Chip-Select Input of Resistor 1. Drive low to change wiper position W1
through INC and U/D.
Up/Down Control Input. With U/D low, a high-to-low INC transition
decrements wiper position. With U/D high, a high-to-low INC transition
increments wiper position.
Up/Down Control Input of Resistor 1. With U/D1 low, a high-to-low INC1
transition decrements wiper position W1. With U/D1 high, a high-to-low
INC1 transition increments wiper position W1.
Up/Down Control Input of Resistor 2. With U/D2 low, a high-to-low INC2
transition decrements wiper position W2. With U/D2 high, a high-to-low
INC2 transition increments wiper position W2.

Wiper Increment Control Input. With CS1 low, a high-to-low transition
increments (U/D high) or decrements (U/D low) wiper position W1. This
applies similarly for CS2 and W2.
Wiper Increment Control Input. With CS2 low, a high-to-low transition
increments (U/D2 high) or decrements (U/D2 low) wiper position W2.
Wiper Increment Control Input. With CS1 low, a high-to-low transition
increments (U/D1 high) or decrements (U/D1 low) wiper position W1.
Chip-Select Input of Resistor 2. Drive low to change wiper position W2
through INC and U/D.
