Description

Description
The TMS320C64x™ DSPs (including the TMS320DM641 and TMS320DM640 devices) are the
highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320DM641
(DM641) and TMS320DM640 (DM640) devices are based on the second-generation high-performance,
advanced VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™) developed by Texas
Instruments (TI), making these DSPs an excellent choice for digital media applications. The C64x™ is a
code-compatible member of the C6000™ DSP platform.
With performance of up to 4800 million instructions per second (MIPS) at a clock rate of 600 MHz, the DM641
device offers cost-effective solutions to high-performance DSP programming challenges.
With performance of up to 3200 million instructions per second (MIPS) at a clock rate of 400 MHz, the DM640
device offers cost-effective solutions to high-performance DSP programming challenges.
The DM641/DM640 DSP possesses the operational flexibility of high-speed controllers and the numerical
capability of array processors. The C64x™ DSP core processor has 64 general-purpose registers of 32-bit
word length and eight highly independent functional units—two multipliers for a 32-bit result and six arithmetic
logic units (ALUs)— with VelociTI.2™ extensions. The VelociTI.2™ extensions in the eight functional units
include new instructions to accelerate the performance in video and imaging applications and extend the
parallelism of the VelociTI™ architecture. The DM641 can produce four 16-bit multiply-accumulates (MACs)
per cycle for a total of 2400 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of
4800 MMACS. The DM640 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of
1600 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 3200 MMACS. The
DM641/DM640 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000™ DSP platform devices.
The DM641/DM640 uses a two-level cache-based architecture and has a powerful and diverse set of
peripherals. The Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache
(L1D) is a 128-Kbit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 1-Mbit memory
space that is shared between program and data space. L2 memory can be configured as mapped memory,
cache, or combinations of the two. The peripheral set includes: two configurable video ports (DM641); one
configurable video port (DM640); a 10/100 Mb/s Ethernet MAC (EMAC); a management data input/output
(MDIO) module; a VCXO interpolated control port (VIC); one 4-bit multichannel buffered audio serial port
(McASP0); an inter-integrated circuit (I2C) Bus module; two multichannel buffered serial ports (McBSPs);
three 32-bit general-purpose timers; a 16-bit host-port interface (HPI16) [DM641]; an 8-pin general-purpose
input/output port (GP0) with programmable interrupt/event generation modes; and a 32-bit glueless external
memory interface (EMIFA), which is capable of interfacing to synchronous and asynchronous memories and
peripherals.
The DM641 device has two single-channel 8-bit configurable video port peripherals (VP0 and VP1). The
DM640 device has one single-channel 8-bit configurable video port peripheral (VP0). These video port
peripherals provide a glueless interface to common video decoder and encoder devices. The DM641/DM640
video port peripherals support multiple resolutions and video standards (e. g., CCIR601 and ITU−BT.656).
These video port peripherals are configurable and can support either video capture and/or video display
modes.
For more details on the Video Port peripherals, see the TMS320C64x DSP Video Port/VCXO Interpolated
Control (VIC) Port Reference Guide (literature number SPRU629).
The McASP0 port supports one transmit and one receive clock zone, with four serial data pins which can be
individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin
from 2 to 32 time slots. The DM641/DM640 has sufficient bandwidth to support all 4 serial data pins
transmitting a 192-kHz stereo signal. Serial data in each zone may be transmitted and received on multiple
2
serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I S)
format.

Description
In addition, the McASP0 transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3,
CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user
data and channel status fields.
McASP0 also provides extensive error-checking and recovery features, such as the bad clock detection circuit
for each high-frequency master clock which verifies that the master clock is within a programmed frequency
range.
The VCXO interpolated control (VIC) port provides digital-to-analog conversion with resolution from 9-bits to
up to 16-bits. The output of the VIC is a single bit interpolated D/A output. For more details on the VIC port,
see the TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature
number SPRU629).
The ethernet media access controller (EMAC) provides an efficient interface between the DM641/DM640 DSP
core processor and the network. The DM641/DM640 EMAC support both 10Base-T and 100Base-TX, or 10
Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality of
service (QOS) support. The DM641/DM640 EMAC makes use of a custom interface to the DSP core that
allows efficient data transmission and reception. For more details on the EMAC, see the TMS320C6000 DSP
Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO) Module Reference
Guide (literature number SPRU628).
The management data input/output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system. Once a PHY candidate has been selected by the DSP, the MDIO
module transparently monitors its link state by reading the PHY status register. Link change events are stored
in the MDIO module and can optionally interrupt the DSP, allowing the DSP to poll the link status of the device
without continuously performing costly MDIO accesses. For more details on the MDIO, see the
TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO)
Module Reference Guide (literature number SPRU628).
The I2C0 port on the TMS320DM641/DM640 allows the DSP to easily control peripheral devices and
communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may
be used to communicate with serial peripheral interface (SPI) mode peripheral devices.
The DM641/DM640 has a complete set of development tools which includes: a new C compiler, an assembly
optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into
source code execution.

