Function:
The digital-to-analog converters of the CS42426 will mute the output 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 MUTEC pin will go active during the mute period. The muting function is af-
fected, similar to volume control changes, by the Soft and Zero Cross bits (SZC[1:0]).
An un-mute will be performed after executing a filter mode change, after a MCLK/LRCK ratio change
or error, and after changing the Functional Mode. When this feature is enabled, this un-mute is affect-
ed, similar to attenuation changes, by the Soft and Zero Cross bits (SZC[1:0]). When disabled, an
immediate un-mute is performed in these instances.
A mute will be performed prior to executing a filter mode or de-emphasis mode change. When this
feature is enabled, this mute is affected, similar to attenuation changes, by the Soft and Zero Cross
bits (SZC[1:0]). When disabled, an immediate mute is performed prior to executing a filter mode or
de-emphasis mode change.
The digital-to-analog converter outputs of the CS42426 will mute when enabled. The quiescent volt-
age on the outputs will be retained. The muting function is affected, similar to attenuation changes,
by the Soft and Zero Cross bits (SZC[1:0]).

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