1.2 Functional Overview of the TMS320C6713 DSK
The DSP on the 6713 DSK interfaces to on-board peripherals through a 32-bit wide
EMIF (External Memory InterFace). The SDRAM, Flash and CPLD are all connected
to the bus. EMIF signals are also connected daughter card expansion connectors
which are used for third party add-in boards.
The DSP interfaces to analog audio signals through an on-board AIC23 codec and four
3.5 mm audio jacks (microphone input, line input, line output, and headphone output).
The codec can select the microphone or the line input as the active input. The analog
output is driven to both the line out (fixed gain) and headphone (adjustable gain)
connectors. McBSP0 is used to send commands to the codec control interface while
McBSP1 is used for digital audio data. McBSP0 and McBSP1 can be re-routed to the
expansion connectors in software.
A programmable logic device called a CPLD is used to implement glue logic that ties
the board components together. The CPLD has a register based user interface that
lets the user configure the board by reading and writing to its registers.
The DSK includes 4 LEDs and a 4 position DIP switch as a simple way to provide the
user with interactive feedback. Both are accessed by reading and writing to the CPLD
registers.
An included 5V external power supply is used to power the board. On-board switching
voltage regulators provide the +1.26V DSP core voltage and +3.3V I/O supplies. The
board is held in reset until these supplies are within operating specifications.
Code Composer communicates with the DSK through an embedded JTAG emulator
with a USB host interface. The DSK can also be used with an external emulator
through the external JTAG connector.

1.3 Basic Operation
The DSK is designed to work with TI’s Code Composer Studio development
environment and ships with a version specifically tailored to work with the board.
Code Composer communicates with the board through the on-board JTAG emulator.
To start, follow the instructions in the Quick Start Guide to install Code Composer.
This process will install all of the necessary development tools, documentation and
drivers.
After the install is complete, follow these steps to run Code Composer. The DSK must
be fully connected to launch the DSK version of Code Composer.
1) Connect the included power supply to the DSK.
2) Connect the DSK to your PC with a standard USB cable (also included).
3) Launch Code Composer from its icon on your desktop.
Detailed information about the DSK including a tutorial, examples and reference
material is available in the DSK’s help file. You can access the help file through Code
Composer’s help menu. It can also be launched directly by double-clicking on the file
c6713dsk.hlp in Code Composer’s docs\hlp subdirectory.

1.4 Memory Map
The C67xx family of DSPs has a large byte addressable address space. Program code
and data can be placed anywhere in the unified address space. Addresses are always
32-bits wide.
The memory map shows the address space of a generic 6713 processor on the left
with specific details of how each region is used on the right. By default, the internal
memory sits at the beginning of the address space. Portions of the internal memory
can be reconfigured in software as L2 cache rather than fixed RAM.
The EMIF has 4 separate addressable regions called chip enable spaces (CE0-CE3).
The SDRAM occupies CE0 while the Flash and CPLD share CE1. CE2 and CE3 are
generally reserved for daughtercards.

1.5 Configuration Switch Settings
The DSK has 4 configuration switches that allows users to control the operational state
of the DSP when it is released from reset. The configuration switch block is labeled
SW3 on the DSK board, next to the reset switch.
Configuration switch 1 controls the endianness of the DSP while switches 2 and 3
configure the boot mode that will be used when the DSP starts executing.
Configuration switch 4 controls the on-chip multiplexing of HPI and McASP signals
brought out to the HPI expansion connector. By default all switches are off which
corresponds to EMIF boot (out of 8-bit Flash) in little endian mode and HPI signals on
the HPI expansion connector.
1.6 Power Supply
The DSK operates from a single +5V external power supply connected to the main
power input (J5). Internally, the +5V input is converted into +1.26V and +3.3V using
separate voltage regulators. The +1.26V supply is used for the DSP core while the
+3.3V supply is used for the DSP's I/O buffers and all other chips on the board. The
power connector is a 2.5mm barrel-type plug.
There are three power test points on the DSK at JP1, JP2 and JP4. All I/O current
passes through JP2 while all core current passes through JP1. All system current
passes through JP4. Normally these jumpers are closed. To measure the current
passing through remove the jumpers and connect the pins with a current measuring
device such as a multimeter or current probe.
It is possible to provide the daughter card with +12V and -12V when the external power
connector (J6) is used.

2.1 CPLD (Programmable Logic)
The C6713 DSK uses an Altera EPM3128TC100-10 Complex Programmable Logic
Device (CPLD) device to implement:
• 4 Memory-mapped control/status registers that allow software
control of various board features.
• Control of the daughter card interface and signals.
• Assorted "glue" logic that ties the board components together.
2.1.1 CPLD Overview
The CPLD logic is used to implement functionality specific to the DSK. Your own
hardware designs will likely implement a completely different set of functions or take
advantage of the DSPs high level of integration for system design and avoid the use
of external logic completely.
The CPLD implements simple random logic functions that eliminate the need for
additional discrete devices. In particular, the CPLD aggregates the various reset
signals coming from the reset button and power supervisors and generates a global
reset.
The EPM3128TC100-10 is a 3.3V (5V tolerant), 100-pin QFP device that provides
128 macrocells, 80 I/O pins, and a 10 ns pin-to-pin delay. The device is
EEPROM-based and is in-system programmable via a dedicated JTAG interface
(a 10-pin header on the DSK). The CPLD source files are written in the industry
standard VHDL (Hardware Design Language) and included with the DSK.

2.1.2 CPLD Registers
The 4 CPLD memory-mapped registers allows users to control CPLD functions in
software. On the 6713 DSK the registers are primarily used to access the LEDs and
DIP switches and control the daughter card interface. The registers are mapped into
EMIF CE1 data space at address 0x90080000. They appear as 8-bit registers with a
simple asynchronous memory interface. The following table gives a high level
overview of the CPLD registers and their bit fields:
The table below shows the bit definitions for the 4 registers in CPLD.
2.1.3 USER_REG Register
USER_REG is used to read the state of the 4 DIP switches and turn the 4 LEDs on or
off to allow the user to interact with the DSK. The DIP switches are read by reading the
top 4 bits of the register and the LEDs are set by writing to the low 4 bits.

2.1.4 DC_REG Register
DC_REG is used to monitor and control the daughter card interface. DC_DET detects
the presence of a daughter card. DC_STAT and DC_CNTL provide simple
communications with the daughter card through readable status lines and writable
control lines.
The daughter card is released from reset when the DSP is released from reset.
DC_RST can be used to put the card back in reset.
2.1.5 VERSION Register
The VERSION register contains two read only fields that indicate the BOARD and
CPLD versions. This register will allow your software to differentiate between
production releases of the DSK and account for any variances. This register is not
expected to change often, if at all.

2.1.6 MISC Register
The MISC register is used to provide software control for miscellaneous board
functions. On the 6713 DSK, the MISC register controls how auxiliary signals are
brought out to the daughter-card connectors.
McBSP0 and McBSP1 are usually used as the control and data ports of the on-board
AIC23 codec. The power-on state of these bits (both 0s) represents that situation.
Set the corresponding McBSP select bit to use the McBSP with a daughter card
instead.
The Flash and CPLD share CE1 which means that the highest DSP address bit (A21)
is used to differentiate between the two. The FLASH_PAGE bit is driven to the Flash as
a replacement for that address line which is connected to A19 of the Flash. On a
standard DSK, the on-board Flash is not large enough for this bit to be significant.
FLASH_PAGE is only useful if the board is re-populated with a larger pin-compatible
Flash chip.
The scratch bits are unused. They can be set to any value.
