This channel action continuously:
The channel generates center-aligned PWM waveform when AUX_TIMER2:CTL.MODE = UPDWN_PER.
The channel copies a new value written in AUX_TIMER2:CHnPCC to AUX_TIMER2:CHnCC when AUX_TIMER2:CNTR becomes 0. This action 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 action avoids period-jitter in PWM applications with time-varying periods.
For further description, see AUX_TIMER2:CHnEVCFG.CCACT in Section 20.8.7.
