摘要 <p><P>PROBLEM TO BE SOLVED: To provide an integrated circuit device, a microcomputer and electronic equipment for performing DMA division transfer by one channel without increasing hardware. <P>SOLUTION: This integrated circuit device includes a DMA transfer control register 110 and a DMA transfer control circuit 130 for dividing transfer object data into a plurality of blocks based on the value of the DMA transfer control register, and for controlling DMA transfer to be performed by block units. The DMA transfer control register 110 includes a block data size storage register 120 and an address offset register 122, and the DMA transfer control circuit 130 counts data transfer amounts, and adds an offset address based on the address offset value when the data transfer amounts reach a block data size value, and calculates the address of the transfer destination of the next block. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p>
