FUNCTION

1

INC

Increment/Decrement Wiper Control. When INC transitions from high-to-low, the wiper moves in the

direction established by the state of the U/D pin.

Up/Down Control. Sets the directions of wiper movement. When set to a high state, a high-to-low

2

U/D

transition on the INC pin increments the wiper. When set to a low state, a high-to-low transition on the

INC pin decrements the wiper.

L

Low-End Terminal of the Potentiometer

7

CS

Chip Select. When set to a low state, the wiper position can be adjusted using U/D and INC. When in

a high-state, activity on INC and U/D does not affect or change the wiper position.
