OPE: DAC Operation Control
This bit is available for read and write.
Default value: 0
OPE = 0
DAC operation enabled (default)
OPE = 1
DAC operation disabled
The OPE bit is used to enable or disable the analog output for both channels. Disabling the analog outputs forces
them to the bipolar zero level (BPZ) even if digital audio data is present on the input.
DFMS: Stereo DF Bypass Mode Select
This bit is available for read and write.
Default value: 0
DFMS = 0
Monaural (default)
DFMS = 1
Stereo input enabled
The DFMS bit is used to enable stereo operation in DF bypass mode. In the DF bypass mode, when DFMS is set
to 0, the pin for the input data is DATA (pin 5) only, therefore the PCM1792 operates as a monaural DAC. When DFMS
is set to 1, the PCM1792 can operate as a stereo DAC with inputs of L-channel and R-channel data on ZEROL
(pin 1) and ZEROR (pin 2), respectively.
FLT: Digital Filter Rolloff Control
This bit is available for read and write.
Default value: 0
FLT = 0
Sharp rolloff (default)
FLT = 1
Slow rolloff
The FLT bit is used to select the digital filter rolloff characteristic. The filter responses for these selections are shown
in the TYPICAL PERFORMANCE CURVES section of this data sheet.
INZD: Infinite Zero Detect Mute Control
This bit is available for read and write.
Default value: 0
INZD = 0
Infinite zero detect mute disabled (default)
INZD = 1
Infinite zero detect mute enabled
The INZD bit is used to enable or disable the zero detect mute function. Setting INZD to 1 forces muted analog outputs
to hold a bipolar zero level when the PCM1792 detects a zero condition in both channels. The infinite zero detect
mute function is disabled in the DSD mode.

R/W: Read/Write Mode Select
When R/W = 0, a write operation is performed.
When R/W = 1, a read operation is performed.
Default value: 0
