ADC Mode
4.6.4.1
One-Line Mode Configuration #1 can support up to 8 channels of DAC data, 6 channels of ADC data and
2 channels of S/PDIF received data. This is the only configuration which will support up to 24-bit samples
at a sampling frequency of 48 kHz on all channels for both the DAC and ADC.
