Transition Control (Address 06h)
Single Volume Control (DAC_SNGVOL, ADC_SNGVOL)
Default = 0
Function:
The individual channel volume levels are independently controlled by their respective Volume Control reg-
isters when this function is disabled. When enabled, the volume on all channels is determined by the
AOUT1 and AIN1 Volume Control register and the other Volume Control registers are ignored.
Soft Ramp and Zero Cross Control (ADC_SZC[1:0], DAC_SZC[1:0])
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 volume-level changes will take effect immediately in one step.
Zero Cross
Zero Cross Enable dictates that signal level changes, either by gain changes, attenuation changes or mut-
ing, will occur on a signal zero crossing to minimize audible artifacts. The requested level change will oc-
cur after a timeout 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, either by gain changes, attenuation changes or muting, to be implement-
ed by incrementally ramping, 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 gain changes, 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 timeout 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 inde-
pendently monitored and implemented for each channel.
