+ ===============================================================================
+    [..]
+    The Extended SMARTCARD HAL driver can be used as follow:
+
+    (#) After having configured the SMARTCARD basic features with HAL_SMARTCARD_Init(), 
+        then if required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, 
+        auto-retry counter,...) in the hsc AdvancedInit structure.
