R/W
Handset Input Mute
1 => Handset Input Mute
0 => Handset Input not muted
Note: If AGC is enabled and handset Input is selected then
ADMUT_HND+ADPGA_HND will reflect gain being applied by AGC.

R/W
ADC Handset 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 handset Input is selected then
ADMUT_HND+ADPGA_HND will reflect 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
……….
11101000 => 12 dB

R/W
AGC Target Gain for Handset 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

AGCTC_HND
0000
R/W
AGC Time Constant for Handset Input.
These four bits set the AGC attack and decay time constants. Time
constants remain the same irrespective of any sampling frequency.

R/W
AGC Enable for Handset Input
0 => AGC is off for Handset Input
(ADC PGA is controlled by ADMUT_HND+ADPGA_HND)
1 => AGC is on for Handset Input
(ADC PGA is controlled by AGC)
