6.6.2

Invalid input detect mute enable

Setting the IDE bit enables this function, which looks at the input I2S data and will

automatically mute if the signals are perceived as invalid.

6.6.3

Binary output mode clock loss detection

Detects loss of input MCLK in binary mode and will output 50% duty cycle.

6.6.4

LRCK double trigger protection

Actively prevents double trigger of LRCLK.

6.6.5

Auto EAPD on clock loss

When active, issues a power device power down signal (EAPD) on clock loss detection.
