ATtiny24A/44A/84A. For a general explanation of the AVR interrupt handling, see
Interrupt Handling” on page
The interrupt vectors of ATtiny24A/44A/84A are described in
Table 9-1.
In case the program never enables an interrupt source, the Interrupt Vectors will not be used
and, consequently, regular program code can be placed at these locations.
The most typical and general setup for interrupt vector addresses in ATtiny24A/44A/84A is
shown in the program example below.
