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.
Table 11-2.
Note:
The most typical and general program setup for the Reset and Interrupt Vector Addresses in
Atmel ATmega325/3250/645/6450 is:
