This channel action continuously does the following:
The channel generates an edge-aligned PWM waveform when AUX_TIMER2:CTL.MODE = UP_PER.
The channel copies a new value written in AUX_TIMER2:CHnPCC to AUX_TIMER2:CHnCC when AUX_TIMER2:CNTR becomes 0. This prevents jitter on the edges of the generated PWM signal. Similarly, the timer copies a new value written in AUX_TIMER2:SHDWTARGET to AUX_TIMER2:TARGET when AUX_TIMER2:CNTR becomes 0. This avoids period-jitter in PWM applications with time-varying period.
For further description, see AUX_TIMER2:CHnEVCFG.CCACT in Section 20.8.7.
