  @par Example description

  This example provides a basic communication between UART1 and UART3 using interrupts.
  UART3 sends TxBuffer2 to UART1 which sends TxBuffer1 to UART3. The data received 
  by UART1 and UART3 are stored respectively in RxBuffer1 and RxBuffer2. The data
  transfer is managed in UART1_TX_IRQHandler,UART1_RX_IRQHandler,UART3_TX_IRQHandler 
  and UART3_RX_IRQHandler in stm8s_it.c file.


  The UART1 and UART3 are configured as follows:
   - BaudRate = 9600 baud  
   - Word Length = 8 Bits
   - One Stop Bit
   - No parity
   - Receive and transmit enabled
   - UART1 Clock disabled

  @par Hardware and Software environment

  - This example runs on STM8S and STM8A High density devices only.
      
  - This example has been tested with STMicroelectronics STM8/128-EVAL evaluation 
    board and can be easily tailored to any other development board.

  - STM8/128-EVAL Set-up
    - Connect UART1_Tx(PA.05) to UART3_Rx(PD.06) and UART1_Rx(PA.04) to UART3_Tx(PD.05)
      or connect a null-modem female/female RS232 cable between CN15 and CN13.
  

  @par How to use it ?

  In order to make the program work, you must do the following :

  - Copy all source files from this example folder to the template folder under
    Project\Template
  - Open your preferred toolchain 
  - Rebuild all files and load your image into target memory
  - Run the example
  - Communication result in Receiver/ Transmitter modes can be checked respectively 
    via TransferStatus2 and TransferStatus1 variables.
  
  @note
  - High-Density STM8A devices are the STM8AF52xx STM8AF6269/8x/Ax,
    STM8AF51xx, and STM8AF6169/7x/8x/9x/Ax microcontrollers where the Flash memory
    density ranges between 32 to 128 Kbytes
  - Medium-Density STM8A devices are the STM8AF622x/4x, STM8AF6266/68,
    STM8AF612x/4x, and STM8AF6166/68 microcontrollers where the Flash memory 
    density ranges between 8 to 32 Kbytes
  - High-Density STM8S devices are the STM8S207xx, STM8S007 and STM8S208xx microcontrollers
    where the Flash memory density ranges between 32 to 128 Kbytes.
  - Medium-Density STM8S devices are the STM8S105x and STM8S005 microcontrollers
    where the Flash memory density ranges between 16 to 32-Kbytes.
  - Low-Density STM8S devices are the STM8S103xx, STM8S003 and STM8S903xx microcontrollers
    where the Flash density is 8 Kbytes.
