Abstract
A serial communication system is provided which performs serial communication between host and slave apparatus using half-duplex channel communication with a serial data signal generated by superimposing a data signal on a clock signal. The host apparatus transmits through a transmission path an identification signal generated by superimposing on the clock signal identification data for specifying a slave apparatus to be requested, after transmitting through the transmission path a preamble signal generated by superimposing successively repeated data on the clock signal.
