ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P [DATASHEET]
8285E–AVR–02/2013
Table 12-2 on page 52 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 reg-
ular 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 sec-
tion or vice versa.
Note:
1. The Boot Reset Address is shown in Table 26-6 on page 252. For the BOOTRST Fuse “1” means unprogrammed
while “0” means programmed.
The most typical and general program setup for the Reset and Interrupt Vector Addresses in Atmel
ATmega165A/165PA is:
