@verbatim
==============================================================================
##### I2C peripheral Extended features #####
==============================================================================
[..] Comparing to other previous devices, the I2C interface for STM32G0xx
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(s)
(+) Disable or enable Fast Mode Plus
##### How to use this driver #####
==============================================================================
[..] This driver provides functions to configure Noise Filter and Wake Up Feature
(#) 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()
