                  Function (AF) using GPIO_PinAFConfig() function.
             (++) Configure the desired pin in alternate function by:
                  GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF.
             (++) Select the type, pull-up/pull-down and output speed via
                  GPIO_PuPd, GPIO_OType and GPIO_Speed members.

            phase and last bit using the USART_ClockInit() function.
         (#) Enable the USART using the USART_Cmd() function.
         (#) Enable the NVIC and the corresponding interrupt using the function
            USART_ITConfig() if you need to use interrupt mode.
