[DSP program] ex1_RAMTest DL : 0: （1）测试外部数据RAM：根据我们定义的逻辑，外部RAM在数据空间中定义在0x8000－0xFFFF，共32k字，占据RAM中的低32K存储空间。提供2种测试方法，采用一种方式即可。硬件仿真模式下，将目标板上电。第一种方法：采用用程序测试实验程序所在目录ex1_RAMTest。该程序执行的功能是对外部数据RAM区0x8000－0xFFFF,从0x8000开始写并且读数据0x5555 。如果正常则写读下一个地址，直到。如果正常则所有的地址操作完毕后，核心板的指示灯会变亮。否则，如果写入数据后，读出的不正确，则指示灯会不断闪烁。在CCS2000中的操作如下： 1. Progect->Open,打开该目录中的工程文件。 2. Progect->Rebuild All,编译链接 3. File->Program 4. Debug->Go Main 5. Debug->RUN(快捷键F5) 如果正常可以看到灯在熄灭约4秒后变亮。（说明：对整个数据RAM区的操作时间其实很短，为便于观察，本程序中加入了延时）。打开View->Memory ，然后填入地址0x8000,然后在PAGE栏选择DATA。点击确定，即可显示0x8000地址开始的数据，用户会发现从这个地址开始往后的数据均为刚被写入的0x5555。 -(1) test the external data RAM: According to the definition of our logic, the external RAM is defined in the data space at 0x8000-0xFFFF, a total of 32k character occupy the RAM in the low 32K memory space.

Under normal circumstances, the high 16-bit operands in memory of the lower portion of the lower 16-bit operand in memory upper address unit. For example, a long operand 16782345H, it is stored in the memory of the way: (0060H) = 1678H (high word), (0061H) = 2345H (low word).
