Abstract
A sensor includes a control circuit set to a first operation mode in which an operation is prepared by receiving a clock signal from a processor and receiving an operation command from the processor. The sensor is configured to generate a first signal including a result of an operation corresponding to the operation command and a second signal indicating completion of the operation. An interface circuit is configured to transmit the first signal and the second signal to the processor. The control circuit is set to a second operation mode due to blocking of the clock signal by a control of the processor in response to the transmission of the second signal.
