+  * @date    26-June-2015
+  * @brief   Extended FMPI2C HAL module driver.
+  *
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the Inter Integrated Circuit (FMPI2C) peripheral:
+  *           + Extended Control methods

+  @verbatim
+  ==============================================================================
+               ##### FMPI2C peripheral extended features  #####
+  ==============================================================================
+
+  [..] Comparing to other previous devices, the FMPI2C 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
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..] This driver provides functions to configure Noise Filter
