DEFINITION
Counts the rising edges of input signal In.
INPUTS
In — A logic input signal.
Set — A logic level value that preloads the pulse counter
accumulator with the Preset value when
≠
0.
Preset — A signed integer that is preloaded into the pulse counter
accumulator when Set
≠
0.
OUTPUT
Out — A signed integer that is incremented on every rising edge of
input signal In. Out increments to the positive limit but is
not allowed to roll over.
FUNCTION
If Set is true, then Out = Preset value.
If Set is false, then Out = Out + 1 on rising edge of In.
