Configuration register F (addr 0x05)
Table 39.
Table 40.
Table 41.
Setting the IDE bit enables this function, which looks at the input I
will automatically mute all outputs if the signals are perceived as invalid.
Table 42.
Detects loss of input MCLK in binary mode and will output 50% duty cycle to prevent audible
artifacts when input clocking is lost.
