Notes from the datasheet[cite: 1]:

1. Function availability depends on the chosen device. [cite: 1]
2. PC13, PC14 and PC15 are supplied through the power switch. [cite: 1] Since the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited: [cite: 1]
   • The speed should not exceed 2 MHz with a maximum load of 30 pF. [cite: 1]
   • These I/Os must not be used as a current source (e.g. to drive an LED). [cite: 1]
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after reset (because these registers are not reset by the main reset). [cite: 1] For details on how to manage these I/Os, refer to the RTC register description sections in the STM32F411xx reference manual. [cite: 1]
4. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1). [cite: 1]
5. If the device is delivered in an UFBGA100 and the BYPASS_REG pin is set to VDD (Regulator off/internal reset ON mode), then PA0 is used as an internal Reset (active low). [cite: 1]
