Cell phone Input PGA Powerdown
1 => Powerdown cell-phone input PGA
0 => Powerup cell phone input PGA
Cellphone Input PGA Settings.
0000000 => 34.5 dB
0000001 => 34 dB
0000010 => 33.5 dB
...
1000101 => 0 dB
1000110 => 0.5 dB
...
1011100 => 11.5 dB
1011101 => 12 dB
1011110 => 12 dB
1011111 => 12 dB
11xxxxx => 12 dB
Note: These bits are readonly when AGC is enabled for CP_IN (cell-phone input)
and reflect the gain applied by the AGC.

Cell phone Input PGA Flag (Read Only)
0 => Gain applied
≠
PGA register setting
1 => Gain applied = PGA register setting.
Note: This flag indicates when the softstepping for cell-phone input is completed.
When AGC is enabled for Cellphone input, this bit is readonly and acts as
Saturation Flag. The read value of this bit indicates the following
0 => AGC is not saturated
1 => AGC is saturated (PGA has reached –34.5 dB or max PGA applicable).
Buzzer Input PGA Powerdown
1 => Powerdown buzzer input PGA
0 => Powerup buzzer input PGA
Buzzer Input PGA settings.
1111 => 0 dB
1110 => 3 dB
1101 => 6 dB
1100 => 9 dB
1011 => 12 dB
1010 => 15 dB
1001 => 18 dB
1000 => 21 dB
0111 => 24 dB
0110 => 27 dB
0101 => 30 dB
0100 => 33 dB
0011 => 36 dB
0010 => 39 dB
0001 => 42 dB
0000 => 45 dB
Buzzer PGA Flag (Read Only)
0 => Gain Applied
≠
PGA Register setting
1 => Gain Applied = PGA register setting.
Note: This flag indicates when the softstepping for buzzer input is completed.
