CC
If a Retrigger event (EVCTRL.EVACTn = 0x1, RETRIGGER) occurs exactly at the Channel Compare Match [n] time, the next Waveform Output [n] is corrupted.
Workaround
Use two channels to store their two successive (n and n+1) CC register values and combine their related waveform outputs to make signal redundancy.
