When a data request signal is inactivated while a DMA controller is executing DMA data transfer in a burst transfer mode, an address at this time is held and a remaining number of transfer times is counted. After the DMA data transfer in the burst transfer mode is finished, the address and the remaining number of transfer times are re-set in the DMA controller and then the DMA data transfer is executed. This makes it possible to re-transfer data remaining at the timing when the data request signal is inactivated, and the DMA data transfer using the burst transfer mode is executed to or from a module requesting the DMA data transfer by using level of the data request signal.
