3.1.3 Serial Audio Input Interface First Bit
3.1.4 Zero-Crossing Volume Enable
The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital zero-crossings,
"zipper noise" is eliminated
3.1.5 Dynamic Range Compression/Anti-Clipping Bit
Both limiters can be used in one of two ways, anti-clipping or dynamic range compression. When used in anti-
clipping mode the limiter threshold values are constant and dependent on the gain/attenuation settings applied
to the input signal. In dynamic range compression mode the limiter threshold values vary with the volume set-
tings allowing for limiting to occur independently of the gain/attenuation but dependent on the input signal
3.2 Configuration Register C (address 02h)
3.2.1 DDX Power Output Mode
The DDX Power Output Mode selects how the DDX output timing is configured. Different power devices use
different output modes. The DDX recommended use is OM = 00. The variable mode uses the OMVx bits for
adjustment
