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 enables 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
FMT[2:0]

The FMT[2:0] bits select the data format for the serial audio interface.
For the external digital filter interface mode (DFTH mode), this register is operated as shown in the APPLICATION
FOR EXTERNAL DIGITAL FILTER INTERFACE section of this data sheet.
DMF[1:0]: Sampling Frequency Selection for the De-Emphasis Function
These bits are available for read and write.
Default value: 00
DMF[1:0]
De-Emphasis Sampling Frequency Selection
00
Disabled (default)
01
48 kHz
10
44.1 kHz
11
32 kHz
The DMF[1:0] bits 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. A register map and filter
response plots are shown in the APPLICATION FOR DSD FORMAT (DSD MODE) INTERFACE section of this data
sheet.
