SPRS668C – APRIL 2010 – REVISED JUNE 2011
Description
Developers can now deliver crystal clear multi-format video at up to 1080p H.264 at 30fps (encode and
closed-looped decode) in their digital video designs without concerns of video format support, constrained
network bandwidth, limited system storage capacity or cost with the new TMS320DM368 DaVinci™ video
processors from Texas Instruments Incorporated (TI).
The DM368 is capable of achieving HD video processing at 1080p 30fps H.264 and is completely
pin-to-pin compatible with the DM365 processors, using the same ARM926EJ-S core running at 432 MHz.
This ARM9-based DM368 device supports production-qualified H.264BP/MP/HP, MPEG-4, MPEG-2,
MJPEG and VC1/WMV9 codecs providing customers with the flexibility to select the right video codec for
their application. These codecs run on independent coprocessors (HDVICP and MJCP) offloading all
compression needs from the main ARM core. This allows developers to obtain optimal performance from
the ARM for their applications, including their multi-channel, multi-stream and multi-format needs.
Video surveillance designers achieve greater compression efficiency to provide more storage without
straining the network bandwidth. Developers of media playback and camera-driven applications, such as
video doorbells, digital signage, digital video recorders, portable media players and more can take
advantage of the low power consumption and can ensure interoperability, as well as product scalability by
taking advantage of the full suite of codecs supported on the DM368.
Along with multi-format HD video, the DM368 also features a suite of peripherals saving developers on
system cost and complexity to enable a seamless interface to most additional external devices required
for video applications. The image sensor interface is flexible enough to support CCD, CMOS, and various
other interfaces such as BT.656, BT1120. The DM368 also offers a high level of integration with HD
display support, including three built-in 10-bit HD analog video digital-to-analog converters (DACs),
DDR2/mDDR, Ethernet MAC, USB 2.0, integrated audio, host port interface (HPI), analog-to digital
converter and many more features saving developers on overall system costs, as well as real estate on
their circuit boards allowing for a slimmer, sleeker design.

2.3
ARM Subsystem Overview
The ARM Subsystem contains components required to provide the ARM926EJ-S (ARM) master control of
the overall device system, including the components of the ARM Subsystem, the peripherals, and the
external memories.
The ARM is responsible for handling system functions such as system-level initialization, configuration,
user interface, user command execution, connectivity functions, interface and control of the subsystem,
etc. The ARM is master and performs these functions because it has a large program memory space and
fast context switching capability, and is thus suitable for complex, multi-tasking, and general-purpose
control tasks.
2.3.1
Components of the ARM Subsystem
The ARM Subsystem consists of the following components:
• ARM926EJ-S RISC processor, including:
– coprocessor 15 (CP15)
– MMU
– 16KB Instruction cache
– 8KB Data cache
– Write Buffer
– Java accelerator
• ARM Internal Memories
– 32KB Internal RAM (32-bit wide access)
– 16KB Internal ROM (ARM bootloader for non-AEMIF boot modes)
• Embedded Trace Module and Embedded Trace Buffer (ETM/ETB)
• System Control Peripherals
– ARM Interrupt Controller
– PLL Controller
– Power and Sleep Controller
– System Control Module
The ARM also manages/controls all the device peripherals.
Figure 2-1 shows the functional block diagram of the ARM Subsystem.

ARM926EJ-S RISC CPU
The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of
ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications
where full memory management, high performance, low die size, and low power are all important. The
ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to
trade off between high performance and high code density. Specifically, the ARM926EJ-S processor
supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes,
providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code
overhead.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both
hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a
complete high performance subsystem, including:
• ARM926EJ -S integer core
• CP15 system control coprocessor
• Memory Management Unit (MMU)
• Separate instruction and data Caches
• Write buffer
• Separate instruction and data Tightly-Coupled Memories (TCMs) [internal RAM] interfaces
• Separate instruction and data AHB bus interfaces
• Embedded Trace Module and Embedded Trace Buffer (ETM/ETB)
For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available

CP15
The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and
data caches, Tightly-Coupled Memories (TCMs), Memory Management Unit (MMU), and other ARM
subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions,
when the ARM in a privileged mode such as supervisor or system mode.
2.3.4
MMU
The ARM926EJ-S MMU provides virtual memory features required by operating systems such as Linux,
WindowCE, ultron, ThreadX, etc. A single set of two level page tables stored in main memory is used to
control the address translation, permission checks and memory region attributes for both data and
instruction accesses. The MMU uses a single unified Translation Lookaside Buffer (TLB) to cache the
information held in the page tables. The MMU features are:
• Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.
• Mapping sizes are:
– 1MB (sections)
– 64KB (large pages)
– 4KB (small pages)
– 1KB (tiny pages)
• Access permissions for large pages and small pages can be specified separately for each quarter of
the page (subpage permissions)
• Hardware page table walks
• Invalidate entire TLB, using CP15 register 8
• Invalidate TLB entry, selected by MVA, using CP15 register 8
• Lockdown of TLB entries, using CP15 register 10
2.3.5
Caches and Write Buffer
The size of the Instruction Cache is 16KB, Data cache is 8KB. Additionally, the Caches have the following
features:
• Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)
• Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with
two dirty bits in the Dcache
• Dcache supports write-through and write-back (or copy back) cache operation, selected by memory
region using the C and B bits in the MMU translation tables.
• Critical-word first cache refilling
• Cache lockdown registers enable control over which cache ways are used for allocation on a line fill,
providing a mechanism for both lockdown, and controlling cache corruption
• Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG
RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the
TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the
possibility of TLB misses related to the write-back address.
• Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of
the Dcache or Icache, and regions of virtual memory.
The write buffer is used for all writes to a noncachable bufferable region, write-through region and write
misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for
cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a
four-address buffer. The Dcache write-back has eight data word entries and a single address entry.

instructions on the D-TCM bus or data on the I-TCM bus, an arbiter is included so that both data and
instructions can be stored in the internal RAM/ROM. The arbiter also allows accesses to the RAM/ROM
from extra-ARM sources (e.g., EDMA or other masters). The ARM926EJ-S has built-in DMA support for
direct accesses to the ARM internal memory from a non-ARM master. Because of the time-critical nature
of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA
transfers.
Instruction and Data accesses are differentiated via accessing different memory map regions, with the
instruction region from 0x0000 through 0x7FFF and data from 0x10000 through 0x17FFF. Placing the
instruction region at 0x0000 is necessary to allow the ARM Interrupt Vector table to be placed at 0x0000,
as required by the ARM architecture. The internal 32-KB RAM is split into two physical banks of 16KB
each, which allows simultaneous instruction and data accesses to be accomplished if the code and data
are in separate banks.
2.3.7
Advanced High-performance Bus (AHB)
The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the configuration bus
and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB
by the configuration bus and the external memories bus.
2.3.8
Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)
To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an
Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem also includes the Embedded Trace
Buffer (ETB). The ETM consists of two parts:
• Trace Port provides real-time trace capability for the ARM9.
• Triggering facilities provide trigger resources, which include address and data comparators, counter,
and sequencers.
The device trace port is not pinned out and is instead only connected to the Embedded Trace Buffer. The
ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace
data.
2.3.9
ARM Memory Mapping
The ARM memory map is shown in Table 2-3 and Table 2-4. This section describes the memories and
interfaces within the ARM's memory map.
2.3.9.1
ARM Internal Memories
The ARM has access to the following ARM internal memories:
• 32KB ARM Internal RAM on TCM interface, logically separated into two 16KB pages to allow
simultaneous access on any given cycle if there are separate accesses for code (I-TCM bus) and data
(D-TCM) to the different memory regions.
• 16KB ARM Internal ROM
2.3.9.2
External Memories
The ARM has access to the following External memories:
• DDR2 / mDDR Synchronous DRAM
• Asynchronous EMIF / OneNAND / NOR
• NAND Flash