CPU (DSP Core) Description
1.6
CPU (DSP Core) Description
The CPU fetches VelociTI™ advanced very-long instruction words (VLIWs) (256 bits wide) to supply up to
eight 32-bit instructions to the eight functional units during every clock cycle. The VelociTI™ VLIW architecture
features controls by which all eight units do not have to be supplied with instructions if they are not ready to
execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute
packet as the previous instruction, or whether it should be executed in the following clock as a part of the next
execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The
variable-length execute packets are a key memory-saving feature, distinguishing the C64x CPUs from other
VLIW architectures. The C64x™ VelociTI.2™ extensions add enhancements to the TMS320C62x™ DSP
VelociTI™ architecture. These enhancements include:
•
•
•
•
•
•
Register file enhancements
Data path extensions
Quad 8-bit and dual 16-bit extensions with data flow enhancements
Additional functional unit hardware
Increased orthogonality of the instruction set
Additional instructions that reduce code size and increase register flexibility
The CPU features two sets of functional units. Each set contains four units and a register file. One set contains
functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register
files each contain 32 32-bit registers for a total of 64 general-purpose registers. In addition to supporting the
packed 16-bit and 32-/40-bit fixed-point data types found in the C62x™ VelociTI™ VLIW architecture, the
C64x™ register files also support packed 8-bit data and 64-bit fixed-point data types. The two sets of functional
units, along with two register files, compose sides A and B of the CPU [see the functional block and CPU (DSP
core) diagram, and Figure 1−2]. The four functional units on each side of the CPU can freely share the 32
registers belonging to that side. Additionally, each side features a “data cross path”—a single data bus
connected to all the registers on the other side, by which the two sets of functional units can access data from
the register files on the opposite side. The C64x CPU pipelines data-cross-path accesses over multiple clock
cycles. This allows the same register to be used as a data-cross-path operand by multiple functional units in
the same execute packet. All functional units in the C64x CPU can access operands via the data cross path.
Register access by functional units on the same side of the CPU as the register file can service all the units
in a single clock cycle. On the C64x CPU, a delay clock is introduced whenever an instruction attempts to read
a register via a data cross path if that register was updated in the previous clock cycle.
In addition to the C62x™ DSP fixed-point instructions, the C64x™ DSP includes a comprehensive collection
of quad 8-bit and dual 16-bit instruction set extensions. These VelociTI.2™ extensions allow the C64x CPU
to operate directly on packed data to streamline data flow and increase instruction set efficiency. This is a key
factor for video and imaging applications.
Another key feature of the C64x CPU is the load/store architecture, where all instructions operate on registers
(as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data
transfers between the register files and the memory. The data address driven by the .D units allows data
addresses generated from one register file to be used to load or store data to or from the other register file.
The C64x .D units can load and store bytes (8 bits), half-words (16 bits), and words (32 bits) with a single
instruction. And with the new data path extensions, the C64x .D unit can load and store doublewords (64 bits)
with a single instruction. Furthermore, the non-aligned load and store instructions allow the .D units to access
words and doublewords on any byte boundary. The C64x CPU supports a variety of indirect addressing modes
using either linear- or circular-addressing with 5- or 15-bit offsets. All instructions are conditional, and most
can access any one of the 64 registers. Some registers, however, are singled out to support specific
addressing modes or to hold the condition for conditional instructions (if the condition is not automatically
“true”).

June 2003 − Revised April 2005
CPU (DSP Core) Description
The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two
16 × 16-bit multiplies or four 8 ×8-bit multiplies per clock cycle. The .M unit can also perform 16 ×32-bit multiply
operations, dual 16 × 16-bit multiplies with add/subtract operations, and quad 8 × 8-bit multiplies with add
operations. In addition to standard multiplies, the C64x .M units include bit-count, rotate, Galois field multiplies,
and bidirectional variable shift hardware.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle. The arithmetic and logical functions on the C64x CPU include single 32-bit, dual
16-bit, and quad 8-bit operations.
The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory.
The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least
significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous
execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain,
effectively placing the instructions that follow it in the next execute packet. A C64x™ DSP device enhancement
now allows execute packets to cross fetch-packet boundaries. In the TMS320C62x™/TMS320C67x™ DSP
devices, if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in
the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. In the
C64x™ DSP device, the execute boundary restrictions have been removed, thereby, eliminating all of the
NOPs added to pad the fetch packet, and thus, decreasing the overall code size. The number of execute
packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective
functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the
execute packets from the current fetch packet have been dispatched. After decoding, the instructions
simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock
cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes,
half-words, or doublewords. All load and store instructions are byte-, half-word-, word-, or
doubleword-addressable.
For more details on the C64x CPU functional units enhancements, see the following documents:

