SPRS269B – FEBRUARY 2005 – REVISED OCTOBER 2005
1.2
Description
The TMS320C64x™ DSPs (including the TMS320DM643 device) are the highest-performance fixed-point
DSP generation in the TMS320C6000™ DSP platform. The TMS320DM643 (DM643) device is 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
DM643 device offers cost-effective solutions to high-performance DSP programming challenges. The
DM643 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 DM643 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 DM643 DSP also has application-specific hardware logic, on-chip memory,
and additional on-chip peripherals similar to the other C6000™ DSP platform devices.
The DM643 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 an 2-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; a
10/100 Mb/s Ethernet MAC (EMAC); a management data input/output (MDIO) module; a VCXO
interpolated control port (VIC); one multichannel buffered audio serial port (McASP0); an inter-integrated
circuit (I2C) Bus module; one multichannel buffered serial port (McBSP); three 32-bit general-purpose
timers; a user-configurable 16-bit or 32-bit host-port interface (HPI16/HPI32); a 16-pin general-purpose
input/output port (GP0) with programmable interrupt/event generation modes; and a 64-bit glueless
external memory interface (EMIFA), which is capable of interfacing to synchronous and asynchronous
memories and peripherals.
The DM643 device has two configurable video port peripherals (VP1 and VP2). These video port
peripherals provide a glueless interface to common video decoder and encoder devices. The DM643
video port peripherals support multiple resolutions and video standards (e.g., CCIR601, ITU-BT.656,
BT.1120, SMPTE 125M, 260M, 274M, and 296M).
These two video port peripherals are configurable and can support either video capture and/or video
display modes. Each video port consists of two channels — A and B with a 5120-byte capture/display
buffer that is splittable between the two channels.
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 eight 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 DM643 has sufficient bandwidth to support all 8 serial data pins
transmitting a 192-kHz stereo signal. Serial data in each zone may be transmitted and received on
multiple serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC
Sound (I2S) format.
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.

SPRS269B – FEBRUARY 2005 – REVISED OCTOBER 2005
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 DM643 DSP
core processor and the network. The DM643 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 DM643 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 TMS320DM643 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 DM643 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.
1.2.1

2.2
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 2-1]. 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").

SPRS269B – FEBRUARY 2005 – REVISED OCTOBER 2005
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:
• TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189)
• TMS320C64x Technical Overview (literature number SPRU395)

Bootmode
The DM643 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 DM643 has three types of boot modes:
• Host boot
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. 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.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the
opposite supply rail, a 1-kΩ resistor should be used.)
These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
PLLV is not part of external voltage supply. See the Clock PLL section for information on how to connect this pin.
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.

use of an external pullup/pulldown resistor.
Boot Configuration:
• HD5 pin = 0: HPI operates as an HPI16.
(HPI bus is 16 bits wide. HD[15:0] pins are used and the remaining
HD[31:16] pins are reserved pins in the high-impedance state.)
• HD5 pin = 1: HPI operates as an HPI32.
(HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.)
I/O/Z
For superset devices like DM643, the HD31 through HD16 pins can also function
as EMAC transmit/receive or control pins (when MAC_EN pin = 1). For more
details on the EMAC pin functions, see the Ethernet MAC (EMAC) peripheral
section of this table and for more details on how to configure the EMAC pin
functions, see the device configuration section of this data sheet.

• Enabled by bits 28 through 31 of the word address
• Only one pin is asserted during any external data access
EMIFA byte-enable control
• Decoded from the low-order address bits. The number of address bits or
byte enables used depends on the width of external memory.
• Byte-write enables for most types of memory
• Can be directly connected to SDRAM read and write mask signal (SDQM)

Device Support
2.6.2.1
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., TMS320DM643GDK500). 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.

SPRS269B – FEBRUARY 2005 – REVISED OCTOBER 2005
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, 500 is 500 MHz). Figure 2-15
provides a legend for reading the complete device name for any TMS320C6000™ DSP platform member.
The ZDK package, like the GDK package, is a 548-ball plastic BGA only with Pb-free balls. The ZNZ is the
Pb-free package version of the GNZ package.
For device part numbers and further ordering information for TMS320DM643 in the GDK, GNZ, ZDK, and
ZNZ package types, see the TI website (http://www.ti.com) or contact your TI sales representative.

