DEM[1:0]: De-Emphasis Filter Selection
Default value: 00
The digital de-emphasis filter is in front of the interpolation filter. One of three de-emphasis filters can be
selected, corresponding to sampling 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 PCM3793/94 operates at low
sampling rates, less than 24 kHz with SCKI frequency less than 12.5 MHz, using this function with OVER = 1 is
recommended.
