(2) 4096 color display
(2-1) Type 4096 color display
1
8-bit mode
D7, D6, D5, D4, D3, D2, D1, D0: RRRRGGGG (8 bits) 1st write
D7, D6, D5, D4, D3, D2, D1, D0: BBBBRRRR (8 bits) 2nd write
D7, D6, D5, D4, D3, D2, D1, D0: GGGGBBBB (8 bits) 3rd write
Data is acquired through write operations as shown above and then that of two pixels is written to the display RAM.
2
16-bit mode
D15, D14, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0: RRRRGGGGBBBBXXXX (12 bits)
Data is acquired through single write operation and then written to the display RAM.
“XXXX” are dummy bits, and they are ignored for display.
(2-2) Type B 4096 color display
1
8-bit mode
D7, D6, D5, D4, D3, D2, D1, D0: XXXXRRRR (4 bits) 1st write
D7, D6, D5, D4, D3, D2, D1, D0: GGGGBBBB (8 bits) 2nd write
A single pixel of data is read after the second write operation as shown, and it is written in the display RAM.
“XXXX” are dummy bits, and they are ignored for display.

16-bit mode
D15, D14, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0: XXXXRRRRGGGGBBBB (12 bits)
A single pixel of data is read and written in the display RAM in a single write operation.
“XXXX” are dummy bits, and they are ignored for display.
8.1.3 8- and 9-bit Serial Interface
The 8-bit serial interface uses four pins - CS, SI, SCL and A0 - to enter commands and data. Meanwhile, the 9-bit serial
interface uses three pins - CS, SI and SCL - for the same purpose.
Data read is not available with the serial interface. Data entered must be 8 bits. Refer to the following chart for entering
commands, parameters or gray-scale data.
The relation between gray-scale data and data bus in the serial input is the same as that in the 8-bit parallel interface
mode (described in the preceding section) at every gradation.
(1) 8-bit serial interface
When entering data (parameters): A0 = HIGH at the rising edge of the 8th SCL.
When entering command: A0 = LOW at the rising edge of the 8th SCL.
