PTS A/D Scan Mode Control Block
In A/D scan mode, the PTS causes the A/D converter to perform multiple conversions on one or more
channels and then stores the results. The control block contains pointers to both the AD_RESULT
register (PTSPTR1) and a table of A/D conversion commands and results (PTSPTR2), a control
register (PTSCON), and an A/D conversion count (PTSCOUNT).
