二、指令的記憶方法
1�指令操作數的有關符號
MCS－51的定址方式共有六種：立即數定址、直接定址、寄存器定址、寄存器間址、變
址定址、相對定址。我們必須掌握其表示的方法。
1）立即數與直接地址。ata表示八位立即數，＃data16表示是十六位立即數，data或
direct表示直接地址。
2）Rn(n=0－7)、A、B、CY、DPTR寄存器定址變數。

4）DPTR＋A、PC＋A表示變址定址的變數。
5）PC＋rel（相對量）表示相對定址變數。
記住指令的助記符，掌握不同定址方式的指令操作數的表示方法，為我們記憶匯編指
令打下了基礎。MCS－51指令雖多，但按功能可分為五類，
其中數據傳送類28條，算術運算類24條，邏輯操作類25條，控制轉移類17條，布爾位操作
類17條。在每類指令里，根據其功能，抓住其源、

我們約定，可能的目的操作數按（＃data/direct/A/Rn/@Ri）順序表示。
對於MOV指令，其目的操作數按A、Rn、direct、@Ri的順序書寫，則可以記住MOV的15
條指令。例如以累加器A為目的操作數，可寫出如下4條指令。
MOV A，＃data/direct/A/Rn/@Ri
以此類推，寫出其它指令。

由助記符CJNE形成的四條指令，也可以用圖示法表示，如圖3。
CJNE A，＃data，rel CJNE A，direct，rel
CJNE @Rn，＃data，rel CJNE @Ri，＃data，rel
另外，對於由（ANL、ORL、ARL）形成的18條邏輯操作指令，有關A的四條環移指令，
也可以用圖示法表示，請讀者自行畫出記憶。
3�相似功能歸類法
在MCS－51指令中，我們發現部分指令其操作碼不同，但功能相似，而操作數則完全一
樣。相似功能歸類法就是把具有這樣特點的指令放在一起記憶，
只要記住其中的一條，其餘的也就記住了。如加、減法的十二條指令，與、或、非的十八
條指令，現列舉如下。
ADD/ADDC/SUBB A，＃data/direct/Rn/@Ri
ANL/ORL/XRL A，＃data/direct/Rn/@Ri
ANL/ORL/XRL direct，＃data/a
上述每一排指令，功能相似，其操作數都相同。其它的如加1(INC)、減1(DEC)指令也
可照此辦理。
4�口訣記憶法
對於有些指令，我們可以把相關的功能用精練的語言編成一句話來記憶。如PUSH
direct和POP direct這兩條指令。
初學者常常分不清堆棧SP的變化情況，為此編成這樣一句話：(SP的內容)加1(direct的內
容)再入棧，(SP的內容)彈出(到direct單元)SP才減1。
又如乘法指令中積的存放，除法指令中被除數和除數以及商的存放，都可以編成口訣記憶
如下。
MUL AB 高位積(存於)B，低位積(存於)A。
DIV AB A除以B，商(存於)A余(下)B。
上面介紹了幾種快速記憶單片機指令的方法，希望能起到拋磚引玉的作用，相信讀者
在學習單片機的過程中能找到適合自己的方法來記憶。
但是，有了好的方法還不夠，還需要實踐，即多讀書上的例題和別人編寫的程序，自己再
結合實際編寫一些程序。只有這樣，
才能更好更快地掌握單片機指令系統。