Device Configurations
On the DM643 device, bootmode and certain device configurations/peripheral selections are determined at
device reset, while other device configurations/peripheral selections are software-configurable via the
peripheral configurations register (PERCFG) [address location 0x01B3F000] after device reset.
3.1
Configurations at Reset
For proper DM643 device operation, the following external pins must be configured correctly:
• The GP0[0] (pin M5) must remain low, do not oppose the internal pulldown (IPD).
• The RSV09 (pin E2) at device reset must be pulled down via a 10-kΩ resistor.
3.1.1
Peripheral Selection at Device Reset
Some DM643 peripherals share the same pins (internally muxed) and are mutually exclusive (i.e., HPI,
EMAC, and MDIO). Other DM643 peripherals (i.e., the Timers, I2C0, GP0, McBSP0, and VP2), are
always available.
• HPI, EMAC, and MDIO peripherals
The MAC_EN pin is latched at reset and determines specific peripheral selection, summarized in
Table 3-1. For further clarification of the HPI vs. EMAC configuration, see Table 3-2.

Video Ports, McBSP0, McASP0 and I2C0
The DM643 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 (VP1 and VP2) McBSP0, McASP0, and I2C0 peripherals. For more detailed information on
the PERCFG register control bits, see Figure 3-1 and Table 3-4.

Peripheral Configuration Lock
By default, the McASP0, VP1, VP2, and I2C peripherals are disabled on power up. In order to use these
peripherals on the DM643 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 DM643 device, unused
peripherals may be disabled.
Figure 3-3 shows the flow needed to enable (or disable) a given peripheral on the DM643 device.

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 3-4. A peripheral can only be enabled when the PERCFG register is
"unlocked" (LOCKSTAT bit = 0).

NAME
LOCK
DESCRIPTION
Lock bits.
0x10C0010C = Unlocks PERCFG register accesses.
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 3-8 identifies the multiplexed pins on the DM643 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], HD5, 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.

Measured with average activity (50% high/50% low power) at 25°C case temperature and 133-MHz EMIF for -600 speed (100-MHz
EMIF for -500 speed). This model represents a device performing high-DSP-activity operations 50% of the time, and the remainder
performing low-DSP-activity operations. The high/low-DSP-activity models are defined as follows:
• High-DSP-Activity Model:
– CPU: 8 instructions/cycle with 2 LDDW instructions [L1 Data Memory: 128 bits/cycle via LDDW instructions;
L1 Program Memory: 256 bits/cycle; L2/EMIF EDMA: 50% writes, 50% reads to/from SDRAM (50% bit-switching)]
– McBSP: 1 channel at 2.048 MHz
– Timers: 2 timers at maximum rate
• Low-DSP-Activity Model:
– CPU: 2 instructions/cycle with 1 LDH instruction [L1 Data Memory: 16 bits/cycle; L1 Program Memory: 256 bits per 4 cycles;
L2/EMIF EDMA: None]
– McBSP: 1 channel at 2.048 MHz
– Timers: 2 timers at maximum rate
The actual current draw is highly application-dependent. For more details on core and I/O activity, refer to the TMS320DMx Power

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 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.

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 5-1 and Figure 5-6).
Figure 5-6 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.

Power Supplies
For more information regarding TI's power management products and suggested devices to power TI
DSPs, visit www.ti.com/dsppower.
5.3.1
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.
5.3.2
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 5-7).

Figure 5-7. 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.
5.3.3
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.

5.3.4
Peripheral Power-Down Operation
The DM643 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 DM643 device, the HPI and EMAC and MDIO peripherals are controlled (selected) at the pin level
during chip reset (e.g., HD5 and MAC_EN pins).
The McASP0, McBSP0, VP1, VP2, 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.

5.3.6
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 5-9 and
described in Table 5-2. 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).

