* @brief I2C Extension HAL module driver.
|

* This file provides firmware functions to manage the following
|
||||
* functionalities of I2C extension peripheral:
|

==============================================================================
|

##### I2C peripheral extension features #####
|
||||
==============================================================================
|
||||
|
||||
[..] 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()
