ADC Mode
4.5.4.2
This configuration will support up to 6 channels of DAC data or 6 channels of ADC data and will handle up
to 20-bit samples at a sampling-frequency of 96 kHz on all channels for both the DAC and ADC. The output
data stream of the internal and external ADCs is configured to use the ADC_SDOUT output and run at the
DAC Serial Port sample frequency.