Bootmode
1.8
Bootmode
The DM641/DM640 device resets using the active-low signal RESET. While RESET is low, the device is held
in reset and is initialized to the prescribed reset state. Refer to reset timing for reset timing characteristics and
states of device pins during reset. The release of RESET starts the processor running with the prescribed
device configuration and boot mode.
The DM641 has three types of boot modes while the DM640 has only two types of boot modes:
•
Host boot [DM641 only]
If host boot is selected, upon release of RESET, the CPU is internally “stalled” while the remainder of the
device is released. During this period, an external host can initialize the CPU’s memory space as
necessary through the host interface, including internal configuration registers, such as those that control
the EMIF or other peripherals. For the DM641 device, the HPI peripheral is used for host boot. Once the
host is finished with all necessary initialization, it must set the DSPINT bit in the HPIC register to complete
the boot process. This transition causes the boot configuration logic to bring the CPU out of the “stalled”
state. The CPU then begins execution from address 0. The DSPINT condition is not latched by the CPU,
because it occurs while the CPU is still internally “stalled”. Also, DSPINT brings the CPU out of the “stalled”
state only if the host boot process is selected. All memory may be written to and read by the host. This
allows for the host to verify what it sends to the DSP if required. After the CPU is out of the “stalled” state,
the CPU needs to clear the DSPINT, otherwise, no more DSPINTs can be received.
•
•
EMIF boot (using default ROM timings)
Upon the release of RESET, the 1K-Byte ROM code located in the beginning of CE1 is copied to address 0
by the EDMA using the default ROM timings, while the CPU is internally “stalled”. The data should be
stored in the endian format that the system is using. In this case, the EMIF automatically assembles
consecutive 8-bit bytes to form the 32-bit instruction words to be copied. The transfer is automatically done
by the EDMA as a single-frame block transfer from the ROM to address 0. After completion of the block
transfer, the CPU is released from the “stalled” state and starts running from address 0.
No boot
With no boot, the CPU begins direct execution from the memory located at address 0. Note: operation is
undefined if invalid code is located at address 0.

These pins are muxed with the GP0 pins and by default these signals function as clocks (CLKOUT4 or CLKOUT6). To use these
muxed pins as GPIO signals, the appropriate GPIO register bits (GPxEN and GPxDIR) must be properly enabled and configured.
For more details, see the Device Configurations section of this data sheet.
‡
These pins are GP0 pins that can also function as external interrupt sources (EXT_INT[7:4]). Default after reset is EXT_INTx or
GPIO as input-only.

For DM641, these McBSP1 and McBSP0 pins are muxed with the Video Port 1 (VP1) and Video Port 0 (VP0) peripherals, respectively. By
default, these signals function as VP1 and VP0, respectively. For more details on these muxed pins, see the Device Configurations section
of this data sheet.
For DM640, these McBSP0 pins are muxed with the Video Port 0 (VP0) peripheral. By default, these signals function as VP0. For more details
on these muxed pins, see the Device Configurations section of this data sheet.
‡
§
The DM640 device does not support the VP1 peripheral; therefore, the McBSP1 peripheral pins are standalone perpheral functions, not
muxed.

The EMU0 and EMU1 pins are internally pulled up with 30-kΩ resistors; therefore, for emulation and normal operation, no external
pullup/pulldown resistors are necessary. However, for boundary scan operation, pull down the EMU1 and EMU0 pins with a dedicated 1-kΩ
resistor.

1.10.2 Device Support
1.10.2.1 Device and Development-Support Tool 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., TMS320DM641GDK600). 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 still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package
type (for example, GDK), the temperature range (for example, blank is the default commercial temperature
range), and the device speed range in megahertz (for example, -600 is 600 MHz). Figure 1−7 provides a
legend for reading the complete device name for any DSP platform member.
The ZDK package, like the GDK package, is a 548-ball plastic BGA only with Pb-free balls. The ZNZ package
is the Pb−free version of the GNZ package.
For device part numbers and further ordering information for TMS320DM641/DM640 in the GDK, GNZ, ZDK
and ZNZ package types, see the TI website (http://www.ti.com) or contact your TI sales representative.

via the peripheral configurations register (PERCFG) [address location 0x01B3F000] after device reset.
2.1
Configurations at Reset
For proper device operation; the following external pins must be configured correctly:
•
•
•
For proper DM641 device operation, the HD5 [pin Y1] at device reset must be pulled down via a 10-kΩ
resistor.
For proper DM641/DM640 device operation, the reserved (RSV) [E2] pin at device reset must be pulled
down via a 10-kΩ resistor.
For proper DM641/DM640 device operation, the GP0[0] [pin M5] (IPD) must remain low at device reset.
2.1.1
Peripheral Selection at Device Reset
On the DM641/DM640 devices there are NO peripherals sharing the same pins (internally muxed, yet mutually
exclusive) that are controlled via external pins.
•
EMAC and MDIO peripherals
The MAC_EN pin is latched at reset. This pin determines specific peripheral selection, summarized in
Table 2−1.

Peripheral Selection After Device Reset
Video Ports, McBSP1, McBSP0, McASP0, and I2C0
The DM641/DM640 device has designated registers for peripheral configuration (PERCFG), device status
(DEVSTAT), and JTAG identification (JTAGID). These registers are part of the Device Configuration module
and are mapped to a 4K block memory starting at 0x01B3F000. The CPU accesses these registers via the
CFGBUS.
The peripheral configuration register (PERCFG), allows the user to control the peripheral selection of the
Video Ports (VP0 and VP1 [DM641 only]) McBSP0, McBSP1, McASP0, and I2C0 peripherals. For more
detailed information on the PERCFG register control bits, see Figure 2−1 and Table 2−3.

