I have a C6727 interfaced to a PCM3168 CODEC.
The McASP outputs an 8 slot TDM frame of data with a single bit LRCLKDA. The problem is that the codec outputs the correct signal on channels 1 to 4 but nothing on channels 5 to 8.
The CODEC setup is:
SCKI = BCKDA = BCKAD = 8.192 MHz. LRCKDA = LRCKAD = 32 kHz
The DAC is programmed:
Single Rate, Slave Mode, 24Bit left-justified TDM format, ...all else is default state.
Why is the CODEC not processing the last 4 channels of data?
Thanks for your help......
