* Description: This is the test code that will reside in the QG8 demo
|
|
|
11 |
* to provide an out of the box experience. This simple code
|
|
|
12 |
* blinks LED2 and toggles LED1 when SW1 is pressed.
|

*
|
|
|

* Notes: Also serves as an example for the 9S08QG8 demo board.
|
|
|
15 |
* Created using CodeWarrior 3.1 for HC(S)08.
