Figure 17 – Display data RAM writing position for color A, B and C data input in 256 color mode
In data RAM, each data occupies 6-bit. However, color B and C have 3-bit length and color A has 2-bit
only in 256 color mode. Therefore, RAM positions B2~B0, C2~C0 and A3~A0 are empty originally.
These emptied positions are filled as shown above to increase color A, B and C to 6-bit length in display
data RAM.
