ATtiny48/88
This section describes the specifics of interrupt handling in ATtiny48/88. For a general explana-
tion of the AVR interrupt handling, refer to
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.
