| * 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. |
