+               ##### 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
