LM3S601 Microcontroller
Register 13: PWM0 Interrupt Enable (PWM0INTEN), offset 0x044
Register 14: PWM1 Interrupt Enable (PWM1INTEN), offset 0x084
Register 15: PWM2 InterruptEnable (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:
■ The counter being equal to the load register
■ The counter being equal to zero
■ The counter being equal to the comparator A register while counting up
■ The counter being equal to the comparator A register while counting down
■ The counter being equal to the comparator B register while counting up
■ The counter being equal to the comparator B register while counting down
Any combination of these events can generate either an interrupt.

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.
Interrupt for Counter=Comparator B Down
When 1, an interrupt occurs when the counter matches the comparator B
value and the counter is counting down.
Interrupt for Counter=Comparator B Up
When 1, an interrupt occurs when the counter matches the comparator B
value and the counter is counting up.
Interrupt for Counter=Comparator A Down
When 1, an interrupt occurs when the counter matches the comparator A
value and the counter is counting down.
