Note:

When the device type is set by the jumper on the device, the device should not be configured for cable selection.

(2) Cable Select (CSEL)

In Cable Select mode, the device can be configured either master device or slave device. For use of Cable Select function, Unique interface cable is needed.

CSEL connected to the interface cable selection can be done by the special interface cable.

Figure 3.16 Jumper setting of Cable Select

Figures 3.17 and 3.18 show examples of cable selection using unique interface cables.

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.
