Communication control device and information processing apparatus

An information processing apparatus comprising:

• a first processing unit that converts an electrical signal received by a communication channel into digital data and outputs the digital data, and in a second operation mode in which an amount of power supplied to the communication control device is lower than in a first operation mode, outputs a notification signal upon receiving an electrical signal indicating an arrival of packet data by the communication channel;
• a clock controller that, in the second operation mode, initiates supplying a clock signal upon receiving the notification signal;
• a second processing unit that (i) has a receiving unit that extracts packet data from the digital data output by the first processing unit and outputs the extracted packet data, and (ii) in the second operation mode, stops receiving packet data during a time that the clock signal is not supplied from the clock controller, and upon reception of the clock signal from the clock controller, starts receiving packet data using the received clock signal;
• a setting unit that sets an operation mode to one of the first operation mode and the second operation mode;
• and
• an execution unit that, when the first operation mode is set, executes processing using packet data received by the receiving unit.
