This section describes the specifics of the interrupt handling as performed in the Atmel
ATmega48/88/168. For a general explanation of the AVR interrupt handling, refer to
interrupt handling” on page
The interrupt vectors in ATmega48, ATmega88 and ATmega168 are generally the same, with
the following differences:
• Each interrupt vector occupies two instruction words in ATmega168, and one instruction word
• ATmega48 does not have a separate boot loader section. In ATmega88 and ATmega168, the
in ATmega48 and ATmega88
reset vector is affected by the BOOTRST fuse, and the interrupt vector start address is affected
by the IVSEL bit in MCUCR
