8019K–AVR–11/10
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 10-2.
Note:
The most typical and general program setup for the Reset and Interrupt Vector Addresses in
ATmega165P is:
BOOTRST
