12. Interrupts
This section describes the specifics of the interrupt handling as performed in Atmel
ATmega325/3250/645/6450. For a general explanation of the AVR interrupt handling, refer to
12.1
Interrupt Vectors in Atmel ATmega325/3250/645/6450
Note:
1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at reset, see “Boot Loader Sup-
2. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start of the Boot Flash Section. The address of
each Interrupt Vector will then be the address in this table added to the start address of the Boot Flash Section.
3. PCINT2 and PCINT3 are only present in ATmega3250 and ATmega6450.
