MASKx
The codec data in channel 1 (CH1X, CH1R) or channel 2 (CH2X,CH2R) respectively is
masked with these 6 register bits. The position of this 6 bit mask on the 8 or 16 bit value
respectively is determined by the MPx bits. If a mask bit is set to ’1’ the data in the
corresponding bit position is masked and thus always a ’1’. With a ’0’ the data passes
unchanged.

momentary AGC attenuation can be accessed directly by the microcontroller via XSR
register.
