Abstract

PURPOSE: To eliminate the inconvenience caused by the simplification of the control system and then realize a communication system having a high process efficiency, by adding the significant process data to the CPU in the communication system in which the communication control unit formed mainly with the microprocessor is connected to the CPU.
CONSTITUTION: The CPU1 is discriminated from the microprocessor CCU4 by the 1-dot chain line l, and the CCU4 is mainly composed of the microprocessor MPU5. The transmission/reception of the data is carried out by designating either one of the circuits 3 via the CPU1 and then starting the CCU4 after designating the transmission or the reception. Thus the program of the ROM6 is executed when the MPU5 is started, and then the MPU address signal is applied to the input/output instruction decoder 17. And the control output Pi is delivered. In such way, the inconvenience caused by the simplification of the system can be prevented by adding the significant data to the CPU1. Thus a communication system can be realized with a high process efficiency.
