Hello everybody,

I've a little bit trouble with the compare match generated by the CCU8. If the CompareValue raises above 49,2% of the PeriodValue the compare match interrupt is doing strange things. It "jumps" from 49% to around 70% and starts jittering.
When the compare value raises above 70% the compare match interrupt is working correctly again.
Does anyone have noticed a similar issue?

I've observed this behavior in centeraligned mode too.

Thanks for yout help

This is quite abnormal. Can you refer to the DAVE4 example found at the below link.
