Figure 3.14 Cable select mode setting
Figure 3.15 shows a cable select example using a special interface cable.
This example connects CSEL of the master device to the CSEL line (conductor) of
the cable, then grounds it so that the drive recognizes that it is the master. At this
time, the CSEL conductor of the slave device is removed and cannot be connected
to CSEL of the cable, so that the drive recognizes that it is the slave.
