Checked PF0 & PF1 in mode GPIO_IN + GPIO_PuPd_UP, when reading I get 1 & 2 if PF0 or PF1 connect to GND the signal changes to 0Port inputs not involved in the scheme

Hello. Tell me why not work I2C2 in STM32F407Z if selection PF0 & PF1 pins. In initialization all ok, when choosing PB10 & PB11 all work. The following code works with pins PB10 & PB11. Thanks.
