Abstract

PURPOSE:To ensure the high-accuracy data transmission by counting the high or low reception level by a counter to decide the high or low level of the reception data based on the count value. CONSTITUTION:Receiver 5 receives the data and the strobe pulse; the sampling result of the data is counted by counter 12; the data is memorized in register 18; and the sampling pulse is controlled by AND gate 17. Then the received data is sampled through receiver 6 while the strobe pulse is effective. And the high or low level section of the reception data is counted by counter 12, and the high or low level is decided for the reception data based on the count value. Thus, the high-accuracy transmission is possible for the data.
