  ==============================================================================
               ##### I2C peripheral extension features  #####
  ==============================================================================

  [..] Comparing to other previous devices, the I2C interface for STM32F427xx/437xx/
       429xx/439xx devices contains the following additional features :

       (+) Possibility to disable or enable Analog Noise Filter
       (+) Use of a configured Digital Noise Filter

                     ##### How to use this driver #####
  ==============================================================================
  [..] This driver provides functions to configure Noise Filter
    (#) Configure I2C Analog noise filter using the function HAL_I2C_AnalogFilter_Config()
    (#) Configure I2C Digital noise filter using the function HAL_I2C_DigitalFilter_Config()
