supply operation, -2.5V ≤ V
with a 0.1µF ceramic capacitor as close to the device as possible.
Interface-Mode Select. Select serial SPI interface when SPI/UD = 1. Select serial up/down
interface when SPI/UD = 0.
Serial SPI Interface Data Input (SPI/UD = 1)
Up/Down Control Input (SPI/UD = 0). With DIN(U/D) low, a high-to-low SCLK(INC) transition
decrements the wiper position. With DIN(U/D) high, a high-to-low SCLK(INC) transition
increments the wiper position.
