ABSTRACT:
A microcomputer with a built-in motor control circuit comprising a PWM generating circuit capable of automatically inverting a start level of PWM output or of changing the start level according to an optional preset pattern, an interruption request control circuit for controlling an interruption timing, and a multi-function reload register, is configured such that a start level content is inverted automatically at every period by setting a variable required for the conversion at a program executed on CPU when the start level content of the PWM output is inverted at every period, so as to make the setting unnecessary at every interruption.