Peripheral Configuration Lock
By default, the McASP0, VP0, VP1 [DM641 only], and I2C peripherals are disabled on power up. In order to
use these peripherals on the DM641/DM640 device, the peripheral must first be enabled in the Peripheral
Configuration register (PERCFG). Software muxed pins should not be programmed to switch
functionalities during run-time. Care should also be taken to ensure that no accesses are being
performed before disabling the peripherals. To help minimize power consumption in the DM641/DM640
device, unused peripherals may be disabled.
Figure 2−3 shows the flow needed to enable (or disable) a given peripheral on the DM641/DM640 devices.

A 32-bit key (value = 0x10C0010C) must be written to the Peripheral Configuration Lock register
(PCFGLOCK) in order to unlock access to the PERCFG register. Reading the PCFGLOCK register
determines whether the PERCFG register is currently locked (LOCKSTAT bit = 1) or unlocked (LOCKSTAT
bit = 0), see Figure 2−4. A peripheral can only be enabled when the PERCFG register is “unlocked”
(LOCKSTAT bit = 0).

LOCK
Any write to the PERCFG register will automatically relock the register. In order to avoid the unnecessary
overhead of multiple unlock/enable sequences, all peripherals should be enabled with a single write to the
PERCFG register with the necessary enable bits set.
Prior to waiting 128 CPU cycles, the PERCFG register should be read. There is no direct correlation between
the CPU issuing a write to the PERCFG register and the write actually occurring. Reading the PERCFG
register after the write is issued forces the CPU to wait for the write to the PERCFG register to occur.
Once a peripheral is enabled, the DSP (or other peripherals such as the HPI) must wait a minimum of 128 CPU
cycles before accessing the enabled peripheral. The user must ensure that no accesses are performed to a
peripheral while it is disabled.

Multiplexed Pin Configurations
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Some
of these pins are configured by software, and the others are configured by external pullup/pulldown resistors
only at reset. Those muxed pins that are configured by software should not be programmed to switch
functionalities during run-time. Those muxed pins that are configured by external pullup/pulldown resistors
are mutually exclusive; only one peripheral has primary control of the function of these pins after reset.
Table 2−7 identifies the multiplexed pins on the DM641/DM640 device; shows the default (primary) function
and the default settings after reset; and describes the pins, registers, etc. necessary to configure specific
multiplexed functions.

Debugging Considerations
It is recommended that external connections be provided to device configuration pins, including
TOUT1/LENDIAN, AEA[22:19] and TOUT0/MAC_EN. Although internal pullup/pulldown resistors exist on
these pins, providing external connectivity adds convenience to the user in debugging and flexibility in
switching operating modes.
Internal pullup/pulldown resistors also exist on the non-configuration pins on the AEA bus (AEA[18:0]). Do not
oppose the internal pullup/pulldown resistors on these non-configuration pins with external pullup/pulldown
resistors. If an external controller provides signals to these non-configuration pins, these signals must be
driven to the default state of the pins at reset, or not be driven at all.
For the internal pullup/pulldown resistors for all device pins, see the terminal functions table.

Future variants of the C64x DSPs may operate at voltages ranging from 0.9 V to 1.4 V to provide a range of system power/performance options.
TI highly recommends that users design-in a supply that can handle multiple voltages within this range (i.e., 1.2 V, 1.25 V, 1.3 V, 1.35 V, 1.4 V
with 3% tolerances) by implementing simple board changes such as reference resistor values or input pin configuration modifications. Examples
of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 series from Power Trends, a subsidiary of Texas Instruments. Not
incorporating a flexible supply may limit the system’s ability to easily adapt to future versions of C64x devices.
The absolute maximum ratings should not be exceeded for more than 30% of the cycle period.

Parameter Information
4.1.1.3 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.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device
and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time
margin, but also tends to improve the input hold time margins (see Table 4−1 and Figure 4−4).
Figure 4−4 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.

4.3.1
Power-Supply Sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time
(>1 second) if the other supply is below the proper operating voltage.
4.3.2
Power-Supply Design Considerations
A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O
power up. A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 4−5).

Figure 4−5. Schottky Diode Diagram
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the C6000™ platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.
4.3.3
Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to the DSP. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for the
core supply and 30 for the I/O supply. These caps need to be close to the DSP 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 (32 total)
be placed immediately next to the BGA vias, using the “interior” BGA space and at least the corners of the
“exterior”.
Eight larger caps (4 for each supply) can be placed further away for bulk decoupling. Large bulk caps (on the
order of 100 µF) should be furthest away (but still as close as possible). No less than 4 large caps per supply
(8 total) should be placed outside of the BGA.
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.

Peripheral Power-Down Operation
The DM641/DM640 device can be powered down in three ways:
•
•
Power-down due to pin configuration
Power-down due to software configuration − relates to the default state of the peripheral configuration bits
in the PERCFG register.
•
Power-down during run-time via software configuration
On the DM641/DM640 device, the EMAC and MDIO peripherals are controlled (selected) at the pin level
during chip reset (e.g., using the MAC_EN pin).
The McASP0, McBSP0, McBSP1, VP0, VP1 [DM641 only], and I2C0 peripheral functions are selected via the
peripheral configuration (PERCFG) register bits.
For more detailed information on the peripheral configuration pins and the PERCFG register bits, see the
Device Configurations section of this document.

