ATmega8HVA/16HVA. For a general explanation of the AVR interrupt handling, refer to
and Interrupt Handling” on page
.
Table 12-1.
If the program never enables an interrupt source, the Interrupt Vectors are not used, and regular
program code can be placed at these locations.
The most typical and general program setup for the Reset and Interrupt Vector Addresses in
ATmega8HVA is:
Vector
No.
