External Interrupts
The External Interrupts are triggered by the INT0 and INT1 pins or any of the PCINT27..0 pins.
Observe that, if enabled, the interrupts will trigger even if the INT0 and INT1 or PCINT27..0 pins
are configured as outputs. This feature provides a way of generating a software interrupt, as
follows.
The PCMSK3, PCMSK2, PCMSK1 and PCMSK0 registers control which pins contribute to the
pin change interrupts. Pin change interrupts on PCINT27..0 are detected asynchronously. This
means that these interrupts can be used for waking the part also from sleep modes other than
Idle mode.
The INT0 and INT1 interrupts can be triggered by a falling or rising edge, or a low level. This is
configured as described in
INT0 or INT1 interrupts are enabled and are configured as level triggered, the interrupts will trig-
ger as long as the corresponding pin is held low. Note that recognition of falling or rising edge
interrupts on INT0 or INT1 requires the presence of an I/O clock, described in
and their Distribution” on page
• Pin Change Interrupt PCI3 triggers if a pin in PCINT27..24 is toggled while enabled
• Pin Change Interrupt PCI2 triggers if a pin in PCINT23..16 is toggled while enabled
• Pin Change Interrupt PCI1 triggers if a pin in PCINT15..8 is toggled while enabled
• Pin Change Interrupt PCI0 triggers if a pin in PCINT7..0 is toggled while enabled