2.3.10 Peripherals
The ARM has access to all of the peripherals on the device.
2.3.11 ARM Interrupt Controller (AINTC)
The device ARM Interrupt Controller (AINTC) has the following features:
• Supports up to 64 interrupt channels (16 external channels)
• Interrupt mask for each channel
• Each interrupt channel can be mapped to a Fast Interrupt Request (FIQ) or to an Interrupt Request
(IRQ) type of interrupt.
• Hardware prioritization of simultaneous interrupts
• Configurable interrupt priority (2 levels of FIQ and 6 levels of IRQ)
• Configurable interrupt entry table (FIQ and IRQ priority table entry) to reduce interrupt processing time
The ARM core supports two interrupt types: FIQ and IRQ. See the ARM926EJ-S Technical Reference
Manual for detailed information about the ARM’s FIQ and IRQ interrupts. Each interrupt channel is
mappable to an FIQ or to an IRQ type of interrupt, and each channel can be enabled or disabled. The
INTC supports user-configurable interrupt-priority and interrupt entry addresses. Entry addresses minimize
the time spent jumping to interrupt service routines (ISRs). When an interrupt occurs, the corresponding
highest priority ISR’s address is stored in the INTC’s ENTRY register. The IRQ or FIQ interrupt routine can
read the ENTRY register and jump to the corresponding ISR directly. Thus, the ARM does not require a
software dispatcher to determine the asserted interrupt.
2.4
System Control Module
The system control module is a system-level module containing status and top-level control logic required
by the device. The system control module consists of a miscellaneous set of status and control registers,
accessible by the ARM and supporting all of the following system features and operations:
• Device identification
• Device configuration
– Pin multiplexing control
– Device boot configuration status
• ARM interrupt and EDMA event multiplexing control
• Special peripheral status and control
– Timer64
– USB PHY control
– VPSS clock and video DAC control and status
– DDR VTP control
– Clockout circuitry
– GIO de-bounce control
• Power management
– Deep sleep
• Bandwidth Management
– Bus master DMA priority control
For more information on the System Control Module refer to Section 3, Device Configurations and the
TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).

Power Management
The device is designed for minimal power consumption. There are two components to power
consumption: active power and leakage power. Active power is the power consumed to perform work and
scales with clock frequency and the amount of computations being performed. Active power can be
reduced by controlling the clocks in such a way as to either operate at a clock setting just high enough to
complete the required operation in the required time-line or to run at a clock setting until the work is
complete and then drastically cut the clocks (e.g. to PLL Bypass mode) until additional work must be
performed. Leakage power is due to static current leakage and occurs regardless of the clock rate.
Leakage, or standby power, is unavoidable while power is applied and scales roughly with the operating
junction temperatures. Leakage power can only be avoided by removing power completely from a device
or subsystem. The device includes several power management modes which are briefly described in
Table 2-2. See the TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number
SPRUFG5) for more information on power management.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
Specifies the operating I/O supply voltage for each signal. See Section 6.3
, Power Supplies for more detail.
PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 kΩ resistor should be used.)
To reduce EMI and reflections, depending on the trace length, approximately 22 Ω to 50 Ω damping resistors are recommend on the
following outputs placed near the device: YOUT(0-7),COUT(0-7), HSYNC,VSYNC,LCD_OE,FIELD, and,VCLK. The trace lengths should
be minimized.
The Y input (YIN[7:0]) and C input (CIN[7:0]) buses can be swapped by programming the field bit YCINSWP in the VPFE CCD
Configuration (CCDCFG) register (0x01C7 0136h).
IF YCINSWP bit is 0 (default) YIN[7:0] = Y signal / CIN[7:0] = C signal .
IF YCINSWP bit is 1 YIN[7:0] = C signal / CIN[7:0] = Y signal

(14) The Y output (YOUT[7:0]) and C output (COUT[7:0]) buses can be swapped by programming the field bit YCOUTSWP in the VPFE
CCD Configuration (CCDCFG) register (0x01C7 0136h). If the YCOUTSWP bit is 0 (default), YOUT[7:0] = Y signal / COUT[7:0] = C
signal . If the YCOUTSWP bit is 1, YOUT[7:0] = C signal / COUT[7:0] = Y signal. For more information, see the TMS320DM36x Video
Processing Front End (VPFE) Reference Guide (literature number SPRUFG8).
(15) To reduce EMI and reflections, depending on the trace length, approximately 22 Ω to 50 Ω damping resistors are recommend on the
following outputs placed near the device: YOUT(0-7),COUT(0-7), HSYNC,VSYNC,LCD_OE,FIELD, and,VCLK. The trace lengths should
be minimized.

USB operating mode identification pin.
For device mode operation only, pull up this pin to
VDD with a 1.5K ohm resistor.
For host mode operation only, pull down this pin to
ground (VSS) with a 1.5K ohm resistor.
If using an OTG or mini-USB connector, this pin will
be set properly via the cable/connector configuration.
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to 3.3V.
USB_VBUS

A I/O

USB_VBUS
This pin is used by the USB Controller to detect a
presence of 5V power (4.4V is the threshold) on the
USB_VBUS line for normal operation. This power is
sourced by the USB Component that is assuming the
role of a Host. In other words, the power on the
USB_VBUS line is not sourced by the Device. From
DM368 perspective, when operating as a Host, it
ensures that the external power supply that the
DM368 has sourced is within the required voltage
level (>= 4.4V) and when DM368 is operating as a
Device, the presence of a 5V power on the VBUS
Line is used to signify the presence of an external
Host.
Note 1: When the DM368 is operating as a Device, it
uses the power on the USB_VBUS line to power up
its internal pull-up resistor on the D+ line.

Device Support
Development Tools
TI offers an extensive line of development tools for device systems, including tools to evaluate the
performance of the processors, generate code, develop algorithm implementations, and fully integrate and
debug software and hardware modules. The tools support documentation is electronically available within
the Code Composer Studio™ Integrated Development Environment (IDE).
The following products support development of device based applications:
Software Development Tools:
Code Composer Studio™ Integrated Development Environment (IDE): including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Hardware Development Tools:
Extended Development System (XDS™) Emulator (supports TMS320DM368 DMSoC multiprocessor
system debug) EVM (Evaluation Module)
For a complete listing of development-support tools for the TMS320DM368 DMSoC platform, visit the
Texas Instruments web site on the Worldwide Web at www.ti.com. For information on pricing and
availability, contact the nearest TI field sales office or authorized distributor.
2.9.2
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX,
TMP, or TMS (e.g., ). Texas Instruments recommends two of three possible prefix designators for its
support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX
Experimental device that is not necessarily representative of the final device's electrical
specifications.
TMP
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
TMS
Fully-qualified production device.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully qualified development-support product.
TMX and TMP devices and TMDX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate is undefined. Only qualified production devices are to
be used in production.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, ZCE), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, 202 is 202.5 MHz). The

3.2
Boot Modes
The ARM can boot from either Asynchronous EMIF (OneNand/NOR) or from ARM ROM, as determined
by the setting of the device configuration pins BTSEL[2:0]. The boot selection pins (BTSEL[2:0]) determine
the ARM boot process. After reset (POR, warm reset, or max reset), ARM program execution begins in
ARM ROM at 0x0000: 8000, except when BTSEL[2:0] = 001, indicating AEMIF (OneNand/NOR) flash
boot.
3.2.1
Boot Modes Overview
The ARM ROM boot loader (RBL) executes when the BTSEL[2:0] pins indicate a condition other than the
normal ARM EMIF boot.
• If BTSEL[2:0] = 001 - Asynchronous EMIF boot mode (NOR or OneNAND). This mode is handled by
hardware control and does not involve the ROM. In the case of OneNAND, the user is responsible for
putting any necessary boot code in the OneNAND's boot page. This code shall configure the AEMIF
module for the OneNAND device. After the AEMIF module is configured, booting will continue
immediately after the OneNAND’s boot page with the AEMIF module managing pages thereafter.
• The RBL supports 7 distinct boot modes:
– BTSEL[2:0] = 000 - NAND Boot mode
– BTSEL[2:0] = 010 - MMC0/SD0 Boot mode
– BTSEL[2:0] = 011 - UART0 Boot mode
– BTSEL[2:0] = 100 - USB Boot mode
– BTSEL[2:0] = 101 - SPI0 Boot mode
– BTSEL[2:0] = 110 - EMAC Boot mode
– BTSEL[2:0] = 111 - HPI Boot mode
• If NAND boot fails, then MMC/SD mode is tried.
• If MMC/SD boot fails, then MMC/SD boot is tried again.
• If UART boot fails, then UART boot is tried again.
• If USB boot fails, then USB boot is tried again.
• If SPI boot fails, then SPI boot is tried again.
• If EMAC boot fails, then EMAC boot is tried again.
• If HPI boot fails, then HPI boot is tried again.
• RBL shall update boot status (PASS/FAIL) in MISC register bits 8 and 9 in System control module.
• ARM ROM Boot - NAND Mode
– No support for a full firmware boot. Instead, copies a second stage user boot loader (UBL) from
NAND flash to ARM internal RAM (AIM) and transfers control to the user-defined UBL.
– Support for NAND with page sizes up to 4096 bytes.
– Support for magic number error detection and retry (up to 24 times) when loading UBL
– Support for up to 30KB UBL (32KB IRAM - ~2KB for RBL stack)
– Optional, user-selectable, support for use of DMA and I-cache during RBL execution (i.e.,while
loading UBL)
– Supports booting from 8-bit NAND devices (16-bit NAND devices are not supported)
– Uses/Requires 4-bit HW ECC (NAND devices with ECC requirements ≤ 4 bits per 512 bytes are
supported)
– Supports NAND flash that requires chip select to stay low during the tR read time

