2466T–AVR–07/10
This section describes the specifics of the interrupt handling as performed in ATmega16. 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.

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.
