For the 2
MCU transmits three 16-bit words to write two 18-bit pixels data into OLED driver. Option 2 is selected
by setting A0h register A[7:6] bits to 11b. In below, A1, B1, C1 are first data pixel bits, and A2, B2, C2 are
second data pixel bits.
For 9-bit modes, the communication is divided into two sessions of 9 data bits. MCU transmits two 9 data
bits to write one 18-bit pixel data into OLED driver. This 9-bit mode can be selected by setting the A[3] bit
in command A0 to 1.
In 8-bit MCU interface, the communication session is divided into three times. MCU transmit three 8-bit
bytes to write one 18-bit pixel data into OLED driver.
Data access in 65k colors mode
Writing a 65K pixel in 16-bit MCU interface involves one session as follows.
