1. Function availability depends on the chosen device.

2. PC13, PC14, and PC15 are supplied through the power switch (by VSW). Since the switch only sinks a limited amount of current (3 mA), the use of PC13 to PC15 GPIOs

in output mode is limited:

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

- These GPIOs must not be used as current sources (for example to drive a LED).

3. After a backup domain power-up, PC13, PC14, and PC15 operate as GPIOs. Their function depends then on the content of the RTC registers that are not reset by the

system reset. For details on how to manage these GPIOs, refer to the backup domain and RTC register descriptions in the product reference manual.

4. After reset, this pin is configured as JTAG/SWD alternate functions. The internal pull-up on PA15, PA13, PB4 pins and the internal pull-down on PA14 pin are activated.

5. Power supply is VDDIO2.