Triggering, Wake-up, and Effects
The power-down modes and their wake-up methods are programmed by setting the PWRD field (bits 15−10)
of the control status register (CSR). The PWRD field of the CSR is shown in Figure 4−7 and described in
Table 4−2. When writing to the CSR, all bits of the PWRD field should be set at the same time. Logic 0 should
be used when writing to the reserved bit (bit 15) of the PWRD field. The CSR is discussed in detail in the
TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189).

bit fields in the CSR register, see the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189).
Figure 4−7. PWRD Field of the CSR Register
A delay of up to nine clock cycles may occur after the instruction that sets the PWRD bits in the CSR before the
PD mode takes effect. As best practice, NOPs should be padded after the PWRD bits are set in the CSR to
account for this delay.
If PD1 mode is terminated by a non-enabled interrupt, the program execution returns to the instruction where
PD1 took effect. If PD1 mode is terminated by an enabled interrupt, the interrupt service routine will be executed
first, then the program execution returns to the instruction where PD1 took effect. In the case with an enabled
interrupt, the GIE bit in the CSR and the NMIE bit in the interrupt enable register (IER) must also be set in order
for the interrupt service routine to execute; otherwise, execution returns to the instruction where PD1 took effect
upon PD1 mode termination by an enabled interrupt.
PD2 and PD3 modes can only be aborted by device reset. Table 4−2 summarizes all the power-down modes.

Input clock to the PLL stops generating clocks. All register and

When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or
peripherals with an external clock source, output signals may transition in response to stimulus on the inputs. Under these conditions,
peripherals will not operate according to specifications.
4.3.7
C64x Power-Down Mode with an Emulator
If user power-down modes are programmed, and an emulator is attached, the modes will be masked to allow
the emulator access to the system. This condition prevails until the emulator is reset or the cable is removed
from the header. If power measurements are to be performed when in a power-down mode, the emulator cable
should be removed.
When the DSP is in power-down mode PD2 or PD3, emulation logic will force any emulation execution
command (such as Step or Run) to spin in IDLE. For this reason, PC writes (such as loading code) will fail.
A DSP reset will be required to get the DSP out of PD2/PD3.

Enhanced Direct Memory Access (EDMA) Controller
The EDMA controller handles all data transfers between the level-two (L2) cache/memory controller and the

memory accesses, user-programmed data transfers, and host accesses.

EDMA Device-Specific Information
4.4.1.1 EDMA Channel Synchronization Events
The C64x EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 4−3 lists the source of C64x EDMA synchronization events associated with each of the programmable
EDMA channels. For the DM641/DM640 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 (ERL, ERH) even if the events are disabled by the EDMA event enable registers (EERL,
EERH). The priority of each event can be specified independently in the transfer parameters stored in the
EDMA parameter RAM. For more detailed information on the EDMA module and how EDMA events are
enabled, captured, processed, linked, chained, and cleared, etc., see the TMS320C6000 DSP Enhanced

Interrupt Sources and Interrupt Selector
The C64x DSP core supports 16 prioritized interrupts, which are listed in Table 4−7. The highest-priority
interrupt is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00−INT_03) are non-maskable and fixed. The remaining interrupts (INT_04−INT_15) are maskable and
default to the interrupt source specified in Table 4−7. The interrupt source for interrupts 4−15 can be
programmed by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector
Control registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

Reset
A hardware reset (RESET) is required to place the DSP into a known good state out of power-up. The RESET
signal can be asserted (pulled low) prior to ramping the core and I/O voltages or after the core and I/O voltages
have reached their proper operating conditions. As a best practice, reset should be held low during power-up.
Prior to deasserting RESET (low-to-high transition), the core and I/O voltages should be at their proper
operating conditions and CLKIN should also be running at the correct frequency.
For information on peripheral selection at the rising edge of RESET, see the Device Configuration section of
this data manual.

Clock PLL
4.7
Clock PLL
The PLL controller features hardware-configurable PLL multiplier controller, dividers (/2, /4, /6, and /8), and
reset controller. The PLL controller accepts an input clock, as determined by the logic state on the
CLKMODE[1:0] pins, from the CLKIN pin. The resulting clock outputs are passed to the DSP core, peripherals,
and other modules inside the C6000™ DSP.
4.7.1
Clock PLL Device-Specific Information
Most of the internal C64x™ DSP clocks are generated from a single source through the CLKIN pin. This source
clock either drives the PLL, which multiplies the source clock frequency to generate the internal CPU clock,
or bypasses the PLL to become the internal CPU clock.
To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed.
Figure 4−10 shows the external PLL circuitry for either x1 (PLL bypass) or other PLL multiply modes.
To minimize the clock jitter, a single clean power supply should power both the C64x™ DSP device and the
external clock oscillator circuit. The minimum CLKIN rise and fall times should also be observed. For the input
clock timing requirements, see the input and output clocks electricals section.
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock source
must meet the DSP requirements in this data sheet (see the electrical characteristics over recommended
ranges of supply voltage and operating case temperature table and the input and output clocks electricals
section).

NOTES: A. Place all PLL external components (C1, C2, and the EMI Filter) as close to the C6000™ DSP device as possible. For the best
performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or
components other than the ones shown.
B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (C1, C2, and the EMI
Filter).
C. The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DV
.

