I/O PORTS (Cont’d)
11.4 LOW POWER MODES
11.5 INTERRUPTS
The external interrupt event generates an interrupt
if the corresponding configuration is selected with
DDR and OR registers and the I-bit in the CC reg-
ister is reset (RIM instruction).

Description
WAIT
No effect on I/O ports. External interrupts
cause the device to exit from Wait mode.
HALT
No effect on I/O ports. External interrupts
cause the device to exit from Halt mode.
