ATmega8515(L)
This section describes the specifics of the interrupt handling as performed in
ATmega8515. For a general explanation of the AVR interrupt handling, refer to “Reset
and Interrupt Handling” on page 13.
Table 22. Reset and Interrupt Vectors
Notes:
Table 23 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.

1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader
2. When the IVSEL bit in GICR is set, Interrupt Vectors will be moved to the start of the
address at reset, see “Boot Loader Support – Read-While-Write Self-Programming”
on page 166.
