+  *          This file provides firmware functions to manage the following
+  *          functionalities of the SMARTCARD peripheral:

+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The SMARTCARD HAL driver can be used as follow:
+    
+    (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+    (#) Associate a USART to the SMARTCARD handle hsc.
+    (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) SMARTCARD pins configuration:
+            (+++) Enable the clock for the SMARTCARD GPIOs.
+            (+++) Configure these SMARTCARD pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
+             and HAL_SMARTCARD_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+            (+++) The specific USART interrupts (Transmission complete interrupt, 
+                  RXNE interrupt and Error Interrupts) will be managed using the macros
+                  __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
+        (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
+             and HAL_SMARTCARD_Receive_DMA() APIs):
+            (+++) Declare a DMA handle structure for the Tx/Rx stream.
+            (+++) Enable the DMAx interface clock.
+            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.                
+            (+++) Configure the DMA Tx/Rx Stream.
+            (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
+
+    (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
+        the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
+        error enabling or disabling in the hsc Init structure.
+        
+    (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
+        in the hsc AdvancedInit structure.
+
+    (#) Initialize the SMARTCARD associated USART registers by calling
+        the HAL_SMARTCARD_Init() API. 
+    
+  [..]
+    (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by 
+        calling the customized HAL_SMARTCARD_MspInit() API.
