*
* \brief RF Abstraction Layer (RFAL)
*
* RFAL (RF Abstraction Layer) provides several functionalities required to
* perform RF/NFC communications. <br>The RFAL encapsulates the different
* RF ICs (ST25R3911, ST25R391x, etc) into a common and easy to use interface.
*
* It provides interfaces to configure the RF IC, set/get timings, modes, bit rates,
* specific handlings, execute listen mode, etc.
*
* Furthermore it provides a common interface to perform a Transceive operations.
* The Transceive can be executed in a blocking or non blocking way.<br>
* Additionally few specific Transceive methods are available to cope with the
* specifics of these particular operations.
*
* The most common interfaces are:
* <br> rfalInitialize()
* <br> rfalSetFDTPoll()
* <br> rfalSetFDTListen()
* <br> rfalSetGT()
* <br> rfalSetBitRate()
* <br> rfalSetMode()
* <br> rfalFieldOnAndStartGT()
* <br> rfalFieldOff()
* <br> rfalStartTransceive()
* <br> rfalGetTransceiveStatus()
* <br> rfalTransceiveBlockingTxRx()
*
* An usage example is provided here: \ref exampleRfalPoller.c
* \example exampleRfalPoller.c
