description
The TMS320C67xt DSPs (including the TMS320C6713 device†) compose the floating-point DSP generation
in the TMS320C6000t DSP platform. The C6713 device is based on the high-performance, advanced
very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an
excellent choice for multichannel and multifunction applications.
Operating at 225 MHz, the C6713 delivers up to 1350 million floating-point operations per second (MFLOPS),
1800 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to 450 million
multiply-accumulate operations per second (MMACS).
The C6713 uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The
Level 1 program cache (L1P) is a 4K-Byte direct-mapped cache and the Level 1 data cache (L1D) is a 4K-Byte
2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 256K-Byte memory space that is
shared between program and data space. 64K Bytes of the 256K Bytes in L2 memory can be configured as
mapped memory, cache, or combinations of the two. The remaining 192K Bytes in L2 serves as mapped SRAM.
The C6713 has a rich peripheral set that includes two Multichannel Audio Serial Ports (McASPs), two
Multichannel Buffered Serial Ports (McBSPs), two Inter-Integrated Circuit (I2C) buses, one dedicated
General-Purpose Input/Output (GPIO) module, two general-purpose timers, a host-port interface (HPI), and a
glueless external memory interface (EMIF) capable of interfacing to SDRAM, SBSRAM, and asynchronous
peripherals.
The two McASP interface modules each support one transmit and one receive clock zone. Each of the McASP
has 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 C6713 has sufficient bandwidth to support
all 16 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 McASP 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.
The McASP 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 two I2C ports on the TMS320C6713 allow 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 TMS320C6713 device has two bootmodes: from the HPI or from external asynchronous ROM. For more
detailed information, see the bootmode section of this data sheet.
The TMS320C67x DSP generation is supported by the TI eXpressDSPt set of industry benchmark
development tools, including a highly optimizing C/C++ Compiler, the Code Composer Studiot Integrated
Development Environment (IDE), JTAG-based emulation and real-time debugging, and the DSP/BIOSt
kernel.
TMS320C6000, eXpressDSP, Code Composer Studio, and DSP/BIOS are trademarks of Texas Instruments.
†Throughout the remainder of this document, the TMS320C6713 shall be referred to as C6713 or 13.

CPU (DSP core) description
The TMS320C6713 floating-point digital signal processor is based on the C67x CPU. The CPU fetches
advanced very-long instruction words (VLIW) (256 bits wide) to supply up to eight 32-bit instructions to the eight
functional units during every clock cycle. The VLIW architecture features controls by which all eight units do no t
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 C67x CPU from other VLIW architectures.
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 16 32-bit registers for a total of 32 general-purpose registers. 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 diagram and
Figure 1). The four functional units on each side of the CPU can freely share the 16 registers belonging to that
side. Additionally, each side features 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. While 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,
register access using the register file across the CPU supports one read and one write per cycle.
The C67x CPU executes all C62x instructions. In addition to C62x fixed-point instructions, the six out of eight
functional units (.L1, .S1, .M1, .M2, .S2, and .L2) also execute floating-point instructions. The remaining two
functional units (.D1 and .D2) also execute the new LDDW instruction which loads 64 bits per CPU side for a
total of 128 bits per cycle.
Another key feature of the C67x 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
C67x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing modes
with 5- o r 15-bit of fsets. All instructions are conditional, and most can access any one of the 32 registers. Some
registers, however, are singled out to support specific addressing or to hold the condition for conditional
instructions (if the condition is not automatically “true”). The two .M functional units are dedicated for multiplies.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle.
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. 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. 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 or half-words as well. All load and store
instructions are byte-, half-word, or word-addressable.

DEVICE CONFIGURATIONS
On the C6713 device, bootmode and certain device configurations/peripheral selections are determined at
device reset, while other device configurations/peripheral selections are software-configurable via the device
configurations register (DEVCFG) [address location 0x019C0200] after device reset.
device configurations at device reset
Table 18 describes the C6713 device configuration pins, which are set up via internal or external
pullup/pulldown resistors through the HPI data pins (HD[4:3], HD8), and CLKMODE0 pin. These configuration
pins must be in the desired state until reset is released.
For proper device operation of the C6713 device, do not oppose the HD [15, 13:9, 7, 1, 0] pins with the external
pullups/pulldowns at reset.
For more details on these device configuration pins, see the Terminal Functions table and the Debugging
Considerations section of this data sheet.

