Interrupt Vectors in ATmega88A and ATmega88PA
1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at reset, see
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
port – Read-While-Write Self-Programming” on page
each Interrupt Vector will then be the address in this table added to the start address of the Boot Flash Section.

tions of BOOTRST and IVSEL settings. If the program never enables an interrupt source, the
Interrupt Vectors are not used, and regular program code can be placed at these locations. This
is also the case if the Reset Vector is in the Application section while the Interrupt Vectors are in
the Boot section or vice versa.
