Interrupts

The external interrupt event generates an interrupt if the corresponding configuration is
selected with DDR and OR registers and the interrupt mask in the CC register is not active
(RIM instruction).

Effect of low power modes on I/O ports
No effect on I/O ports. External interrupts cause the device to exit from WAIT mode.
