Forced mute
Forced mute results when the FMUT command of $AX is set to 1.
Forced mute fixes the PWM output that is input to the LPF block to low.
When setting FMUT, set OPSL2 to 1. (See the $AX commands.)
Zero detection mute
The analog mute is applied to the left and right channels, respectively, when the ZMUT command of $9X is
set to 1 and the zero data is detected for the left or right channel.
(See "Zero data detection".)
When the ZMUT command of $9X is set to 1, the analog mute is applied even if the mute flag output
condition is met. When the zero detection mute is on, set the DCOF, ZDPL command of $9X to 1.
