PURPOSE:To realize stabilized driving of motor by dividing the frequency of a pulse generated from a CR oscillation circuit based on a clock pulse and setting a motor drive basic pulse based on a data obtained by converting the frequency division data. CONSTITUTION:A pulse train generated from a CR oscillation circuit 1 enters into a frequency division circuit 2 which divides the frequency based on a clock pulse 12 to produce a frequency division data. The frequency division data is fed to a data conversion circuit 3 which outputs a converted data. A pulse generating circuit 4 generates a motor drive basic pulse 10 depending on the converted data. The data conversion circuit 3 may be replaced by a ROM. |
