11. Interrupts
11.1
Overview
This section describes the specifics of the interrupt handling as performed in ATmega48/88/168.
For a general explanation of the AVR interrupt handling, refer to
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
in ATmega48 and ATmega88.
• ATmega48 does not have a separate Boot Loader Section. In ATmega88 and ATmega168, the
Reset Vector is affected by the BOOTRST fuse, and the Interrupt Vector start address is
affected by the IVSEL bit in MCUCR.
