Table 26 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 loca-
tions. 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 26. Reset and Interrupt Vectors Placement
Note:
The most typical and general program setup for the Reset and Interrupt Vector
Addresses in ATmega162 is:
