==============================================================================
##### 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
