If the parallel interface is selected, there are two different interface types; either 6800 or
8080 style. See datasheet for details about timing and how the different control signals are
used.

If a serial interface is used, see the datasheet for details about timing and how the different
control signals are used. Note that maximum clock frequency is 13 MHz.
2.3 On-board touch screen Controller, display version 2
The touch screen controller used is TSC2046 from Texas Instruments. This chip has a SPI
interface and shares the SI, SO, SCK pins in the main interface connector, with the LCD
controller. Pin 45 must however be low (TSC2046 chip CS#) in order to communicate with
the touch screen controller. See TSC2046 datasheet for details about the serial interface.
2.4 On-board LCD Controller, display version 1
The display has an embedded controller, IS2102B from ISRON. This controller chip has 1.3
Mbit embedded display RAM, which is enough for storing a complete 320xRGBx240
picture with 18 bit color depth.
There are a couple of interface alternatives to this controller. Either 16-bit or 8-bit parallel
interface or a serial interface. There are 6 pins that are used to configure the interface. The
table below lists the different options. L is statically tied to low logic level and H is statically
tied to high logic level.
