Abstract

PURPOSE:To decrease the number of data lines for transmission and receiving, by sending out a data by use of the same line as time division, and providing a line sending out a synchronizing bit together with this data respectively, to transmit and receive the data. CONSTITUTION:To data lines (a)-(n), the first data is sent out, and also to a synchronizing line Y, a synchronizing clock data is sent out. Also, to resistances FF a1-n1 of a receiving side device 2, the first data is set. Subsequently, when the second data is sent out to the data lines (a)-(n) by a device 1, the synchronizing clock data is sent out to a synchronizing line X, and resistances FF a2-n2 of the receiving side device 2 are set. In the same way, in case when a data is sent out to the device 1 from the device 2, lines X' and Y' are processed as a synchronizing line. Subsequently, a data is sent twice to the receiving part of the other device from the transmission part of the device 1 or the device 2, and the data receiving part connects 2 pieces of resistances FF to one data line and connects each synchronizing line to other resistance.
