利用D触发器为TPC—1实验系统的A/D转换实验增加查询式接口

Using D Trigger to Add Inquiring Interface for TPC-1 Experiment System's A/D Transform Experiment

为了满足《微机原理》教学的需要,增加一个D触发器使TPC-1实验系统可完成利用查询式方法采样数据的A/D转换实验,并介绍了利用虚写端口的操作改变D触发器状态的技术.

For contented the requirement of the teaching of Micocoiaputer Principle, a D trigger is added to make TPC-1 experiment system accomplish the transform experiment by using inquiring approach to get data of A/D. The skill of using false writing port to change D trigger's state is introduced.
