Codec will power up in an
unknown state once all clocks
and data are valid. It is
recommended that the user
setup up the codec via the
control port before applying
MCLK.

Normal Operation
1. VQ = VA/2.
2. Aout bias = VQ.
3. Audio signal generated per register settings.
Analog Output Freeze
1. VQ = VA/2.
2. Aout bias = VQ + last audio sample.
3. DAC Modulators stop operation.
4. Audible pops.
Analog Output Mute
1. VQ = VA/2.
2. Aout bias = VQ.
3. DAC outputs muted.
4. No audio signal generated.
ERROR: MCLK/LRCK ratio change
ERROR: MCLK removed
