topmem.c: Demonstration of the AllocateTopMemory() function.
         
Compiler: BC++ 3.1, 
          Turbo C ++ 1.01(3.01) (free from http://community.borland.com/museum)

Compile mode: Large

Hordware: 7188E

Note: download topmem.exe to Flash and run it, will get:
        i7188E>run
        addr=3FF9:0000
        First time run the program(topmem.exe)
        set data flag and set data to "0x12 0x34 0xAB 0xCD"
        Wait WDT to reset system...
        i7188E>run    <--- after system reset by WDT, run it again
        addr=3FF9:0000
        Find last data flag
        data:0x12 0x34 0xAB 0xCD  <--- the data saved before system reset by WDT will not lost.
