Interrupt Vectors
ATtiny24/44/84
This section describes the specifics of the interrupt handling as performed in ATtiny24/44/84.
For a general explanation of the AVR interrupt handling, see
page
The interrupt vectors of ATtiny24/44/84 are described in
Table 9-1.
If the program never enables an interrupt source, the Interrupt Vectors are not used, and regular
program code can be placed at these locations.
The most typical and general setup for Reset and Interrupt Vector Addresses in ATtiny24/44/84
is shown in the program example below.
