+                        ##### How to use this driver #####
+ ===============================================================================
+  [..]
+     The SWPMI HAL driver can be used as follows:
+
+    (#) Declare a SWPMI_HandleTypeDef handle structure (eg. SWPMI_HandleTypeDef hswpmi).
+
+    (#) Initialize the SWPMI low level resources by implementing the HAL_SWPMI_MspInit() API:
+        (##) Enable the SWPMIx interface clock with __HAL_RCC_SWPMIx_CLK_ENABLE().
+        (##) SWPMI IO configuration:
+            (+++) Enable the clock for the SWPMI GPIO.
+            (+++) Configure these SWPMI pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_SWPMI_Transmit_IT()
+             and HAL_SWPMI_Receive_IT() APIs):
+            (+++) Configure the SWPMIx interrupt priority with HAL_NVIC_SetPriority().
+            (+++) Enable the NVIC SWPMI IRQ handle with HAL_NVIC_EnableIRQ().
+
+        (##) DMA Configuration if you need to use DMA process (HAL_SWPMI_Transmit_DMA()
+             and HAL_SWPMI_Receive_DMA() APIs):
+            (+++) Declare a DMA handle structure for the Tx/Rx channels.
+            (+++) Enable the DMAx interface clock.
+            (+++) Configure the declared DMA handle structure with the required
+                  Tx/Rx parameters.
+            (+++) Configure the DMA Tx/Rx channels and requests.
+            (+++) Associate the initialized DMA handle to the SWPMI DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete
+                  interrupt on the DMA Tx/Rx channels.
+
+    (#) Program the Bite Rate, Tx Buffering mode, Rx Buffering mode in the Init structure.
+
+    (#) Enable the SWPMI peripheral by calling the HAL_SWPMI_Init() function.

+    This subsection provides a set of functions allowing to manage the SWPMI
+     data transfers.
+
+    (#) There are two modes of transfer:
+       (++) Blocking mode: The communication is performed in polling mode.
+            The HAL status of all data processing is returned by the same function
+            after finishing transfer.
+       (++) Non-Blocking mode: The communication is performed using Interrupts
+           or DMA. The end of the data processing will be indicated through the
+           dedicated SWPMI Interrupt handler (HAL_SWPMI_IRQHandler()) when using Interrupt mode or
+           the selected DMA channel interrupt handler when using DMA mode.
+           The HAL_SWPMI_TxCpltCallback(), HAL_SWPMI_RxCpltCallback() user callbacks
+           will be executed respectively at the end of the transmit or receive process.
+           The HAL_SWPMI_ErrorCallback() user callback will be executed when a communication error is detected.
+
+    (#) Blocking mode API's are:
+        (++) HAL_SWPMI_Transmit()
+        (++) HAL_SWPMI_Receive()
+
+    (#) Non-Blocking mode API's with Interrupt are:
+        (++) HAL_SWPMI_Transmit_IT()
+        (++) HAL_SWPMI_Receive_IT()
+        (++) HAL_SWPMI_IRQHandler()
+
+    (#) Non-Blocking mode API's with DMA are:
+        (++) HAL_SWPMI_Transmit_DMA()
+        (++) HAL_SWPMI_Receive_DMA()
+        (++) HAL_SWPMI_DMAPause()
+        (++) HAL_SWPMI_DMAResume()
+        (++) HAL_SWPMI_DMAStop()
+
+    (#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode:
+        (++) HAL_SWPMI_TxHalfCpltCallback()
+        (++) HAL_SWPMI_TxCpltCallback()
+        (++) HAL_SWPMI_RxHalfCpltCallback()
+        (++) HAL_SWPMI_RxCpltCallback()
