interrupt duration

I wonder, how long I have to set an interrupt. For one clock cycle, until there is some response, ... Has anyone a clue?

What do you need a shorter way of. If the signal stays on or not, will not change anything on the time needed to process the interrupt.

Or is it the following you need to know : how much cycles does it takes for the cpu itself from a high on an interrupt pin to the first instruction sitting at the nasys_execption_address??

Well, that is a thing I also wants to know.
