Set minimum gain of PGA when using ALC:
000=-12dB
001=-6dB
010=0dB
011=+6dB
100=+12dB
101=+18dB
110=+24dB
111=+30dB
ALC zero cross detection.
0 = disabled (recommended)
1 = enabled
It is recommended that zero cross is not used in
conjunction with the ALC or Limiter functions
ALC hold time before gain is increased.
0000 = 0ms
0001 = 2.67ms
0010 = 5.33ms
… (time doubles with every step)
1111 = 43.691s
ALC target – sets signal level at ADC input
0000 = -28.5dB FS
0001 = -27.0dB FS
… (1.5dB steps)
1110 = -7.5dB FS
1111 = -6dB FS
Determines the ALC mode of operation:
0=ALC mode
1=Limiter mode.
