Abstract:
1. An electronic device comprising: a serial ATA interface to transmit data to another electronic device with a serial ATA interface connected thereto via a bus; an inhibition-signal generator configured to generate an inhibition signal used to inhibit at least one of (1) in a first case in which said inhibition signal is asserted for a first preset period of time, transmission of a restoration-request signal pattern for requesting said another electronic device to restore the serial ATA interface of said another electronic device from a power-saving state to the non power-saving state, and (2) in a second case in which said inhibition signal is asserted for a second preset period of time, a reception of a power-saving request supplied from said another electronic device for requesting the serial ATA interface of said electronic device to shift to a power-saving state from a non power saving state; and an output unit configured to output a restoration-request signal pattern, to be transmitted to said another electronic device, in response to a request for restoration from a power-saving state to a non power-saving state, the request occurring in the electronic device, the output unit delaying the output of the restoration-request signal pattern until the inhibition signal is negated, when the restoration request occurs in said first preset period of time in which the inhibition signal is asserted.
