HPF[1:0]: High-Pass Filter Selection
Default value: 00
The PCM3793A/94A has a digital high-pass filter to remove dc voltage at the input of the ADC. The cutoff
frequency of the high-pass filter can be selected.

RMUL: Digital Soft Mute Control for L-Channel ADC
RMUR: Digital Soft Mute Control for R-Channel ADC
Default value: 1
The digital output of the ADC can be independently muted by setting RMUL and RMUR = 1. The digital data is
changed from the current attenuation level to mute level by a 1-dB step for every 8/f
S
time period. When PMUL
and PMUR are set to 0, the digital data is changed from the mute level to the current attenuation level by a 1-dB
step for every 8/f
S
time period. In the PCM3793A/94A, audible zipper noise can be reduced by selecting
zero-cross detection (register 86, ZCRS).

DSMC: Waiting Time for ADC Mute Off at Power Up
Default value: 0
The ADC digital output has an optional delay after power up when DSMC = 0. It is recommended to set
DSMC = 0.
DSMC = 0
