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
SRST: System Reset Control
This bit is available for write only.
Default value: 0
SRST = 0
Normal operation (default)
SRST = 1
System reset operation (generate one reset pulse)
The SRST bit is used to reset the DSD1792 to the initial system condition.
DSD: DSD Interface Mode Control
This bit is available for read and write.
Default value: 0
DSD = 0
DSD interface mode disabled (default)
DSD = 1
DSD interface mode enabled
The DSD bit is used to enable or disable the DSD interface mode.
DFTH: Digital Filter Bypass (or Through Mode) Control
This bit is available for read and write.
Default value: 0
DFTH = 0
Digital filter enabled (default)
DFTH = 1
Digital filter bypassed for external digital filter
The DFTH bit is used to enable or disable the external digital filter interface mode.
MONO: Monaural Mode Selection
This bit is available for read and write.
Default value: 0
MONO = 0
Stereo mode (default)
MONO = 1
Monaural mode
The MONO function is used to change the operation mode from the normal stereo mode to the monaural mode. When the
monaural mode is selected, both DACs operate in a balanced mode for one channel of audio input data. Channel selection
is available for L-channel or R-channel data, determined by the CHSL bit as described immediately following.
CHSL: Channel Selection for Monaural Mode
This bit is available for read and write.
Default value: 0
This bit is available when MONO = 1.
CHSL = 0
L-channel selected (default)
CHSL = 1
R-channel selected
The CHSL bit selects L-channel or R-channel data to be used in monaural mode.
