7.2.9
Setting the IDE bit enables this function, which looks at the input I
automatically mute if the signals are perceived as invalid.
Detects loss of input MCLK in binary mode and will output 50% duty cycle.
Actively prevents double trigger of LRCLK.
When active will issue a device power down signal (EAPD) on clock loss detection
Configuration register I (0x08)
This feature utilizes an ADC on SDI78 that provides power supply ripple information for
correction. Registers PSC1, PSC2, PSC3 are utilized in this mode.
