单片微型机是84年九月在巴黎召开的第九届世界计算机大会上所确认的微型机三个主要发展方向之一,它在微型机应用领域中占有十分重要的地位。在各发达国家中,单片微型机已广泛用于各种仪器仪表,机械控制设备、电子游戏及各种军用器械和宇航设备。在我国,它的应用也正遂步得到重视。为配合广大用户使用单片机、邵阳市自动化学会和邵阳市电子研究所最近编译出版了《MOTORLA M6805系列单片微型计算机》,该书在国内首次系统地介绍了M6805系列单片机的硬件结构,指示系统及硬件、软件的应用。全书十八万字,共分七章,並在附录中给出了各系列产品的电气特 The one-chip microcomputer is one of the three main development directions of the mini-machine which was confirmed at the Ninth World Computer Congress held in Paris in September, 84. It occupies a very important position in the field of micro-machine applications. In developed countries, single-chip microcomputer has been widely used in various instruments, mechanical control equipment, video games and a variety of military equipment and aerospace equipment. In our country, its application is also getting attention. To cope with the vast number of users SCM, Shaoyang City Institute of Automation and Shaoyang City Institute of Electronics recently compiled a “MOTORLA M6805 series of single-chip microcomputer,” the book for the first time in China introduced the M6805 series microcontroller hardware architecture, instruction system and Hardware, software applications. The book 180,000 words, is divided into seven chapters, and in the appendix gives the electrical characteristics of the various products
