DME: Digital De-Emphasis Control
This bit is available for read and write.
Default value: 0
DME = 0
De-emphasis disabled (default)
DME = 1
De-emphasis enabled
The DME bit is used to enable or disable the de-emphasis function for both channels.
MUTE: Soft Mute Control
This bit is available for read and write.
Default value: 0
MUTE = 0
MUTE disabled (default)
MUTE = 1
MUTE enabled
The MUTE bit is used to enable or disable the soft mute function for both channels.
Soft mute is operated as a 256-step attenuator. The speed for each step to –
∞ dB (mute) is determined by the attenuation
rate selected in the ATS register.

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
REV: Output Phase Reversal
This bit is available for read and write.
Default value: 0
REV = 0
Normal output (default)
REV = 1
Inverted output
The REV bit is used to invert the output phase for both channels.
ATS[1:0]: Attenuation Rate Select
These bits are available for read and write.
Default value: 00