ARM ROM Boot - MMC/SD Mode
– No support for a full firmware boot. Instead, copies a second stage User Boot Loader (UBL) from
MMC/SD to ARM Internal RAM (AIM) and transfers control to the user software.
– Support for MMC/SD Native protocol (MMC/SD SPI protocol is not supported)
– Support for descriptor error detection and retry (up to 24 times) when loading UBL
– Support for up to 30KB UBL (32KB - ~2KB for RBL stack)
– SDHC boot supported by RBL
ARM ROM Boot - UART mode
– If the state of BTSEL[2:0] pins at reset is 011, then the UART boot mode executes. This mode
enables a small program, referred to here as a user boot loader (UBL), to be downloaded to the
on-chip ARM internal RAM via the on-chip serial UART and executed. A host program, (referred to
as serial host utility program), manages the interaction with RBL and provides a means for operator
feedback and input. The UART boot mode execution assumes the following UART settings: 24
MHz reference clock, Time-Out 500 ms, one-shot Serial RS-232 port 115.2 Kbps, 8-bit, no parity,
one stop bit Command, data, and checksum format Everything sent from the host to the device
UART RBL must be in ASCII format
– No support for a full firmware boot. Instead, loads a second stage user boot loader (UBL) via UART
to ARM internal RAM (AIM) and transfers control to the user software.
– Support for up to 30KB UBL (32KB - ~2KB for RBL stack)
ARM ROM Boot – USB Mode
– No support for a full firmware boot. Instead, loads a second stage User Boot Loader (UBL) via USB
to ARM Internal RAM (AIM) and transfers control to the users software.
ARM ROM Boot – SPI Mode
– The device will copy UBL to ARM Internal RAM (AIM) via SPI interface from a SPI peripheral like
SPI EEPROM. RBL will then transfer control to the UBL.
ARM ROM Boot – EMAC Mode
– The device will send a boot request packet and the host/server will respond with the boot packets.
RBL will wait for all boot packets to arrive and then transfer control to the UBL which is received via
boot packets. In EMAC boot mode an I2C EEPROM or SPI EEPROM is necessary for
programming EMAC descriptor (including EMAC address for the device)
Note: If a magic number is not found in the EEPROM, then the EMAC boot mode will use a default
MAC address. In this case, there will be no magic number support.
ARM ROM Boot – HPI Mode
– The Host will copy UBL to ARM Internal RAM (AIM) via HPI interface and notify the ROM
bootloader after copy is finished. RBL will then transfer control to the UBL.
The general boot sequence is shown in Figure 3-1. For more information, refer to the TMS320DM36x
DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).

Device Clocking
Overview
The device requires one primary reference clock. The reference clock frequency may be generated either
by crystal input or by external oscillator. The reference clock is the clock at the pins named MXI1/MXO1,
and which drives two separate PLL controllers (PLLC1 and PLLC2). PLLC1 generates the clocks required
by the ARM, EDMA, VPSS and the rest of the peripherals. PLL2 generates the clock required by the DDR
PHY interface and is also capable of providing clocks to the ARM, USB, Video, or Voice Codec modules
as well as a flexible clocking option. Figure 3-2 represents the clocking architecture for the ARM
subsystem. For more information on device clocking and the system PLL controller please see the
TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).

Like the DM365, the DM368 uses two PLLs to generate the two fundamental clocks used on the device.
These two clocks feed two divider blocks which generate all of the functional clocks used by the
peripherals and cores in the DM368. The ARM926 and DDR peripheral in the DM368 are limited to a
maximum clock frequency of 432 MHz and 340 MHz respectively. There are some peripheral clocks on
the DM368 which are required to operate at a specific frequency by functional specification or convention.
These frequencies are detailed in Table 3-5.

While it is possible to generate both a 432 MHz and 340 MHz clock with the two PLLs, these two
frequencies cannot be divided down to generate all required frequencies from Table 3-5. Several different
frequency solutions are required to cover all of these requirements. The different solutions for different
input crystal frequencies are listed in the tables below.
The following tables show examples of the PLL combinations that can be supported with DM368. Please
see the TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5) for
additional details on special peripherals clocking considerations and for additional PLL controller
configuration details.
There are several important points to note from these tables.
• A 432 MHz functional clock will result in DM368 voice codec sampling frequency of 16.07KHz. The
difference of 0.4375% versus 16KHz specification should be acceptable for the majority of audio
applications. If the DM368 voice codec is required to operate at precisely 16 kHz then the functional
clock can be reduced to achieve precisely that sample frequency but the ARM926 and HDVICP will
have to run at a reduced rate resulting in lower video performance.
• If a 24 MHz input crystal is used it is not possible to generate a 74.25 MHz HD video output clock.
• If a 19.2 MHz input crystal is used it is not possible to generate a valid 74.25 MHz HD output clock.

For maximum H.264 encode performance the ARM must run at 432 MHz and the DDR at 340 MHz. Any
speed decrease to either of these will reduce encode performance. This means that if the ARM speed
must be reduced to enable another function it will impact the encode performance.
If USB is required then a 36 MHz, 24 MHz or 19.2 MHz input crystal is preferred as those can support
USB at full ARM rate.
If a video output is needed then a 36 MHz, 27 MHz or 24 MHz input crystal should be used. For HD video
output it may be preferred to use the EXTCLK input to inject an external 74.25 MHz clock and at the same
time operate the ARM at 432 MHz.
3.3.7
Peripheral Clocking Considerations
The device supports several peripherals with special clocking considerations (VPBE, USB, Key Scan,
ADC, Voice Codec, MJCP, HDVICP, AUXCLK, DDR2 EMIF). For more detail on these special
considerations, see the Peripheral Clocking Considerations section of theTMS320DM36x DMSoC ARM
Subsystem Reference Guide (literature number SPRUFG5).
3.4
Power and Sleep Controller (PSC)
In the device system, the Power and Sleep Controller (PSC) is responsible for managing transitions of
system power on/off, clock on/off, and reset. A block diagram of the PSC is shown in Figure 3-5. Many of
the operations of the PSC are transparent to software, such as power-on-reset operations. However, the
PSC provides you with an interface to control several important clock and reset operations.
The PSC includes the following features:
• Manages chip power-on/off, clock on/off, and resets

3.5
Pin Multiplexing
The device makes extensive use of pin multiplexing to accommodate the large number of peripheral
functions in the smallest possible package. In order to accomplish this, pin multiplexing is controlled using
a combination of hardware configuration (at device reset) and software control. No attempt is made by the
hardware to ensure that the proper pin muxing has been selected for the peripherals or interface mode
being used, thus proper pin muxing configuration is the responsibility of the board and software designers.
An overview of the pin multiplexing is shown in Table 3-10.
All pin multiplexing options are configurable by software via pin mux registers that reside in the System
Control Module. The PinMux0 Register controls the Video In muxing, PinMux1 register controls Video Out
signals, PinMux2 register controls AEMIF signals, PinMux3 registers control the multiplexing of the GIO
signals, the PinMux4 register controls the SPI and MMC/SD0 signals. See the TMS320DM36x DMSoC
ARM Subsystem Reference Guide (literature number SPRUFG5) for complete descriptions of the pin mux
registers.
The device configuration pins are multiplexed with AEMIF pins. Note that the AECFG[2:0] inputs only
select the default AEMIF address pin muxing. The number of active address pins may be increased or
reduced at any time by modifying the appropriate bits in the PinMux2 control register. After the device
configuration pins are sampled at reset, they automatically change to function as AEMIF pins. For more
details on AEMIF default configuration, see Section 3.7.5.

