Abstract

PURPOSE: To enable to make stable operation even with the possibilities of waveform for the reception of the timing signal of transmission and reception timing signal, by simplifying the circuit constitution at the line adaptor side, with the time sharing control of concentrating the control of the transmission and reception timing.
CONSTITUTION: The register RDBUF which samples the polarity of the reception data samples the transmission timing signal ST and reception timing signal RT of a plurality of lines in time sharing manner, and holds the output only during the sampling period at the memory unit 1 corresponding to each line. Further, based on the value sampled in the register RDBUF and the content of the memory unit 1, the processing timing of the transmission and reception timing of a plurality of lines is formed in time sharing manner. That is, the control of the transmission and reception timing is centralized and the time sharing control is made, allowing to simplify the circuit constitution of the line adaptor and to operate the reception of the transmission and reception timing even with the possibility of the distrotion of waveform.
