LCD bits per pixel
011 = 8 bpp RGB332
101 = 16 bpp RGB565
LCDBPP means the resolution (Bit Per-Pixel) of the image data which stored in memory device.
If LUTEN is enabled, LCD Controller will output data from Palette SRAM for 8bpp image. Else,
LCD Controller will treat 8bpp data as RGB332. At normally, Video Databus output is RGB888,
24bit. The other bit will be replaced with zero. Please refer to GPIO chapter to configure this
register.
The programming procedure is listed as follows:
1) Decide that the type of input raw data is YUV or RGB (
LCDCON [20]
).
2) Decide that OSD is enabled or not (
LCDCON [19]
).
3) If external panel is TFT LCD, configure TFT-related bits (
LCDCON [5:4]
and
LCDCON
[11:8]
).
4) If look-up table is needed, configure LUT-related bits (
LCDCON [18:17]
).
5) Go to Step 9.
6) If external panel is TV, configure TV-related bits (
LCDCON [7]
and
LCDCON [13:12]
).