DEVICE CONFIGURATIONS (CONTINUED)
multiplexed pins
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Most of
these pins are configured by software via the device configuration register (DEVCFG), and the others
(specifically, the HPI pins) are configured by external pullup/pulldown resistors only at reset. The muxed pins
that are configured by software can be programmed to switch functionalities at any time. The 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 22 summarizes the peripheral pins affected by the HPI_EN
(HD14 pin) and DEVCFG register. Table 23 identifies the multiplexed pins on the C6713 device; shows the
default (primary) function and the default settings after reset; and describes the pins, registers, etc. necessary
to configure the specific multiplexed functions.

debugging considerations
It is recommended that external connections be provided to peripheral selection/device configuration pins,
including HD[14, 8, 4, 3], and CLKMODE0. Although internal pullup 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 HPI data bus (HD[15, 13:9,
7:5, 2:0]. For proper device operation of the HD[15, 13:9, 7, 1, 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 HD[15, 13:9, 7, 1, 0] non-configuration pins, these signals must be driven to the default
state of the pins at reset, or not be driven at all. For a list of routed out, 3-stated, or not-driven pins recommended
for external pullup/pulldown resistors, and internal pullup/pulldown resistors for all device pins, etc., see the
Terminal Functions table. However, the HD[6, 5, 2] non-configuration pins can be opposed and driven during
reset.

The DSP can be placed in Functional mode when the EMU[1:0] pins are
configured for either Boundary Scan or Emulation.
Note: When the EMU[1:0] pins are configured for Boundary Scan mode, the
internal pulldown (IPD) on the TRST signal must not be opposed in order to
operate in Functional mode.
For the Boundary Scan mode drive EMU[1:0] and RESET pins low.

‡IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors
no greater than 4.4 kΩ and 2.0 kΩ, respectively.]
§To ensure a proper logic level during reset when these pins are both routed out and 3−stated or not driven, it is recommended to include an
external 10 kΩ pullup/pulldown resistor to sustain the IPU/IPD, respectively.

device support
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., TMS320C6713GDP225). Texas Instruments recommends two of three possible prefix designators for
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 with 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, GDP), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -225 is 225 MHz).
For device part numbers and further ordering information for TMS320C6713 in the PYP and GDP, package
types, see the TI website (http://www.ti.com) or contact your TI sales representative.

interrupts and interrupt selector
The C67x DSP core supports 16 prioritized interrupts, which are listed in Table 25. The highest priority interrupt
is INT_00 (dedicated to RESET) while the lowest priority is INT_15. The first four interrupts are non-maskable
and fixed. The remaining interrupts (4−15) are maskable and default to the interrupt source listed in Table 25.
However, their interrupt source may be reprogrammed to any one of the sources listed in Table 26 (Interrupt
Selector). Table 26 lists the selector value corresponding to each of the alternate interrupt sources. The selector
choice for interrupts 4−15 is made by programming the corresponding fields (listed in Table 25) in the MUXH
(address 0x019C0000) and MUXL (address 0x019C0004) registers.

†Interrupt Events GPINT4, GPINT5, GPINT6, and GPINT7 are outputs from the GPIO module (GP). They originate from the device pins
GP[4](EXT_INT4)/AMUTEIN1, GP[5](EXT_INT5)/AMUTEIN0, GP[6](EXT_INT6), and GP[7](EXT_INT7). These pins can be used as
edge-sensitive EXT_INTx with polarity controlled by the External Interrupt Polarity Register (EXTPOL.[3:0]). The corresponding pins must
first b e enabled in the GPIO module by setting the corresponding enable bits in the GP Enable Register (GPEN.[7:4]), and configuring them
as inputs in the GP Direction Register (GPDIR.[7:4]). These interrupts can be controlled through the GPIO module in addition to the simple
EXTPOL.[3:0] bits. For more information on interrupt control via the GPIO module, see the TMS320C6000 DSP General-Purpose
Input/Output (GPIO) Reference Guide (literature number SPRU584).

external interrupt sources
The C6713 device supports many external interrupt sources as indicated in Table 27. Control of the interrupt
source is done by the associated module and is made available by enabling the corresponding binary interrupt
selector value (see Table 26 Interrupt Selector shaded rows). Due to pin muxing and module usage, not all
external interrupt sources are available at the same time.

