+ * @author MCD Application Team
+ * @version V1.2.0
+ * @date 06-February-2015
+ * @brief I2C Extended HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of I2C Extended peripheral:
+ * + Extended features functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### I2C peripheral Extended features #####
+ ==============================================================================
+
+ [..] Comparing to other previous devices, the I2C interface for STM32L0XX
+ 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
+ (#) Configure I2C Analog noise filter using the function HAL_I2CEx_ConfigAnalogFilter()
+ (#) Configure I2C Digital noise filter using the function HAL_I2CEx_ConfigDigitalFilter()
+ (#) Configure the enable or disable of I2C Wake Up Mode using the functions :
+ + HAL_I2CEx_EnableWakeUp()
+ + HAL_I2CEx_DisableWakeUp()
+ (#) Configure the enable or disable of fast mode plus driving capability using the functions :
+ + HAL_I2CEx_EnableFastModePlus()
+ + HAL_I2CEx_DisbleFastModePlus()
