1.基本实验:使用一片62256RAM,作为片外扩展的数据存贮器,先对其0000H~0EF1H单元写入
“0101 0101”(55H),然后将0000H~0EF1H单元内容依次读出,检查是否为“0101 0101”。若正
确,发光二极管L1闪烁发光,否则L1始终是亮的。
2.扩展实验:将上面的“检查是否为‘0101 0101’。若正确,发光二极管L1闪烁发光,否则L1始终
是亮的。”改成“若正确,发光二极管L0,L2,L4,L6为一组,L1,L3,L5,L7为一组,轮流闪烁发
光,否则L0~L7全亮”

Basic experiment: Using a 62256RAM, as extended data memory chip, the first unit of its 0000H ~ 0EF1H write " 0101 0101" (55H), and then 0000H ~ 0EF1H cell contents were read out to check the " 0101 0101. " If correct, L1 LED flashing light, or L1 is always bright. 2. Extension test: the above " Check whether the ' 0101 0101 ' . If the right LED flashing light L1, or L1 is always bright." To " If the right LED L0, L2, L4, L6 for a group , L1, L3, L5, L7 to a group flashing light, or L0 ~ L7 full bright "
