ATtiny26(L)
Interrupts
Interrupt Vectors
The ATtiny26(L) provides eleven interrupt sources. These interrupts and the separate Reset
Vector, each have a separate program vector in the program memory space. All the interrupts
are assigned individual enable bits which must be set (one) together with the I-bit in the Status
Register in order to enable the interrupt.
The lowest addresses in the program memory space are automatically defined as the Reset and
Interrupt vectors. The complete list of vectors is shown in Table 29. The list also determines the
priority levels of the different interrupts. The lower the address the higher is the priority level.
RESET has the highest priority, and next is INT0 – the External Interrupt Request 0 etc.
The most typical and general program setup for the Reset and Interrupt Vector Addresses are:
