Interrupt Vectors in ATtiny25/45/85
ATtiny25/45/85
This section describes the specifics of the interrupt handling as performed in ATtiny25/45/85.
For a general explanation of the AVR interrupt handling, refer to
on page
The interrupt vectors of ATtiny25/45/85 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.
Vector No.
