        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...
        7188XA>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.