These clock frequency range values are applicable to a DM641−600 speed device. For −400, −500 device speed values, see the CLKIN timing
requirements table for the specific device speed.
Use external pullup resistors on the CLKMODE pins (CLKMODE1 and CLKMODE0) to set the DM641/DM640 device to one of the valid PLL
multiply clock modes (x6 or x12). With internal pulldown resistors on the CLKMODE pins (CLKMODE1, CLKMODE0), the default clock mode
is x1 (bypass).
Under some operating conditions, the maximum PLL lock time may vary by as much as 150% from the specified typical value. For example, if
the typical lock time is specified as 100 µs, the maximum value may be as long as 250 µs.

The reference points for the rise and fall transitions are measured at V MAX and V MIN.
E = the EMIF input clock (AECLKIN, CPU/4 clock, or CPU/6 clock) period in ns for EMIFA.
Minimum AECLKIN cycle times must be met, even when AECLKIN is generated by an internal clock source. Minimum AECLKIN times are based
on internal logic speed; the maximum useable speed of the EMIF may be lower due to AC timing requirements. On the 600 device, 133-MHz
operation is achievable if the requirements of the EMIF Device Speed section are met. On the 400 and 500 devices, 100-MHz operation is
achievable if the requirements of the EMIF Device Speed section are met.

External Memory Interface (EMIIF)
4.8
External Memory Interface (EMIIF)
EMIF supports a glueless interface to a variety of external devices, including:
•
•
•
•
Pipelined synchronous-burst SRAM (SBSRAM)
Synchronous DRAM (SDRAM)
Asynchronous devices, including SRAM, ROM, and FIFOs
An external shared-memory device
4.8.1
EMIF Device-Specific Information
EMIF Device Speed
The rated EMIF speed of these devices only applies to the SDRAM interface when in a system that meets the
following requirements:
•
•
•
•
•
1 chip-enable (CE) space (maximum of 2 chips) of SDRAM connected to EMIF
up to 1 CE space of buffers connected to EMIF
EMIF trace lengths between 1 and 3 inches
166-MHz SDRAM for 133-MHz operation
143-MHz SDRAM for 100-MHz operation
Other configurations may be possible, but timing analysis must be done to verify all AC timings are met.
Verification of AC timings is mandatory when using configurations other than those specified above. TI
recommends utilizing I/O buffer information specification (IBIS) to analyze all AC timings.
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).
To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (see
the Terminal Functions table for the EMIF output signals).
For more detailed information on the DM641/DM640 EMIF peripheral, see the TMS320C6000 DSP External
Memory Interface (EMIF) Reference Guide (literature number SPRU266).

To ensure data setup time, simply program the strobe width wide enough. AARDY is internally synchronized. The AARDY signal is only
recognized two cycles before the end of the programmed strobe time and while AARDY is low, the strobe time is extended cycle-by-cycle. When
AARDY is recognized low, the end of the strobe time is two cycles after AARDY is recognized high. To use AARDY as an asynchronous input,
the pulse width of the AARDY signal should be wide enough (e.g., pulse width = 2E) to ensure setup and hold time is met.
RS = Read setup, RST = Read strobe, RH = Read hold, WS = Write setup, WST = Write strobe, WH = Write hold. These parameters are

The EKxHZ bits in the EMIF Global Control register (GBLCTL) determine the state of the ECLKOUTx signals during HOLDA. If EKxHZ = 0,
ECLKOUTx continues clocking during Hold mode. If EKxHZ = 1, ECLKOUTx goes to high impedance during Hold mode, as shown in Figure 4−30.
All pending EMIF transactions are allowed to complete before HOLDA is asserted. If no bus transactions are occurring, then the minimum delay
time can be achieved. Also, bus hold can be indefinitely delayed by setting NOHOLD = 1.

Multichannel Audio Serial Port (McASP0) Peripheral
4.9
Multichannel Audio Serial Port (McASP0) Peripheral
The McASP functions as a general-purpose audio serial port optimized for the needs of multichannel audio
applications. The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated Sound (I2S)
protocols, and intercomponent digital audio interface transmission (DIT).
4.9.1
McASP0 Device-Specific Information
The TMS320DM641/DM640 device includes one multichannel audio serial port (McASP) interface peripheral
(McASP0). The McASP is a serial port optimized for the needs of multichannel audio applications.
The McASP consists of a transmit and receive section. These sections can operate completely independently
with different data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit
and receive sections may be synchronized. The McASP module also includes a pool of 16 shift registers that
may be configured to operate as either transmit data, receive data, or general-purpose I/O (GPIO).
The transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM) synchronous
serial format or in a digital audio interface (DIT) format where the bit stream is encoded for S/PDIF, AES-3,
IEC-60958, CP-430 transmission. The receive section of the McASP supports the TDM synchronous serial
format.
The McASP can support one transmit data format (either a TDM format or DIT format) and one receive format
at a time. All transmit shift registers use the same format and all receive shift registers use the same format.
However, the transmit and receive formats need not be the same.
Both the transmit and receive sections of the McASP also support burst mode which is useful for non-audio
data (for example, passing control information between two DSPs).
The McASP peripheral has additional capability for flexible clock generation, and error detection/handling, as
well as error management.
For more detailed information on and the functionality of the McASP peripheral, see the TMS320C6000 DSP
Multichannel Audio Serial Port (McASP) Reference Guide (literature number SPRU041).
4.9.1.1 McASP Block Diagram
Figure 4−32 illustrates the major blocks along with external signals of the TMS320DM641/DM640 McASP0
peripheral; and shows the 8 serial data [AXR] pins. The McASP also includes full general-purpose I/O (GPIO)
control, so any pins not needed for serial transfers can be used for general-purpose I/O.

