ATmega32(L)
This section describes the specifics of the interrupt handling as performed in ATmega32. For a
general explanation of the AVR interrupt handling, refer to
page
Table 18. Reset and Interrupt Vectors
Notes:
Table 19
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.

1. When the BOOTRST fuse is programmed, the device will jump to the Boot Loader address at
2. When the IVSEL bit in GICR is set, interrupt vectors will be moved to the start of the Boot
shows Reset and Interrupt Vectors placement for the various combinations of
reset, see
Flash section. The address of each Interrupt Vector will then be the address in this table added
to the start address of the Boot Flash section.
