NMI
The External Interrupt and keypad scan pins are multiplexed with PIO lines. To act as external
interrupts, these pins must be configured as inputs pins by the PIO controller. It is also possible
to trigger the interrupt by driving these pins from registers in the PIO controller, or another
peripheral output connected to the same pin.
All interrupts are available in every sleep mode. However, in sleep modes where the clock is
stopped, asynchronous interrupts must be selected.
The external interrupt lines are connected to internal sources of the interrupt controller. Using
the external interrutps requires the interrupt controller to be programmed first.
Using the Non-Maskable Interrupt does not require the interrupt controller to be programmed.
