* 0.a
* Port for Motorola MCF5272 ColdFire microprocessor.
* Added some printf statements to the AppTasks to monitor multitasking. This
* is used with the BDM debugger and the console I/O libraries provided by CodeWarrior.
* M. Medonis 4/16/2002
*
* Commented out printf statements in the Tasks because they were causing errors.
* Added code to blink LEDs for the Avnet Coldfire board (5282 based).
* Modified for 5282 timer0.

*
* Description : This is an example of a startup task.  As mentioned in the book's text, you MUST
*               initialize the ticker only once multitasking has started.
* Arguments   : pdata   is the argument passed to 'AppStartTask()' by 'OSTaskCreate()'.
* Notes       : 1) The first line of code is used to prevent a compiler warning because 'pdata' is not
*                  used.  The compiler should not generate any code for this statement.
*               2) Interrupts are enabled once the task start because the I-bit of the CCR register was
*                  set to 0 by 'OSTaskCreate()'.
