PURPOSE:To shorten the processing time of a processor by storing phase exciting time information and current indication information as set information in a memory so as to read out them by one command. CONSTITUTION:Current indication information and phase exciting time information of information necessary to control a pulse motor 18 are stored as a set in a memory ROM 12. An MPU 11 decodes by a decoder 21 set information P read out from the ROM 12, and simultaneously sets exciting time information (t) obtained at this time to a timer 13 and current indication information (i) corresponding thereto to a latch 14. Thus, since the MPU 11 can transmit data by one accessing to a bus and does not necessarily calculate it, a processing time can be shortened. |
