PURPOSE:To easily discriminate the newest career information, by converting a code of flag bit provided at the most significant digit of a data register storing and controlling the status information of a logical circuit and input information, and storing the result to a storage circuit. CONSTITUTION:When the designation of an address of an address register 4 is the designation of a final address, it is detected at a comparator 6 and the signal is outputted to a flag bit of the most significant digit of a data register 2. When the code is inverted, a logical device 1 detects the operation in error and when the operation of the logical device and storage of career information is stopped, the final storage career information at the storage state of the career information at a storage circuit 3 is located prior to the conversion point #n of a flag bit as shown in the DELTAmark. Thus, in outputting career information at the stop after the detection of error and analyzing mis-operation, the information at the stop can be recognized easily without referencing the content of the address register. |
