Description: 随着微电子技术和超大规模集成电路技术的发展，单片微型计算机以其体积小、性价比高、功能强、可靠性高等独有的特点，在各个领域（如工业控制、家电产品、汽车电子、通信、智能仪器仪表）得到了广泛的应用。学习、使用单片机的人越来越多，而生产单片机的厂家很多，单片机种类繁杂，不知如何选择。据统计，八位单片机占全球单片机销量的65％。在八位单片机中，Intel公司的8051单片机内核已成为8位单片机事实上的标准。因此，对初学者而言，选择8051单片机来学习不失为明智的选择。
学习单片机，除了搞清单片机内部功能、存储空间分配及I/O接口外，还应掌握其指令系统。MCS－51共有111条指令，现介绍我们总结出的快速记忆MCS－51指令的方法，供大家参考。

Description: 这个源代码是关于MCS-51的无线接收，用89S52控制MT8870B进行DTMF解码。程序相当的经典，本人调试了几周后，达到了非常好的效果。误码率相当的小。我觉得好东西要大家分享的，所以今天我上传此代码，与大家共同分析进步。-the source code is on the MCS-51 wireless receiver, S52 control with 89 MT8870B for DTMF decoder. Quite the classic procedure, I debug a few weeks later, to achieve very good results. The error rate is very small. I think that good things should be shared, so I upload this code, and the analysis of common progress.

Description: MCS-51单片机有5个中断源，其中两个是由-INT0、-INT1引脚输入的外部中断源；另外三个是内部中断源即由T0、T1的溢出引起中断和串行口发送完一个字节或接收到一个字节数据引起中断。触发外部中断有两种方式，即下降沿引起中断或低电平引起中断。当编程TCON中的ITi（i=0、1）为1时，则引起触发的方式为边沿触发方式，反之(ITi=0)为低电平触发方式。每个中断源的中断请求能否得到响应要受两级“开关”的控制，即一个总“开关”
