Interrupt Vectors
ATtiny2313A/4313
This section describes the specifics of the interrupt handling as performed in ATtiny2313A/4313.
For a general explanation of the AVR interrupt handling, refer to
on page
The interrupt vectors of ATtiny2313A/4313 are described in
Table 9-1.
In case the program never enables an interrupt source, the Interrupt Vectors will not be used
and, consequently, regular program code can be placed at these locations.
Vector No.
