Abstract
PURPOSE: To suitably perform the data processing, by performing the start of control data giving and reception program from the central processing section with the interruption detection and performing the start of message data giving and reception program from the communication line with the detection of scan, in the terminal control unit of microprogram control system.
CONSTITUTION: The program processing the control data giving and reception request from the microprocessor is stored in ROM(A)21 and the program processing the message data giving and reception request from the communication line is stored in ROM(B)18, and the both ROM are addressed with the same manner. At the application of power input, the selection circuit 15 activates ROM(B)18 with the set signal 14 and the message data from the communication line 112 is inputted. When the control data giving and reception request is present from the microprocessor, the selection circuit 15 selects the ROM(A)21 with the program counter selection signal 19.
