* This function is the handler which performs processing to receive data from

* the UartLite. The size of the data present in the FIFO is not known when
* this function is called.
*
* This handler provides an example of how to handle data for the UartLite,

*
* @param CallBackRef contains a callback reference from the driver, in
* this case it is the instance pointer for the UartLite driver.
* @param EventData contains the number of bytes sent or received for sent
* and receive events.

* @note None.
