PURPOSE:To facilitate the control of a motor and prevent the generation of restriction in the transmission of data by a method wherein a register is provided with an output signal of a timing circuit as a timing signal to give and take data with a proper timing. CONSTITUTION:An access signal 26, obtained by decoding the light signal 15, an address signal 14 and a tip select signal 13 of a higher rank microprocessor through a decoder 16, is inputted into a timing circuit 18 to convert it into a proper timing. Then, data are taken into the input register 31 of a second stage, which is connected to the input data path 29 of a second stage, by the output 30 of the timing circuit 18 while the data are given to the data path 32 under processing the data. According to this method, a timing between the data on the data path 2 and a data access signal 20 is collapsed to prevent the data on the data path 2 from being not taken into the register 31. |
