In this configuration, channel 3 has full control (volume, EQ, etc…). On OUT4 channel the
external bridge control signals are muxed.
In this configuration the PWM slot phase is the following as shown in the next figures:
Figure 16. 2.1 channels (OCFG = 10) PWM slots.
Invalid input detect mute enable
Table 46.
Setting the IDE bit enables this function, which looks at the input I
automatically mute if the signals are perceived as invalid.
