DEMO90.c: A demonstration program showing how to use the Timer function.
          **press '0' to reset timer.
          **press 'q' to quit program.

Compiler: BC++ 3.1,
          Turbo C++ 1.01 (3.01),
          MSVC 1.52
          
Compile mode: large

Project: DEMO90.c
         ..\..\Lib\upac5000.lib

Hardware: uPAC-5000

Description
    You can use timer functions to time program execution by calling the member functions start and stop within your program,
    and then using TimerReadValue() to return the elapsed time.
    
    Max. TimerValue: 4,294,967,295 ms (0xFFFFFFFF) = 4,294,967.295 sec = 49.7 days
    
    TimerOpen(): Starts the timer.
    TimerClose(): Stops the timer.
                  If TimerOpen() is called within your program, it must call TimerClose() before exiting.
    TimerReadValue(): Returns the elapsed time. The time unit for ticks is 1 ms.
    TimerResetValue(): Resets the elapsed time to zero.
                       The accumulated elapsed time is preserved until a TimerResetValue() call.
