AGCTG_CELL
AGC Target Gain for Cellphone 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
AGC Time Constant for Cell Input.
These four bits set the AGC attack and decay time constants. Time constants remain
the same irrespective of any sampling frequency
