DEM[1:0]: De-Emphasis Filter Selection
Default value: 00
A digital de-emphasis filter is in front of the interpolation filter. One of three de-emphasis filters can be selected
corresponding to thesampling rate, 32 kHz, 44.1 kHz, or 48 kHz.

OVER: Oversampling Control for Delta-Sigma DAC
Default value: 0
This bit is used to control the oversampling rate of delta-sigma DAC. When the PCM3793A/94A operates at low
sampling rates (less than 24 kHz) and the SCKI frequency is less than 12.5 MHz, OVER = 1 is recommended.
