PMUL: Digital Soft Mute Control for DAL (DAC, L-Channel)
PMUR: Digital Soft Mute Control for DAR (DAC R-Channel)
Default value: 0
The digital input to the DAC can be independently muted or unmuted. The transition from the current volume
level to mute, or the return to the previous volume setting from mute, occurs at the rate of one 1-dB step for
each 8/fS time period. When PMUL and PMUR = 0, the digital data is increased from mute to the previous
attenuation level, and when PMUL and PMUR = 1, the digital data is decreased from the current attenuation
level to mute. In the PCM3793/94, audible zipper noise can be reduced by using zero-cross detection (register
85, ZCRS).
PMUL, PMUR = 0
Mute disabled (default)

ATL[5:0]: Digital Attenuation Setting for DAL (L-Channel DAC)
ATR[5:0]: Digital Attenuation Setting for DAR (R-Channel DAC)
Default value: 11 1111b
The digital inputs to the DAC can be independently attenuated. The attenuation of each digital input is controlled
in 1-dB step for every 8/fS time period. Audible zipper noise in the PCM3793/94 can be reduced by changing the
attenuation with zero-cross detection (register 85, ZCRS).
