I am not entirely sure, because I haven't worked with it before, but according
to my reading I believe that the biggest speciality of this type of function
is that it does a return from interrupt instead of just a normal return from
subroutine. I think that it may also save off all of the registers before
entering the routine, and then restores them just before the return.

If after I get home and find out that this is not correct by consulting
the manual, I will post another article to clarify if someone has not already
done so.
