Description
ADC DC-filter. Bit DC enables the digital DC-filter of the ADC.
Polarity ADC 2 control. Bit PAB controls the ADC 2 polarity.
Polarity ADC 1 control. Bit PAA controls the ADC 1 polarity.
Mute ADC 2. Bit MTB enables the digital mute of ADC 2.
Mute ADC 1. Bit MTA enables the digital mute of ADC 1.
ADC output data interface format. A 3-bit value to select the used data
format to the I
DAC gain switch. Bit DAG selects the DAC gain.
Filter selection. Bit FIL selects the interpolation filter characteristics.
192 kHz sampling mode selection. Bit DVD selects the oversampling rate
of the noise shaper.
Data interface selection. A 2-bit value to select the data interface
connection. Default 00. See
DAC input data interface format. A 3-bit value to select the used data
format to the I
