Reset and Interrupt
Handling
The AT90S8515 provides 12 different interrupt sources. These interrupts and the sepa-
rate reset vector each have a separate program vector in the program memory space.
All interrupts are assigned individual enable bits that 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 2. The list
also determines the priority levels of the different interrupts. The lower the address, the
higher 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:
