ABSTRACT:
A serial bus expansion circuit, system, and method are provided. In one embodiment, the serial bus expansion circuit comprises a bus distribution circuit selectively coupling a serial bus to one of a number of serial bus outputs. The serial bus expansion circuit also includes a distribution controller having a control output coupled to a control input of the bus distribution circuit, and, a number of power-up pull resistors coupling each of the serial bus outputs to a power-up pull source.
