4.10.2.2.2 Table Compare Trigger
Table compare trigger differs from the linear compare trigger in
that compare points can be determined by user. That is, intervals
between compare points are variable. You may set up any four
points (P1~P4) and send triggers when motor reaches each of
them as shown in figure below.
