ABSTRACT:
A group of address signals is constituted by a start bit followed by a predetermined number of address bits and a stop bit. A group of data signals preceding another group of data signals is constituted by a start bit followed by the same predetermined number of data bits and a stop bit. A group of data signals preceding a group of address signals is constituted by a start bit followed by the predetermined number of data bits and two stop bits. At the receiving end, as a group of signals is received, a bit corresponding to the predetermined number plus three is sensed. If the sensed bit is a start bit, the next group is processed as a group of data signals. If the sensed bit is a stop bit, the next group is processed as a group of address signals.
