+This section targets to provide an overview of Guidelines Enforcement Plan (GEP).<br>
+ <br>
+This document will only focus on STMicroelectronics NFC RF Abstraction Layer (RFAL).<br>
+ <br>
+The project has been designed to comply with the standard ISO/IEC 9899:1999 ([C99]).
+<br>
+<br>
+<h3><a name="Tools">1. Tools version</a></h3>
+The tool used for MISRA compliance is:<br>
+<br>
+<b>PRQA Framework - v2.2.2</b><br>
+<br><br>
+It is composed of the following subcomponents:
+<br><br>
+<ul>
+<li><h4>Component: qacpp</h4></li>
+<ul>Version: 4.2.0</ul>
+<ul>Target: C++</ul>
+<li><h4>Component: rcma</h4></li>
+<ul>Version: 1.6.0</ul>
+<ul>Target: C_CPP</ul>
+<li><h4>Component: m3cm</h4></li>
+<ul>Version: 2.3.1</ul>
+<ul>Target: C</ul>
+<li><h4>Component: qac</h4></li>
+<ul>Version: 9.3.1</ul>
+<ul>Target: C</ul>
+<ul>
+<li><h5>Options:</h5></li>
+<ul>-d : __schedule_barrier=_ignore_semi</ul>
+<ul>-namelength : 63</ul>
+</ul>
+</ul>
+<h3><a name="Configuration">2. Configuration</a></h3>
+This section targets to provide the main configuration options used for MISRA compliance.<br>
+ <br>
+The project complies to [C99],<br>
+the variables length has been consequently set to a dedicated value (cf 'namelength' option in table above).

+<b>Nota: Calculation of Compliance Index</b><br>
+The Compliance Index is the percentage of groups which have no messages in them.<br>
+For each file it is calculated as follows:<br>
+<br>
+( Ntotal - Nerror  ) / Ntotal  x 100<br>
+<br>
+Ntotal  is the total number of enforced rules (i.e. the number of rules that have at least one message mapped to it directly).<br>
+Nerror  is the number of rules for which messages appear in that file.<br>
+The File Compliance Index is the mean of all the individual file compliances.<br>

+ *  \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()
