DAC Channel Master Volume Control
00 => Left channel and right channel have independent volume controls
01 => Left channel volume control is the programmed value of the right channel volume control.
10 => Right channel volume control is the programmed value of the left channel volume control.
11 => same as 00

Reference Sampling Rate.
This setting controls the coefficients in the de-emphasis filter. If an
Fsref above 48 kHz is being used, then it is recommended to set this to the 48-kHz setting,
otherwise either setting can be used.
0 => Fsref = 48.0 kHz
1 => Fsref = 44.1 kHz

DAC Max Output Signal Swing and Common Mode Voltage
00 => DAC max output signal swing = 2.0 V, VCM = 1.35 V
01 => DAC max output signal swing = 2.192 V (only recommended for analog supply of 3.0 V
and digital supply of 1.65 V and above), VCM = 1.48 V
10 => DAC max output signal swing = 2.402 V (only recommended for analog supply of 3.3 V
and digital supply of 1.8 V and above), VCM = 1.62 V
11 => DAC max output signal swing = 2.633 V (only recommended for analog supply of 3.6 V
and digital supply of 1.95 V), VCM = 1.78 V
