Abstract
A data transfer control device includes a link controller which analyzes a packet received from a host-side data transfer control device through a serial bus, and an interface circuit which generates an interface signal and outputs the generated interface signal to an interface bus. When the address automatic update mode in an address automatic update field of a packet received from the host-side data transfer control device is set to ON, the interface circuit sequentially outputs signals of automatically updated addresses and signals of L-bit-data from among K bits of data set in the packet, the L-bit-data making a pair with each of the automatically updated addresses, while performing address automatic update processing M times (K=L×(M+)) using an address set in the packet as a start address.
