of the voice ADC in the WSV-out mode. Default 01; see
WSV mode selection. A 1-bit value to select the WSV mode of the voice
ADC. If bit WSM = 1 (default), then WSV-in mode; if bit WSM = 0, then
WSV-out mode.
Voice ADC high-pass filter setting. A 2-bit value to enable the high-pass
filter of the voice ADC. Default 01; see
Polarity voice ADC control. A 1-bit value to control the voice ADC
polarity. If bit PVA = 1, then the polarity is inverted; if bit PVA = 0 (default),
then the polarity is non-inverted.
Mute voice ADC. A 1-bit value to enable the digital mute of the voice
ADC. If bit MTV = 1, then the voice ADC is soft muted; if bit MTV = 0
(default), then the voice ADC is not muted.
Voice ADC interface format. A 1-bit value to select the data interface
format of the voice ADC. If bit VIF = 1, then mono-channel format; if
bit VIF = 0 (default), then I
