2.1.1 Raster Controller

The Raster Controller provides a synchronous LCD interface. The Raster controller supports a wide variety of monochrome and full-color display types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale/serializer. Graphics data is processed and stored in the frame buffer. A frame buffer is a contiguous memory block in the system.

The Raster controller should be used if the display panel does not have its own frame buffer nor its own controller. In this mode, the MCU is responsible for sending pixels to the display directly.

Note: When using the LCD controller with EPI to interface to external memory, the external code address space 0x1000_0000 must be selected by programming the ECADR field to 0x1 in the EPI Address Map (EPIADDRMAP) register at EPI offset 0x01C.

Figure 2-2 shows the various modes and interfaces the TM4C129 MCU Raster Controller supports. The Active TFT Color RGB interface can be supported when the RASTERCTRL[9,7,1] register is programmed with x10.
