently lock himself out of the device during programming, it is recommended that he program the backdoor access key first, his application code second, and the security bytes within the FM configuration field last. Part 8 General Purpose Input/Output (GPIO) 8.1 Introduction This section is intended to supplement the GPIO information found in the 56F8300 Peripheral User Manual and contains only chip-specific information. This information supercedes the generic information in the 56F8300 Peripheral User Manual. 8.2 Memory Maps The width of the GPIO port defines how many bits are implemented in each of the GPIO registers. Based on this and the default function of each of the GPIO pins, the reset values of the GPIOx_PUR and GPIOx_PER registers will change from port to port. Tables 4-29 through 4-34 define the actual reset values of these registers for these devices. 8.3 Configuration There are six GPIO ports defined on the 56F8355/56F8155. The width of each port and the associated peripheral function is shown in Table 8-1 and Table 8-2. The specific mapping of GPIO port pins is shown in Table 8-2.

The term “5V-tolerant” refers to the capability of an I/O pin, built on a 3.3V-compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture 56F8355 Technical Data, Rev. 12 Freescale Semiconductor Preliminary 129 of devices designed for 3.3V and 5V power supplies. In such sytems, a bus may carry both 3.3V- and 5V-compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V ± 10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings of 3.3V I/O levels combined with the ability to receive 5V levels without damage. Absolute maximum ratings in Table 10-1 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. Note: All specifications meet both Automotive and Industrial requirements unless individual specifications are listed. Note: The 56F8155 device is guaranteed to 40MHz and specified to meet Industrial requirements only. CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. Note: The 56F8155 device is specified to meet Industrial requirements only; CAN is NOT available on the 56F8155 device.

Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application. Determined on 2s2p thermal test board. 2. Junction to ambient thermal resistance, Theta-JA (RθJA) was simulated to be equivalent to the JEDEC specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was also simulated on a thermal test board with two internal planes (2s2p where “s” is the number of signal layers and “p” is the number of planes) per JESD51-6 and JESD51-7. The correct name for Theta-JA for forced convection or with the non-single layer boards is Theta-JMA. 3. Junction to case thermal resistance, Theta-JC (RθJC ), was simulated to be equivalent to the measured values using the cold plate technique with the cold plate temperature used as the "case" temperature. The basic cold plate measurement technique is described by MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when the package is being used with a heat sink. 4. Thermal Characterization Parameter, Psi-JT (ΨJT ), is the "resistance" from junction to reference point thermocouple on top center of case as defined in JESD51-2. ΨJT is a useful value to use to estimate junction temperature in steady state customer environments. 5. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance. 6. See Part 12.1 for more details on thermal design considerations. 7.
