7. Function Description
7.1. MCU interfaces
ILI9341 provides the 8-/9-/16-/18-bit parallel system interface for 8080- /8080- series, and 3-/4-line serial
system interface for serial data input. The input system interface is selected by external pins IM [3:0] and the bit
formal per pixel color order is selected by DBI [2:0] bits of 3Ah register.
7.1.1. MCU interface selection
The selection of interface is done by setting external pins IM [3:0] as shown in the following table.
