Abstract

PURPOSE: To ensure the confirmation even for the normalcy for the writing action or the register reading of the microprogram, by securing such circuit constitution in which the initial value setting means, the fault detecting means and the microprogram control means are included.
CONSTITUTION: The following means are provided: initial value setting means 1 which delivers initial value setting signal 11 based on initializing signal 10; fault detecting means 3 which detects the parity of the data stored in register 2; microprogram control means 4 which delivers fault display lamp lighting signal 16, writing data 14 and writing designation signal 15 in response to fault detection display signal 13 and the output data of register 2 each; and others. In such constitution, output data 12 of register 2 is read based on the designation from means 4 and in case signal 13 is "1" to be compared with the data which is precedingly written into data 2. And in case no agreement is obtained in the comparison result, it is found that some fault has occured at means 4 relating the reading or writing action, writing data bus 14, register 2, signal 15 or the bus of data 12.
