+ * @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 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()
