PURPOSE:To inexpensively and promptly control a pulse width modulating (PWM) signal without separately providing an exclusive LSI by combining and operating a microservice processing and a pulse control processing. CONSTITUTION:When an interruption requiring signal 102 and an interruptive processing format designating signal 103 inputted from an interruption control unit 9, which controls priority by receiving an input/output required signal 101, to an execution control unit 4 are both at a logic '1', the execution of a program is temporarily stopped, a save processing is not executed while the contents of a program status word 3 and a program counter 5 are being held, and the data are transferred between a peripheral device and a RAM 7 by the content of the specified address on the set RAM 7. Such a microservice processing unit and a pulse control unit 8 to output the PWM signal are combined and used. Thus the input/output processing is executed at high speed. |
