3.1 Description
The TMS320C67x™ DSPs (including the SM320C6713 and SM320C6713B devices) compose the
floating-point DSP generation in the TMS320C6000™ DSP platform. The C6713 and C6713B devices are
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. Throughout the remainder of this document, the SM320C6713 and SM320C6713B are
referred to as 320C67x or C67x or 13/13B where generic, and where specific, their individual full device
part numbers are used or abbreviated as C6713, C6713B, 13, or 13B, and so forth.
Operating at 225 MHz, the C6713/13B 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).
Operating at 300 MHz, the C6713B delivers up to 1800 million floating-point operations per second
(MFLOPS), 2400 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to
600 million multiply-accumulate operations per second (MMACS).

The C6713/13B 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
McASPs has eight serial data pins that 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 C6713/13B 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, and
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 320C6713/13B 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 320C6713/13B device has two boot modes—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 eXpressDSP™ set of industry benchmark
development tools, including a highly optimizing C/C++ Compiler, the Code Composer Studio™ Integrated
Development Environment (IDE), JTAG-based emulation and real-time debugging, and the DSP/BIOS™
kernel.

OVERVIEW
4.1 CPU (DSP Core) Description
The 320C6713/13B 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 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 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 (DSP Core) Diagram and Figure 4-1). 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- or 15-bit offsets. 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 chained 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 C6713/13B devices, 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.
5.1 Device Configurations at Device Reset
Table 5-1 describes the C6713 and C6713B device configuration pins, which are set up via internal or
external pullup/pulldown resistors through the HPI data pins (HD[4:3], HD8, HD12 [13B only]), and
CLKMODE0 pin. These configuration pins must be in the desired state until reset is released. For proper
device operation, do not oppose the HD [13, 11:9, 7, 1, 0] pins with 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.

FUNCTIONAL DESCRIPTION
PIN
EMIF Big Endian mode correctness (EMIFBE) [C6713B only]
For a C6713BGDP:
0 – The EMIF data will always be presented on the ED[7:0] side of the bus, regardless of the
endianess mode (Little/Big Endian).
1 –
In Little Endian mode (HD8 = 1), the 8-bit or 16-bit EMIF data will be present on the
ED[7:0] side of the bus.
In Big Endian mode (HD8 = 0), the 8-bit or 16-bit EMIF data will be present on the
ED[31:24] side of the bus [default].
HD12(2)
C15
For a C6713BPYP, when Big Endian mode is selected (LENDIAN = 0), for proper device operation the
EMIFBE pin must be externally pulled low.
This enhancement is not supported on the C6713 device.
For proper C6713 device operation, do not oppose the internal pullup (IPU) resistor on this pin.
This new functionality does not affect systems using the current default value of HD12 = 1. For more
detailed information on the big endian mode correctness, see the EMIF Big Endian Mode Correctness
[C6713B only] portion of this data sheet.

This pin must be pulled to the correct level even after reset.
(1) All other HD pins [HD [15, 13:9, 7:5, 2:0] (for 13) or HD [15, 13, 11:9, 7:5, 2:0] (for 13B)] have pullups/pulldowns (IPUs or IPDs). For
proper device operation of the HD [15, 13:9, 7, 1, 0] (for 13) or HD [13, 11:9, 7, 1, 0] (for 13B), do not oppose these pins with external
pullups/pulldowns at reset; however, the HD[6, 5, 2] (for 13) or HD[15, 6, 5, 2] (for 13B) pins can be opposed and driven during reset.
(2) 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.

5.2 Peripheral Pin Selection at Device Reset
Some C6713/13B peripherals share the same pins (internally MUXed) and are mutually exclusive (that is,
HPI, general-purpose input/output pins GP[15:8, 3, 1, 0], and McASP1).
•
HPI, McASP1, and GPIO peripherals
The HPI_EN (HD14 pin) is latched at reset. This pin selects whether the HPI peripheral pins or
McASP1 peripheral pins and GP[15:8, 3, 1, 0] pins are functionally enabled (see Table 5-2).

The device configuration register (DEVCFG) allows the user to control the pin availability of the McBSP0,
McBSP1, McASP0, I2C1, and timer peripherals. The DEVCFG register also offers the user control of the
EMIF input clock source and the timer output pins. For more detailed information on the DEVCFG register

5.4 Multiplexed Pins
Multiplexed (MUXed) 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 5-5 summarizes the peripheral pins affected by the HPI_EN (HD14 pin) and DEVCFG register.
Table 5-6 identifies the multiplexed pins on the C6713/13B devices, shows the default (primary) function
and the default settings after reset, and describes the pins, registers, etc., necessary to configure the
specific multiplexed functions.

