/**
 * @file    STM32F1xx/hal_lld.h
 * @brief   STM32F1xx HAL subsystem low level driver header.
 * @pre     This module requires the following macros to be defined in the
 *          @p board.h file:
 *          - STM32_LSECLK.
 *          - STM32_HSECLK.
 *          - STM32_HSE_BYPASS (optionally).
 *          .
 *          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_HD_VL for Value Line High 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.
 *          .
