Features -- Counter Mode

Up/Down Counting

The Up/Down Counter Function offers two types of counting:

Up Couting (increasingly) and Down Counting (decreasingly).

Up Counting : when C0A+ and C0A- sense any input signals, the

counter counts up.

Down Counting : when C0B+ and C0B- sense any input signals, the

counter counts down. On receiving Up and Down signal

simultaneously, the counter will not perform each specific counting

accordingly, but will remain at the previous counting value, since

these simultaneous signals won't have any effect on counting

values.
