Data transfers functions.

 ===============================================================================
                      ##### IO operation functions #####
 ===============================================================================
    [..]
    This subsection provides a set of functions allowing to manage the I2C data
    transfers.

    (#) There are two modes of transfer:
       (++) Blocking mode : The communication is performed in the polling mode.
            The status of all data processing is returned by the same function
            after finishing transfer.
       (++) No-Blocking mode : The communication is performed using Interrupts
            or DMA. These functions return the status of the transfer startup.
            The end of the data processing will be indicated through the
            dedicated I2C IRQ when using Interrupt mode or the DMA IRQ when
            using DMA mode.

    (#) Blocking mode functions are :

        (++) HAL_I2C_DisableListen_IT()
        (++) HAL_I2C_Master_Abort_IT()

        (++) HAL_I2C_Master_Transmit_DMA()
        (++) HAL_I2C_Master_Receive_DMA()
