1. Function availability depends on the chosen device.

2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 and

PI8 in output mode is limited:

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

- These I/Os must not be used as a current source (e.g. to drive an LED).

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).

4. ULPI signals not available on the STM32F723xx devices.

5. If the device is in regulator OFF/internal reset ON mode (BYPASS_REG pin is set to VDD), then PA0 is used as an internal reset (active low).
