1. Function availability depends on the chosen device.

2. PC13, PC14 and PC15 are supplied through the power switch. Since the switch sinks only a limited amount of current (3

mA), the use of GPIO PC13 to PC15 in output mode is limited:

- The speed should not exceed 2 MHz with a maximum load of 30 pF

- These GPIOs must not be used as current sources (e.g. to drive an LED)

After the first backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the

content of the Backup registers which is not reset by the main reset. For details on how to manage these GPIOs, refer to

the Battery backup domain and BKP register description sections in the RM0316 reference manual.

3. Fast ADC channel.

4. The VREF+ functionality is not available on the 64-pin package. In this package, the VREF+ is internally connected to

VDDA.

5. These GPIOs offer a reduced touch sensing sensitivity. It is thus recommended to use them as sampling capacitor I/O.
