1. 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 RM0313 reference manual.
2. When using the small packages (48 and 64 pin packages), the GPIO pins which are not present on these packages, must not
be configured in analog mode.
3. these pins are powered by VDDSD12.
4. these pins are powered by VDDSD3.