Device Reset
There are five types of reset. The types of reset differ by how they are initiated and/or by their effect on
the chip. Each type is briefly described in Table 3-11 and further described in the TMS320DM36x DMSoC
ARM Subsystem Reference Guide (literature number SPRUFG5).
Table 3-11. Reset Types
Type

3.7
Default Device Configurations
After POR, warm reset, and max reset, the chip is in its default configuration. This section highlights the
default configurations associated with PLLs, clocks, ARM boot mode, and AEMIF.
Note: Default configuration is the configuration immediately after POR, warm reset, and max reset and
just before the boot process begins. The boot ROM updates the configuration. See Section 3.2 for more
information on the boot process.
3.7.1
Device Configuration Pins
The device configuration pins are described in Table 3-12. The device configuration pins are latched at
reset and allow you to configure all of the following options at reset:
• ARM Boot Mode
• Asynchronous EMIF pin configuration
These pins are described further in the following sections.
Note: The device configuration pins are multiplexed with AEMIF pins. After the device configuration pins
are sampled at reset, they automatically change to function as AEMIF pins. Pin multiplexing is described
in Section 3.5.

PLL Configuration
After POR, warm reset, and max reset, the PLLs and clocks are set to their default configurations. The
PLLs are in bypass mode and disabled by default. This means that the input reference clock at MXI1
(typically 24 MHz) drives the chip after reset. For more information on device clocking, see Section 3.3 .
The default state of the PLLs is reflected in the default state of the register bits in the PLLC registers.
Refer to the TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).
3.7.3
Power Domain and Module State Configuration
Only a subset of modules are enabled after reset by default. Table 3-13 shows which modules are
enabled after reset. Table 3-13 shows that the following modules are enabled depending on the sampled
state of the device configuration pins. For example, if UART boot mode is BTSEL[2:0] = 011, then the
default state of the UART module is enabled. For more information on module configuration, refer to the
TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).

ARM Boot Mode Configuration
The ARM can boot from either Asynchronous EMIF (OneNand/NOR) or from ARM ROM, as determined
by the setting of the device configuration pins BTSEL[2:0]. The boot selection pins (BTSEL[2:0]) determine
the ARM boot process. After reset (POR, warm reset, or max reset), ARM program execution begins in
ARM ROM at 0x0000: 8000, except when BTSEL[2:0] = 001, indicating AEMIF (OneNand/NOR) flash
boot.
Boot modes are further described in Section 3.2.

3.7.5
AEMIF Configuration
3.7.5.1
AEMIF Pin Configuration
The input pins AECFG[2:0] determine the AEMIF configuration immediately after reset. Pins that are not
assigned to another peripheral and not enabled as address signals become GPIOs. These may be used
as ALE and CLE signals for NAND Flash control if booting from internal ROM. If booting from NOR Flash
then the appropriate number of address output must be enabled by the AECFG[2:0] inputs at reset. The
enabled address signals are always contiguous from EM_BA[1] upwards; bits cannot be skipped. EM_A[0]
does not represent the lowest AEMIF address bit. The device has 23 address lines and 2 chip selects with
an 8-bit or 16-bit option. The device supports only 8-bit and 16-bit data widths for the AEMIF.
•
•
16-bit mode: EM_BA[1] represents the LS address bit (the half-word address) and EM_BA[0]
represents address bit (A[14]). The maximum number of address lines pins in 16-bit mode are 23,
which include EM_BA[1] + EM_A[0:13] +EM_BA[0] (as pin A[14] via PINMUX2 register) + EM_A[15:20]
+EM_A[21] (via PINMUX4 register)
Note: Pins EM_A[15:21] are available by programming the PinMux4 register in software after boot, but
must be pulled down externally so that valid voltage levels are provided on the full set of address pins
during boot time. EM_A[15:21] come out of reset as GPIO pins per the PinMux4 register.
8-bit mode: EM_BA[1:0] represent the 2 LS address bits. Additional selections are available by
programming the PinMux2 register in software after boot. The maximum number of address lines in
8-bit mode are 23, which include EM_BA[0:1] + EM_A[0:13] + A[14] (via PINMUX4 register) +
EM_A[15:20].
Note: Pins EM_A[15:20] are available by programming the PinMux4 register in software after boot, but
must be pulled down externally so that valid voltage levels are provided on the full set of address pins
during boot time. EM_A[15:20] come out of reset as GPIO pins per the PinMux4 register.
For additional details about the PinMux2 and PinMux4 registers, see the TMS320DM36x DMSoC ARM
Subsystem Reference Guide (literature number SPRUFG5).
The device's pin-mux control logic allows all of the Asynchronous EMIF address pins to be used as
GPIOs. If devices (such as NAND Flash) attached to the AEMIF require less than the 16 address pins
provided, then the unused upper-order addresses may be configured as GPIOs. These pins must be
configured at reset so that pins being driven by the AEMIF with addresses will not cause bus contention
with pins being driven by the system as general purpose inputs.
The AECFG[2:0] value does not affect the operation of the AEMIF module itself, only which of its address
bits are seen on the device pins (resulting in the natural ramifications if devices don’t receive all address
signals or if contention with general purpose inputs occurs). As shown in Table 3-14, the number of
address bits enabled on the AEMIF is selectable from 0 to 16 at boot time, see notes above for additional
support of up-to 23 address lines.

AEMIF Timing Configuration
When AEMIF is enabled, the wait state registers are reset to the slowest possible configuration, which is
88 cycles per access (16 cycles of setup, 64 cycles of strobe, and 8 cycles of hold). Thus, with a 24 MHz
clock at MXI/MXO, the AEMIF is configured to run at (12 MHz/ 88) which equals approximately 136.36
kHz.
3.7.6
Oscillator Frequency Configuration
The oscillator input pins, MXI1, MXO, are designed to operate in two frequency ranges depending on the
GIO81(OSCCFG) pin sampled at reset, which should be set according to the required input frequency of
operation. See Table 3-15 for details.

The frequency selection pin cannot be changed dynamically while the oscillator is running. They should
only be set once before oscillator startup.
The GIO81(OSCCFG) state is latched during reset, and it specifies the oscillation frequency mode as
shown in Table 3-15.

3.8.1
Debugging Considerations
Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the DMSoC device always be at a valid logic level
and not floating. This may be achieved via pullup/pulldown resistors. The DMSoC features internal pullup
(IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for
external pullup/pulldown resistors.
An external pullup/pulldown resistor needs to be used in the following situations:
• Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external
pullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desired
value/state.
• Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external
pullup/pulldown resistor to pull the signal to the opposite rail.
For the boot and configuration pins, if they are both routed out and 3-stated (not driven), it is strongly
recommended that an external pullup/pulldown resistor be implemented. Although, internal
pullup/pulldown resistors exist on these pins and they may match the desired configuration value,
providing external connectivity can help ensure that valid logic levels are latched on these device boot and
configuration pins. In addition, applying external pullup/pulldown resistors on the boot and configuration
pins adds convenience to the user in debugging and flexibility in switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
• Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure
to include the leakage currents of all the devices connected to the net, as well as any internal pullup or
pulldown resistors.
• Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of
all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all
inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of
the limiting device; which, by definition, have margin to the VIL and VIH levels.
• Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the net
will reach the target pulled value when maximum current from all devices on the net is flowing through
the resistor. The current to be considered includes leakage current plus, any other internal and
external pullup/pulldown resistors on the net.
• For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance
value of the external resistor. Verify that the resistance is small enough that the weakest output buffer
can drive the net to the opposite logic level (including margin).
• Remember to include tolerances when selecting the resistor value.
• For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems, a 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria.
Users should confirm this resistor value is correct for their specific application.
For most systems, a 20-kΩ resistor can be used to compliment the IPU/IPD on the boot and configuration
pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific
application.
For more detailed information on input current (II), and the low-/high-level input voltages (VIL and VIH) for
the device, see Section 5.2, Recommended Operating Conditions.
For the internal pullup/pulldown resistors for all device pins, see the peripheral/system-specific terminal
functions table.

