FLT: Digital Filter Roll-Off Control
This bit is available for read and write.
Default value: 0
FLT Roll-Off Control
FLT = 0 Sharp roll-off (default)
FLT = 1 Slow roll-off
The FLT bit is used to select the digital filter roll-off characteristic. The filter responses for these selections are
shown in the Typical Characteristics section.
INZD: Infinite Zero Detect Mute Control
This bit is available for read and write.
Default value: 0
INZD Infinite Zero Detect Mute Setting
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 PCM1795 detects a zero condition in both channels. The infinite
zero detect mute function is not available 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
SRST: System Reset Control
This bit is available for write only.
Default value: 0
SRST System Reset Control
SRST = 0 Normal operation (default)
SRST = 1 System reset operation (generate one reset pulse)
The SRST bit is used to reset the PCM1795 to the initial system condition.
DSD: DSD Interface Mode Control
This bit is available for read and write.
Default value: 0
DSD DSD Interface Mode Control
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.
