Function:
Implements mono mixes of the left and right channels as well as a left/right channel swap.
ALC Enable & Attack Rate (Address 1Ch)
ALC Enable (ALC_ENX)
Default: 0
0 - Disabled
1 - Enabled
Function:
Enables automatic level control for ADC channel x.
Note:
ALC Attack Rate (ARATE[5:0])
Default: 000000
Function:
Sets the rate at which the ALC attenuates the analog input from levels above the maximum setting in the
ALC threshold register.
The limiter attack rate is user-selectable but is also a function of the sampling frequency, Fs, and the SOFTx
& ZCROSSx bit settings unless the disable bit for each function is enabled.
ALC Release Rate (Address 1Dh)
ALC Release Rate (RRATE[5:0])
Default: 111111

When the ALC is enabled, the Attenuator and PGA volume is automatically controlled and should
not be adjusted manually.
