    Comments:
 
    UART01 => It indicates the UART 01
    02 => Example interested length of the 16 bit data to be set
    AA    BB    CC    DD => Example data (0xAABB and 0xCCDD) to be set in <b>FH_UART01_SharedDataBuf_16Bits</b>
    DeviceAddress_01 => It shall be equal to the address of the device: FH_RFCommunication_DeviceAddress
    Function_UART => It is the function in the message frame
    UART_Commands_SSD16 => It is the command of the function in the message frame
