Hello , i have a really simple basic question , im using stm32f429ZI NUCLEO CART (pc14pc15 X2 cristal low ), 

 , but i connect two of my keypad pins to PH0 AND PH1 which looked on no conflict on this map 


but after making the  pcb i see that they dont work 


, i checked they looks common pins as "OSC IN OUT",


how can i close the osc so that i can use them like digital input or output ?? from cube mx or by keil code 


thanks for help
