+    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+    in asynchronous mode.
+      (+) For the asynchronous mode the parameters below can be configured:
+        (++) Baud Rate
+        (++) Word Length (Fixed to 8-bits only for LIN mode)
+        (++) Stop Bit
+        (++) Parity
+        (++) Hardware flow control
+        (++) Receiver/transmitter modes
+        (++) Over Sampling Method
+        (++) One-Bit Sampling Method
+      (+) For the asynchronous mode, the following advanced features can be configured as well:
+        (++) TX and/or RX pin level inversion
+        (++) data logical level inversion
+        (++) RX and TX pins swap
+        (++) RX overrun detection disabling
+        (++) DMA disabling on RX error
+        (++) MSB first on communication line
+        (++) auto Baud rate detection
+    [..]
+    The HAL_LIN_Init() and HAL_RS485Ex_Init() APIs follows respectively the LIN and 
+    the UART RS485 mode configuration procedures (details for the procedures are 
+    available in reference manual).

+/*
+  Additional Table:  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.
+                     According to device capability (support or not of 7-bit word length),
+                     frame length is either defined by the M bit (8-bits or 9-bits)
