1) The “Type” column indicates the type of the pin: IO = input/output, I = input only, O = output only, S = power supply.
2) The listed functionalities include only the most important functionalities – please refer to the STM32F103xC data sheet for a full list.
3) Functions listed in italic letters are selected by default if the device is not reprogrammed. GPIOs are analog inputs by default.
4) Any pin marked as GPIO can be configured as indicator for incoming or outgoing packets on network or serial interfaces.
