ATmega48PA/88PA/168PA/328P. For a general explanation of the AVR interrupt handling, refer
to
The interrupt vectors in ATmega48PA, ATmega88PA, ATmega168PA and ATmega328P are
generally the same, with the following differences:
• Each Interrupt Vector occupies two instruction words in ATmega168PA and ATmega328P, and
• ATmega48PA does not have a separate Boot Loader Section. In ATmega88PA,
one instruction word in ATmega48PA and ATmega88PA.
ATmega168PA and ATmega328P, the Reset Vector is affected by the BOOTRST fuse, and the
Interrupt Vector start address is affected by the IVSEL bit in MCUCR.
