ADC Digital High Pass Filter Cut-Off
Frequency (fc)
00 = Hi-fi mode (fc=4Hz at fs=48kHz)
01 = Voice mode 1 (fc=127Hz at fs=16kHz)
10 = Voice mode 2 (fc=130Hz at fs=8kHz)
11 = Voice mode 3 (fc=267Hz at fs=8kHz)
(Note: fc scales with sample rate. See
Table 21 for cut-off frequencies at all
supported sample rates.)
Left ADC Invert
0 = Left ADC output not inverted
1 = Left ADC output inverted
Right ADC Invert
0 = Right ADC output not inverted
1 = Right ADC output inverted
ADC Volume Update
Writing a 1 to this bit will cause left and
right ADC volume to be updated
simultaneously
