* Filename:     DEMO9S08QG8_Test.c
* Author:       r1aald
* Revision:     1.0
*
* Description:  This is the test code that will reside in the QG8 demo
*                to provide an out of the box experience. This simple code
*                blinks LED2 and toggles LED1 when SW1 is pressed.
*
* Notes:        Also serves as an example for the 9S08QG8 demo board.
*               Created using CodeWarrior 3.1 for HC(S)08.
