Resets the hole count sequencers each time that the low preset is
reached. The low preset has been set to zero to cause an interrupt to
occur each time that a reset occurs. The low preset is reached
anytime that a reset C5:0 or hardware reset occurs. This ensures that
the first preset value is loaded into the HSC at each entry into the
REM Run mode and each time that the external reset signal is
activated.
