For what it's worth....
I have provision for 8 Vectored Priority
Interrupts; with individual Mask; and a common Enable/Disable. An
interrupt functions exactly the same as an JST (Jump & Store Return)
Instruction. The interrupt does its necessary processing, and waits for an
Instruction Fetch before making the Break. I use 8 pairs of dedicated
addresses (hard wired). I have used this implementation in other designs
and have never had the software people complain. After all, what I do is
hope to make things easier for the Software guys -
never jam things down their throat without proper
consultation.
