Interrupt Vectors
ATtiny13
This section describes the specifics of the interrupt handling as performed in ATtiny13. For a
general explanation of the AVR interrupt handling, refer to
page
The interrupt vectors of ATtiny13 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
ATtiny13 is:
Vector No.
