RE: Flush UART

Hi Pingu,

If you are not using FIFO API for UART.

1.	STOPRX and STOPTX
2.  UART->TXD = 0    // this is just to ensure predictable behaviour with flow control
3.	While(event_ready != 0){ clear event, read uart rxd}
4.	STARTTX and STARTRX

When not using flow control -> TXD byte will be transmitted immediately when written and cannot be stopped.
