BCK[1:0]
BCK frequency of voice ADC.
A 2-bit value to select the BCK
frequency of the voice ADC in the WSV-out mode. Default 01.
See
Table 34
.
WSM
WSV mode selection.
Bit WSM selects the WSV mode of the voice
ADC
1 = WSV-in mode (default)
0 = WSV-out mode
VH[1:0]
Voice ADC high-pass filter setting.
A 2-bit value to enable the
high-pass filter of the voice ADC. Default 01. See
