Configuration register F (addr 0x05)
Setting the IDE bit enables this function, which looks at the input I2S data and clocking and
will automatically mute all outputs if the signals are perceived as invalid.
Detects loss of input MCLK in binary mode and will output 50% duty cycle to prevent audible
artifacts when input clocking is lost.
