Some applications will require a different type of action at each preset. It is possible for the
interrupt routine to distinguish one preset event from another, by turning on a unique output
for each equal relay contact SPxxx. We can determine the source of the interrupt by
examining the equal relay contacts individually, as well as X2. The X2 contact will be on
(inside the interrupt routine only) if the interrupt was caused by the external reset, X2 input.
