6.24.4 Limitations
Due to the sharing of some I/Os of STM32MP157FAA1 by multiple peripherals, the following limitations apply in
using the PMOD button features:
The fast ADC ANA0/ANA1 and slow ADC PF12 may not be operated simultaneously with the motor
control function.
6.25 I2C_EXT connector
I2C_EXT connector MB1262/CN13 may be connected to I

C
bus daughterboard. CN13 connector pin 5 is
connected to 3V3, meaning that the external module must be compliant with 3V3.
MFX_GPIO0 of MFX MCU provides EXT_RESET.
