6. Main function after the first backup domain power-up. Later on, it depends on the contents of the Backup registers even

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.

7. This alternate function can be remapped by software to some other port pins (if available on the used package). For more

details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual, available

from the STMicroelectronics website: www.st.com.

8. The pins number 2 and 3 in the VFQFPN36 package, and 5 and 6 in the LQFP48 and LQFP64 packages 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

more details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual.
