0: The default color is used on the Base Layer.
1: The DMA channel retrieves the pixels stream from the memory.
• REP: Use Replication logic to expand RGB color to 24 bits
0: When the selected pixel depth is less than 24 bpp the pixel is shifted and least significant bits are set to 0.
1: When the selected pixel depth is less than 24 bpp the pixel is shifted and the least significant bit replicates the MSB.
