3.2.1.3 Up/Down Counter
The Up/Down Counter counts the rising edges on Counter Source . The direction of the counting depends on
the signal state on Counter Aux . If Counter Aux is active (high level), the counter is increasing the counter
value; if Counter Aux is inactive (low level), the counter is decreasing the counter value.