4 System Interconnect
The device uses a 64-bit crossbar architecture to control access between device processors, subsystems
and peripherals. There are eleven transfer masters (TCs have separate read and write connections)
connected to the crossbar; ARM, the Video Processing Subsystem (VPSS), the master peripherals (USB,
EMAC, HPI), and four EDMA transfer controllers. These can be connected to seven separate slave ports;
ARM, the DDR EMIF, CFG bus peripherals, MJCP, and HDVICP. Not all masters may connect to all
slaves. Connection paths are indicated by √ at intersection points shown in Table 4-1.

Device Pin
(see note)
The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its
transmission line effects must be taken into account. A model of the tester pin electronics is shown in Figure 6-1. A
transmission line with a delay of 2 ns or longer can be used to produce the desired transmission line effect. The
transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns or
longer) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the
device pin and the input signals are driven between 0V and the appropriate I/O supply for the signal.
Figure 6-1. Test Load Circuit for AC Timing Measurements
The load capacitance value stated is only for characterization and measurement of AC timing signals. This
load capacitance value does not indicate the maximum load the device is capable of driving.
6.1.1
Signal Transition Levels
All input and output timing parameters are referenced to Vref for both "0" and "1" logic levels. For 3.3 V I/O,
Vref = 1.65 V. For 1.8 V I/O, Vref = 0.9 V.
Vref
Figure 6-2. Input and Output Voltage Reference Levels for AC Timing Measurements
All rise and fall transition timing parameters are referenced to VIL MAX and VIH MIN for input clocks,
VOLMAX and VOH MIN for output clocks.
Vref = VIH MIN (or VOH MIN)
Vref = VIL MAX (or VOL MAX)

6.1.2
Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer
information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS
models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing
Analysis Application Report (literature number SPRA839). If needed, external logic hardware such as
buffers may be used to compensate any timing differences.

Power-Supply Sequencing
In order to ensure device reliability, the device requires the following power supply power-on and
power-off sequences. See Section 5.2, Recommended Operating Conditions, for a description of the
power supplies.
• The following power sequences are recommended to prevent damage to the device.
• The PRTCSS core must always be powered-on and powered-off regardless of whether the PRTCSS
feature is used.
• If the PRTCSS sequencer is to be used in any PRTCSS modes, please refer to the TMS320DM36x
PRTCSS User's Guide (literature number SPRUFJ0) for more details on the differences to the power
sequence.
6.4.1
Simple Power-On and Power-Off Method
The following steps must be followed in sequential order for the simple power-on method:
1. Power on the PRTCSS/ Main core (1.35-V).
2. Power on the PRTCSS/Main I/O (1.8-V).
3. Power on the Main/Analog I/O (3.3-V).
Note for simple power-on: RESET must be low until all supplies are ramped up.
The following steps should be followed for the simple power-off method:
1. Power off the Main/Analog I/O (3.3-V).
2. Power off the PRTCSS/Main I/O (1.8-V).
3. Power off the PRTCSS/Main core (1.35-V).
Notes for simple power-off:
– If RESET is low, steps 2 and 3 may be performed simultaneously.
– If RESET is not low, these steps must be followed sequentially.
6.4.2
Restricted Power-On and Power-Off Method
The following steps should be followed for the restricted power-on method:
1. Power on the PRTCSS/ Main core (1.35-V).
2. Power on the PRTCSS/Main I/O (1.8-V).
3. Power on the Main/Analog I/O (3.3-V).
Notes for restricted power-on:

– RESET must be low until all supplies are ramped up.
– Steps 1, 2, and 3 may be performed simultaneously if the Main core finishes ramping up before the
I/Os and the maximum delta voltage difference between the 1.8-V and 3.3-V I/Os is 2.0-V until the
1.8-V I/O reaches the full voltage.
The following steps should be followed for the restricted power-off method:
1. Power off Main/Analog I/O (3.3-V).
2. Power off PRTCSS/Main I/O (1.8-V).
3. Power off PRTCSS/Main core (1.35-V).
Notes for restricted power-off:
– The 3.3-/1.8-V I/Os may be powered off simultaneously if the maximum delta voltage difference
between them is 2.0V until the 1.8-V I/O is completely powered off, and the PRTCSS/Main core
must be powered down last.
When booting the DM368 from OneNAND, you must ensure that the OneNAND device is ready with valid
program instructions before the DM368 attempts to read program instructions from it. In particular, before
you release the device's reset, you must allow time for OneNAND device power to stabilize and for the
OneNAND device to complete its internal copy routine. During the internal copy routine, the OneNAND
device copies boot code from its internal non-volatile memory to its internal boot memory section. Board
designers typically achieve this requirement by design of the system power and reset supervisor circuit.
Refer to your OneNAND device datasheet for OneNAND power ramp and stabilization times and for
OneNAND boot copy times.
6.4.3
Power-Supply Design Considerations
Core and I/O supply voltage regulators should be located close to the device to minimize inductance and
resistance in the power delivery path. Additionally, when designing for high-performance applications
utilizing the device, the PC board should include separate power planes for core, I/O, and ground, all
bypassed with high-quality low-ESL/ESR capacitors.
6.4.4
Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to the device. These caps need to be close to the power pins, no more than 1.25 cm
maximum distance to be effective. Physically smaller caps, such as 0402, are better because of their
lower parasitic inductance. Proper capacitance values are also important. Small bypass caps (near 560
pF) should be closest to the power pins. Medium bypass caps (220 nF or as large as can be obtained in a
small package) should be next closest. TI recommends no less than 8 small and 8 medium caps per
supply be placed immediately next to the BGA vias, using the "interior" BGA space and at least the
corners of the "exterior".
Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the order
of 100 uF) should be furthest away, but still as close as possible. Large caps for each supply should be
placed outside of the BGA footprint.
Any cap selection needs to be evaluated from a yield/manufacturing point-of-view. As with the selection of
any component, verification of capacitor availability over the product’s production lifetime should be
considered. See also Section 6.6.1 for additional recommendations on power supplies for the
oscillator/PLL supplies.

Oscillators and Clocks
The device has one oscillator input/output pair (MXI1/MXO1) usable with external crystals or ceramic
resonators to provide clock inputs. The optimal frequencies for the crystals are 19.2 MHz, 24 MHz, 27
MHz, and 36 MHz. Optionally, the oscillator inputs are configurable for use with external clock oscillators.
If external clock oscillators are used, to minimize the clock jitter, a single clean power supply should power
both the device and the external oscillator circuit and the minimum CLKIN rise and fall times must be
observed. The electrical requirements and characteristics are described in this section.
The timing parameters for CLKOUT[3:1] are also described in this section. The device has three output
clock pins (CLKOUT[3:1]). See Section 3.3 for more information on CLKOUT[3:1].
Note: Please ensure that the appropriate oscillator input pin (GIO81/OSCCFG) frequency range setting is
set correctly. For more details on this pin setting, see Section 3.7.6.
6.6.1
MXI1 Oscillator
The MXI1 (typically 24 MHz, can also be 19.2 MHz, 27 MHz, or 36 MHz) oscillator provides the primary
reference clock for the device. The on-chip oscillator requires an external crystal connected across the
MXI1 and MXO1 pins, along with two load capacitors, as shown in Figure 6-5. The external crystal load
capacitors must be connected only to the oscillator ground pin (VSS_MX1). Do not connect to board ground
(VSS). Also, the PLL power pin (VDDA_PLL1) should be connected to the power supply through a ferrite
bead, L1 in the example circuit shown in Figure 6-5.
Note: If an external oscillator is to be used, the external oscillator clock signal should be connected to the
MXI1 pin with a 1.8V amplitude. The MXO1 should be left unconnected and the VSS_MX1 signal should
be connected to board ground (Vss).

General-Purpose Input/Output (GPIO)
The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.
When configured as an output, a write to an internal register can control the state driven on the output pin.
When configured as an input, the state of the input is detectable by reading the state of an internal
register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different
interrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.
The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GPIO [0:15]). There
are a total of 7 GPIO banks in the device, because the device has 104 GPIOs. For additional details on
GPIO pins voltage level and the associated power supply please see Table 6-11.

