Actually, it depends entirely on how long it takes to execute your Interupt Handler code. If you keep triggering interupts before the last one finished, you end up interupting the interupt. Do this too many times and you blow the stack and the thing crashes.

So, the REAL question is: How much time has IFI given us to service an interupt without blowing up their code?
