Interrupt Structure
The SAB 80C517 has 14 interrupt vectors with the following vector addresses and request
flags.
Each interrupt vector can be individually enabled/disabled. The response time to an interrupt
request is more than 3 machine cycles and less than 9 machine cycles.
External interrupts 0 and 1 can be activated by a low-level or a negative transition (selectable)
at their corresponding input pin, external interrupts 2 and 3 can be programmed for triggering
on a negative or a positive transition. The external interrupts 2 to 6 are combined with the
corresponding alternate functions compare (output) and capture (input) on port 1.
For programming of the priority levels the interrupt vectors are combined to pairs or triples.
Each pair or triple can be programmed individually to one of four priority levels by setting or
clearing one bit in special function register IP0 and one in IP1. Figure 9 shows the interrupt
request sources, the enabling and the priority level structure.
