ATtiny20
This section describes the specifics of the interrupt handling as performed in ATtiny20. For a
general explanation of the AVR interrupt handling, see
11.
The interrupt vectors of ATtiny20 are described in
Table 9-1.
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.
