* Description : This is an example of a startup task.  As mentioned in the book's text, you MUST

* Arguments   : p_arg   is the argument passed to 'AppStartTask()' by 'OSTaskCreate()'.
* Notes       : 1) The first line of code is used to prevent a compiler warning because 'p_arg' 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()'.
