Rung 4:0
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 high–speed counter at each entry into the RRUN mode and
each time that the external reset signal is activated.
