ZCE
Zero-crossing volume enable:
1: volume adjustments will only occur at digital zero-
crossings
0: volume adjustments will occur immediately
The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital
zero-crossings, no clicks will be audible.

ZDE
Zero-detect mute enable: setting of 1 enables the
automatic zero-detect mute
Setting the ZDE bit enables the zero-detect automatic mute. The zero-detect circuit looks at
the input data to each processing channel after the channel-mapping block. If any channel
receives 2048 consecutive zero value samples (regardless of fs), then that individual
channel is muted if this function is enabled.
