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.
