1. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current
2. After the first backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the
3. After reset, these pins are configured as SWDAT and SWCLK alternate functions, and the internal pull-up on SWDAT pin
