Register 11: PWM0 Interrupt/Trigger Enable (PWM0INTEN), offset 0x044
This register controls the interruptThese registers control the interrupt and ADC trigger generation
capabilities of the PWM generator. The events that can cause an interrupt or an ADC trigger are:
Any combination of these events can generate either an interrupt or an ADC trigger, though no
determination can be made as to the actual event that caused an ADC trigger.

Description
Reserved bits return an indeterminate value, and should
never be changed.
When 1, a trigger pulse is output when the counter matches
the comparator B value and the counter is counting down.
When 1, a trigger pulse is output when the counter matches
the comparator B value and the counter is counting up.
When 1, a trigger pulse is output when the counter matches
the comparator A value and the counter is counting down.
When 1, a trigger pulse is output when the counter matches
the comparator A value and the counter is counting up.
When 1, a trigger pulse is output when the counter matches
the PWMnLOAD register.
When 1, a trigger pulse is output when the counter is 0.
Reserved bits return an indeterminate value, and should
never be changed.
When 1, an interrupt occurs when the counter matches the
comparator B value and the counter is counting down.
