The following program demonstates the required configuration of the programmable counter
array watchdog timer peripheral for the following chips : 

Dallas Semiconductor DS80C320
Dallas Semiconductor DS80C323
Dallas Semiconductor DS87C520/DS83C520
Dallas Semiconductor DS87C530
Dallas Semiconductor DS89C420

After configuring the watchdog timer, the program runs a continuous loop to allow the timer to 
reset the microcontroller

To run this program...

1. Build the project (Project Menu, Build Target)
2. Start the debugger (Debug Menu, Start/Stop Debug Session)
3. View the PCA Timer perioheral (Peripheral Menu, Timer, PCA Timer)
4. View the PCA Watchdog Module (Peripheral Menu, Timer, PCA Module, Counter 4)
5. Select Periodic Window Update (View, Periodic Window Update)
5. Run the program (Debug Menu, Go)

The debugger will run a script that will display the message:
"PCA Watchdog Time will invoke Reset" and display the number of resets to have occured.