SGUS049I–AUGUST 2003–REVISED SEPTEMBER 2009
5.6 Debugging Considerations
It is recommended that external connections be provided to peripheral selection/device configuration pins,
including HD[14, 8, 12 (for 13B only), 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 13) and HD[15, 13, 11:9, 7:5, 2:0] (for 13B)). For proper device operation of the HD[15,
13:9, 7, 1, 0] (for13) or HD[13, 11:9, 7, 1, 0] (for 13B), do not oppose the internal pullup/pulldown resistors
on these non-configuration pins with external pullup/pulldown resistors at reset. If an external controller
provides signals to these HD[15, 13:9, 7, 1, 0] (for 13) or HD[13, 11:9, 7, 1, 0] (for 13B) 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
list of routed out, 3-stated, or not-driven pins recommended for external pullup/pulldown resistors, and
internal pullup/pulldown resistors for all devices pins, etc., see Terminal Functions. However, the HD[6, 5,
2] (for 13) or HD[15, 6, 5, 2] (for 13B) non-configuration pins can be opposed and driven during reset.
For the internal pullup/pulldown resistors for all device pins, see the Terminal Functions table.

TERMINAL FUNCTIONS
The Terminal Functions table identifies the external signal names, the associated pin (ball) numbers along
with the mechanical package designator, the pin type (I, O/Z, or I/O/Z), whether the pin has any internal
pullup/pulldown resistors and a functional pin description. For more detailed information on device
configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see the Device
Configurations section of this data sheet.

sales office or authorized distributor.
6.2 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
TMS320™ DSP devices and support tools. Each TMS320 DSP commercial family member has one of
three prefixes: SMX, TMP, or SM/SMJ. TI recommends two of three possible prefix designators for
support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (SMX/TMDX) through fully qualified production devices/tools
(SM/SMJ/TMDS).
6.2.1 Device Development Evolutionary Flow
SMX
Preproduction device that is not necessarily representative of the final device
electrical specifications
TMP
Final silicon die that conforms to the device electrical specifications but has not
completed quality and reliability verification
SM/SMJ
Fully qualified production device
6.2.2 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
SMX and TMP devices and TMDX development-support tools are shipped with appropriate disclaimers
describing their limitations and intended uses. Experimental devices (SMX) may not be representative of a
final product and TI reserves the right to change or discontinue these products without notice.
SM/SMJ 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 (SMX or TMP) have a greater failure rate than the standard
production devices. TI 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, 20 is 200 MHz).
Figure 6-1 provides a legend for reading the complete device name for any TMS320C6000 DSP family
member.

7.2 Cache Configuration (CCFG) Register Description (13B)
The C6713B device includes an enhancement to the CCFG register. A P bit (CCFG.31) allows the
programmer to select the priority of accesses to L2 memory originating from the transfer crossbar (TC)
over accesses originating from the L1D memory system. An important class of TC accesses is EDMA
transfers, which move data to or from the L2 memory. While the EDMA normally has no issue accessing
L2 memory because of the high hit rates on the L1D memory system, there are pathological cases where
certain CPU behavior could block the EDMA from accessing the L2 memory for long enough to cause a
missed deadline when transferring data to a peripheral such as the McASP or McBSP. This can be
avoided by setting the P bit to 1 because the EDMA will assume a higher priority than the L1D memory
system when accessing L2 memory.
For more detailed information on the P-bit function and for silicon advisories concerning EDMA L2
memory accesses blocked, see the TMS320C6713, TMS320C6713B Digital Signal Processors Silicon
Errata (literature number SPRZ191).

7.3 Interrupts and Interrupt Selector
The C67x DSP core supports 16 prioritized interrupts, which are listed in Table 7-3. 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 7-3. However, their interrupt source may be reprogrammed to any one of the sources listed
in Table 7-4 (Interrupt Selector). Table 7-4 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 7-3) in the MUXH (address 0x019C0000) and MUXL (address 0x019C0004)
registers.

(1) 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 be 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).

7.4 External Interrupt Sources
The C6713/13B device supports many external interrupt sources as indicated in Table 7-5. 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 7-4 shaded rows). Because of pin multiplexing and module
usage, not all external interrupt sources are available at the same time.

7.5 EDMA Module and EDMA Selector
The C67x EDMA supports up to 16 EDMA channels. Four of the 16 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 7-7). By loading each EVTSELx register field with an EDMA
selector code, users can map any desired EDMA event to any specified EDMA channel. Table 7-6 lists the
default EDMA selector value for each EDMA channel.
See Table 7-8 and Table 7-11 for the EDMA Event Selector registers and their associated bit descriptions.

PLL and PLL Controller
The 320C6713/13B 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 (that is, DSP core, peripheral data bus, external memory interface, McASP,
and other peripherals). Figure 8-1 shows the PLL, the PLL controller, and the clock generator logic.

