  ==============================================================================
               ##### I2C peripheral Extended features  #####
  ==============================================================================

  [..] Comparing to other previous devices, the I2C interface for STM32L4xx
       devices contains the following additional features

       (+) Possibility to disable or enable Analog Noise Filter
       (+) Use of a configured Digital Noise Filter
       (+) Disable or enable wakeup from Stop mode(s)
       (+) Disable or enable Fast Mode Plus

                     ##### How to use this driver #####
  ==============================================================================
  [..] This driver provides functions to configure Noise Filter and Wake Up Feature
    (#) Configure I2C Analog noise filter using the function HAL_I2CEx_ConfigAnalogFilter()
    (#) Configure I2C Digital noise filter using the function HAL_I2CEx_ConfigDigitalFilter()
    (#) Configure the enable or disable of I2C Wake Up Mode using the functions :
          (++) HAL_I2CEx_EnableWakeUp()
          (++) HAL_I2CEx_DisableWakeUp()
    (#) Configure the enable or disable of fast mode plus driving capability using the functions :
          (++) HAL_I2CEx_EnableFastModePlus()
          (++) HAL_I2CEx_DisableFastModePlus()
