ADC
An 8-bit value to program the volume ADC attenuation. The range is 0 dB to
Table 20 Mixer volume settings.
M
A 1-bit value to enable the digital master mute. This mute
control signal mutes the master playback signal after
mixing.
Table 21 Master mute
M
Two 1-bit values to enable the digital mutes of the mixer.
These signals can be used to independently mute the
I
ADC. These mute functions can only be used in the mixer
mode when the MIX bit is set HIGH.
The MT-ADC and MT-IIS bits can also be used to select
