Headset/Aux Input Mute
1 => Headset/Aux Input Mute
0 => Headset/Aux Input not muted
Note: If AGC is enabled and Headset/Aux Input is selected then ADMUT_HED+ADPGA_HED
reflects gain being applied by AGC.

ADC Headset/Aux PGA Settings
0000000 => 0 dB
0000001 => 0.5 dB
0000010 => 1.0 dB
………
1110110 => 59.0 dB
..........
1111111 => 59.5 dB
Note: If AGC is enabled and Headset/Aux Input is selected then ADMUT_HED+ADPGA_HED
reflects gain being applied by AGC.
If AGC is on, the decoding for read values is as follows
01110111 => +59.5 dB
01110110 => +59.0 dB
………
00000000 => 0 dB
……….
11101001 => 11.5 dB
11101000 => 12 dB

R/W
AGC Target Gain for Headset/Aux Input. These three bits set the AGC’s targeted ADC output
level.
000 => 5.5 dB
001 => 8.0 dB
010 => 10 dB
011 => 12 dB
100 => 14 dB
101 => 17 dB
110 => 20 dB
111 => 24 dB

R/W
AGC Time Constant for Headset/Aux Input. These four bits set the AGC attack and decay time
constants. Time constants remain same irrespective of any sampling frequency
