(3 mA), the use of GPIOs PC13 to PC15 in output mode is limited: the speed should not exceed 2 MHz with a maximum
load of 30 pF and these IOs must not be used as a current source (e.g. to drive an LED).
after reset (because these registers are not reset by the main reset). For details on how to manage these IOs, refer to the
Battery backup domain and BKP register description sections in the STM32F10xxx reference manual, available from the
STMicroelectronics website: www.st.com.

TFBGA64 package are configured as OSC_IN/OSC_OUT after reset, however the functionality of PD0 and PD1 can be
remapped by software on these pins. For the LQFP100 package, PD0 and PD1 are available by default, so there is no
need for remapping. 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.
