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