Host-Port Interface (HPI) [DM641 Only]
4.11 Host-Port Interface (HPI) [DM641 Only]
The HPI is a parallel port through which a host processor can directly access the CPU memory space. The
host device functions as a master to the interface, which increases ease of access. The host and CPU can
exchange information via internal or external memory. The host also has direct access to memory-mapped
peripherals. Connectivity to the CPU memory space is provided through the enhanced DMA (EDMA)
controller. Both the host and the CPU can access the HPI control register (HPIC) and the HPI address register
(HPIA). The host can access the HPI data register (HPID) and the HPIC by using the external data and
interface control signals.
For more detailed information on the HPI peripheral, see the TMS320C6000 DSP Host Port Interface (HPI)
Reference Guide (literature number SPRU578).

HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
This parameter is used during HPID reads and writes. For reads, at the beginning of the first half-word transfer (HPI16) on the falling edge of
HSTROBE, the HPI sends the request to the EDMA internal address generation hardware, and HRDY remains high until the EDMA internal
address generation hardware loads the requested data into HPID. For writes, HRDY goes high if the internal write buffer is full.

P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
For all SPI Slave modes, CLKG is programmed as 1/4 of the CPU clock by setting CLKSM = CLKGDV = 1.

Sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)

H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even

FSRP = FSXP = 1. As a SPI Master, FSX is inverted to provide active-low slave-enable output. As a Slave, the active-low signal input on FSX
and FSR is inverted before being used internally.

Video Port
4.13 Video Port
Each Video Port is capable of sending and receiving digital video data. The Video Ports are also capable of
capturing/displaying RAW data. The Video Port peripherals follow video standards such as CCIR601 and
ITU-BT.656.
4.13.1 Video Port Device-Specific Information
The TMS320DM641 device has two video port peripherals [VP0 and VP1]. The TMS320DM640 device only
supports one video port peripheral [VP0].
The video port peripheral can operate as a video capture port, video display port, or as a transport stream
interface (TSI) capture port.
The port consists of a single channel A. A 2560-byte capture/display buffer is utilized on this channel. The port
is always configured for either video capture or display only. Separate data pipelines control the parsing and
formatting of video capture or display data for each of the BT.656, raw video, and TSI modes.
For video capture operation, the video port may operate as a single channel of 8-bit BT.656, 8-bit raw video,
or 8-bit TSI.
For video display operation, the video port may operate as 8-bit BT.656 or 8-bit raw video.
Note: The following Video Port mode currently is not supported:
•
8-Bit Transport Stream Interface (TSI) capture port [TSI currently not supported]
For more detailed information on the DM641 and DM640 Video Port peripherals, see the TMS320C64x DSP
Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number SPRU629).

VCXO Interpolated Control (VIC)
4.14 VCXO Interpolated Control (VIC)
The VIC can be used in conjunction with the Video Ports (VPs) to maintain synchronization of a video stream.
The VIC can also be used to control a VCXO to adjust the pixel clock rate to a video port.
4.14.1 VIC Device-Specific Information
The VCXO interpolated control (VIC) port provides digital-to-analog conversation with resolution from 9-bits
to up to 16-bits. The output of the VIC is a single bit interpolated D/A output (VDAC pin).
Typical D/A converters provide a discrete output level for every value of the digital word that is being converted.
This is a problem for digital words that are long. This is avoided in a Sigma Delta type D/A converter by
choosing a few widely spaced output levels and interpolating values between them. The interpolating
mechanism causes the output to oscillate rapidly between the levels in such a manner that the average output
represents the value of input code.
In the VIC, two output levels are chosen (0 and 1), and Sigma Delta interpolation scheme is implemented to
interpolate between these levels with a rapidly changing signal. The frequency of interpolation is dependent
on the resolution needed.
When the video port is used in transport stream interface (TSI) mode [currently not supported], the VIC port
is used to control the system clock, VCXO, for MPEG transport stream.
The VIC supports the following features:
•
•
•
Single interpolation for D/A conversion
Programmable precision from 9-to-16 bits
Interface for register accesses
For more detailed information on the DM641 and DM640 VCXO interpolated control (VIC) peripheral, see the
TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number

Ethernet Media Access Controller (EMAC)
4.15 Ethernet Media Access Controller (EMAC)
The EMAC controls the flow of packet data from the DSP to the PHY.
4.15.1 EMAC Device-Specific Information
The ethernet media access controller (EMAC) provides an efficient interface between the DM641/DM640 DSP
core processor and the network. The DM641/DM640 EMAC support both 10Base-T and 100Base-TX, or 10
Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality of
service (QOS) support. The DM641/DM640 EMAC makes use of a custom interface to the DSP core that
allows efficient data transmission and reception.
The EMAC controls the flow of packet data from the DSP to the PHY. The MDIO module controls PHY
configuration and status monitoring.
Both the EMAC and the MDIO modules interface to the DSP 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 control device reset,
interrupts, and system priority.
TheTMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO)
Module Reference Guide (literature number SPRU628) describes the DM641/DM640 EMAC peripheral in
detail. Some of the features documented in this peripheral reference guide are not supported on the
DM641/DM640 at this time. The DM641/DM640 supports one receive channel and does not support receive
quality of service (QOS). For a list of supported registers and register fields, see Table 4−63 [Ethernet MAC
(EMAC) Control Registers] and Table 4−64 [EMAC Statistics Registers] in this data manual.

