These bits are used to select the analog output source.
ADCx Volume Control: ADCA (Address 10h) & ADCB (Address 11h)
The level for each channel of the ADC can be adjusted in 0.5 dB increments as dictated by the ADC Soft
and Zero Cross bits (ADC_SOFT) from +12 to -84 dB. Levels are decoded in two’s complement, as shown
in the table below.
DAC1x Volume Control: DAC1A (Address 12h) & DAC1B (Address 13h)
The level for each channel of DAC1 output can be adjusted in 0.5 dB increments as dictated by the DAC1
Soft and Zero Cross bits (DAC1_SOFT & DAC1_ZC) from 0 to -127.5 dB. Levels are decoded as unsigned,
as shown in the table below.
