PLAYBACK PATH CONFIGURATION
Register 16412 (0x401C), Playback Mixer Left Control
Bit 5, Left DAC Mute
This bit mutes the left DAC output. It does not have any slew
and is updated immediately when the register write has been
completed. This results in an abrupt cutoff of the audio output
and should therefore be preceded by a soft mute in the
SigmaDSP core or a slew mute using the DAC attenuator.
Bits[4:1], Left Playback Beep Gain
These bits set the gain of the beep signal in the left playback
path. If the zero-crossing detector is activated, the change in
gain is applied on the next detected zero crossing or when the
timeout period expires, whichever comes first. The gain control
is in 3 dB increments and should not be incremented more than
3 dB at a time in order to avoid audible artifacts on the output.
