STM32H745IIK6 GPIO Pxx_C pin configrations

[Ali_Arslan_]

On our custom board using STMH745IIK6 we cant use both PC3_C and PC3 pins together. PC3 is configured as ADC reading 1.7V and PC3_C is configured as SPI MISO and when configured this way we cant read SPI device (I3G4250D) also ADC reads corrupt as well. When using only ADC we can read the correct readings but still we cant read SPI device when closing the ADC port. 
Is there any way we can switch between this pins? 

Are we missing any critical points when using this pins ? 

 

Thank you,

Ali.

In order to use PC3_C as a non-analog pin, the switch between PC3 and PC3_C must be closed, which means the pins are no longer independent.

If you want them to be independent, the only thing you can use PC3_C for is the ADC.
