By INT1 and INT0 interruptions (if enabled), the oscillators control bits on OSCON and
CKSEL will be kept, so the selected oscillator before entering in power-down mode will
be activated. Only external interrupts INT0 and INT1 are useful to exit from power-down.
Note:
Exit from power down mode doesn’t depend on IT0 and IT1 configurations. It is only pos-
sible to exit from power down mode on a low level on these pins.
Holding the pin low restarts the oscillator but bringing the pin high completes the exit as
detailed in Figure 6. When both interrupts are enabled, the oscillator restarts as soon as
one of the two inputs is held low and power down exit will be completed when the first
input is released. In this case the higher priority interrupt service routine is executed.
Table 9 shows the state of ports during idle and power-down modes.
