PURPOSE:To reduce the number of signal lines by simplifying the constitution of a receiving section without the need of a start bit detecting circuit and a counter, in transferring a code representing one character. CONSTITUTION:A data adding a start bit and a stop bit of the same sign before and after the bit string constituting a character code transmitted from a data transmission section is stored sequentially in a register SR by controlling the shift register SR with a clock transmitted from a data transmission. The receiving of one character code is detected by the logical product of outputs from the position of the register SR where the start bit and the stop bit are to be stored at the end of one character code receiving and the receiving data stored in the register SR is extracted. |
