(Cont.)
DFTH
Digital Filter Bypass (or Through Mode) Control
This bit is Read/Write.
Default Value: 0
DFTH = 0
DFTH = 1
Digital Filter Enabled (default)
Digital Filter Bypassed for Either External Digital Filter or DSD Mode
The DFTH bit is used to enable or bypass the internal digital filter. This function is used when using the external
digital-filter interface or the DSD mode interface.
MONO
Monaural Mode Selection
This bit is Read/Write.
Default Value: 0
MONO = 0
MONO = 1
Stereo Mode (default)
Monaural Mode
The MONO function is used to change the operation mode from normal stereo mode to monaural mode. When
the monaural mode is selected, both DACs operate in balanced mode for the selected audio input data. Left and
Right channel data selection is set by the CHSL bit, as described below.
CHSL
Channel Selection for Monaural Mode
This bit is Read/Write.
Default Value: 0
This bit is available when MONO = 1.
CHSL = 0
CHSL = 1
L-Channel Selected (default)
R-Channel Selected
The CHSL bit is used to set the audio data selection for the monaural mode
.
OS[1:0]
Delta-Sigma Oversampling Rate Selection
These bits are available for Read/Write.
Default Value: 00
For DSD mode, this register is used to select the speed of BCK (pin 7) for the Analog FIR filter.

Operation Speed Select
64x (default)
Reserved
128x
32x
The OS bits are used to change the oversampling ratio of the delta-sigma modulator. This function is useful when
considering the output low-pass filter design that can handle a wide range of sampling rates. As an example,
selecting 128x for f
S
= 44.1kHz, 64x for f
S
= 96kHz, and 32x for f
S
= 192kHz operation would require a low-
pass filter with a single cutoff frequency to accommodate all three sampling rates.
