+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The UART HAL driver can be used as follows:
+
+    (#) Declare a UART_HandleTypeDef handle structure.
+
+    (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) UART pins configuration:
+            (+++) Enable the clock for the UART GPIOs.
+            (+++) Configure these UART pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
+             and HAL_UART_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
+             and HAL_UART_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 UART 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, Word Length, Stop Bit, Parity, Hardware
+        flow control and Mode(Receiver/Transmitter) in the Init structure.
+
+    (#) For the UART asynchronous mode, initialize the UART registers by calling
+        the HAL_UART_Init() API.
+
+    (#) For the UART Half duplex mode, initialize the UART registers by calling
+        the HAL_HalfDuplex_Init() API.
+
+    (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
+
+    (#) For the Multi-Processor mode, initialize the UART registers by calling
+        the HAL_MultiProcessor_Init() API.
+
+     [..]
+       (@) The specific UART interrupts (Transmission complete interrupt,
+            RXNE interrupt and Error Interrupts) will be managed using the macros
+            __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
+            and receive process.
+
+     [..]
+       (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
+            low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customized
+            HAL_UART_MspInit() API.
+
+     [..]
+        Three operation modes are available within this driver :
+
+     *** Polling mode IO operation ***
+     =================================
+     [..]
+       (+) Send an amount of data in blocking mode using HAL_UART_Transmit()
+       (+) Receive an amount of data in blocking mode using HAL_UART_Receive()
+
+     *** Interrupt mode IO operation ***
+     ===================================
+     [..]
+       (+) Send an amount of data in non blocking mode using HAL_UART_Transmit_IT()
+       (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_TxCpltCallback
+       (+) Receive an amount of data in non blocking mode using HAL_UART_Receive_IT()
+       (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_RxCpltCallback
+       (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
+            add his own code by customization of function pointer HAL_UART_ErrorCallback
+
+     *** DMA mode IO operation ***
+     ==============================
+     [..]
+       (+) Send an amount of data in non blocking mode (DMA) using HAL_UART_Transmit_DMA()
+       (+) At transmission end of half transfer HAL_UART_TxHalfCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_TxHalfCpltCallback
+       (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_TxCpltCallback
+       (+) Receive an amount of data in non blocking mode (DMA) using HAL_UART_Receive_DMA()
+       (+) At reception end of half transfer HAL_UART_RxHalfCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_RxHalfCpltCallback
+       (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_UART_RxCpltCallback
+       (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
+            add his own code by customization of function pointer HAL_UART_ErrorCallback
+       (+) Pause the DMA Transfer using HAL_UART_DMAPause()
+       (+) Resume the DMA Transfer using HAL_UART_DMAResume()
+       (+) Stop the DMA Transfer using HAL_UART_DMAStop()
+
+     *** UART HAL driver macros list ***
+     =============================================
+     [..]
+       Below the list of most used macros in UART HAL driver.
+
+      (+) __HAL_UART_ENABLE: Enable the UART peripheral
+      (+) __HAL_UART_DISABLE: Disable the UART peripheral
+      (+) __HAL_UART_GET_FLAG : Check whether the specified UART flag is set or not
+      (+) __HAL_UART_CLEAR_FLAG : Clear the specified UART pending flag

+    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+    in asynchronous mode.
+      (+) For the asynchronous mode only these parameters can be configured:
+        (++) Baud Rate
+        (++) Word Length
+        (++) Stop Bit
+        (++) Parity: If the parity is enabled, then the MSB bit of the data written
+             in the data register is transmitted but is changed by the parity bit.
+             Depending on the frame length defined by the M bit (8-bits or 9-bits),
+             please refer to Reference manual for possible UART frame formats.
+        (++) Hardware flow control
+        (++) Receiver/transmitter modes
+        (++) Over Sampling Method
+    [..]
+    The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init() and HAL_MultiProcessor_Init() APIs
