Control Chip, Control Method and Connection Device Utilizing the Same

摘要

A control chip including a plurality of first pins, a plurality of second pins, a plurality of third pins, a level detection unit, a determining unit and a control unit is provided. The first pins are coupled to a host device via a first connection port. The second pins are coupled to an electronic device via a second connection port. The third pins are coupled to a peripheral device via a third connection port. The level detection unit detects the first and second pins to generate a first detection result. The determining unit determines whether a portion of the first and second pins transmit data to generate a determination result. The control unit adjusts a level of a specific pin among the first and second pins according to the first detection result and the determination result.
