S3C2400 RISC MICROPROCESSOR
256 PALETTE USAGE( TFT )
Palette Configuration
S3C2400X01 provides 256 color palette for TFT LCD Control.
256 color palette consist of the 256(depth)
Palette supports 5:6:5(R:G:B) format and 5:5:5:1(R:G:B:I) format. When the user use 5:5:5:1 format, the intensity
data(I) is used as a common LSB bit of each RGB data. So, 5:5:5:I format is same as R(5+I):G(5+I):B(5+I) format.
For example, R(5+I)=VD[15:11]+VD[0], G(5+1)=VD[10:6]+VD[0], B(5+1)=VD[5:1]+VD[0].
The user can select 256 colors from the 64K colors through these two formats.
