Figure 3.14 Cable selection mode setting
Figure 3.15 shows an example of cable selection with the special interface cable.
In the figure, master CSEL is connected to the cable-side CSEL line (conductor)
and then connected to GND. By this, the master drive detects itself as a master.
At the same time, the slave device detects itself as a slave because the conductor
of slave CSEL is removed and slave CSEL has no connection to cable-side CSEL.
