Interrupt Structure
The SAB 80C515 has 12 interrupt vectors with the following vector addresses and request
flags:
Each interrupt vector can be individually enabled/disabled. The minimum response time to an
interrupt request is more than 3 machine cycles and less than 9 machine cycles.
Figure 5 shows the interrupt request sources.
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 3 or 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. Each pair can
be programmed individually to one of four priority levels by setting or clearing one bit in the
special function register IP0 and one in IP1.
Figure 6 shows the priority level structure.
