摘要:在单片机中,嘴是数据输入缓冲器,数据输出驱动器和闩锁在一个I / O电路和许多其他功能的集合。 MCS-51的四端口结构的电路基本上是相同的,但它们也有不同的特点,所以目标口之间的差异的功能和使用。在学习掌握每个端口必须使用。

美国ATMEI MCS-51是由低电压,高性能8位微控制器,可电反复擦除FLASH程序存储器,2k字节和128字节的随机存取数据存储器RAM。设备使用ATMEI的公司的高密度,非易失性存储器技术生产,与标准MCS-51指令集和引脚兼容的产品,但除了端口P0,P2,啤酒,,,针,它是不平行扩展非总线微控制器的总线。

American ATMEI MCS-51 is produced by low-voltage, high-performance 8-bit microcontroller with 2k bytes that can be electrically erased repeatedly FLASH program memory , and 128 bytes of random access data memory RAM. Device uses ATMEI company high-density, non-volatile memory technology production, with the standard MCS-51 instruction set and pin-compatible products , but in addition to port P0 , P2, and ALE,,, pin , it is not parallel expansion bus for non- bus microcontrollers.


单片机是由运算器,控制器,存储器,输入设备和输出设备总共有五个基本要素组成。芯片是包括一个计算装置,一个控制器,一个小的内存量,基本输入输出接口电路,串行接口电路,中断和定时器电路都集成在一个芯片上有限大小的。

SCM is determined by the operator, controller , memory , input devices , and output devices of a total of five basic components . Chip is to include a computing device , a controller , a small amount of memory , the basic input-output interface circuit , a serial interface circuit , interrupt and timer circuits are all integrated in a chip of limited size .


MCS-51单片机通过内部的逻辑结构,以掌握的逻辑结构和单片机内部的各个组成部分的功能和特性。即:中央处理器(CPU),内部数据存储器,内部程序存储器,定时器/计数器,并行I / O端口,串行端口,中断控制系统,时钟电路,位处理器,总线。

MCS-51 microcontroller via the internal logical structure to grasp the logical structure and the internal microcontroller functions and features of the various components . Namely: the central processor (CPU), the internal data memory, internal program memory, timer / counter , parallel I / O ports, serial ports, interrupt control systems, the clock circuit , bit processor, bus.

First, the internal data memory low 128 unit , which includes the registers, bit-addressable area, the user RAM area , to master these units address assignment, role .

Second, the high internal data memory unit 128 , which is provided for the special register , the address range is 80H ~ FFH. The so-called special purpose register is different from the general-purpose registers , namely, the function or purpose of these registers are special provisions have been made for storage of the corresponding components of the control microcontroller commands, status , or data. In these special register , the focus to master the use of the following registers : the program counter , the accumulator A, B registers, program status word (PSW), the data pointer (DPTR).


MCS-51 stack operations : Stack is a computer important concept to grasp the following aspects:

80C51 chip with 4K ROM memory cell whose address is 0000H ~ 0FFFH, this is what we call the internal program memory ( or simply " the internal ROM"). Either on-chip or off-chip memory ( for non- chip ROM MCU ) , the program memory has a special set of reserved units 0000H ~ 002AH, use with caution.

Interrupt response , the system can press the interrupt type , automatically go to the first address of each interrupt zone to execute the program. Therefore, the address area in the interrupt service routine should be stored . But usually , eight units difficult able to save a complete interrupt service routine , it is generally also from the first address of the interrupt address area storing an unconditional branch to the interrupt response, via an interrupt address area , then go to the interrupt service routine the act论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
