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.
ZOE: Zero Flag Pin Operation Control
This bit is available for read and write.
Default value: 0
ZOE = 0
DSD data input (default)
ZOE = 1
Zero flag output
The ZOE bit is used to change the DSDL (pin 1) and DSDR (pin 2) pin assignments. When the ZOE bit is set to 0, DSDL
and DSDR are inputs for L-channel and R-channel data. When the ZOE bit is set to 1, DSDL and DSDR become outputs
for the L-channel and R-channel zero flags, respectively. See the PCMZ and DZ[1:0] bit descriptions of register 21.
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 PDATA (pin 5) only, therefore the DSD1792 operates as a monaural DAC. When DFMS is set to
1, the DSD1792 can operate as a stereo DAC with inputs of input L-channel and R-channel data on DSDL (pin 1) and DSDR
(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 DSD1792 detects zero data in both channels continuously for 1024 sampling periods
(1/fS). The infinite zero detect mute function is not available in the DSD mode.