The GPIO peripheral supports the following:
• Up to 104 GPIO pins, GPIO[103:0]
• Up to 7 GPIO pins dedicated to the PRTC Subsystem. These pins are labeled as PWRCTRIO[6:0].
Only PWRCTRIO[2:0] are connected to the GPIO module, labeled as GPIO[106:104]. For the PRTCSS
module the PWRCTRIO[6:0] pins support input and output functionality but for the GPIO module the
GPIO[106:104] pins support input functionality only. For more details please refer to Section 6.7.
• Interrupts:
– Up to 15 unique GPIO[15:0] interrupts from Bank 0.
– Up to 3 unique GPIO[106:104] interrupts from Bank 6, dedicated to the PRTC Subsystem. For
more details please refer to Section 6.7.
– Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIO
signal
• DMA events:
– Up to 15 unique GPIO DMA events from Bank 0
• Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO
signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section
protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to
anther process during GPIO programming).
• Separate Input/Output registers
• Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals can
be toggled by direct write to the output register(s).
• Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status, allows wired logic be implemented.
For more detailed information on GPIOs, see the Documentation Support section for the General-Purpose
Input/Output (GPIO) Reference Guide.

The pulse width given is sufficient to generate an interrupt or an EDMA event. However, if a user wants the device to recognize the
GPIO changes through software polling of the GPIO register, the GPIO duration must be extended to allow the device enough time to
access the GPIO register through the internal bus.

– I2C
– PWM
– RTO
– GPIO
– Timer/WDT
– UART
– MMC/SD
The EDMA Controller consists of two major blocks: the Transfer Controller (TC) and the Channel
Controller (CC). The CC is a highly flexible Channel Controller that serves as the user interface and event
interface for the EDMA system. The CC supports 64-event channels and 8 QDMA channels. The CC
consists of a scalable Parameter RAM (PaRAM) that supports flexible ping-pong, circular buffering,
channel-chaining, auto-reloading, and memory protection.
The EDMA Channel Controller has the following features:
• Fully orthogonal transfer description
– Three transfer dimensions
– A-synchronized transfers: one dimension serviced per event
– AB- synchronized transfers: two dimensions serviced per event
– Independent indexes on source and destination
– Chaining feature allows 3-D transfer based on single event
• Flexible transfer definition
– Increment and constant addressing modes
– Linking mechanism allows automatic PaRAM set update
– Chaining allows multiple transfers to execute with one event
• Interrupt generation for:
– DMA completion
– Error conditions
• Debug visibility
– Queue watermarking/threshold
– Error and status recording to facilitate debug
• 64 DMA channels
– Event synchronization
– Manual synchronization (CPU(s) write to event set register)
– Chain synchronization (completion of one transfer chains to next)
• 8 QDMA channels
– QDMA channels are triggered automatically upon writing to a PaRAM set entry
– Support for programmable QDMA channel to PaRAM mapping
• 256 PaRAM sets
– Each PaRAM set can be used for a DMA channel, QDMA channel, or link set (remaining)
• Four transfer controllers/event queues. The system-level priority of these queues is user programmable
• 16 event entries per event queue
• External events (for example, McBSP TX Evt and RX Evt)
The EDMA Transfer Controller has the following features:
•

Support for increment and constant addressing modes
Interrupt and error support
Parameter RAM: Each EDMA is specified by an eight word (32-byte) parameter table contained in
Parameter RAM (PaRAM) within the CC. The device provides 256 PaRAM entries, one for each of the 64
DMA channels and for 8 QDMA / Linked DMA entries.
DMA Channels: Can be triggered by: " External events (for example, McBSP TX Evt and RX Evt), "
Software writing a '1' to the given bit location, or channel, of the Event Set register, or, " Chaining to other
DMAs.
QDMA: The Quick DMA (QDMA) function is contained within the CC. The device implements 8 QDMA
channels. Each QDMA channel has a selectable PaRAM entry used to specify the transfer. A QDMA
transfer is submitted immediately upon writing of the "trigger" parameter (as opposed to the occurrence of
an event as with EDMA). The QDMA parameter RAM may be written by any Config bus master through
the Config Bus and by DMAs through the Config Bus bridge.
QDMA Channels: Triggered by a configuration bus write to a designated 'QDMA trigger word'. QDMAs
allow a minimum number of linear writes (optimized for GEM IDMA feature) to be issued to the CC to
force a series of transfers to take place.
6.9.1
EDMA Channel Synchronization Events
The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 6-16 lists the source of EDMA synchronization events associated with each of the programmable
EDMA channels. For the device, the association of an event to a channel is fixed; each of the EDMA
channels has one specific event associated with it. These specific events are captured in the EDMA event
registers (ER, ERH) even if the events are disabled by the EDMA event enable registers (EER, EERH).
For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, etc., see the Document Support section for the Enhanced Direct
Memory Access (EDMA) Controller Reference Guide.

In addition to the events shown in this table, each of the 64 channels can also be synchronized with the transfer completion or
intermediate transfer completion events. For more detailed information on EDMA event-transfer chaining, see the Document Support
section for the Enhanced Direct Memory Access (EDMA) Controller Reference Guide.
The total number of EDMA events exceeds 64, which is the maximum value of the EDMA module. Therefore, several events are
multiplexed and you must use the register EDMA_EVTMUX in the System Control Module to select the event source for multiplexed
events. Refer to the TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5) for more information on
the System Control Module register EDMA_EVTMUX.

6.10.3.1 DDR2/mDDR Interface
This section provides the timing specification for the DDR2/mDDR interface as a PCB design and
manufacturing specification. The design rules constrain PCB trace length, PCB trace skew, signal
integrity, cross-talk, and signal timing. These rules, when followed, result in a reliable DDR2/mDDR
memory system without the need for a complex timing closure process. For more information regarding
guidelines for using this DDR2 specification, Understanding TI's PCB Routing Rule-Based DDR2 Timing
Specification (SPRAAV0).

dimensions for Figure 6-21 are defined in Table 6-27. The placement does not restrict the side of the PCB
that the devices are mounted on. The ultimate purpose of the placement is to limit the maximum trace
lengths and allow for proper routing space. For single-memory DDR2/mDDR systems, the second
DDR2/mDDR device is omitted from the placement.

6.10.3.1.7 High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critical for proper DDR2/mDDR interface operation. It is
particularly important to minimize the parasitic series inductance of the HS bypass cap,
DMSoC/DDR2/mDDR power, and DMSoC/DDR2/mDDR ground connections. Table 6-29 contains the
specification for the HS bypass capacitors as well as for the power connections on the PCB.
6.10.3.1.8 Net Classes
Table 6-30 lists the clock net classes for the DDR2/mDDR interface. Table 6-31 lists the signal net
classes, and associated clock net classes, for the signals in the DDR2/mDDR interface. These net classes
are used for the termination and routing rules that follow.

6.10.3.1.10 VREF Routing
VREF is used as a reference by the input buffers of the DDR2/mDDR memories as well as the device.
VREF is intended to be the DDR2/mDDR power supply voltage and should be created using a resistive
divider as shown in Figure 6-19. Other methods of creating VREF are not recommended. Figure 6-23
shows the layout guidelines for VREF.

6.12 Video Processing Subsystem (VPSS) Overview
The device contains a Video Processing Subsystem (VPSS) that provides an input interface (Video
Processing Front End or VPFE) for external imaging peripherals such as image sensors, video decoders,
etc.; and an output interface (Video Processing Back End or VPBE) for display devices, such as analog
SDTV/HDTV displays, digital LCD panels, etc.
In addition to these peripherals, there is a set of common buffer memory and DMA control to ensure
efficient use of the DDR2/mDDR burst bandwidth. The shared buffer logic/memory is a unique block that
is tailored for seamlessly integrating the VPSS into an image/video processing system. It acts as the
primary source or sink to all the VPFE and VPBE modules that are either requesting or transferring data
from/to DDR2/mDDR . In order to efficiently utilize the external DDR2/mDDR bandwidth, the shared buffer
logic/memory interfaces with the DMA system via a high bandwidth bus (64-bit wide). The shared buffer
logic/memory also interfaces with all the VPFE and VPBE modules via a 128-bit wide bus. The shared
buffer logic/memory (divided into the read & write buffers and arbitration logic) is capable of performing the
following functions. It is imperative that the VPSS utilize DDR2/mDDR bandwidth efficiently due to both its
large bandwidth requirements and the real-time requirements of the VPSS modules. Because it is possible
to configure the VPSS modules in such a way that DDR2/mDDR bandwidth is exceeded, a set of user
accessible registers is provided to monitor overflows or failures in data transfers.
NOTE
DM368 does not support the Hardware 3A statistics collection module (H3A).
6.12.1 Video Processing Front-End (VPFE)
The VPFE or Video Processing Front-End block is comprised of the Image Sensor Interface (ISIF), Image
Pipe (IPIPE), Image Pipe Interface (IPIPEIF), and a Hardware Face Detect Engine. These modules are
described in the sections that follow.
The VPFE sub-module register memory mapping is shown in Table 6-39.

