PWM#05

Generator load with global sync may lead to erroneous pulse width

Description

There is a condition where the generator timer may still count with the old value, but the new comparator value gets loaded causing an erroneous high pulse width.

Workaround

The application must use the interrupt status to write the value of the new load and comparator values. When using the down count mode, clear the raw interrupt status bit for the respective comparator down count match interrupt status bit, wait for it to be set again and then update the new value for the load and comparator match.
