Zero-Crossing Volume Enable

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

ings no clicks will be audible.

7.6.7

Soft Volume Update Enable

The STA326 includes a soft volume algorithm that will step through the intermediate volume values at a

predetermined rate when a volume change occurs. By setting SVE=0 this can be bypassed and volume

changes will jump from old to new value directly. This feature is only available if individual channel volume

bypass bit is set to ‘0’.
