CS4384
The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Vol-
ume Control Bytes when this function is disabled. The volume on both AOUTAx and AOUTBx are deter-
mined by the A Channel Attenuation and Volume Control Bytes (per A-B pair), and the B Channel Bytes
are ignored when this function is enabled.
6.7.3
Single Volume Control (SNGLVOL)
Default = 0
0 - Disabled
1 - Enabled
Function:
The individual channel volume levels are independently controlled by their respective Volume Control
Bytes when this function is disabled. The volume on all channels is determined by the A1 Channel Volume
Control Byte, and the other Volume Control Bytes are ignored when this function is enabled.

Ramp and Mute (Address 08h)
6.8.1
Soft Ramp and Zero Cross Control (SZC)
Default = 10
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 occur
on a signal zero crossing to minimize audible artifacts. The requested level change will occur after a time-
out period between 512 and 1024 sample periods (10.7 ms to 21.3 ms at 48 kHz sample rate) if the signal
does not encounter a zero crossing. The zero cross function is independently monitored and implemented
for each channel.
Soft Ramp
Soft Ramp allows level changes, both muting and attenuation, to be implemented by incrementally ramp-
ing, in 1/8 dB steps, from the current level to the new level at a rate of 1 dB per 8 left/right clock periods.
Soft Ramp on Zero Crossing
Soft Ramp and Zero Cross Enable dictates that signal level changes, either by attenuation changes or
muting, will occur in 1/8 dB steps and be implemented on a signal zero crossing. The 1/8 dB level change
will occur after a time-out period between 512 and 1024 sample periods (10.7 ms to 21.3 ms at 48 kHz
sample rate) if the signal does not encounter a zero crossing. The zero cross function is independently
monitored and implemented for each channel.
