7.2.2.10 Object 20A6h: Latch position 1, positive or negative edge
This object is used to output the position or a time, depending on CAP0.MODE, at which the first positive or neg-
ative edge occurred on a signal, which can be configured with the command CAP0.TRIGGER.
The latch enable must be active for that purpose (see object 20A4 and 20A5).
