A 1-bit value to enable the silence detector.
Table 38 Silence detector switch
9.20
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.
Table 39 Mute
9.21
A 1-bit value to enable the quick mute function of the
master mute.
Table 40 Quick mute mode settings
9.22
