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.
An un-mute will be performed after executing a filter mode change, after a LRCK/MCLK ratio change
or error, and after changing the Functional Mode. When this feature is enabled, this un-mute is ef-
fected, 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.
Note: For best results, it is recommended that this feature be used in conjunction with the RMP_DN
bit.
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: When the on board mute circuitry is designed for active low, the MUTEC outputs will be high
(un-muted) for the period of time during reset and before this bit is enabled to 1.
The Digital-to-Analog converter output will mute following the reception of 8192 consecutive audio
samples 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.
