Detailed Description
Data transfers management functions.
===============================================================================
##### Data transfers management functions #####
===============================================================================
[..] This subsection provides a set of functions allowing to manage
the I2C data transfers.
[..] The read access of the I2C_RXDR register can be done using
the I2C_ReceiveData() function and returns the received value.
Whereas a write access to the I2C_TXDR can be done using I2C_SendData()
function and stores the written data into TXDR.
