By connecting the CSEL of the master device to the CSEL Line (conductor) of the cable and
connecting it to ground further, the CSEL is set to low level. The device is identified as a master
device. At this time, the CSEL of the slave device does not have a conductor. Thus, since the
slave device is not connected to the CSEL conductor, the CSEL is set to high level. The device is
identified as a slave device.
