Silence detector switch
A 1-bit value to enable the silence detector.
Table 38
Silence detector switch
9.20
Mute
Three 1-bit values to enable the digital mute. Bit MT is the
master mute, using bit MTA the signal from the digital
interface can be soft muted when the DAC mixer is
enabled and using bit MTB the signal from ADC can be
soft muted.

Mute
9.21
Quick mute mode
A 1-bit value to enable the quick mute function of the
master mute.

Quick mute mode settings
9.22
De-emphasis
A 3-bit value to enable the digital de-emphasis filter.

9.23
ADC input amplifier gain
Two 4-bit values to program the gain of the input
amplifiers. Bits IA applies for input amplifier A and bits IB
to input amplifier B.
