DAC polarity control. If this bit is logic 0 then the DAC output is not inverted; if this
bit is logic 1 then the DAC output is inverted.
Select noise shaper. If this bit is logic 0 then the third order noise shaper is
selected; if this bit is logic 1 then the fifth order noise shaper is selected.
Mixer position. Mixing is done before or after the sound processing unit (see
Table 53).
Mixer. If this bit is logic 0 then the mixer is disabled; if this bit is logic 1 then the mixer
is enabled (see Tables 48, 49 and 53).
DAC channel 2 input selection. Value to select the input mode to channel 2 of the
interpolator (see Table 54).
DAC channel 1 input selection. Value to select the input mode to channel 1 of the
interpolator (see Table 54).
