Register 16: PWM0 Interrupt and Trigger Enable (PWM0INTEN), offset 0x044
Register 17: PWM1 Interrupt and Trigger Enable (PWM1INTEN), offset 0x084
Register 18: PWM2 Interrupt and Trigger Enable (PWM2INTEN), offset 0x0C4
Register 19: PWM3 Interrupt and Trigger Enable (PWM3INTEN), offset 0x104
These registers control the interrupt and ADC trigger generation capabilities of the PWM generators
(PWM0INTEN controls the PWM generator 0 block, and so on). The events that can cause an
interrupt,or an ADC trigger are:
(PWM0INTEN controls the PWM generator 0 block, and so on). The events that can cause an
interrupt,or an ADC trigger are:
■ The counter being equal to the load register
■ The counter being equal to zero
■ The counter being equal to the PWMnCMPA register while counting up
■ The counter being equal to the PWMnCMPA register while counting down
■ The counter being equal to the PWMnCMPB register while counting up
■ The counter being equal to the PWMnCMPB register while counting down
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. The PWMnRIS register provides information about which events have caused raw
interrupts.

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.
