PROBLEM TO BE SOLVED: To improve efficiency of data transfer in DMA transfer. SOLUTION: Tow of DMA setting register sets RS 11, RS 12 are provided, thereby the setting for the next transfer can be performed during preceeding data transfer among memories MM 11, MM 12 and an I/O interface circuit I/O 11. Accordingly, the next data transfer can be started immediately after the completion of the preceeding data transfer, so that the efficiency of the data transfer is improved.
