Detailed Description

Data transfers functions.

 ===============================================================================
                      ##### Data transfers functions #####
 ===============================================================================  

 [..] This section provides a set of functions allowing to manage the SPI data 
      transfers. In reception, data are received and then stored into an internal 
      Rx buffer while. In transmission, data are first stored into an internal Tx 
      buffer before being transmitted.

 [..] The read access of the SPI_DR register can be done using the SPI_I2S_ReceiveData()
      function and returns the Rx buffered value. Whereas a write access to the SPI_DR 
      can be done using SPI_I2S_SendData() function and stores the written data into 
      Tx buffer.
