-  * @author  MCD Application Team
-  * @version V1.1.0RC2
-  * @date    14-May-2014
-  * @brief   I2C Extension HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of I2C extension peripheral:
-  *           + Extension features functions
-  *

-  ==============================================================================
-               ##### 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()
