Layer (n) Control Register
| LAYER_EN | Layer on. This bit enables/disables the layer. When a layer is enabled, data is fetched from the frame buffer, that is, the address, number of lines, line length and pitch settings have to be consistent. When a layer is disabled, the default color is used for all pixels. |
| CLUT_EN | CLUT lookup on. This bit enables/disables the usage of the color look-up table. If enabled, the blue component of the frame buffer pixel after conversion to the internal pixel format is used to look up a RGB value in the table. This RGB value replaces the original RGB value of that pixel. The CLUT is located before the color keying. |
| DFLT_CBLEND_EN | Default color blending enable. This bit enables blending with the default color for a layer, which is disabled or for pixels on a layer outside of the window. When default color blending is disabled, the color of the subjacent layer is simply passed through for such pixels. |