EDMA module and EDMA selector
The C67x EDMA supports up to 16 EDMA channels. Four of the sixteen channels (channels 8−11) are reserved
for EDMA chaining, leaving 12 EDMA channels available to service peripheral devices.
The EDMA selector registers that control the EDMA channels servicing peripheral devices are located at
addresses 0x01A0FF00 (ESEL0), 0x01A0FF04 (ESEL1), and 0x01A0FF0C (ESEL3). These EDMA selector
registers control the mapping of the EDMA events to the EDMA channels. Each EDMA event has an assigned
EDMA selector code (see Table 29). By loading each EVTSELx register field with an EDMA selector code, users
can map any desired EDMA event to any specified EDMA channel. Table 28 lists the default EDMA selector
value for each EDMA channel.
See Table 30 and Table 31 for the EDMA Event Selector registers and their associated bit descriptions.

EVTSELx
EDMA event selection bits for channel x. Allows mapping of the EDMA events to the EDMA channels.
The EVTSEL0 through EVTSEL15 bits correspond to the channels 0 to 15, respectively. These
EVTSELx fields are user−selectable. By configuring the EVTSELx fields to the EDMA selector value
of the desired EDMA sync event number (see Table 29), users can map any EDMA event to the
EDMA channel.
For example, if EVTSEL15 is programmed to 00 0001b (the EDMA selector code for TINT0), then
channel 15 is triggered by Timer0 TINT0 events.

PLL and PLL controller
The TMS320C6713 includes a PLL and a flexible PLL Controller peripheral consisting of a prescaler (D0) and
four dividers (OSCDIV1, D1, D2, and D3). The PLL controller is able to generate different clocks for different
parts of the system (i.e., DSP core, Peripheral Data Bus, External Memory Interface, McASP, and other
peripherals). Figure 14 illustrates the PLL, the PLL controller, and the clock generator logic.

NOTES: A. Place all PLL external components (C1, C2, and the EMI Filter) as close to the C67x 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, DVDD.

The PLL Reset Time is the amount of wait time needed when resetting the PLL (writing PLLRST=1), in order
for the PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the PLL Reset Time
value, see Table 32. The PLL Lock Time is the amount of time from when PLLRST = 0 with PLLEN = 0 (PLL
out of reset, but still bypassed) to when the PLLEN bit can be safely changed to “1” (switching from bypass to
the PLL path), see Table 32 and Figure 14.
Under some operating conditions, the maximum PLL Lock Time may vary from the specified typical value. For
the PLL Lock Time values, see Table 32.

SYSCLK3 selected [default].
To select ECLKIN source:
EKSRC = 1 (DEVCFG.[4]) and
EKEN = 1 (EMIF GBLCTL.[5])
The input clock (CLKIN) is directly available to the McASP modules as AUXCLK for use as an internal
high-frequency clock source. The input clock (CLKIN) may also be divided down by a programmable divider
OSCDIV1 (/1, /2, /3, ..., /32) and output on the CLKOUT3 pin for other use in the system.
Figure 14 shows that the input clock source may be divided down by divider PLLDIV0 (/1, /2, ..., /32) and then
multiplied up by a factor of x4, x5, x6, and so on, up to x25.
Either the input clock (PLLEN = 0) or the PLL output (PLLEN = 1) then serves as the high-frequency reference
clock for the rest of the DSP system. The DSP core clock, the peripheral bus clock, and the EMIF clock may
be divided down from this high-frequency clock (each with a unique divider) . For example, with a 30 MHz input
if the PLL output is configured for 450 MHz, the DSP core may be operated at 225 MHz (/2) while the EMIF may
be configured to operate at a rate of 75 MHz (/6). Note that there is a specific minimum and maximum reference
clock (PLLREF) and output clock (PLLOUT) for the block labeled PLL in Figure 14, as well as for the DSP core,
peripheral bus, and EMIF. The clock generator must not be configured to exceed any of these constraints
(certain combinations of external clock input, internal dividers, and PLL multiply ratios might not be supported).
See Table 34 for the PLL clocks input and output frequency ranges.

