1. 8-bit mode

D7, D6, D5, D4, D3, D2, D1, D0: RRRRRRRR

1st write

D7, D6, D5, D4, D3, D2, D1, D0: GGGGGGGG

2nd write

D7, D6, D5, D4, D3, D2, D1, D0: BBBBBBBB

3rd write

A single pixel of data is read after the third write operation as shown, and it is written in the display RAM.

2. 16 bit mode

D15, D14, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0: RRRRRRRRGGGGGGGG

D15, D14, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0: BBBBBBBBXXXXXXXX

A single pixel of data is read after the second write operation as shown, and it is written in the display RAM.

7.1.3 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

at every gradation.

(1) 8-bit serial interface (4 line)

When entering data (parameters): A0= HIGH at the rising edge of the 8

th SCL.

When entering command: A0= LOW at the rising edge of the 8

th SCL
