This configuration will support up to 8 channels of DAC data 6 channels of ADC data and no channels of
S/PDIF received data. OLM Config #4 will handle up to 20-bit ADC samples at an Fs of 48 kHz and 24-bit
DAC samples at an Fs of 48 kHz. Since the ADC’s data stream is configured to use the SAI_SDOUT output
and the internal and external ADCs are clocked from the SAI_SP, the sample rate for the CODEC Serial
Port can be different from the sample rate of the Serial Audio Interface serial port.
