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 “Reset and Interrupt
Handling” on page 10.
Table 18. Reset and Interrupt Vectors
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.
