serial channels, one to control the codec‟s internal configuration registers and one to send and

receive digital audio samples. McBSP0 is used to send commands to the codec control interface

while McBSP1 is used for bi-directional digital audio data. The codec has a 12 MHz system

clock. The internal sample rate generate subdivides the 12 MHz clock to generate common

frequencies such as 48 KHz, 44.1 KHz and 8 KHz. The sample rate is set by the codec‟s

SAMPLERATE register. Figure 7.3 shows the codec interface on the C6713 DSK.

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 (D7-D10)

and 4 DIP switches (SW1) as a simple way to provide the user input/output. Both are accessed

by reading and writing to the CPLD registers.

The PC‟s USB port cannot be directly connected to DSP C6713. An XDS (eXtended

Development System) JTAG emulator is connected to the PC‟s USB port and DSP is

communicated through the JTAG emulator on the DSK. CCS uses USB port to control DSP via

JTAG port.
