4.2.12 Touch Screen Connectivity (X13 and X21)

As many smaller applications need a touch screen as a user interface, different provisions are made to connect as
well 4- wire resistive touch screens as various capacitive touch screens. A touch screen can be connected either to
the dedicated touch connector X21 or to the touch signal inputs of the A/V connector X13.

The following table summarizes the different possibilities available to connect a touch screen to one of these

connectors.
