Increment Toggling INC while CS is low moves the wiper either up or down.
Up/Down The U/D input controls the direction of the wiper movement.
The high terminal is equivalent to one of the fixed terminals of a mechanical potentiometer.
Ground
The wiper terminal is equivalent to the movable terminal of a mechanical potentiometer.
The low terminal is equivalent to one of the fixed terminals of a mechanical potentiometer.
Chip Select The device is selected when the CS input is LOW, and de-selected when CS is
high.
