1. I = input, O = output, S = supply, HiZ = high impedance.
2. FT= 5 V tolerant.
3. Function availability depends on the chosen device. Refer to
4. PC13, PC14 and PC15 are supplied through the power switch, and so their use in ouptut mode is limited: they can be used
5. Available only on devices with a Flash memory density equal or higher than 64 Kbytes.
6. This alternate function can be remapped by software to some other port pins (if available on the used package). For more
7. For the LQFP48 and LQFP64 packages, the pins number 5 and 6 are configured as OSC_IN/OSC_OUT after reset,

only in output 2 MHz mode with a maximum load of 30 pF and only one pin can be put in output mode at a time.
details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual,
UM0306, available from the STMicroelectronics website: www.st.com.
however the functionality of PD0 and PD1 can be remapped by software on these pins.
