function is affected, similar to attenuation changes, by the soft and zero cross bits (SZCMode[1:0]). See
“Volume and Muting Control” on page 36
Default = 0
Function:
The sub channel’s power PWM, logic-level PWM, and auxiliary serial data outputs will enter a mute state
when enabled. The muting function is affected, similar to attenuation changes, by the soft and zero cross
bits (SZCMode[1:0]). See
Default = 000
Function:
Sets the maximum level, below full scale, at which to limit and attenuate the output signal at the limiter
attack rate.
Default = 000
Function:
Sets a minimum level below full scale at which the limiter will begin to release its applied attenuation.
