Description
Polarity voice ADC control. Bit PVA controls the voice ADC polarity.
Mute voice ADC. Bit MTV enables the digital mute of the voice ADC.
Voice ADC interface format. Bit VIF selects the data interface format
of the voice ADC.
1 = polarity is inverted
0 = polarity is not-inverted (default)
1 = ADC 1 is soft muted
0 = ADC 1 is not muted (default)
1 = mono-channel format
0 = I
