1. 本程序实现了两个功能,即6264的随机读与写 2. 实现对同一端口既作输出又作输入,如程序中 PORTA作为数据输入输出口； 3. 测试接线方式见Proteus仿真文件。-1. This procedure has two functions, that is, 6264 randomized read and write 2. To achieve the same port for both output also for input, such as PORTA process as a data input and output port 3. Test Connection documents, see Proteus simulation.
