CONVERSION OF COMMUNICATION PROTOCOL ON A UNIFIL BUS

摘要

A method of transmission-reception over a serial bus placed, when idle, in a first state at a first voltage, including: a transmit circuit capable of coding a transmission according to a first protocol in which the respective states of the bits are conditioned by time periods of fixed levels, indifferently in the first state or in a second state at a second voltage smaller than the first one; a receive circuit capable of interpreting a communication according to the first protocol; and a protocol converter, interposed between the bus and the transmit and receive circuits, to convert the signals to be transmitted to a second protocol in which the respective states of the bits are conditioned by respective time periods of fixed levels in the first state, and to convert the received signals from the second protocol to the first protocol.
