+ * The TR1PUTMIN of the ST25R3911 is 1152/fc (72/fs). The EMVCo test case TB0000 measures the TR1PUTMIN.
+ * It takes the default value of TR1PUTMIN (79/fs) and reduces it by 128/fc in every iteration.
+ * This results in a TR1PUTMIN of 1136/fc (71/fs) for the second iteration. The ST25R3911 sends a NAK because
+ * the TR1PUTMIN of the ST25R3911 (72/fs) is higher than 71/fs.
+ * Therefore the test suite assumes TR1PUTMIN of 1264/fc (79/fs).
+ * The test cases TB340.0 and TB435.0 uses the TR1PUTMIN to send frames too early. In order to correctly
+ * recognise these frames as being sent too early (starting inside reader deaf time), the MRT has to be

+ * \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()
