I have a custom board with a ADSP-21261 DSP. SPORT01 is connected to A PCM3168 codec, which is configurated as Master.
24 bit, sampling frequency = 48KHz, BCLK is set to 256*48KHz, FS is generated every 1/48KHz with 50% duty.
I want to use a 8 Channel duplex TDM signal, since the codec supports 6 in and 8 outs.
My current status:
- SRU is set up
- PGC is set as system clock for the codec
- SPCTL0,1 set to SLEN24 and FSR
- SPMCTL01 is set to NCH7, MCEA
- SIG_SP1 interrupt is set and get triggered
First i want to get core driven mode running, what do I have to do in the interrupt? Where are the channelinformation in TXSP0A, RXSP1A?
Where can I get information or examples describing this art of setup?
