Abstract

PURPOSE:To perform the communication control many in the number of line allocation, by turning on the next bit stop instruction signal when the control circuit transmits or receives the bit before the stop bit, and restricting the transfer of the start bit with the buffer circuit through the reception of this. CONSTITUTION:The buffer circuit buffers the bit data received from the serial start-stop type line or the transmission bit data, transmits and receives it with the serial start-stop type line, and the control circuit 105 assembles the character of the transmission bit data or decomposes the transmission character data into bit data. Further, the circuit 105 turns on the next bit stop bit instruction signal when the bit prior to the stop bit is transmitted or received, and the transmission and reception of data is made by restriction of the buffer circuit receiving this without the consciousness of the start and stop bit by the control circuit 105. Thus, the communication control many in the number of line allocation can be achieved.
