Function:
The PC and PD burst preamble bytes are loaded into these four registers.
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.
When Immediate Change is selected, all level changes will take effect immediately in one step.
Zero Cross Enable dictates that signal-level changes, either by attenuation changes or muting, will
