6.10

Burst Preamble PC and PD Bytes (addresses 09h - 0Ch)(Read Only)

6.10.1 BURST PREAMBLE BITS (PCX & PDX)

Default = xxh

Function:

The PC and PD burst preamble bytes are loaded into these four registers.

6.11

Volume Transition Control (address 0Dh)

6.11.1 SINGLE VOLUME CONTROL (SNGVOL)

Default = 0

Function:

The individual channel volume levels are independently controlled by their respective Volume Control

registers when this function is disabled. When enabled, the volume on all channels is determined by

the A1 Channel Volume Control register and the other Volume Control registers are ignored.

6.11.2 SOFT RAMP AND ZERO CROSS CONTROL (SZCX)

Default = 00

00 - Immediate Change

01 - Zero Cross

10 - Soft Ramp

11 - Soft Ramp on Zero Crossings

Function:

Immediate Change

When Immediate Change is selected, all level changes will take effect immediately in one step.

Zero Cross

Zero Cross Enable dictates that signal-level changes, either by attenuation changes or muting, will