6.12.1.1 Image Sensor Interface (ISIF)
The ISIF is responsible for accepting raw (unprocessed) image/video data from a sensor (CMOS or CCD).
In addition, the ISIF can accept YUV video data in numerous formats, typically from so-called video
decoder devices. In case of raw inputs, the ISIF output requires additional image processing to transform
the raw input image to the final processed image. This processing can be done either on-the-fly in IPIPE
or in software on the ARM and MPEG/JPEG and HD Video Image coprocessor subsystems. The ISIF is
programmed via control and parameter registers. The following features are supported by the ISIF
module.
• Support for conventional Bayer pattern, pixel summation mode, and RGB stripe sensor formats.
• Support for the various pixel summation mode formats is provided via a data reformatter of ISIF, which
transforms any specific sensor formats to the Bayer format. The maximum line width supported by the
reformatter is 4736 pixels.
• Image processing steps applicable to RGB stripe sensors are limited to color-dependent gain control
and black level offset control."
• Generates HD/VD timing signals and field ID to an external timing generator, or can synchronize to the
external timing generator.
• Support for progressive and interlaced sensors (hardware support for up to 2 fields and firmware
support for higher number of fields, typically 3-, 4-, and 5-field sensors.
• Support for up to 32K pixels (image size) in both the horizontal and vertical direction.
• Support for up to 120 MHz sensor clock.
• Support for ITU-R BT.656/1120 standard format.
• Support for YCbCr 422 format, either 8- or 16-bit with discrete HSYNC and VSYNC signals.
• Support for up to 16-bit input.
• Support for color space conversion.
• Digital clamp with Horizontal/Vertical offset drift compensation.
• Vertical Line defect correction based on a lookup table that contains defect position.
• Support for color-dependent gain control and black level offset control.
• Ability to control output to the DDR2/mDDR via an external write enable signal.
• Support for down sampling via programmable culling patterns.
• Support for 12-bit to 8-bit DPCM compression.
• Support for 10-bit to 8-bit A-law compression.
• Support for generating output to range 16-bits, 12-bits, and 8-bits wide (8-bits wide allows for 50%
saving in storage area).
• OTF DPC
• Noise Filter
• 2D edge enhancement

6.12.1.2 The Image Pipe Interface (IPIPEIF)
The IPIPEIF is data and sync signals interface module for ISIF and IPIPE. Data source of this module is
sensor parallel port, ISIF or SDRAM and the selected data is output to ISIF and IPIPE. This module also
outputs black frame subtraction (two-way) data which is generated by subtracting SDRAM data from
sensor parallel port or ISIF data and vice versa. Depending on the functions performed, it may also
readjust the HD, VD, and PCLK timing to the IPIPE and/or ISIF input.
The IPIPEIF module supports the following features:
• Up to 16-bit sensor data input
• Dark-frame subtract of raw image stored in SDRAM from image coming from sensor parallel port or
ISIF
• 8-10, 8-12 DPCM decompression of 10-8, 12-8 compressed data in SDRAM
• Inverse ALAW decompression of RAW data from SDRAM
• (1,2,1) average filtering before horizontal decimation
• Horizontal decimation (downsizing) of input lines to OSDWIN1 > OSDWIN0 > VIDWIN1 > VIDWIN0 >
background color
Support for attenuation of the YCbCr values for the REC601 standard.
The following restrictions exist in the OSD module.
• If the vertical resize filter is enabled for either of the video windows, the maximum horizontal window
dimension cannot be greater than 1024 currently. This is due to the limitation in the size of the line
memory.
• It is not possible to use both of the CLUT ROMs at the same time. However, a window can use RAM
while another uses ROM.

6.12.2.4 High-Definition (HD) DACs and Video Buffer Electrical Data/Timing
Three DACs and a video buffer are available on the device.
6.12.2.4.1 HD DACs-Only Option
In the HD DACs-only configuration, the internal video buffer is not used and an external video buffer is
attached to the DACs. Another solution is to use a Video Amplifier, such as the Texas Instruments'
THS7303 which provides a complete solution to the typical output circuit shown in Figure 6-39.

The USB2.0 peripheral supports the following features:
• USB 2.0 peripheral at speeds high speed (HS: 480 Mb/s) and full speed (FS: 12 Mb/s)
• USB 2.0 host at speeds HS, FS, and low speed (LS: 1.5 Mb/s)
• All transfer modes (control, bulk, interrupt, and isochronous)
• Four Transmit (TX) and four Receive (RX) endpoints in addition to endpoint 0
• FIFO RAM
– 4K bytes shared by all endpoints.
– Programmable FIFO size
• Includes a DMA sub-module that supports four TX and four RX channels of CPPI 3.0 DMAs
• RNDIS mode for accelerating RNDIS type protocols using short packet termination over USB
• USB OTG extensions, i.e. session request protocol (SRP) and host negotiation protocol (HNP)
The USB2.0 peripheral does not support the following features:
• On-chip charge pump
• High bandwidth ISO mode is not supported (triple buffering)
• RNDIS mode acceleration for USB sizes that are not multiples of 64 bytes
• Endpoint max USB packet sizes that do not conform to the USB 2.0 spec (for FS/LS: 8, 16, 32, 64,
and 1023 are defined; for HS: 64, 128, 512, and 1024 are defined)

Universal Asynchronous Receiver/Transmitter (UART)
The UART module performs serial-to-parallel conversion on data received from a peripheral device or
modem, and parallel-to-serial conversion on data received from the CPU. Each UART also includes a
programmable baud rate generator capable of dividing the module's reference clock by divisors from 1 to
65,535 to produce a 16 x clock driving the internal logic. The UART modules support the following
features:
• Frequency pre-scale values from 1 to 65,535 to generate appropriate baud rates
• 16-byte storage space for both the transmitter and receiver FIFOs
• Unique interrupts, one for each UART
• Unique EDMA events, both received and transmitted data for each UART
• 1, 4, 8, or 14 byte selectable receiver FIFO trigger level for autoflow control and DMA
• Programmable auto-rts and auto-cts for autoflow control (supported on UART1)
• Programmable serial data formats
– 5, 6, 7, or 8-bit characters
– Even, odd, or no parity bit generation and detection
– 1, 1.5, or 2 stop bit generation
• False start bit detection
• Line break generation and detection
• Internal diagnostic capabilities
– Loopback controls for communications link fault isolation
– Break, parity, overrun, and framing error simulation
• Modem control functions: CTS, RTS (supported on UART1)

Serial Port Interface (SPI)
The SPI module provides a programmable length shift register which allows serial communication with
other SPI devices through a 3 or 4 wire interface (Clock, Data In, Data Out, and Chip-select). The SPI
supports the following features:
• Master and Slave mode operation is supported on all SPI ports (master mode means that the device
provides the serial clock)
• 2 chip selects for interfacing to multiple slave SPI devices.
• 3 or 4 wire interface (Clock, Data In, Data Out, and Enable)
• Unique interrupt for each SPI port (except SPI4)
• Separate EDMA events for SPI Receive and Transmit for each SPI port (except SPI4)
• 16-bit shift register
• Receive buffer register
• Programmable character length (2 to 16 bits)
• Programmable SPI clock frequency range
• 8-bit clock prescaler
• Programmable clock phase (delay or no delay)
• Programmable clock polarity
Note: SPI4 slave mode does not support Chip-select input, only supports 3-wire interface.
The SPI modules do not support the following features:
• GPIO mode. GPIO functionality is supported by the GIO modules for those SPI pins that are
multiplexed with GPIO signals.

