PROBLEM TO BE SOLVED: To realize power saving while ensuring convenience of return to a normal operation state from a power saving state.SOLUTION: This invention provides a data processing apparatus that includes an interface for communicating with peripheral devices, and operates in a first power mode and a second power mode in which power consumption is lower than that of the first power mode. In the data processing apparatus, when a power mode is shifted from the first power mode to the second power mode, control is performed such that power is fed to a determined interface. |
