Table 10-1.
Notes:
Table 10-2
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 10-2.
Note:
The most typical and general program setup for the Reset and Interrupt Vector Addresses in
ATmega1284P is:
