External Interrupts
Low Level Interrupt
The External Interrupts are triggered by the INT0 or INT1 pin or any of the PCINT15:0 pins.
Observe that, if enabled, the interrupts will trigger even if the INT0, INT1 or PCINT15:0 pins are
configured as outputs. This feature provides a way of generating a software interrupt. Pin
change interrupts PCI will trigger if any enabled PCINT15:0 pin toggles. The PCMSK Register
control which pins contribute to the pin change interrupts. Pin change interrupts on PCINT15:0
are detected asynchronously. This implies 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
set up as indicated in the specification for the MCU Control Register – MCUCR. When the INT0
interrupt is enabled and is configured as level triggered, the interrupt will trigger as long as the
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
A low level interrupt on INT0 is detected asynchronously. This means that the interrupt source
can be used for waking the part also from sleep modes other than Idle (the I/O clock is halted in
all sleep modes except Idle).
Note that if a level triggered interrupt is used for wake-up from Power-down, the required level
must be held long enough for the MCU to complete the wake-up to trigger the level interrupt. If
the level disappears before the end of the Start-up Time, the MCU will still wake up, but no inter-
