... Data written to a control Charge Pump register immediately updates the wiper position. The wipers A and B power up in midposition, D[7:0] = 80h. The MAX5392 operates as a slave device that receives data through an I interface. The interface uses a serial-data access line (SDA) and a serial-clock line (SCL) to achieve bidirec- tional communication between master(s) and slave(s) ...
