The interrupt input configuration is shared between INT0 and INT1. Consequently, if both are used at
the same time the last configured will control the input configuration.
The table below shows how ports are mapped to the four possible pin change interrupts on ATtiny and
ATmega devices. See the description of WaitForInterrupt for more information on preparing to await a pin
change interrupt.
