Single-phase Input
For a single-phase input, the count increments when an UP pulse is input and decremented when a
DOWN pulse is input.
The count remains unchanged if UP and DOWN pulses are input simultaneously.
* Count operation for incremental counting in the CW direction.
When decremental counting in the CW direction is set, the board performs decremental counting
at the rising edges of positive pulse and incremental counting at the rising edges of negative pulses.
Single-phase Input with Gate Control
The counter can be started and stopped by using a gate control signal along with the single-phase
pulse stream.
* Count operation for incremental counting in the CW direction.
* When decremental counting in the CW direction is set, the board performs decremental counting
at the rising edges of the single-phase pulse train (phase-A/UP) while the gate control signal
(phase-B/DOWN) goes high and stops counting while the gate control signal goes low.
