* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "Check" task - This only executes every three seconds but has a high priority
* to ensure it gets processor time. Its main function is to check that all the
* standard demo tasks are still operational. If everything is running as
* expected then the check task will toggle an LED every 3 seconds. An error
* being discovered in any task will cause the toggle rate to increase to 500ms.
*
* "Reg test" tasks - These fill the registers with known values, then check
* that each register still contains its expected value. Each task uses
* different values. The tasks run with very low priority so get preempted very
* frequently. A register containing an unexpected value is indicative of an
* error in the context switching mechanism.
