7.6. Display Data Format
ILI9341 supplies 18-/16-/9-/8-bit parallel MCU interface with 8080- /8080- series, 3-/4-line serial interface
and 6-/16-18-bit parallel RGB interface. The parallel MCU interface and serial interface mode can be selected by
external pins IM [3:0] and RGB interface mode can be selected by software command parameters RCM[1:0].
7.6.1. 3-line Serial Interface
The 3-line/9-bit serial bus interface of ILI9341 can be used by setting external pin as IM [3:0] to “0101” for serial
interface I or IM [3:0] to “1101” for serial interface II. The shown figure is the example of 3-line SPI interface.
