  * @brief   SMBUS Extended HAL module driver.
  *          This file provides firmware functions to manage the following
  *          functionalities of SMBUS Extended peripheral:
  *           + Extended features functions
  *

  ==============================================================================
               ##### SMBUS peripheral Extended features  #####
  ==============================================================================

  [..] Comparing to other previous devices, the SMBUS interface for STM32WLxx
       devices contains the following additional features

       (+) Disable or enable Fast Mode Plus

                     ##### How to use this driver #####
  ==============================================================================
    (#) Configure the enable or disable of fast mode plus driving capability using the functions :
          (++) HAL_SMBUSEx_EnableFastModePlus()
          (++) HAL_SMBUSEx_DisableFastModePlus()
