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?

I'm talking about UL.

in a user component, I have a bit in a register (flipflop) which is set to generate

an interrupt (signal irq);

in the interrupt service routine, I clear this bit by writing to the irq-register of

the component;

so irq signal of the user component stays active until it&#39;s service routine is called.[/b]

Thats exactly how I do it, too. So, there is no shorter way?
