Table 12-1.
Notes:
If the program never enables an interrupt source, the Interrupt Vectors are not used, and regular
program code can be placed at these locations.
Table 12-2
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.
Table 12-2.

The most typical and general program setup for the Reset and Interrupt Vector Addresses in
ATmega16HVB/32HVB is:

1. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start of the Boot
2. When the BOOTRST Fuses are programmed, the device will jump to the Boot Loader address
