Abstract
A communication apparatus includes a communication circuit, a clock supply circuit, a CPU and a memory storing a program which, when executed by the CPU, causes the communication apparatus to function as a control unit which causes the communication circuit to operate in one of a first mode in which the communication circuit performs a normal communication with the external apparatus and a second mode in which the communication circuit operates with lower power consumption than in the first mode. In the second mode, the control unit controls the clock supply circuit so as not to supply the clock signal to the communication circuit. While the communication circuit is operating in the second mode and the clock signal is not being supplied to the communication circuit, the control unit controls the clock supply circuit to start supply of the clock signal to the communication circuit in response to a predetermined signal.
