2. Configure the output ports in the SIUL as required.
3. Configure the timing registers to match the TFT LCD panel in use (Section 12.4.2, TFT LCD panel
configuration”).
4. Set the background color as required.
5. Load the initial tile or palette colors into the CLUT/Tile memory
6. Configure the control descriptors for the layers and cursor that are to be used initially
7. Enable the DCU in the appropriate mode (DCU_MODE and RASTER_EN bit fields).

Vertical blanking period
A data format where the pixel values are stored using four components: Alpha, Red, Green and
Blue. DCU supports different variations of this format where different numbers of bits can be used
to represent each of the components
Part of a pixel that contains a single color (red, green or blue)
Color Look-up table. The table that contains the palette used by an indexed-color graphic
The full 18-bit value actually written to a pixel to create a color
The collection of all pixels on a panel
The set of colors that a panel can display. In most cases a panel cannot display the full gamut of
colors visible to the human eye.
An index into a table containing direct-colors. Usually smaller in size than the direct color; the DCU
provides 1, 2, 4, and 8 bits per pixel options
The list of colors used by a graphic when an indexed colors format is used. The palette is stored
in a color look up table and can be from one color up to the maximum of the size of the CLUT.
A TFT LCD containing an array of colored pixels.
The basic graphical element on a TFT LCD panel. Can display a range of colors depending on the
value of the red, green and blue values written to it. Normally arranged in a rectangular array.
A 16-entry buffer that allows writes to the DCU RAMs during the TFT LCD panel refresh period
A data format where the pixel values are stored using three components: Red, Green and Blue.
DCU supports different variations of this format where different numbers of bits can be used to
represent each of the components
A time during the TFT LCD panel refresh cycle when no data is being written to the panel
