Notes: For best results, it is recommended that this feature be used in conjunction with the RMP_DN bit.

Single Volume Control (SNGLVOL)
Default = 0
0 - Disabled
1 - Enabled
Function:
The individual channel volume levels are independently controlled by their respective Volume Control
Bytes when this function is disabled. The volume on all channels is determined by the A1 Channel Volume
Control Byte, and the other Volume Control Bytes are ignored when this function is enabled.
Soft Volume Ramp-Up After Error (RMP_UP)
Default = 0
0 - Disabled
1 - Enabled
Function:
An un-mute will be performed after a LRCK/MCLK ratio change or error, and after changing the Functional
Mode. When this feature is enabled, this un-mute is affected, similar to attenuation changes, by the Soft
and Zero Cross bits in the Mode Control 3 register. When disabled, an immediate un-mute is performed
in these instances.
Mutec Polarity (MUTEC+/-)
Default = 0
0 - Active High
1 - Active Low
Function:
The active polarity of the MUTEC pin(s) is determined by this register. When set to 0 (default), the MUTEC
pins are high when active. When set to 1 the MUTEC pin(s) are low when active.
Note:
to be self biased into an active state, see
puts’ active polarity will be set by this bit.
Auto-Mute (AMUTE)
Default = 1
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute following the reception of 8192 consecutive audio sam-
ples of static 0 or -1. A single sample of non-static data will release the mute. Detection and muting is
done independently for each channel. The quiescent voltage on the output will be retained, and the Mute
Control pin will go active during the mute period. The muting function is affected, similar to volume control
changes, by the Soft and Zero Cross bits in the Mode Control 3 register.
During reset the MUTEC output pins are high impedance and the external mute circuitry will need
