The following rung will keep track of the hole number that is being drilled and loads the next correct DII
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". Movin ga0intoS:49tellstheDIItotrigger an interrupt when the
trailing
edge of the current book is