Introction of Programmable controllers
From a simple heritage, these remarkable systems have evolved to not only replace electromechanical devices, but to solve an ever-increasing array of control problems in both process and nonprocess instries. By all indications, these microprocessor powered giants will continue to break new ground in the automated factory into the 1990s.
HISTORY
In the 1960s, electromechanical devices were the order of the day ass far as control was concerned. These devices, commonly known as relays, were being used by the thousands to control many sequential-type manufacturing processes and stand-along machines. Many of these relays were in use in the transportation instry, more specifically, the automotive instry. These relays used hundreds of wires and their interconnections to effect a control solution. The performance of a relay was basically reliable - at least as a single device. But the common applications for relay panels called for 300 to 500 or more relays, and the reliability and maintenance issues associated with supporting these panels became a very great challenge. Cost became another issue, for in spite of the low cost of the relay itself, the installed cost of the panel could be quite high. The total cost including purchased parts, wiring, and installation labor, could range from $30~$50 per relay. To make matters worse, the constantly changing needs of a process called for recurring modifications of a control panel. With relays, this was a costly prospect, as it was accomplished by a major rewiring effort on the panel. In addition these changes were sometimes poorly documented, causing a second-shift maintenance nightmare months later. In light of this, it was not uncommon to discard an entire control panel in favor of a new one with the appropriate components wired in a manner suited for the new process. Add to this the unpredictable, and potentially high, cost of maintaining these systems as on high-volume motor vehicle proction lines, and it became clear that something was needed to improve the control process – to make it more reliable, easier to troubleshoot, and more adaptable to changing control needs.
That something, in the late 1960s, was the first programmable controller. This first 『revolutionary』 system wan developed as a specific response to the needs of the major automotive manufacturers in the United States. These early controllers, or programmable logic controllers (PLC), represented the first systems that 1 could be used on the factory floor, 2 could have there 『logic』 changed without extensive rewiring or component changes, and 3 were easy to diagnose and repair when problems occurred.
It is interesting to observe the progress that has been made in the past 15 years in the programmable controller area. The pioneer procts of the late 1960s must have been confusing and frightening to a great number of people. For example, what happened to the hardwired and electromechanical devices that maintenance personnel were used to repairing with hand tools? They were replaced with 『computers』 disguised as electronics designed to replace relays. Even the programming tools were designed to appear as relay equivalent presentations. We have the opportunity now to examine the promise, in retrospect, that the programmable controller brought to manufacturing.
All programmable controllers consist of the basic functional blocks shown in Fig. 10. 1. We』ll examine each block to understand the relationship to the control system. First we look at the center, as it is the heart ( or at least the brain ) of the system. It consists of a microprocessor, logic memory for the storage of the actual control logic, storage or variable memory for use with data that will ordinarily change as a function power for the processor and memory. Next comes the I/O block. This function takes the control level signals for the CPU and converts them to voltage and current levels suitable for connection with factory grade sensors and actuators. The I/O type can range from digital (discrete or on / off), analog (continuously variable), or a variety of special purpose 『smart』 I/O which are dedicated to a certain application task. The programmer is shown here, but it is normally used only to initially configure and program a system and is not required for the system to operate. It is also used in troubleshooting a system, and can prove to be a valuable tool in pinpointing the exact cause of a problem. The field devices shown here represent the various sensors and actuators connected to the I/O. These are the arms, legs, eyes, and ears of the system, including push buttons, limit switches, proximity switches, photosensors, thermocouples, RTDS, position sensing devices, and bar code reader as input; and pilot lights, display devices, motor starters, DC and AC drives, solenoids, and printers as outputs.
No single attempt could cover its rapidly changing scope, but three basic characteristics can be examined to give classify an instrial control device as a programmable controller.
(1) Its basic internal operation is to solve logic from the beginning of memory to some specified point, such as end of memory or end of program. Once the end is reached, the operation begins again at the beginning of memory. This scanning process continues from the time power is supplied to the time it it removed.
(2) The programming logic is a form of a relay ladder diagram. Normally open, normally closed contacts, and relay coils are used within a format utilizing a left and a right vertical rail. Power flow (symbolic positive electron flow) is used to determine which coil or outputs are energized or deenergized.
(3) The machine is designed for the instrial environment from its basic concept; this protection is not added at a later date. The instrial environment includes unreliable AC power, high temperatures (0 to 60 degree Celsius), extremes of humidity, vibrations, RF noise, and other similar parameters.
General application areas
The programmable controller is used in a wide variety of control applications today, many of which were not economically possible just a few years ago. This is true for two general reasons: 1 there cost effectiveness (that is, the cost per I/O point) has improved dramatically with the falling prices of microprocessors and related components, and 2 the ability of the controller to solve complex computation and communication tasks has made it possible to use it where a dedicated computer was previously used.
Applications for programmable controllers can be categorized in a number of different ways, including general and instrial application categories. But it is important to understand the framework in which controllers are presently understood and used so that the full scope of present and future evolution can be examined. It is through the power of applications that controllers can be seen in their full light. Instrial applications include many in both discrete manufacturing and process instries. Automotive instry applications, the genesis of the programmable controller, continue to provide the largest base of opportunity. Other instries, such as food processing and utilities, provide current development opportunities.
There are five general application areas in which programmable controllers are used. A typical installation will use one or more of these integrated to the control system problem. The five general areas are explained briefly below.

