<p>A transmitting and receiving apparatus can correctly perform transmission and reception of data by quickly determining a signal level of a transmission and reception control signal during a period where a control line of a bus line is not driven. The apparatus includes a master device, slave devices and a bus line connecting the master device and the slave devices. The master device outputs address information identifying the slave device through the bus line. The slave device outputs a reception control signal of the level depending upon capability of data transmission/reception through a control line by driving the control line forming the bus line to the master device. The apparatus also includes level stabilizing signal generating means for outputting a level stabilizing signal to the control line, by driving the control line during a period where the slave device does not drive the control line.</p> |
