 *  \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>&nbsp; rfalInitialize()
 *    <br>&nbsp; rfalSetFDTPoll()
 *    <br>&nbsp; rfalSetFDTListen()
 *    <br>&nbsp; rfalSetGT()
 *    <br>&nbsp; rfalSetBitRate()
 *    <br>&nbsp; rfalSetMode()
 *    <br>&nbsp; rfalFieldOnAndStartGT()
 *    <br>&nbsp; rfalFieldOff()
 *    <br>&nbsp; rfalStartTransceive()
 *    <br>&nbsp; rfalGetTransceiveStatus()
 *    <br>&nbsp; rfalTransceiveBlockingTxRx()
 *    
 *  An usage example is provided here: \ref exampleRfalPoller.c
