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
ATLD: Attenuation Load Control
This bit is available for read and write.
Default value: 0
ATLD = 0
Attenuation control disabled (default)
ATLD = 1
Attenuation control enabled
The ATLD bit is used to enable loading of the attenuation data contained in registers 16 and 17. When ATLD = 0,
the attenuation settings remain at the previously programmed levels, ignoring new data loaded from registers 16 and
17. When ATLD = 1, attenuation data written to registers 16 and 17 is loaded normally.
FMT[2:0]: Audio Interface Data Format
These bits are available for read and write.
Default value: 101
For the external digital filter interface mode (DFTH mode), this register is operated as shown in the Application for
Interfacing With an External Digital Filter section of this data sheet.

The FMT[2:0] bits are used to select the data format for the serial audio interface.
DMF[1:0]: Sampling Frequency Selection for the De-Emphasis Function
These bits are available for read and write.

The DMF[1:0] bits are used to select the sampling frequency used by the digital de-emphasis function when it is
enabled by setting the DME bit. The de-emphasis curves are shown in the TYPICAL PERFORMANCE CURVES
section of this data sheet.
For the DSD mode, analog FIR filter performance can be selected using this register. Filter response plots are shown
in the TYPICAL PERFORMANCE CURVES section of this data sheet. A register map is shown in the Configuration
for the DSD Interface Mode section of this data sheet.
