Chip-Select Input. Drive low to change wiper position (W) through INC and U/D. A low-to-
high transition with INC high stores the wiper position in nonvolatile memory.
Ground
Up/Down Control Input. With U/D low, a high-to-low INC transition decrements the wiper
position. With U/D high, a high-to-low INC transition increments the wiper position.
Wiper Increment Control Input. With CS low, the wiper position moves in the direction
determined by the state of U/D on a high-to-low transition.
High Terminal of Resistor. The voltage at H can be greater than or less than the voltage at L.
Current can flow into or out of H.