AUXCLK − 50§MHz
†SYSCLK2 rate must be exactly half of SYSCLK1.
‡Also see the electrical specification (timing requirements and switching characteristics parameters) in the input and output clocks section of this
data sheet.
§When the McASP module is not used, the AUXCLK maximum frequency can be any frequency up to the CLKIN maximum frequency.
The EMIF itself may be clocked by an external reference clock via the ECLKIN pin or can be generated on-chip
as SYSCLK3. SYSCLK3 is derived from divider D3 off of PLLOUT (see Figure 14, PLL and Clock Generator
Logic). The EMIF clock selection is programmable via the EKSRC bit in the DEVCFG register.
The settings for the PLL multiplier and each of the dividers in the clock generation block may be reconfigured
via software at run time. If either the input to the PLL changes due to D0, CLKMODE0, or CLKIN, or if the PLL
multiplier is changed, then software must enter bypass first and stay in bypass until the PLL has had enough
time to lock (see electrical specifications). For the programming procedure, see the TMS320C6000 DSP
Software-Programmable Phase-Locked Loop (PLL) Controller Reference Guide (literature number SPRU233).
SYSCLK2 is the internal clock source for peripheral bus control. SYSCLK2 (Divider D2) must be programmed
to be half of the SYSCLK1 rate. For example, if D1 is configured to divide-by-2 mode (/2), then D2 must be
programmed to divide-by-4 mode (/4). SYSCLK2 is also tied directly to CLKOUT2 pin (see Figure 14).
During the programming transition of Divider D1 and Divider D2 (resulting in SYSCLK1 and SYSCLK2 output
clocks, see Figure 14), the order of programming the PLLDIV1 and PLLDIV2 registers must be observed to
ensure that SYSCLK2 always runs at half the SYSCLK1 rate or slower. For example, if the divider ratios of D1
and D2 are to be changed from /1, /2 (respectively) to /5, /10 (respectively) then, the PLLDIV2 register must be
programmed before the PLLDIV1 register. The transition ratios become /1, /2; /1, /10; and then /5, /10. If the
divider ratios of D1 and D2 are to be changed from /3, /6 to /1, /2 then, the PLLDIV1 register must be programmed
before the PLLDIV2 register. The transition ratios, for this case, become /3, /6; /1, /6; and then /1, /2. The final
SYSCLK2 rate must be exactly half of the SYSCLK1 rate.
Note that Divider D1 and Divider D2 must always be enabled (i. e., D1EN and D2EN bits are set to “1” in the
PLLDIV1 and PLLDIV2 registers).
The PLL Controller registers should be modified only by the CPU or via emulation. The HPI should not be used
to directly access the PLL Controller registers.
For detailed information on the clock generator (PLL Controller registers) and their associated software bit
descriptions, see Table 36 through Table 42.

multichannel audio serial port (McASP) peripherals
The TMS320C6713 device includes two multi-channel audio serial port (McASP) interface peripherals
(McASP1 and McASP0). The McASP is a serial port optimized for the needs of multi-channel audio applications.
With two McASP peripherals, the TMS320C6713 device is capable of supporting two completely independent
audio zones simultaneously.
Each McASP consists of a transmit and receive section. These sections can operate completely independently
with di fferent data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit and
receive sections may be synchronized. Each 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.
Each 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 peripherals have additional capability for flexible clock generation, and error detection/handling,
as well as error management.
McASP block diagram
Figure 15 illustrates the major blocks along with external signals of the TMS320C6713 McASP1 and McASP0
peripherals; and shows the 8 serial data [AXR] pins for each McASP. Each 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.

