The OS bits are used to change the oversampling rate of delta-sigma modulation. Use of this function enables the
designer to stabilize the conditions at the post low-pass filter for different sampling rates. As an application example,
programming to set 128 times in 44.1-kHz operation, 64 times in 96-kHz operation, and 32 times in 192-kHz operation
allows the use of only a single type (cutoff frequency) of post low-pass filter. The 128 f
S
oversampling rate is not
available at sampling rates above 100 kHz. If the 128 f
S
oversampling rate is selected, a system clock of more than
256 f
S
is required.
In DSD mode, these bits are used to select the speed of the bit clock for DSD data coming into the analog FIR filter.

When R/W = 0, a write operation is performed.
When R/W = 1, a read operation is performed.

pattern detect
The DZ bits are used to enable or disable the output zero flags, and to select the zero pattern in the DSD mode. The
DSD1794 sets zero flags when the number of 1s and 0s are equal in every 8 bits of DSD input data, or the DSD input
data is 1001 0110 continuously for 200 ms.
PCMZ: PCM Zero Output Enable
These bits are available for read and write.
Default value: 1
PCMZ = 0
PCMZ = 1
PCM zero output disabled
PCM zero output enabled (default)
The PCMZ bit is used to enable or disable the output zero flags in the PCM mode and the external DF mode. The
DSD1794 sets the zero flags when the input data is continuously zero for 1024 LRCKs in the PCM mode or 1024

8 WCKs in the external filter mode.
