0: The increase event will increase the duty cycle value by one in a PWM period for the corresponding channel and the
decrease event will decrease the duty cycle value by one.
1: The increase event will decrease the duty cycle value by one in a PWM period for the corresponding channel and the
decrease event will increase the duty cycle value by one.
The events are taken into account when the common timebase counter reaches its top.
If more than one CHERR register is present, CHERR0 controls channels 31-0 and CHERR1 controls channels 64-32 and so on.