8.1 PLL Registers
The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST = 1), for
the PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the PLL reset
time value, see Table 8-1. 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 8-1 and Figure 8-1.
Under some operating conditions, the maximum PLL lock time may vary from the specified typical value.
For the PLL lock time values, see Table 8-1.

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 8-1 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 8-1, 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 8-3 for the PLL clocks input
and output frequency ranges.

(1) SYSCLK2 rate must be exactly half of SYSCLK1.
(2) See also the Electrical Specification (timing requirements and switching characteristics parameters) in
the Input and Output Clocks section of this data sheet.
(3) 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 8-1). 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 8-1).
During the programming transition of Divider D1 and Divider D2 (resulting in SYSCLK1 and SYSCLK2
output clocks, see Figure 8-1), 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 (that is, 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 the associated software bit
descriptions, see Table 8-4 through Table 8-11.

MULTICHANNEL AUDIO SERIAL PORT (McASP) PERIPHERALS
The 320C6713/13B device includes two multichannel audio serial port (McASP) interface peripherals
(McASP1 and McASP0). The McASP is a serial port optimized for the needs of multichannel audio
applications. With two McASP peripherals, the 320C6713/13B 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 different 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, and 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.
9.1 McASP Block Diagram
Figure 9-1 shows the major blocks along with external signals of the 320C6713/13B McASP1 and
McASP0 peripherals, and shows the eight 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.

9.2 Multichannel Time Division Multiplexed (TDM) Synchronous Transfer Mode
The McASP supports a multichannel 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 (two TDM
time slots, left and right).
The TDM synchronous serial transfer mode utilizes several control signals and one or more serial data
signals:
•
•
•
A bit clock signal (ACLKX for transmit, ACKLR for receive)
A frame sync signal (AFSX for transmit, AFSR for receive)
An (optional) high-frequency master clock (AHCLKX for transmit, AHCLKR for receive) from which the
bit clock is derived
•
One 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 S/PDIF, AES-3, IEC-60958, and CP-430 receiver 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, and CP-430 receivers; for example, the last slot interrupt.
9.3 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.

9.4 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:
•
•
•
•
•
•
•
Time slots per frame: 1 (burst/data driven), or 2,3...32 (TDM/time driven)
Time slot size: 8, 12, 16, 20, 24, 28, 32 bits per time slot
Data size: 8, 12, 16, 20, 24, 28, 32 bits (must be less than or equal to time slot)
Data alignment within time slot: left or right justified
Bit order: MSB or LSB first
Unused bits in time slot: Padded with 0, 1 or extended with value of another bit
Time 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 versus
McASP1. In addition, the McASP can automatically realign 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 adjustment reduces the amount of bit manipulation that the
DSP must perform and simplifies software architecture.
9.5 Digital Audio Interface Transmitter (DIT) Transfer Mode (Transmitter Only)
The McASP transmit section may also be configured in 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 a minimum):
•
One serial data pin (if the AUXCLK is used as the reference (see Figure 8-1)
OR
•
One 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 be 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 realign 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
simplifying software architecture.

9.6 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:
•
Input a high-frequency master clock (for example, 512 fS of the receiver) and 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.)
•
•
Transmit/receive data based on sample rate (for example, 44.1 kHz) using McASP0 while transmitting
and receiving at a different sample rate (for example, 48 kHz) on McASP1.
Use the DSP on-board AUXCLK to supply the system clock when the input source is an A/D converter.
9.7 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.

9.8 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 4-1).
When using the EDMA to service the McASP, the McASP DATA Port space, shown in Table 4-1, 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.
9.9 I2C
Having two I2C modules on the 320C6713/13B simplifies system architecture, since one module may be
used by the DSP to control local peripherals ICs (DACs, ADCs, etc.) while the other may be used to
communicate with other controllers in a system or to implement a user interface.
NOTE
I2C ports are compatible with Philips I2C Specification Revision 2.1 (January 2000).
The 320C6713/13B also includes two I2C serial ports for control purposes. Each I2C port supports:
•
•
•
•
•
•
Fast mode up to 400 Kbps (no fail-safe I/O buffers)
Noise filter to remove noise 50 ns or less
7- and 10-bit device addressing modes
Master (transmit/receive) and slave (transmit/receive) functionality
Events: DMA, interrupt, or polling
Slew-rate limited open-drain output buffers

This section discusses the logic and power-supply configuration of the SM320C6713-EP and
SM320C6713B-EP.
10.1 General-Purpose Input/Output (GPIO)
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
GPxDIR = 0
GPxDIR = 1
GP[x] pin is enabled.
GP[x] pin is an input.
GP[x] pin is an output.
where x represents one of the 15 through 0 GPIO pins.
Figure 10-1 shows the GPIO enable bits in the GPEN register for the C6713/13B 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 10-1 for the C6713/13B default
configuration.

