计算机的指令系统是表征计算机性能的重要指标,每种计算机都有自己的指令系统。MCS—51单片机的指令系统是一个具有255种代码的集合,绝大多数指令包含两个基本部分:操作码和操作数。操作码表明指令要执行的操作的性质;操作数说明参与操作的数据或数据所存放的地址。MCS—51指令系统中所有程序指令是以机器语言形式表示,可分为单字节、双字节、三字节3种格式。用二进制编码表示的机器语言由于阅读困难,且难以记忆。因此在微机控制系统中采用汇编语言指令来编写程序。本章介绍MCS—51指令系统就是以汇编语言来描述的。 一条汇编语言指令中最多包含4个区段,如下所示: 标号: 操作码目的操作数,源源操作数;注释 标号与操作码之间“:”隔开; 操作码与操作数之间用“空格”隔开; 目的操作数和源源操作数之间有“,”分隔; 操作数与注释之间用“;”隔开。 标号是由用户定义的符号组成,必须用英文大写字母开始。标号可有可无,若一条指令中有标号,标号代表该指令所存放的第一个字节存储单元的地址,故标号又称为符号地址,在汇编时,把该地址赋值给标号。 操作码是指令的功能部分,不能缺省。MCS—51指令系统中共有42种助记符,代表了33种不同的功能。例如MOV是数据传送的助记符。 操作数是指令要操作的数据信息。根据指令的不同功能,操作数的个数有3、2、1或没有操作数。例如MOV A,#20H,包含了两个操作数A和#20H,它们之间用“,”隔开。注释可有可无,加入注释主要为了便于阅读,程序设计者对指令或程序段作简要的功能说明,在阅读程序或调试程序时将会带来很多方便。

本软件是关于MAX338, MAX339的英文数据手册:MAX338, MAX339 8通道/双4通道、低泄漏、CMOS模拟多路复用器 The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions. These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.
