Interrupts
This section describes the specifics of the interrupt handling in ATtiny4/5/9/10. For a general explanation of the
9.1
Interrupt Vectors
Interrupt vectors of ATtiny4/5/9/10 are described in Table 9-1 below.
Note:
1. The ADC is available in ATtiny5/10, only.
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.
The most typical and general setup for interrupt vector addresses in ATtiny4/5/9/10 is shown in the program exam-
ple below.
