1. I = input, O = output, S = supply.

2. FT = 5 V tolerant.

3. Function availability depends on the chosen device.

4. If several peripherals share the same I/O pin, to avoid conflict between these alternate functions only one peripheral should

be enabled at a time through the peripheral clock enable bit (in the corresponding RCC peripheral clock enable register).