multichannel audio serial port (McASP) peripherals (continued)
multichannel time division multiplexed (TDM) synchronous transfer mode
The McASP supports a multichannel, time-division-multiplexed (TDM) synchronous transfer mode for both
transmit and receive. Within this transfer mode, a wide variety of serial data formats are supported, including
formats compatible with devices using the Inter-Integrated Sound (IIS) protocol.
TDM synchronous transfer mode is typically used when communicating between integrated circuits such as
between a DSP and one or more ADC, DAC, CODEC, or S/PDIF receiver devices. In multichannel applications,
it is typical to find several devices operating synchronized with each other. For example, to provide six analog
outputs, three stereo DAC devices would be driven with the same bit clock and frame sync, but each stereo DAC
would use a different McASP serial data pin carrying stereo data (2 TDM time slots, left and right).
The TDM synchronous serial transfer mode utilizes several control signals and one or more serial data signals:
DA bit clock signal (ACLKX for transmit, ACKLR for receive)
DA frame sync signal (AFSX for transmit, AFSR for receive)
DAn (Optional) high frequency master clock (AHCLKX for transmit, AHCLKR for receive) from which the bit
clock is derived
DOne or more serial data pins (AXR for transmit and for receive).
Except for the optional high-frequency master clock, all of the signals in the TDM synchronous serial transfer
mode protocol are synchronous to the bit clocks (ACLKX and ACLKR).
In the TDM synchronous transfer mode, the McASP continually transmits and receives data periodically (since
audio ADCs and DACs operate at a fixed-data rate). The data is organized into frames, and the beginning of
a frame is marked by a frame sync pulse on the AFSX, AFSR pin.
In a typical audio system, one frame is transferred per sample period. To support multiple channels, the choices
are to either include more time slots per frame (and therefore operate with a higher bit clock) or to keep the bit
clock period constant and use additional data pins to transfer the same number of channels. For example, a
particular six-channel DAC might require three McASP serial data pins; transferring two channels of data on
each serial data pin during each sample period (frame). Another similar DAC may be designed to use only a
single McASP serial data pin, but clocked three times faster and transferring six channels of data per sample
period. The McASP is flexible enough to support either type of DAC but a transmitter cannot be configured to
do both at the same time.
For multiprocessor applications, the McASP supports any number of time slots per frame (between 2 and 32),
and includes the ability to “disable” transfers during specific time slots.
In addition, to support of S/PDIF, AES-3, IEC-60958, CP-430 receivers chips whose natural block (McASP
frame) size is 384 samples; the McASP receiver supports a 384 time slot mode. The advantage to using the
384 time slot mode is that interrupts may be generated synchronous to the S/PDIF, AES-3, IEC-60958, CP-430
receivers, for example the “last slot” interrupt.
burst transfer mode
The McASP also supports a burst transfer mode, which is useful for non-audio data (for example, passing
control information between two DSPs). Burst transfer mode uses a synchronous serial format similar to TDM,
except the frame sync is generated for each data word transferred. In addition, frame sync generation is not
periodic or time-driven as in TDM mode but rather data-driven.

multichannel audio serial port (McASP) peripherals (continued)
supported bit stream formats for TDM and burst transfer modes
The serial data pins support a wide variety of formats. In the TDM and burst synchronous modes, the data may
be transmitted / received with the following options:
DTime slots per frame: 1 (Burst/Data Driven), or 2,3...32 (TDM/Time-Driven).
DTime slot size: 8, 12, 16, 20, 24, 28, 32 bits per time slot
DData size: 8, 12, 16, 20, 24, 28, 32 bits (must be less than or equal to time slot)
DData alignment within time slot: Left- or Right-Justified
DBit order: MSB or LSB first.
DUnused bits in time slot: Padded with 0, 1 or extended with value of another bit.
DTime slot delay from frame sync: 0,1, or 2 bit delay
The data format can be programmed independently for transmit and receive, and for McASP0 vs. McASP1. In
addition, the McASP can automatically re-align the data as processed natively by the DSP (any format on a
nibble boundary) adjusting the data in hardware to any of the supported serial bit stream formats (TDM, Burst,
and DIT modes). This reduces the amount of bit manipulation that the DSP must perform and simplifies software
architecture.
digital audio interface transmitter (DIT) transfer mode (transmitter only)
The McASP transmit section may also be configured in digital audio interface transmitter (DIT) mode where it
outputs data formatted for transmission over an S/PDIF, AES-3, IEC-60958, or CP-430 standard link. These
standards encode the serial data such that the equivalent of ’clock’ and ’frame sync’ are embedded within the
data stream. DIT transfer mode is used as an interconnect between audio components and can transfer
multichannel digital audio data over a single optical or coaxial cable.
From an internal DSP standpoint, the McASP operation in DIT transfer mode is similar to the two time slot TDM
mode, but the data transmitted is output as a bi-phase mark encoded bit stream with preamble, channel status,
user data, validity, and parity automatically stuffed into the bit stream by the McASP module. The McASP
includes separate validity bits for even/odd subframes and two 384-bit register file modules to hold channel
status and user data bits.
DIT mode requires at minimum:
DOne serial data pin (if the AUXCLK is used as the reference [see the PLL and Clock Generator Logic
Figure 14]) or
DOne serial data pin plus either the AHCLKX or ACLKX pin (if an external clock is needed).
If additional serial data pins are used, each McASP may be used to transmit multiple encoded bit streams (one
per pin). However, the bit streams will all b e synchronized to the same clock and the user data, channel status,
and validity information carried by each bit stream will be the same for all bit streams transmitted by the same
McASP module.
The McASP can also automatically re-align the data as processed by the DSP (any format on a nibble boundary)
in DIT mode; reducing the amount of bit manipulation that the DSP must perform and simplifies software
architecture.

