Rung 4:1
➀
Keeps track of the hole number that is being drilled and loads the
correct HSC preset based on the hole count. This rung is only active
when the ”hole selector switch” is in the ”3-hole” position. The
sequencer uses step 0 as a null step upon reset. It uses the last
step as a ”go forever” in anticipation of the ”end of manual” hard
wired external reset.
