+  * @brief   FMPI2C Extended HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of FMPI2C Extended peripheral:
+  *           + Extended features functions

+  @verbatim
+  ==============================================================================
+               ##### FMPI2C peripheral Extended features  #####
+  ==============================================================================
+
+  [..] Comparing to other previous devices, the FMPI2C interface for STM32F4xx
+       devices contains the following additional features
+
+       (+) Possibility to disable or enable Analog Noise Filter
+       (+) Use of a configured Digital Noise Filter
+       (+) Disable or enable Fast Mode Plus
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..] This driver provides functions to configure Noise Filter and Wake Up Feature
+    (#) Configure FMPI2C Analog noise filter using the function HAL_FMPI2CEx_ConfigAnalogFilter()
+    (#) Configure FMPI2C Digital noise filter using the function HAL_FMPI2CEx_ConfigDigitalFilter()
+    (#) Configure the enable or disable of fast mode plus driving capability using the functions :
+          (++) HAL_FMPI2CEx_EnableFastModePlus()
+          (++) HAL_FMPI2CEx_DisableFastModePlus()
