Dear Steve,

I would like to know more about interrupts as they often interrupt my projects progress :)

What if an interrupt service routine is being served (after an interrupt has occured) and before it completes (by reaching RETI) the interrupt again occurs. Lets take external interrupt 0 for example.

Will the service rountine be interrupted half way ?

or

interrupt will not occur before the service routine has completed ?

I tried to get an explanation in the book but could not get much.
