PROBLEM TO BE SOLVED: To provide a data transfer control device capable of suppressing power consumption in a plurality of interfaces when it transmits or receives data from an external device connected to it via the plurality of interfaces.SOLUTION: A data transfer control device 1 includes a transfer control section 2 that holds transfer data 101 in a buffer 5 in response to reception of a data transfer start command via a first communication section 3, transmits, via the first communication section 3, a data transfer period T1 when the transfer data is transmitted or received, and transmits, via the second communication section 4, the data transfer start command and the held transfer data. The first communication section 3 shifts from a steady state to a power-saving state on the basis of the data transfer period T1, and shifts from the power-saving state to the steady state after a lapse of the data transfer period T1. |