10.2.1 Triggering, Wake-Up, and Effects
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 come 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 C6713 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.
The PLL needs to be enabled by writing a “1” to PLLEN bit (PLLCSR.0) before being able to enter either
PD3 (CSR.11) or PD2 (CSR.10) in order for these modes to have an effect.
For the TMS320C6713B device it is recommended to use the PLLPWDN bit (PLLCSR.1) to enter a deep
power−down state equivalent to PD3 since the PLLPWDN bit takes full advantage of the PLL power−down
feature.
The power-down modes (PD1, PD2 and PD3) 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 10-4 and described in Table 10-1. 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).

Figure 10-4. PWRD Field of the CSR
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 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 10-1 summarizes all the power-down
modes.

peripherals will not operate according to specifications.
10.3 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.

10.3.1 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 before, 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.
10.3.2 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 10-5).

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 printed circuit board (PCB) should include separate
power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.
10.4 Power-Supply Decoupling
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.
10.5 IEEE Std 1149.1 JTAG Compatibility Statement
The 320C6713/13B 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 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.

SGUS049I–AUGUST 2003–REVISED SEPTEMBER 2009
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 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 boundary scan functionality.
The TMS320C6713B 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 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
Note: The DESIGN−WARNING section of the TMS320C6713B BSDL file contains
information and constraints regarding proper device operation while in boundary scan
mode.
For more detailed information on the C6713B JTAG emulation, see the TMS320C6000 DSP Designing for
JTAG Emulation Reference Guide (literature number SPRU641).
10.6 EMIF Device Speed
The maximum EMIF speed on the C6713/13B 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 application report Using IBIS Models for Timing Analysis (literature number
SPRA839).
For ease of design evaluation, Table 10-2 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).

10.7 EMIF Big Endian Mode Correctness (C6713B Only)
The HD8 pin device endian mode (LENDIAN) selects the endian mode of operation (Little or Big Endian).
For the C6713/13B device Little Endian is the default setting.
The C6713B HD12 pin (EMIF Big Endian Mode Correctness) [EMIFBE] enhancement allows the flexibility
to change the EMIF data placement on the EMIF bus.
When using the default setting of HD12 = 1 for the C6713B, the EMIF will present 8-bit or 16-bit data on
the ED[7:0] side of the bus if using Little Endian mode (HD8 = 1), and to the ED[31:24] side of the bus if
using Big Endian mode. Figure 10-6 shows the mapping of 16-bit and 8-bit C6713B devices.

16-bit data on the ED[7:0] side of the bus, regardless of the endianess mode (see Figure 10-7)

10.8 Bootmode
The C6713/13B 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 C6713/13B has three types of boot modes:
•
Host 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 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.
•
•
Emulation 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. Before
beginning execution, the emulator sets a breakpoint at address 0. This prevents the execution of
invalid code by halting the CPU before executing the first instruction. Emulation boot is a good tool in
the debug phase of development.
EMIF 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 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. 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.

(2) Measured with average activity (50% high/50% low power) at 25°C case temperature and 100-MHz EMIF. 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: 2 channels at E1 rate
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: 2 channels at E1 rate
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 TMS320C6713/12C/11C

11.4.4 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 11-1 and Figure 11-6).
Figure 11-6 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.

(1) To ensure data setup time, simply program the strobe width wide enough. ARDY is internally synchronized. The ARDY signal is
recognized in the cycle for which the setup and hold time is met. To use ARDY as an asynchronous input, the pulse width of the ARDY
signal should be wide enough (for example, pulse width = 2E) to ensure setup and hold time is met.

clock (CLKIN) period multiplied by 8. For example, if the CLKIN period is 20 ns, the CPU clock (SYSCLK1) period is 20 ns x 8 = 160 ns.
Therefore, P = SYSCLK1 = 160 ns while internal reset is asserted.
(2) The internal reset is stretched exactly 512 x CLKIN cycles if CLKIN is used (CLKMODE0 = 1). If the input clock (CLKIN) is not stable
when RESET is deasserted, the actual delay time may vary.
(3) EMIF Z group consists of EA[21:2], ED[31:0], CE[3:0], BE[3:0], ARE/SDCAS/SSADS, AWE/SDWE/SSWE, AOE/SDRAS/SSOE, and
HOLDA.
EMIF low group consists of BUSREQ.

Figure 11-25. 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.

(1) 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.
(2) 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.
(3) A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIH min of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
(4) 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.
(5) Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall times are allowed.

Delay time, HSTROBE high to HRDY high(5)
(1) HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
(2) P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
(3) 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.
(4) 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.
(5) 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.

(1) CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also
inverted.
(2) P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
(3) 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.
(4) This parameter applies to the maximum McBSP frequency. Operate serial clocks (CLKR/X) in the reasonable range of 40/60 duty cycle.

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard

mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
