A receiving circuit includes: a terminating resistor to set a terminating level of a transmission line for transmitting a reception signal including a signal having a first level indicating a preamble; a detection circuit to detect whether a level of the transmission line is the first level or a second level; and an adjustment circuit to adjust a resistance of the terminating resistor, the adjustment circuit adjusting the resistance of the terminating resistor to a value such that the detection circuit detects the level of the transmission line as the second level when a data request is output to a transmitting side.
