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.
The digital-to-analog converter outputs of the CS42518 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]).
The Digital Volume Control registers allow independent control of the signal levels in 0.5 dB incre-
ments from 0 to -127 dB. Volume settings are decoded as shown in
are implemented as dictated by the Soft and Zero Cross bits (SZC[1:0]). All volume settings less than
-127 dB are equivalent to enabling the MUTE bit for the given channel.