multichannel audio serial port (McASP) peripherals (continued)
McASP flexible clock generators
The McASP transmit and receive clock generators are identical. Each clock generator can accept a
high-frequency master clock input (on the AHCLKX and AHCLKR pins).
The transmit and receive bit clocks (on the ACLKX and ACLKR pins) can also be sourced externally or can be
sourced internally by dividing down the high-frequency master clock input (programmable factor /1, /2, /3, ...
/4096). The polarity of each bit clock is individually programmable.
The frame sync pins are AFSX (transmit) and AFSR (receive). A typical usage for these pins is to carry the
left-right clock (LRCLK) signal when transmitting and receiving stereo data. The frame sync signals are
individually programmable for either internal or external generation, either bit or slot length, and either rising or
falling edge polarity.
Some examples of the things that a system designer can use the McASP clocking flexibility for are:
DInput a high-frequency master clock (for example, 512fs of the receiver), receive with an internally
generated bit clock ratio of /8, while transmitting with an internally generated bit clock ratio of /4 or /2. [An
example application would be to receive data from a DVD at 48 kHz but output up-sampled or decoded
audio at 96 kHz or 192 kHz.]
DTransmit/receive data based one sample rate (for example, 44.1 kHz) using McASP0 while transmitting and
receiving at a different sample rate (for example, 48 kHz) on McASP1.
DUse the DSP’s on-board AUXCLK to supply the system clock when the input source is an A/D converter.
McASP error handling and management
To support the design of a robust audio system, the McASP module includes error-checking capability for the
serial protocol, data underrun, and data overrun. In addition, each McASP includes a timer that continually
measures the high-frequency master clock every 32-SYSCLK2 clock cycles. The timer value can be read to
get a measurement of the high-frequency master clock frequency and has a min-max range setting that can
raise an error flag if the high-frequency master clock goes out of a specified range. The user would read the
high-frequency transmit master clock measurement (AHCLKX0 or AHCLKX1) by reading the XCNT field of the
XCLKCHK register and the user would read the high-frequency receive master clock measurement (AHCLKR0
or AHCLKR1) by reading the RCNT field of the RCLKCHK register.
Upon the detection of any one or more of the above errors (software selectable), or the assertion of the
AMUTE_IN pin, the AMUTE output pin may be asserted to a high or low level (selectable) to immediately mute
the audio output. In addition, an interrupt may be generated if enabled based on any one or more of the error
sources.
McASP interrupts and EDMA events
The McASP transmitter and receiver sections each generate an event on every time slot. This event can be
serviced by an interrupt or by the EDMA controller.
When using interrupts to service the McASP, each shift register buffer has a unique address in the McASP
Registers space (see Table 3).
When using the EDMA to service the McASP, the McASP DATA Port space in Table 3 is accessed. In this case,
the address least-significant bits are ignored. Writes to any address in this range access the transmitting buffers
in order from lowest (serializer 0) to highest (serializer 15), skipping over disabled and receiving serializers.
Likewise, reads from any address in this space access the receiving buffers in the same order but skip over
disabled and transmitting buffers.

