Subject: Interrupt Handler Invocation

Hi,

I am currently assuming that the ISR will be invoked repeatedly till
the ISR says the IRQ is handled.  Is it a valid assumption?
Can somebody throw some light on whether ISR is invoked repeatedly
when the ISR returns the IRQ is not handled?

What is the behaviour for edge or level triggered interrupts?
