PROBLEM TO BE SOLVED: To provide a microprocessor at a low cost, which has a function to control a generator such as a stepping motor and the like with differential pulse width modulation(PWM). SOLUTION: The generator is provided with a microprocessor 1 which has at least one normal pulse width modulation(PWM) output 2, two circuits 10, 20, which respectively have at least two output terminals 11, 12 and 21, 22, which are normally connected to the PWM output 2 of the microprocessor 1 through an input, and the outputs 11, 12 and 21, 22 are normally made to correspond to the PWM output 2 of the microprocessor 1 and a reversal means B for the output terminals 11, 12 and 21, 22 disposed in each circuit 10, 20. |
