CS42526
6.11.3 AUTO-MUTE (AMUTE)
Default = 1
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converters of the CS42526 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]).
6.11.4 SERIAL AUDIO INTERFACE SERIAL PORT MUTE (MUTE SAI_SP)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, the Serial Audio Interface port (SAI_SP) will be muted.
6.11.5 SOFT VOLUME RAMP-UP AFTER ERROR (RMP_UP)
Default = 0
0 - Disabled
1 - Enabled
Function:
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 im-
mediate un-mute is performed in these instances.
Note: For best results, it is recommended that this bit be used in conjunction with the RMP_DN bit.
6.11.6 SOFT RAMP-DOWN BEFORE FILTER MODE CHANGE (RMP_DN)
Default = 0
0 - Disabled
1 - Enabled
Function:
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.
Note: For best results, it is recommended that this bit be used in conjunction with the RMP_UP bit.
