Detailed Description

Half-duplex mode function.

 ===============================================================================
                         Half-duplex mode function
 ===============================================================================  

  This subsection provides a function allowing to manage the USART 
  Half-duplex communication.
  
  The USART can be configured to follow a single-wire half-duplex protocol where 
  the TX and RX lines are internally connected.

  USART Half duplex communication is possible through the following procedure:
     1. Program the Baud rate, Word length, Stop bits, Parity, Mode transmitter 
        or Mode receiver and hardware flow control values using the USART_Init()
        function.
     2. Configures the USART address using the USART_SetAddress() function.
     3. Enable the USART using the USART_Cmd() function.
     4. Enable the half duplex mode using USART_HalfDuplexCmd() function.

Note:
----
  1. The RX pin is no longer used
  2. In Half-duplex mode the following bits must be kept cleared:
       - CLKEN bits in the USART_CR3 register.
       - SCEN and IREN bits in the USART_CR5 register.
