SOLUTION: This microprocessor is composed of a user storage means storing an application program(AP) and certification code or the like stored in a prescribed area, a storage means with built-in chip storing a key code and a central processing unit(CPU) for comparing a certification code with the certification code read from the user storage means. When the certification codes are not coincident, the AP is executed together with a means for monitoring the execution address or execution time of the AP and when the program exceeds the area or after the lapse of prescribed program execution time, the operation of the device is stopped but when the certification codes are coincident, the AP is executed. |
