of 30 pF and these IOs must not be used as a current source (e.g. to drive an LED).

functionality of PD0 and PD1 can be remapped by software on these pins. For more details, refer to the Alternate function
I/O and debug configuration section in the STM32F10xxx reference manual.
The use of PD0 and PD1 in output mode is limited as they can only be used at 50 MHz in output mode.
