    • PURPOSE:To surely detect interruption whether it is caused by a noise, etc., or produced by a proper interrupt signal, by discriminating the state of an interruption requesting FF at the beginning of the interruption processing. CONSTITUTION:When a signal inpressed upon an interruption input terminal INT becomes '0' due to a noise, '1' is again impressed upon the terminal INT during a waiting time T, since the time T is set in a microcomputer 1 by means of a timer. Therefore, both an output terminal A1 and the input terminal INT become '0' and the fall is detected by a detecting circuit 2. After the fall is detected, an interruption requesting FF 3 is set. Therefore, an interruption requesting signal INTREQ is discriminated as '1' and the signal impressed upon the input terminal INT is discriminated as a noise, and the successive interruption processing program is not executed, but a prescribed instruction is executed and the FF 3 is reset. Furthermore, an interruption permitting FF 9 is set by means of a set instruction and operations are returned to the original program.

    • PURPOSE:To attain the collection of data even in case of fault mode and also to secure the continuation of processing again at and after a stop time point, by providing both master and slave microprograms and running these programs with an unconditional branch instruction. CONSTITUTION:A microinstruction store memory 20 of a P-ROM is divided into a master microprogram 21 and a slave microprogram 22. A fault occurs during execution of the program 21 and an interruption is produced since the collection of data is needed for confirmation of data. In such a case, the processing is discontinued and a jump instruction for unconditional branch is set to an instruction holding register 23. Thus the program 22 is read out for readout of desired data. Then the jump instruction for unconditional branch is set to the register 23 to reset the program 21. Then the program 21 is started again. Thus the collection of data is possible even in a fault mode and furthermore the processing can be continued again at and after the stop time point by providing both programs 21 and 22 and run with an unconditional instruction.