Description
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel』s high-density nonvolatile memory technology and is compatible with the instry-standard MCS-51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
Function characteristic
The AT89C51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full plex serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.
Pin Description
VCC：Supply voltage.
GND：Ground.
Port 0：
Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as highimpedance inputs.Port 0 may also be configured to be the multiplexed loworder address/data bus ring accesses to external program and data memory. In this mode P0 has internal pullups.Port 0 also receives the code bytes ring Flash programming,and outputs the code bytes ring programverification. External pullups are required ring programverification.

Port 1
Port 1 is an 8-bit bi-directional I/O port with internal pullups.The Port 1 output buffers can sink/source four TTL inputs.When 1s are written to Port 1 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pullups.Port 1 also receives the low-order address bytes ring Flash programming and verification.
Port 2
Port 2 is an 8-bit bi-directional I/O port with internal pullups.The Port 2 output buffers can sink/source four TTL inputs.When 1s are written to Port 2 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 2 pins that are externally being pulled low will source current, because of the internal pullups.Port 2 emits the high-order address byte ring fetches from external program memory and ring accesses to external data memory that use 16-bit addresses. In this application, it uses strong internal pullupswhen emitting 1s. During accesses to external data memory that use 8-bit addresses, Port 2 emits the contents of the P2 Special Function Register.Port 2 also receives the high-order address bits and some control signals ring Flash programming and verification.
Port 3
Port 3 is an 8-bit bi-directional I/O port with internal pullups.The Port 3 output buffers can sink/source four TTL inputs.When 1s are written to Port 3 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 3 pins that are externally being pulled low will source current (IIL) because of the pullups.Port 3 also serves the functions of various special features of the AT89C51 as listed below:

Port 3 also receives some control signals for Flash programming and verification.

RST
Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device.
ALE/PROG
Address Latch Enable output pulse for latching the low byte of the address ring accesses to external memory. This pin is also the program pulse input (PROG) ring Flash programming.In normal operation ALE is emitted at a constant rate of 1/6 the oscillator frequency, and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped ring each access to external Data Memory.
If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only ring a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode.

PSEN
Program Store Enable is the read strobe to external program memory.When the AT89C51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped ring each access to external data memory.
EA/VPP
External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset.EA should be strapped to VCC for internal program executions.This pin also receives the 12-volt programming enable voltage(VPP) ring Flash programming, for parts that require12-volt VPP.

XTAL1
Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
XTAL2
Output from the inverting oscillator amplifier.

Oscillator Characteristics
XTAL1 and XTAL2 are the input and output, respectively,of an inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 1.Either a quartz crystal or ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 2.There are no requirements on the ty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide-by-two flip-flop, but minimum and maximum voltage high and low time specifications must be observed.

Figure 1. Oscillator Connections Figure 2. External Clock Drive Configuration

Idle Mode
In idle mode, the CPU puts itself to sleep while all the onchip peripherals remain active. The mode is invoked by software. The content of the on-chip RAM and all the special functions registers remain unchanged ring this mode. The idle mode can be terminated by any enabled interrupt or by a hardware reset.It should be noted that when idle is terminated by a hard ware reset, the device normally resumes program execution,from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-chip hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited. To eliminate the possibility of an unexpected write to a port pin when Idle is terminated by reset, the instruction following the one that invokes Idle should not be one that writes to a port pin or to external memory.

Power-down Mode
In the power-down mode, the oscillator is stopped, and the instruction that invokes power-down is the last instruction executed. The on-chip RAM and Special Function Registers retain their values until the power-down mode is terminated. The only exit from power-down is a hardware reset. Reset redefines the SFRs but does not change the on-chip RAM. The reset should not be activated before VCC is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and stabilize.

