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. The most typical and general program setup for
the Reset and Interrupt Vector Addresses in ATtiny25/45/85 is shown in the program example
below.
Vector No.
