12. INT- Interrupts
This section describes the specifics of the interrupt handling of the device. For a general explanation of
the AVR interrupt handling, refer to the description of Reset and Interrupt Handling.
In general:
• Each Interrupt Vector occupies .
• The Reset Vector is affected by the BOOTRST fuse, and the Interrupt Vector start address is
affected by the IVSEL bit in MCUCR.
