Configuration register F (address 0x05)

7.6.1

Output configuration selection

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

automatically mutes all outputs if the signals are invalid.

Detects loss of input MCLK in binary mode and outputs 50% duty cycle to prevent audible

noise when input clocking is lost.
