/*! \brief Example application.
*
* Example application. This example configures USARTE0 for with the parameters:
* - 8 bit character size
* - No parity
* - 1 stop bit
* - 9600 Baud
*
* This function then sends three bytes and tests if the received data is
* equal to the sent data. The code can be tested by connecting PC3 to PC2. If
* the variable 'success' is true at the end of the function, the three bytes
* have been successfully sent and received.
