Patent ID: 8832347

Claim:
An automatic serial signal detecting and transceiving device operable to be interfaced with inter-integrated circuit (I 2 C) and serial general purpose input/output (SGPIO) busses, and operable to automatically detect whether a connected initiator unit is using an I 2 C interface protocol or an SGPIO interface protocol, the automatic detection device comprising: an input interface configured for electrical connection to the initiator unit, the input interface comprising a load pin that is configured to be electrically connected to an SLoad signal line of an SGPIO bus, which load pin is also configured to be electrically connected to a Reset signal line of an I 2 C bus; and a control unit, electrically connected to the input interface, configured to detect which of the I 2 C and SGPIO interface protocols a connected initiator unit is using according to a trigger signal received by the load pin, and further configured to transceive a data signal of the initiator unit according to the detected interface protocol, wherein the control unit is configured, upon completion of a data transfer using the SGPIO interface protocol, to again detect which of the I 2 C and SGPIO interface protocols a connected initiator unit is using.
