PURPOSE:To analyze the abnormality factor with high efficiency by avoiding an immediate resetting action at occurrence of the abnormality and writing the data necessary for analysis into an external memory in a key interruption process. CONSTITUTION:An interruption signal (b) is inputted to a CPU 1 via an FF 13 at occurrence of the abnormality with operation of a key 12. The CPU 1 stores the abnormality data including the present program signal state, the command information, the status information, etc., into a main memory 5. The actions of all component members including the CPU 1 are forcibly stopped when a power switch 11 is turned off. When the switch 11 is turned on again, the drive voltage Vc is supplied and the CPU 1 executes a power supply application process with a reset signal (a) and based on a program stored in a ROM 3. Then the CPU 1 reads out all storage contents of the memory 5 and saves them into an external memory 6. Then a normal program is started. In such a constitution, the abnormality factor can be analyzed with high efficiency via an abnormality releasing device. |
