Register 13: PWM0 Interrupt Enable (PWM0INTEN), offset 0x044
Register 14: PWM1 Interrupt Enable (PWM1INTEN), offset 0x084
Register 15: PWM2 Interrupt Enable (PWM2INTEN), offset 0x0C4
These registers control the interrupt generation capabilities of the PWM generators (PWM0INTEN
controls the PWM generator 0 block, and so on). The events that can cause an interrupt are:
Any combination of these events can generate either an interrupt.

Description
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.
When 1, an interrupt occurs when the counter matches the
comparator B value and the counter is counting up.
When 1, an interrupt occurs when the counter matches the
comparator A value and the counter is counting down.
When 1, an interrupt occurs when the counter matches the
comparator A value and the counter is counting up.
When 1, an interrupt occurs when the counter matches the
PWMnLOAD register.
When 1, an interrupt occurs when the counter is 0.
