* @file STM32F4xx/hal_lld.h
* @brief STM32F4xx/STM32F2xx 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_LSE_BYPASS (optionally).
* - STM32_HSECLK.
* - STM32_HSE_BYPASS (optionally).
* - STM32_VDD (as hundredths of Volt).
* .
* One of the following macros must also be defined:
* - STM32F2XX for High-performance STM32 F-2 devices.
* - STM32F401xx for High-performance STM32 F-4 devices.
* - STM32F40_41xxx for High-performance STM32 F-4 devices.
* - STM32F427_437xx for High-performance STM32 F-4 devices.
* - STM32F429_439xx for High-performance STM32 F-4 devices.
