Abstract
A data communication apparatus for performing communication of data with a master device via a bus includes a clock control signal generation circuit that outputs a clock control signal corresponding to a reset state and a communication state of the data communication apparatus, a communication start detection circuit that detects a start of communication on the basis of a clock signal on the bus and the data, a clock generation circuit that generates an internal clock signal on the basis of the clock signal on the bus, and a data processing control circuit that receives the internal clock signal and controls communication of the data with the master device. The clock generation circuit stops generating the internal clock signal in accordance with the clock control signal, in the reset state of the data communication apparatus and in a period from release of the reset state to the start of communication.
