Overview
Interrupt Vectors
ATmega16A
This section describes the specifics of the interrupt handling as performed in ATmega16A. For a
general explanation of the AVR interrupt handling, refer to
page
Table 11-1.
Notes:
Table 11-2
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
Vector No.

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
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.