I2C
Having two I2C modules on the TMS320C6713 simplifies system architecture, since one module may be used

with other controllers in a system or to implement a user interface.
The TMS320C6713 also includes two I2C serial ports for control purposes. Each I2C port supports:

†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.
On C6713, the device includes a programmable PLL which allows software control of PLL bypass via the PLLEN
bit in the PLLCSR register. With this enhanced functionality comes some additional considerations when
entering power-down modes.
The power-down modes (PD2 and PD3) function by disabling the PLL to stop clocks to the device. However,
if the PLL is bypassed (PLLEN = 0), the device will still receive clocks from the external clock input (CLKIN).
Therefore, bypassing the PLL makes the power-down modes PD2 and PD3 ineffective.
Make sure that the PLL is enabled by writing a “1” to PLLEN bit (PLLCSR.0) before writing to either PD3
(CSR.11) or PD2 (CSR.10) to enter a power-down mode.
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

system-level design considerations
System-level design considerations, such as bus contention, may require supply sequencing to be
implemented. In this case, the core supply should be powered up prior to (and powered down after), the I/O
buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the output buffers are
powered up, thus, preventing bus contention with other chips on the board.

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 21).

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.
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 (no more than 1.25 cm maximum distance) to the DSP
to be effective. Physically smaller caps are better, such as 0402, but the size needs to be evaluated from a
yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling capacitors,
therefore physically smaller capacitors should be used while maintaining the largest available capacitance
value. As with the selection of any component, verification of capacitor availability over the product’ s production
lifetime needs to be considered.

IEEE 1149.1 JTAG compatibility statement
The TMS320C6713 DSP requires that both TRST and RESET resets 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.
The TMS320C6713 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 J TAG controllers may not drive TRST high but expect the use of an external pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize 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 TMS320C6713 BSDL file contains information and constraints regarding proper device operation
while in Boundary Scan Mode. For more detailed information on the C6713 JTAG emulation, see the
TMS320C6000 DSP Designing for JTAG Emulation Reference Guide (literature number SPRU641).
EMIF device speed
The maximum EMIF speed on the C6713 device is 100 MHz. TI recommends utilizing I/O buffer information
specification (IBIS) to analyze all AC timings to determine if the maximum EMIF speed is achievable for a given
board layout. 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).
For ease of design evaluation, Table 44 contains IBIS simulation results showing the maximum EMIF-SDRAM
interface speeds for the given example boards (TYPE) and SDRAM speed grades. Timing analysis should be
performed to verify that all AC timings are met for the specified board layout. Other configurations are also
possible, but again, timing analysis must be done to verify proper AC timings.
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).

bootmode
The C6713 device resets using the active-low signal RESET and the internal reset signal. While RESET is low,
the internal reset is also asserted and 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 the
internal reset signal (see the Reset Phase 3 discussion in the Reset Timing section of this data sheet) starts
the processor running with the prescribed device configuration and boot mode.
The C6713 has three types of boot modes:
DHost boot
If host boot is selected, upon release of internal 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 i s 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.
DEmulation boot
Emulation boot mode is a variation of host boot. In this mode, it is not necessary for a host to load code or to
set DSPINT to release the CPU from the “stalled” state. Instead, the emulator will set DSPINT if it has not
been previously set so that the CPU can begin executing code from address 0. Prior to beginning execution,
the emulator sets a breakpoint at address 0. This prevents the execution of invalid code by halting the CPU
prior to executing the first instruction. Emulation boot is a good tool in the debug phase of development.
DEMIF boot (using default ROM timings)
Upon the release of internal reset, the 1K-Byte ROM code located in the beginning of CE1 is copied to
address 0 b y 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. The boot process also lets you choose the width of
the ROM. In this case, the EMIF automatically assembles consecutive 8-bit bytes or 16-bit half-words 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 start running from address 0.
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.

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 45 and Figure 27).
Figure 27 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.

Note that while internal reset is asserted low, the CPU clock (SYSCLK1) period is equal to the input clock (CLKIN) period multiplied by 8. For
example, if the CLKIN period is 20 ns, then the CPU clock (SYSCLK1) period is 20 ns x 8 = 160 ns. Therefore, P = SYSCLK1 = 160 ns while
internal reset is asserted.

