+  *          This file provides extended firmware functions to manage the following

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