DEMO92.c: Use StopWatch channel 0 for LED ON/OFF.

Compiler: BC++ 3.1, 
          Turbo C ++ 1.01(3.01) (free from http://community.borland.com/museum)
          MSC 6.0,
          MSVC 1.52.

Compile mode: Large

Project: DEMO92.c
         ..\..\Lib\(7188XAL.Lib,7188XBL.Lib,7188XCL.Lib or 7188EL.Lib)

Hardware: 7188

Note: Function used:
      TimerOpen --> begin to use I-7188 timer
      TimerClose --> stop to use timer
      StopWatchStart  --> start to count time interval
      StopWatchReadValue -->to decide if time is up.
      Use StopWatch to count 500ms(0.5s) to turn LED ON or OFF.