Figure 46. Reset Timing
Reset Phase 1: The RESET pin is asserted. During this time, all internal clocks are running at the CLKIN
frequency divide-by-8. The CPU is also running at the CLKIN frequency divide-by-8.
Reset Phase 2: The RESET pin is deasserted but the internal reset is stretched. During this time, all internal
clocks are running at the CLKIN frequency divide-by-8. The CPU is also running at the CLKIN frequency
divide-by-8.
Reset Phase 3: Both the RESET pin and internal reset are deasserted. During this time, all internal clocks are
running at their default divide-down frequency of CLKIN. The CPU clock (SYSCLK1) is running at CLKIN
frequency. The peripheral clock (SYSCLK2) is running at CLKIN frequency divide-by-2. The EMIF internal clock
source (SYSCLK3) is running at CLKIN frequency divide-by-2. SYSCLK3 is reflected on the ECLKOUT pin
(when EKSRC bit = 0 [default]). CLKOUT3 is running at CLKIN frequency divide-by-8.

†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.

‡P = 1/CPU clock frequency in ns. For example, when running parts at 225 MHz, use P = 4.4 ns.
¶HCS enables HRDY, and HRDY is always low when HCS is high. The case where HRDY goes high when HCS falls indicates that HPI is busy
completing a previous HPID write or READ with autoincrement.
#This parameter is used during an HPID read. At the beginning of the first half-word transfer 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.
|| This parameter is used after the second half-word of an HPID write or autoincrement read. HRDY remains low if the access is not an HPID write
or autoincrement read. Reading or writing to HPIC or HPIA does not affect the HRDY signal.

†CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
‡P = 1/CPU clock frequency in ns. For example, when running parts at 225 MHz, use P = 4.4 ns.
§The minimum CLKR/X period is twice the CPU cycle time (2P) and not faster than 75 Mbps (13.3 ns). This means that the maximum bit rate for
communications between the McBSP and other devices is 75 Mbps for 167-MHz and 225-MHz CPU clocks or 50 Mbps for 100-MHz CPU clock;
where the McBSP is either the master or the slave. Care must be taken to ensure that the AC timings specified in this data sheet are met. The
maximum bit rate for McBSP-to-McBSP communications is 67 Mbps; therefore, the minimum CLKR/X clock cycle is either twice the CPU cycle
time (2P), or 15 ns (67 MHz), whichever value is larger. For example, when running parts at 150 MHz (P = 6.7 ns), use 15 ns as the minimum
CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running parts at 60 MHz (P = 16.67 ns), use 2P =
33 ns (30 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP communications applies when the serial port
is a master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM
= 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP communicates to is a slave.
¶This parameter applies to the maximum McBSP frequency. Operate serial clocks (CLKR/X) in the resonable range of 40/60 duty cycle.

†CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
‡Minimum delay times also represent minimum output hold times.
§P = 1/CPU clock frequency in ns. For example, when running parts at 225 MHz, use P = 4.4 ns.
¶The minimum CLKR/X period is twice the CPU cycle time (2P) and not faster than 75 Mbps (13.3 ns). This means that the maximum bit rate for
communications between the McBSP and other devices is 75 Mbps for 167-MHz and 225-MHz CPU clocks or 50 Mbps for 100-MHz CPU clock;
where the McBSP is either the master or the slave. Care must be taken to ensure that the AC timings specified in this data sheet are met. The
maximum bit rate for McBSP-to-McBSP communications is 67 Mbps; therefore, the minimum CLKR/X clock cycle is either twice the CPU cycle
time (2P), or 15 ns (67 MHz), whichever value is larger. For example, when running parts at 150 MHz (P = 6.7 ns), use 15 ns as the minimum
CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running parts at 60 MHz (P = 16.67 ns), use 2P =
33 ns (30 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP communications applies when the serial port
is a master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM
= 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP communicates to is a slave.
#C = H or L
S = sample rate generator input clock = 2P if CLKSM = 1 (P = 1/CPU clock frequency)
= 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
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S 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 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.
If DXENA = 0, then D1 = D2 = 0
If DXENA = 1, then D1 = 2P, D2 = 4P