NOTE: The shaded bits are not part of the power-down logic discussion and therefore are not covered here. For information on these other
bit fields in the CSR register, see the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189).
Figure 5-9. 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 5-2 summarizes all the power-down
modes.

WAKE-UP METHOD
—
EFFECT ON CHIP'S OPERATION
—
CPU halted (except for the interrupt logic)
Power-down mode blocks the internal clock inputs at the
boundary of the CPU, preventing most of the CPU's logic from
switching. During PD1, EDMA transactions can proceed
between peripherals and internal memory.
Wake by a device reset
Output clock from PLL is halted, stopping the internal clock
structure from switching and resulting in the entire chip being
halted. All register and internal RAM contents are preserved. All
functional I/O "freeze" in the last state when the PLL clock is
turned off.
Wake by a device reset
Input clock to the PLL stops generating clocks. All register and
internal RAM contents are preserved. All functional I/O "freeze"
in the last state when the PLL clock is turned off. Following
reset, the PLL needs time to re-lock, just as it does following
power-up.
Wake-up from PD3 takes longer than wake-up from PD2
because the PLL needs to be re-locked, just as it does following
power-up.
—
—
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.
5.3.7
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 device peripherals on the DM643 DSP. These data transfers include cache servicing, non-cacheable
memory accesses, user-programmed data transfers, and host accesses.
5.4.1
EDMA Device-Specific Information
5.4.1.1
EDMA Channel Synchronization Events
The C64x EDMA supports up to 64 EDMA channels which service peripheral devices and external
memory. Table 5-3 lists the source of C64x EDMA synchronization events associated with each of the
programmable EDMA channels. For the DM643 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 Direct Memory Access (EDMA) Controller Reference Guide (literature
number SPRU234).

Interrupts
5.5.1
Interrupt Sources and Interrupt Selector
The C64x DSP core supports 16 prioritized interrupts, which are listed in Table 5-7. 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 5-7. 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.

5.7
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.
5.7.1
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 5-12 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: 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.
For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (C1, C2, and
the EMI Filter).
The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DVDD.

These clock frequency range values are applicable to a DM643-600 speed device. For -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 DM643 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.

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
5.8.1
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 DM643 EMIF peripheral, see the TMS320C6000 DSP External

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 programmed via the EMIF CE space control registers.

The following parameters are programmable via the EMIF CE Space Secondary Control register (CExSEC):
• Read latency (SYNCRL): 0-, 1-, 2-, or 3-cycle read latency
• Write latency (SYNCWL): 0-, 1-, 2-, or 3-cycle write latency
• ACEx assertion length (CEEXT): For standard SBSRAM or ZBT SRAM interface, ACEx goes inactive after the final command has
been issued (CEEXT = 0). For synchronous FIFO interface with glue, ACEx is active when ASOE is active (CEEXT = 1).
• Function of ASADS/ASRE (RENEN): For standard SBSRAM or ZBT SRAM interface, ASADS/ASRE acts as ASADS with deselect
cycles (RENEN = 0). For FIFO interface, ASADS/ASRE acts as ASRE with NO deselect cycles (RENEN = 1).
• Synchronization clock (SNCCLK): Synchronized to AECLKOUT1 or AECLKOUT2

APDT signal is only asserted when the EDMA is in PDT mode (set the PDTS bit to 1 in the EDMA options parameter RAM). For APDT read,
data is not latched into EMIF. The PDTRL field in the PDT control register (PDTCTL) configures the latency of the APDT signal with respect to
the data phase of a read transaction. The latency of the APDT signal for a read can be programmed to 0, 1, 2, or 3 by setting PDTRL to 00, 01,
10, or 11, respectively. PDTRL equals 00 (zero latency) in this figure.

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 5-32.
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.

5.9
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).
5.9.1
McASP0 Device-Specific Information
The TMS320DM643 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).
5.9.1.1
McASP Block Diagram
Figure 5-34 illustrates the major blocks along with external signals of the TMS320DM643 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.

The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus™ system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then
be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH) = 1000 + 250 = 1250 ns
(according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

Host-Port Interface (HPI)
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 a word transfer (HPI32) or 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.

Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
• Full-duplex communication
• 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
On the DM643 device, the McBSP peripheral does not support external clocking to the sample rate
generator (no CLKS input).
For more detailed information on the McBSP peripheral, see the TMS320C6000 DSP Multichannel
Buffered Serial Port (McBSP) Reference Guide (literature number SPRU580).

P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
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.

L = CLKX low pulse width = (CLKGDV + 1)/2 * 4P if CLKGDV is odd or zero
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see footnote (4) above).
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.

SPRS269B – FEBRUARY 2005 – REVISED OCTOBER 2005
5.13
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 BT.656 and
SMPTE296.
5.13.1
Video Port Device-Specific Information
The TMS320DM643 device has two video port peripherals.
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 two channels: A and B. A 5120-byte capture/display buffer is splittable between the
two channels. The entire port (both channels) 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, Y/C, raw video, and TSI modes.
For video capture operation, the video port may operate as two 8/10-bit channels of BT.656 or raw video
capture; or as a single channel of 8/10-bit BT.656, 8/10-bit raw video, 16/20-bit Y/C video, 16/20-bit raw
video, or 8-bit TSI.
For video display operation, the video port may operate as a single channel of 8/10-bit BT.656; or as a
single channel of 8/10-bit BT.656, 8/10-bit raw video, 16/20 bit Y/C video, or 16/20-bit raw video. It may
also operate in a two channel 8/10-bit raw mode in which the two channels are locked to the same timing.
Channel B is not used during single channel operation.
For more detailed information on the DM643 Video Port peripherals, see the TMS320C64x DSP Video
Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number SPRU629).

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.
5.14.1
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, 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 DM643 VCXO interpolated control (VIC) peripheral, see the
TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number
SPRU629).

Ethernet Media Access Controller (EMAC)
The EMAC controls the flow of packet data from the DSP to the PHY.
5.15.1
EMAC Device-Specific Information
The ethernet media access controller (EMAC) provides an efficient interface between the DM643 DSP
core processor and the network. The DM643 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 DM643 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.
The TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output
(MDIO) Module Reference Guide (literature number SPRU628) describes the DM643 EMAC peripheral in
detail. Some of the features documented in this peripheral reference guide are not supported on the
DM643 at this time. The DM643 supports one receive channel and does not support receive quality of
service (QOS). For a list of supported registers and register fields, see Table 5-60 [Ethernet MAC (EMAC)
Control Registers] and Table 5-61 [EMAC Statistics Registers] in this data manual.

Management Data Input/Output (MDIO)
The MDIO module controls PHY configuration and status monitoring.
5.16.1
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.
The TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output
(MDIO) Module Reference Guide (literature number SPRU628) describes the DM643 MDIO peripheral in
detail. Some of the features documented in this peripheral reference guide are not supported on the
DM643 at this time. The DM643 only supports one EMAC module. For a list of supported registers and
register fields, see Table 5-68 [MDIO Registers] in this data manual.

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.
5.17.1
Timer Device-Specific Information
The DM643 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)
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.
5.18.1
GPIO Device-Specific Information
To use the GP[15:0] 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 = 1
GP[x] pin is enabled
GPxDIR = 0
GP[x] pin is an input
GPxDIR = 1
GP[x] pin is an output
where "x" represents one of the 15 through 0 GPIO pins
Figure 5-66 shows the GPIO enable bits in the GPEN register for the DM643 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 5-66 for the DM643 default configuration.

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.

JTAG
The JTAG interface is used for BSDL testing and emulation of the DM643 device.
Note: IEEE Standard 1149.1-1990 Standard-Test-Access Port and Boundary Scan Architecture.
5.19.1
JTAG Device-Specific Information
5.19.1.1
IEEE 1149.1 JTAG Compatibility Statement
The TMS320DM643 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 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.
The TMS320DM643 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 when this pin is not routed out. 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 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.
Note: The DESIGN_WARNING section of the TMS320DM643 BSDL file contains information and
constraints regarding proper device operation while in Boundary Scan Mode.
