Up/Down Control Input. With CS high, a low-to-high transition increments or decrements the wiper
position, depending on the mode.
Chip-Select Input. A low-to-high CS transition determines the mode: increment
if U/D is high, decrement if U/D is low.
Power Supply
Zero-Crossing Detection Enable Input. Set to low to enable zero-crossing detection.
