Abstract:
A multiplex communication method for implementing multiplex communication between a plurality of circuit units, said method comprising the steps of:forming, as a format of a transmitted data signal, serial data consisting of first data, second data, and a parity, the second data having the same content as the first data, the parity indicating that a number of logical 1s or logical 0s forming the first data and the second data is even or odd; andselecting regular data in such a manner that when the transmitted data signal is received, if the first data and the second data are compared with each other and judged to be coincident with each other from the comparison, then the coincident data is selected as the regular data without checking a logic of the parity and if the first data and the second data are judged to be different from each other from the comparison, then the logic of the parity is checked and if only one of the first data or the second data corresponds to the logic of the parity, then the data corresponding to the logic of the parity is selected as the regular data, otherwise the data is discarded.
