Datasheet
The sequence of sending 65K color depth pixel in 8-bit MCU interface is divided into two 8-bit sessions as
shown below.
With reference to Figure 8 conventions, in writing the data into graphic display data RAM, the bit positions
filled by the input data for each color is shown below.
In data RAM, each data occupies 6-bit. However, color A and C have 5-bit length only in 65k color mode.
Therefore, RAM positions A0 and C0 are empty originally. These emptied positions are filled as shown
above to increase color A and C to 6-bit length in display data RAM.
Data access in 256 colors mode
In 256-color mode, each pixel is composed of 8-bit. Only 8-bit MCU interface is available to access
display data RAM. The communication session is done in 1 time by writing 8-bit data into RAM.

With reference to Figure 8 conventions, in writing the data into graphic display data RAM, the bit positions
filled by the input data for each color is shown below.