Management Data Input/Output (MDIO)
4.16 Management Data Input/Output (MDIO)
The MDIO module controls PHY configuration and status monitoring.
4.16.1 Device-Specific Information
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.
TheTMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO)
Module Reference Guide (literature number SPRU628) describes the DM641/DM640 MDIO peripheral in
detail. Some of the features documented in this peripheral reference guide are not supported on the
DM641/DM640 at this time. The DM641/DM640 only supports one EMAC module. For a list of supported
registers and register fields, see Table 4−71 [MDIO Registers] in this data manual.

4.17 Timer
The C6000™ DSP device has 32-bit general-purpose timers that can be used to:
•
•
•
•
•
Time events
Count events
Generate pulses
Interrupt the CPU
Send synchronization events to the DMA
The timers have two signaling modes and can be clocked by an internal or an external source. The timers have
an input pin and an output pin. The input and output pins (TINP and TOUT) can function as timer clock input
and clock output. They can also be respectively configured for general-purpose input and output.
With an internal clock, for example, the timer can signal an external A/D converter to start a conversion, or
it can trigger the DMA controller to begin a data transfer. With an external clock, the timer can count external
events and interrupt the CPU after a specified number of events.
4.17.1 Timer Device-Specific Information
The DM641/DM640 device has a total of three 32-bit general-purpose timers (Timer0, Timer1, and Timer2).
Timer2 is not externally pinned out.
For more detailed information, see the TMS320C6000 DSP 32-Bit Timer Reference Guide (literature number
SPRU582).

General-Purpose Input/Output (GPIO)
4.18 General-Purpose Input/Output (GPIO)
The GPIO peripheral provides dedicated general-purpose pins that can be configured as either inputs or
outputs. When configured as an output, you can write to an internal register to control the state driven on the
output pin. When configured as an input, you can detect the state of the input 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.
4.18.1 GPIO Device-Specific Information
To use the GP[7:0] software-configurable GPIO pins, the GPxEN bits in the GP Enable (GPEN) Register and
the GPxDIR bits in the GP Direction (GPDIR) Register must be properly configured.
GPxEN =
GPxDIR =
GPxDIR =

GP[x] pin is enabled

GP[x] pin is an output
where “x” represents one of the 7 through 0 GPIO pins
Figure 4−61 shows the GPIO enable bits in the GPEN register for the DM641/DM640 device. To use any of
the GPx pins as general-purpose input/output functions, the corresponding GPxEN bit must be set to “1”
(enabled). Default values are device-specific, so refer to Figure 4−61 for the DM641/DM640 default
configuration.

P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
The pulse width given is sufficient to generate a CPU interrupt or an EDMA event. However, if a user wants to have the DSP recognize the GPIx
changes through software polling of the GPIO register, the GPIx duration must be extended to at least 12P to allow the DSP enough time to access
the GPIO register through the CFGBUS.

4.19 JTAG
The JTAG interface is used for BSDL testing and emulation of the DM641/DM640 device.
4.19.1 JTAG Device-Specific Information
4.19.1.1 IEEE 1149.1 JTAG Compatibility Statement
The TMS320DM641/DM640 DSP requires that both TRST and RESET be asserted upon power up to be
properly initialized. While RESET initializes the DSP core, TRST initializes the DSP’s emulation logic. Both
resets are required for proper operation.
Note: TRST is synchronous and must be clocked by TCLK; otherwise, BSCAN may not respond as expected
after TRST is asserted.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the
DSP to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface
and DSP’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 DSP or exercise the DSP’s boundary scan functionality. RESET must be
released 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 TMS320DM641/DM640 DSP includes an internal pulldown (IPD) on the TRST
pin to ensure that TRST will always be asserted upon power up and the DSP’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 intialize the DSP after powerup 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 occur to latch the state of EMU1 and
EMU0. The EMU[1:0] pins configure the device for either Boundary Scan mode or Normal/Emulation mode.
For more detailed information, see the terminal functions section of this data sheet.
Note: The DESIGN_WARNING section of the TMS320DM641/DM640 BSDL file contains information and
constraints regarding proper device operation while in Boundary Scan Mode.
For more detailed information on the DM641 and DM640 JTAG emulation, see the TMS320C6000 DSP
Designing for JTAG Emulation Reference Guide (literature number SPRU641).
4.19.1.2 JTAG ID Register Description
The JTAG ID register is a read-only register that identifies to the customer the JTAG/Device ID. For the
DM641/DM640 device, the JTAG ID register resides at address location 0x01B3 F008. The register hex value
for the DM641/DM640 device is: 0x0007 902F. For the actual register bit names and their associated bit field
