Abstract

A microcomputer with a motor controller circuit includes a motor controller circuit (4) which has NAND circuits (8) for producing a logical product of a rise pulse from a rise pulse generator (5) and a start level from a register (7) and flip-flop circuits (9a-9b) each responsive to start level set signals from the NAND circuits and an output pulse from a three-phase inverter waveform generator timer (6a-6b) to generate three-phase inverter waveforms.
