Table 23. Reset and Interrupt Vectors (Continued)
Notes:
Table 24 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.

The Boot Reset Address is shown in Table 112 on page 286. For the BOOTRST fuse “1”
means unprogrammed while “0” means programmed.
