PWM speed mode

Distortion compensation variable enable

Zero-crossing volume enable

The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital

zero-crossings no clicks will be audible.

Soft volume update enable

7.1.7

Configuration register F(address 0x05)

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.