Program Memory Lock Bits
On the chip are three lock bits which can be left unprogrammed (U) or can be programmed (P) to obtain the additional features listed in the table below.

When lock bit 1 is programmed, the logic level at the EA pin is sampled and latched ring reset. If the device is powered up without a reset, the latch initializes to a random value, and holds that value until reset is activated. It is necessary that the latched value of EA be in agreement with the current logic level at that pin in order for the device to function properly.

MCU introction
Single-chip microcomputer single-chip microcomputer for short, is a typical embedded MCU, abbreviations for commonly used letters of the alphabet MCU microcontroller, it was first used in the field of instrial control. Single chip by chip only has dedicated processors grew out of the CPU. Early design concept through to a large number of peripherals and CPU integrated in a chip, making computer systems more smaller, easier to integrate into the complex and strict with volume control device. INTEL's Z80 processor design is the first in this thought out, and from then on, and dedicated single-chip processor development will go their separate ways. Early is 8-bit or 4-bit single-chip. One of the most successful is INTEL 8,031, good performance because of simple and reliable access to a great deal of praise. After that was developed at 8,031 MCS51 series microcontroller system. Single-chip computer system based on this system now in widespread use. As the field of instrial control requirements grow, beginning a 16-bit microcontroller, but because the price/performance is not satisfactory had not been very widely used. After 90 's with the development of consumer electronics, has been enormous increases in single-chip microcomputer. As INTEL i960 series in particular later ARM series of broad application, rapidly displacing 32-bit single-chip 16-bit single-chip high end position, and move into the mainstream. Traditional 8-bit MCU performance has been the rapid growth of processing power compared to the 80 's increased hundreds of times. At present, high-end 32-bit single-chip clock speed has more than 300MHz, straight after the mid 90 's a dedicated processor, but ordinary model factory price fell to $ 1, top-end models are only $ 10. Contemporary single-chip computer system development and use is no longer only in bare metal environment, large numbers of dedicated embedded operating systems are widely used on the full range of single-chip microcomputer. As handheld and mobile core processing for high-end MCU can even work directly with a dedicated Windows and Linux operating systems.

This kind of environment goal notonly is the AT89C51 automobile monolithic integrated circuit providesone kind of vigorous and healthy test environment, moreover willdevelop one kind to be able to be easy to expand and the repetitionuses for to confirm other several kind of future the monolithicintegrated circuit. Development this kind of environment has connectedAT89C51. This article discussed this kind of test environment designand the principle, it and each kind of hardware, does the softwareenvironment part interaction, how as well as use AT89C51. 1 introction 8 AT89C51 the CHMOS craft monolithic integrated circuit isdesigned uses in to process the high speed computation and the fastinput/output. The MCS-51 monolithic integrated circuit modelapplication is the high speed event control system. Commercial useincluding modem, motor control system, printer, photogravure press,air conditioning control system, disk driver and medical equipment.The automobile instry uses in the engine control system the MCS-51monolithic integrated circuit, the suspension system and locks on theother side the braking system. AT89C51 especially very good issuitable from benefits from on its processing speed and theenhancement piece the periphery function collection, such as: Theautomobile power control, the vehicles dynamic are hanging, lock onthe other side apply the brake with the stable control application. Asa result of these decisive applications, the market requirement onekind reliable has lowly disturbs the expense - potency controllerwhich the ambush responds, the service massive time and the eventactuates the integrated periphery ability which needs in the real-timeapplication, has outdoes the average processing power in the soleroutine package the central processor. Has the equipment economy andthe legal risk which the operation cannot be forecast are very high.Once enters the market, especially the ty decisiveness applicationsuch as autopilot or locks on the other side the braking system, willbe wrong will be in the financial resource forbids. The redesignexpense may reach as high as 500K US dollar的費用-效能控制器，服務大量時間和事件驅動的在實時應用需要的集成外圍的能力，具有在單一程序包中高出平均處理功率的中央處理器。擁有操作不可預測的設備的經濟和法律風險是很高的。一旦進入市場，尤其任務決定性應用諸如自動駕駛儀或反鎖制動系統，錯誤將是財力上所禁止的。重新設計的費用可以高達500K美元
