6.15.6 IO restriction to other features

Due to the share of some IO of STM32MP157xAA3 by multiple peripherals, the following limitations apply in using

the audio features:

The SAI AUDIO CODEC must not be operated simultaneously with expansion connector MB1262/CN21.

The MEMS DFSDM must not be operated simultaneously with DFSDM of EXT MEMS module MB1262/CN8.

6.16 DSI LCD

Through the MB1262/CN19 connector, a DSI LCD mounted on a daughterboard MB1230 is provided. MB1230 is

a 5.5" TFT 720*1280 pixels with LED backlight, MIPI

DSI interface and capacitive touch panel based on

RK055AHD042-CT module embedding the LCD driver IC RM68200 and a touch screen controller GT9147.

3V3 and VIN supply MB1230:

• 3V3: for the LCD module (VDD_LCD and VIO_LCD) and Touch screen

• VIN: for the LED backlight of the LCD

6.16.1 DSI LCD interface

MB1230 is connected to the STM32MP157xAA3 through the DSI interface, I2C to control the GT9147, and

LCD_BL_CTRL. LCD_INT signal is connected to MFX.

The I2C is I2C2 that is shared with all the peripherals: audio codec, MFX, RGB LTDC, camera, and USB hub. The

GT9147 I

C address is 0xBB.

Table 23 describes the IO configuration for the LCD interface.
