Configure the desired I/O as output or input in the GPIOx_MODER register.

Peripheral alternate function

For the ADC, configure the desired I/O as analog in the GPIOx_MODER register.

For other peripherals:

Configure the I/O pin used to output the Cortex

connecting it to AF15

Please refer to the "Alternate function mapping" table in the datasheets for the detailed

mapping of the system and peripherals' alternate function I/O pins.
