Which pins should be used for ADC or DAC TDM bus? (eg., 6CH audio ADC or 8CH DAC)
Can you please let us know whether you are using a CODEC? If yes, then we would suggest you to refer the ADSP-BF706 EZ-kit mini schematic which shows how ADAU1761(SigmaDSP® low power, stereo audio codec) is connected to ADSP-BF706 Ez-kit mini via TWI and SPORT0 interfaces.
The ADSP-BF706 Ez-kit mini schematics can be downloaded from the below link.
