The operation of the status bits for the complete mode is shown in
Figure 12.6. The instruction is enabled by the false-to-true transition of
the rung condition. The rung would have to go false and then true after
the operation is complete in order to repeat the instruction. If the rung
remained true on subsequent scans, the instruction would not repeat. After
the instruction has operated on the last word, the done bit is set. The enable
and done bits are reset to zero and the counter is reset to position 001 when
the rung condition goes false. If the rung was enabled for only one scan,
the done bit would remain set for one scan.
