/**
 * @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:
 *          - STM32F100xB for Value Line Medium Density devices.
 *          - STM32F100xE for Value Line High Density devices.
 *          - STM32F101x6, STM32F102x6, STM32F103x6 for Performance
 *            Low Density devices.
 *          - STM32F101xB, STM32F102xB, STM32F103xB for Performance
 *            Medium Density devices.
 *          - STM32F101xE, STM32F103xE for Performance High Density devices.
 *          - STM32F101xG, STM32F103xG for Performance eXtra Density devices.
 *          - STM32F105xC, STM32F107xC for Connectivity Line devices.
 *          .
