  Well if you know how to make an interrupt program
then you know that it has to be in IM 2 to run, so to
stop the interupt program just switch back to IM 1.

   Then you might want to clear the spot you had the
interrupt at, and change back the i register to what
it was before hand, but this really shouldnt be
nessacary.
