Data transfers functions.
===============================================================================
##### Data transfers functions #####
===============================================================================
[..] This section provides a set of functions allowing to manage the SPI or I2S
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
SPI_ReceiveData8() (when data size is equal or inferior than 8bits) and.
SPI_I2S_ReceiveData16() (when data size is superior than 8bits)function
and returns the Rx buffered value. Whereas a write access to the SPI_DR
can be done using SPI_SendData8() (when data size is equal or inferior than 8bits)
and SPI_I2S_SendData16() (when data size is superior than 8bits) function
and stores the written data into Tx buffer.
