4 Period measurement CLK –
– No function
CLK Clock signal of a connected encoder
HIGH level starts and / or stops the counting process
CLK−UP Clock signal of a connected encoder
With each LOW−HIGH edge the counter counts up by 1
CLK−DOWN Clock signal of a connected encoder
With each LOW−HIGH edge the counter counts down by 1
DIR Indicates counting direction depending on signal level
LOW: Upcounter
HIGH: Downcounter
