R/W
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

REFFS
0
R/W
Reference Sampling Rate
Note: This setting controls the coefficients in the deemphasis filter, the timeconstants in AGC,
and internal divider values that generate the clock for the auxiliary measurement ADC. If an Fsref
above 48 kHz is being used, then it is recommended to set this to the 48kHz setting, otherwise
either setting can be used.
0 => Fsref = 48.0 kHz
1 => Fsref = 44.1 kHz
