These bits should equal the sample rate of the ADC.
00 = 96 kHz.
01 = 48 kHz.
10 = 32 kHz.
11 = Reserved.
These bits determine the limit of the counter used in limited recovery mode.
00 = 3.
01 = 7.
10 = 15.
11 = 31.
These bits determine which recovery mode is used by the ALC section.
00 = No recovery.
01 = Normal recovery.
10 = Limited recovery.
11 = Reserved.
These bits limit detect mode.
0 = ALC is used when either channel exceeds the set limit.
1 = ALC is used only when both channels exceed the set limit.
These bits enable ALC.
0 = Disable ALC.
1 = Enable ALC.
