Open-drain D+/D- multiplexer selection control. Connect the DSEL to a logic rail via 10-KΩ resistor. The pin is normally float and pull-up by external resistor. During Input Source Type Detection , the pin drives low to indicate the device D+/D- detection is in progress and needs to take control of D+, D- signals. When detection is completed, the pin keeps low when DCP or MaxCharge is detected. The pin returns to float and pulls high by external resistor when other input source type is detected