6.17 Multi-Channel Buffered Serial Port (McBSP)
The primary use for the Multi-Channel Buffered Serial Port (McBSP) is for audio interface purposes. The
primary audio modes that are supported by the McBSP are the AC97 and IIS modes. In addition to the
primary audio modes, the McBSP supports general serial port receive and transmit operation, but is not
intended to be used as a high-speed interface. The McBSP supports the following features:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• External shift clock generation or an internal programmable frequency shift clock
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
• Direct interface to AC97 compliant devices (the necessary multiphase frame synchronization capability
is provided)
• Direct interface to IIS compliant devices
• Direct interface to SPI protocol in master mode only
• A wide selection of data sizes, including 8, 12, 16, 20, 24, and 32 bits
• μ-Law and A-Law companding
• 8-bit data transfers with the option of LSB or MSB first
• Programmable polarity for both frame synchronization and data clocks
• Highly programmable internal clock and frame generation
• Direct interface to T1/E1 Framers
• Multi-channel transmit and receive of up to 128 channels
For more detailed information on the McBSP peripheral, see the Documentation Support section for the
Multi-Channel Buffered Serial Port (McBSP) Reference Guide.

CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also
inverted.
P = (1/SYSCLK4), where SYSCLK4 is an output clock of PLLC1 (see Section 3.3) .
Use whichever value is greater. Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock
source. The minimum CLKR/X cycle times are based on internal logic speed; the maximum usable speed may be lower due to EDMA
limitations and AC timing requirements.
This parameter applies to the maximum McBSP frequency. Operate serial clocks (CLKR/X) in the reasonable range of 40/60 duty cycle.

CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also
inverted.
Minimum delay times also represent minimum output hold times.
P = (1/SYSCLK4), where SYSCLK4 is an output clock of PLLC1 (see Section 3.3) .
Use whichever value is greater. Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock
source.

L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
L = (CLKGDV + 1)/2 * S if CLKGDV is odd
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit.
Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.

6.18 Timer
The device contains four software-programmable timers. Timer 0, Timer 1, Timer 3, and Timer 4
(general-purpose timers) can be programmed in 64-bit mode, dual 32-bit unchained mode, or dual 32-bit
chained mode. Timer 3 supports additional features over the other timers: external clock/event input,
period reload, output event tied to Real Time Out (RTO) module, external event capture, and timer counter
register read reset. Timer 2 is used only as a watchdog timer. Timer 2 is tied to device reset.
• 64-bit count-up counter
• Timer modes:
– 64-bit general-purpose timer mode (Timer 0, 1, 3, 4)
– Dual 32-bit general-purpose timer mode (Timer 0, 1, 3, 4)
– Watchdog timer mode (Timer 2)
• Two possible clock sources:
– Internal clock
– External clock/event input via timer input pins (Timer 3)
• Three possible operation modes:
– One-time operation (timer runs for one period then stops)
– Continuous operation (timer automatically resets after each period)
– Continuous operation with period reload (Timer 3)
• Generates interrupts to the ARM CPU
• Generates sync event to EDMA
• Generates output event to device reset (Timer 2)
• Generates output event to Real Timer Out (RTO) module (Timer 3)
• External event capture via timer input pins (Timer 3)

Pulse Width Modulator (PWM)
The pulse width modulator (PWM) feature is very common in embedded systems. It provides a way to
generate a pulse periodic waveform for motor control or can act as a digital-to-analog converter with some
external components. This PWM peripheral is basically a timer with a period counter and a first-phase
duration comparator, where bit width of the period and first-phase duration are both programmable. The
Pulse Width Modulator (PWM) modules support the following features:
• 32-bit period counter
• 32-bit first-phase duration counter
• 8-bit repeat count for one-shot operation. One-shot operation will produce N + 1 periods of the
waveform, where N is the repeat counter value.
• Configurable to operate in either one-shot or continuous mode
• Buffered period and first-phase duration registers
• One-shot operation triggerable by hardware events with programmable edge transitions. (low-to-high or
high-to-low).
• One-shot operation triggerable by the ISIF VSYNC output of the video processing subsystem (VPSS),
which allows any of the PWM instantiations to be used as a ISIF timer. This allows the device module
to support the functions provided by the ISIF timer feature (generating strobe and shutter signals).
• One-shot operation generates N+1 periods of waveform, N being the repeat count register value
• Configurable PWM output pin inactive state
• Interrupt and EDMA synchronization events

6.21 Ethernet Media Access Controller (EMAC)
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the device and the
network. The EMAC supports both 10Base-T (10 Mbits/second [Mbps]) and 100Base-TX (100 Mbps) in
either half- or full-duplex mode. The EMAC module also supports hardware flow control and quality of
service (QOS) support.
The frequencies supported for transmit and receive clocks are fixed by the IEEE 802.3 standard as:
• 2.5 MHz for 10Mbps
• 25 MHz for 100Mbps
The EMAC controls the flow of packet data from the device to the PHY. The MDIO module controls PHY
configuration and status monitoring.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the “Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) Access Method and Physical Layer” specifications. The IEEE
802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviation from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER.
Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will
intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame
will be detected as an error by the network
Both the EMAC and the MDIO modules interface to the device through a custom interface that allows
efficient data transmission and reception. This custom interface is referred to as the EMAC control
module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to
multiplex and control interrupts.
For more information on the TMS320DM36x DMSoC Ethernet Media Access Controller User's Guide
(literature number SPRUFI5).

Management Data Input/Output (MDIO)
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to
interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO
module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the
negotiation results, and configure required parameters in the EMAC module for correct operation. The
module is designed to allow almost transparent operation of the MDIO interface, with very little
maintenance from the core processor. Only one PHY may be connected at any given time.
For more detailed information on the MDIO peripheral, see the TMS320DM36x DMSoC Ethernet Media
Access Controller User's Guide (literature number SPRUFI5).

6.23 Host-Port Interface (HPI) Peripheral
Note: HPI is pin multiplexed with Asynchronous EMIF at the output pin. HPI is available only when boot
mode selected is HPI boot mode. In this configuration, the device will always act as a slave.
6.23.1 HPI Device-Specific Information
The device includes a user-configurable 16-bit Host-port interface (HPI16).
• Multiplexed (address/data) operation
• Configurable single full-word cycle and dual half-word cycle access modes
• Bursting available utilizing 8-word read and write FIFOs
• HPIA register supports auto-incrementing
• HPID register/FIFOs providing data-path between external host interface and system bus
• Multiple strobes and control signals to allow flexible host connection
• Software control of data prefetching to the HPID/FIFOs
• DMSoC-to-Host interrupt output signal controlled by HPIC accesses
• Host-to-DMSoC interrupt controlled by HPIC accesses
NOTE: The device HPI does not support the HAS feature. For proper HPI operation if the HAS pin is
routed out, the HAS pin must be pulled up via an external resistor.
The device HPICTL register (0x01C4 0024) is part of the System Module Registers. The HPICTL register
controls write access to the HPI peripheral control and address registers as well as determines the host
time-out value.
6.23.2 HPI Bus Master
The HPI peripheral includes a bus master interface that allows external device initiated transfers to access
the DM368 system bus. See the Master Peripheral Mem Map column in Table 2-3, the device Memory
Map.

6.27 IEEE 1149.1 JTAG
The JTAG (1) interface is used for BSDL testing and emulation of the device.
The device requires that both TRST and RESET be asserted upon power up to be properly initialized.
While RESET initializes the device, TRST initializes the device's emulation logic. Both resets are required
for proper operation.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for
the device to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG
port interface and device's emulation logic in the reset state.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or
exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by
TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted.
RESET must be released only in order for boundary-scan JTAG to read the variant field of IDCODE
correctly. Other boundary-scan instructions work correctly independent of current state of RESET.
For maximum reliability, the device includes an internal pulldown (PD) on the TRST pin to ensure that
TRST will always be asserted upon power up and the device's internal emulation logic will always be
properly initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG
controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the device after power up and externally
drive TRST high before attempting any emulation or boundary scan operations. Following the release of
RESET, the low-to-high transition of TRST must be "seen" to latch the state of EMU1 and EMU0. The
EMU[1:0] pins configure the device for either Boundary Scan mode or Emulation mode. For more detailed
information, see the terminal functions section of this data sheet.
6.27.1 JTAG Register Description(s)
Table 6-104 shows the DEVICE ID register (which includes the JTAG ID related information), its
corresponding acronym, and the device memory location. For more details on the DEVICE ID register bit
fields, see the TMS320DM36x DMSoC ARM Subsystem Reference Guide (literature number SPRUFG5).
