* - STM32_LSECLK.
* - STM32_HSECLK.
* .
* One of the following macros must also be defined:
* - STM32F10X_LD_VL for Value Line Low Density devices.
* - STM32F10X_MD_VL for Value Line Medium Density devices.
* - STM32F10X_LD for Performance Low Density devices.
* - STM32F10X_MD for Performance Medium Density devices.
* - STM32F10X_HD for Performance High Density devices.
* - STM32F10X_XL for Performance eXtra Density devices.
* - STM32F10X_CL for Connectivity Line devices.
