Interrupt Vectors in ATmega88A and ATmega88PA
Notes: 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 each Interrupt Vector will then be the address in this table added to the start address of the Boot Flash Section.
shows reset and Interrupt Vectors placement for the various combinations 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.
regular program code can be placed at these locations. This is also the case if the Reset Vector is in the
