Abstract: A fast serial interface including a three-wire network connection between a bus controller and one or more bus devices is disclosed. The bus controller processes and issues data packets across the three-wire network that include a command code, a bus device selection code, and a bus device register selection code. If the command code corresponds to write code, then the selected bus device stores the data contained within the packet in the selected register. If the command code corresponds to a read command, the selected bus device retrieves the data stored in the selected register, forms a read data packet and transfers the read data packet to the bus controller.
