PROBLEM TO BE SOLVED: To provide a motor drive circuit capable of stably and easily driving a motor even if a constant speed is maintained long, while retaining the motor drive circuit by less interposing a CPU. SOLUTION: In the motor drive circuit, pulse width data are sequentially read from a memory by means of DMA by inputting a first start signal, and pulse widths corresponding to the read pulse width data are sequentially generated. The motor drive circuit is provided with a second start signal input means, thus starting to form a deceleration region by inputting the second start signal. COPYRIGHT: (C)2004,JPO |
