Register 11: PWM0 Interrupt and Trigger Enable (PWM0INTEN), offset 0x044
This register controls 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 if more than one is
specified.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Trigger for Counter=Comparator B Down
When 1, a trigger pulse is output when the counter matches the
comparator B value and the counter is counting down.
Trigger for Counter=Comparator B Up
When 1, a trigger pulse is output when the counter matches the
comparator B value and the counter is counting up.
Trigger for Counter=Comparator A Down
When 1, a trigger pulse is output when the counter matches the
comparator A value and the counter is counting down.
Trigger for Counter=Comparator A Up
When 1, a trigger pulse is output when the counter matches the
comparator A value and the counter is counting up.
