Interrupt Vectors
ATtiny261/461/861
This section describes the specifics of the interrupt handling as performed in ATtiny261/461/861.
For a general explanation of the AVR interrupt handling, refer to
on page
Interrupt vectors of ATtiny261/461/861 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 program setup for the Reset and Interrupt Vector Addresses in
ATtiny261/461/861 is shown in the program example below.
