This section describes the specifics of the interrupt handling as performed in the Atmel
ATmega48PA/88PA/168PA. For a general explanation of the AVR interrupt handling, refer to
“Reset and Interrupt Handling” on page
The interrupt vectors in the Atmel ATmega48PA, Atmel ATmega88PA, ATmega168PA and
Atmel ATmega328/328P are generally the same, with the following differences:
• Each Interrupt Vector occupies two instruction words in Atmel ATmega168PA and Atmel
• Atmel ATmega48PA does not have a separate Boot Loader Section. In the Atmel
ATmega328/328P, and one instruction word in the Atmel ATmega48PA and Atmel
ATmega88PA.
ATmega88PA, Atmel ATmega168PA and Atmel ATmega328/328P, the Reset Vector is
affected by the BOOTRST fuse, and the Interrupt Vector start address is affected by the
IVSEL bit in MCUCR.
