Abstract

PURPOSE:To transmit the same transmission message to a plurality of lines simply, by providing an information bit which indicates whether the memory storing the intermediate information for transmission/reception is to be rewritten or not, with a signal transmission/reception control memory. CONSTITUTION:A signal transmission/reception control memory 11 is provided with an information bit 11c which indicates whether a memory 12 storing the intermediate information for transmission/reception is to be rewritten or not. To execute multiplex communication function to the signal transmission/reception control memory 11, the same number is written in a signal transmission/reception set number 11a of the memory 11 so that the same signal transmission/reception section can be connected to N lines and the rewrite of the memory 12 for the N lines can be made only once.
