+
+  [..] 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()
