16.22 PSC Synchronization

AT90PWM216/316
This signal can be selected between all falling or rising edge of PSCn0 or PSCn1 outputs.
In center aligned mode, OCRnRAH/L is not used, so it can be used to specified the synchroniza-
tion of the ADC. It this case, it’s minimum value is 1.
As each PSC can be dedicated for one function, each PSC has its own interrupt system (vector
...)
List of interrupt sources:
2 or 3 PSC can be synchronized together. In this case, two waveform alignments are possible:
Figure 16-38. PSC Run Synchronization
If the PSCm has its PARUNn bit set, then it can start at the same time than PSCn-1.
• Counter reload (end of On Time 1)
• PSC Input event (active edge or at the beginning of level configured event)
• PSC Mutual Synchronization Error
• The waveforms are center aligned in the Center Aligned mode if master and slaves are all
• The waveforms are edge aligned in the 1, 2 or 4 ramp mode
with the same PSC period (which is the natural use).
