Interrupt Vectors
ATtiny4/5/9/10
This section describes the specifics of the interrupt handling in ATtiny4/5/9/10. For a general
explanation of the AVR interrupt handling, see
Interrupt vectors of ATtiny4/5/9/10 are described in
Table 9-1.
Note:
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 ATtiny4/5/9/10 is shown in
the program example below.
Vector No.
