Zero-crossing volume enable
Table 31.
The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital
zero-crossings no clicks will be audible.
Soft volume update enable
Table 32.
Configuration register F (addr 0x05)
Invalid Input detect mute enable
Table 33.
Setting the IDE bit enables this function, which looks at the input I
automatically mute if the signals are perceived as invalid.
Binary output mode clock loss detection
Table 34.
Detects loss of input MCLK in binary mode and outputs 50% of the duty cycle.
