Description

No effect on I/O ports. External interrupts

cause the device to exit from WAIT mode.

No effect on I/O ports. External interrupts

cause the device to exit from HALT mode.

8.5 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).
