结合PPT——MSP-Simplex演讲稿Q版大家好，欢迎来到上海江诚公司。
今天由我来给大家讲解我们公司最新代理的一款新概念的IT应用设备——MSP-Simplex。
好，下面我们开始（打开PPT）。
（第一页）MSP-Simplex是Orris最新研发的针对中小企业IT信息化的多功能集成设备，我们把它归纳为ITinOne 企业信息一体化系统。
MSP的最大特点是它把企业信息化中常用的IT应用服务集成到一台设备中。
（指向下面的图标）它包含了无线接入、互联网接入、电话交换、电子邮件、内网交换、网络存储还有网络安全、传真服务等功能。
在下面我将对每个功能模块做详细的介绍。
（第二页）在今天这次演讲中，我将向大家介绍我们产品的理念和定位，接着是产品本身的规格、功能和应用，然后我向大家演示一下产品的管理系统，最后总结产品的优点。
（第三页）我们这款产品是为中小型企业量身打造的，以满足企业基础的IT需求。
此外它可以简化企业的IT设备，构建高校便捷的管理平台。
特别是后两者正成为了企业信息化发展的普遍趋势。
（第四页）如前所述，MSP是专门为中小型企业量身打造的，大企业、大公司比如世界500强不是我们的目标客户。
有很多中小企业，比如外贸/销售、软件外包、法律咨询、分支机构、外企代表处等。
他们需要的网络基础应用和IT应用都很适合我们的MSP-Simplex。
（第五页）MSP有着很好的市场的前景，如图所示，中国的中小企业数量每年都以7%-11%的速度递增，可以说处在一个高速的发展轨道之中。
MSP既代表了企业信息化的发展趋势，又面临着庞大的市场需求，前途十分的光明。
（第六页）下面我们来介绍一下产品的规格，这是MSP的前面板，左边是功能和状态指示灯，右边是四块SATA磁盘仓。
（第七页）这是MSP的后面板，MSP集成了24个百兆LAN口、2个千兆LAN口和1个WAN 口。

Failure to observe these requirements may invalidate the CE and UKCA conformance.• Install lightning surge protectors for those wires connect-ed to remote location. Refer to “LI GHTNI NG SURGE PROTECTION” section below .■POWER INPUT RATING & OPERATIONAL RANGE• Locate the power input rating marked on the product and confirm its operational range as indicated below:100 – 120V AC rating: 90 – 132V, 47 – 66 Hz, approx. 25VA 200 – 240V AC rating: 180 – 264V, 47 – 66 Hz, approx. 25VA 24V AC rating: 24V AC±10%, 47 – 66 Hz, approx. 25VA (MSP6)24V DC: 24V rating ±10%, approx. 0.6A• Built-in power fuse: 250V/1A rating; time delay .• A rush current 1.5 times as high as the above ratings can flow at startup.■GENERAL PRECAUTIONS• Remove the power supply to the actuator before wiring.■INSTALLATION• Indoor, or outdoor where the MSP is NOT exposed to di-rect sunlight • Ambient temperature: -5 to +55°C (23 to 131°F)• Operating humidity 30 to 85% RH (non-condensing)• Vibration: 2 G (19.6 m/s 2) max.• Install the MSP where it can be reached for maintenance and inspection. Be sure to allow at least 15 cm (6 inches)clearance above the cover.■OUTDOOR USE• When installing the MSP outdoor or where it is exposed to rain or water drops, be sure to fasten the cable connec-tor tightly and give some slack to the cable.• Do not mount the MSP in such a direction that the output stem or cable connector faces upward.■nal lines are not isolated. Use an isolator, if needed.• When wiring the unit using a cable longer than the standard 1-meter cable equipped to the non-terminal box model, use shielded cables for signal line, or install signal cables in a separate duct/pipe from power supply cables. ■LIGHTNING SURGE PROTECTION• In order to protect the unit from lightning surges enter-ing through cables, use of appropriate lightning surge protectors are recommended. For 24V DC power supply line, choose a surge protector with its maximum surge voltage 40V or less between lines.Recommended M-System model: MDP-D24. ■PID CONTROLLER• Choose PID parameters carefully so that the MV remains as stable as possible. Unstable control shortens the life of actuator and valve. ■O-RING, PACKING• When replacing the actuator cover after adjustments,check that the O-ring is securely placed in the groove.• When replacing the terminal box cover, check that the packing is properly applied.056 222 38 18SEN TRONIC AG■YOKE DESIGN• When a foreign object is caught in the valve, a thrust 4 times greater than the maximum rating could be gener-ated. Leave enough strength for mechanical components such as the yoke and the valve stem.• If the MSP is used in an application such as temperature control of a steam line, the temperature can rise higher than the ambient temperature due to heat conducted or radiated from the piping even when the ambient temper-ature is within an allowable range.U se a longer yoke to increase heat dissipation and apply insulating material.■AND ....• DO NOT loosen the screw fixing the potentiometer lever. Loosening it could cause a malfunction.• DO NOT step onto the actuator.• DO NOT allow a heavy object to rest on or against the actuator.PROTECTIVE FUNCTIONS■OVERLOAD (LOCK) PROTECTIONThe MSP is equipped with a protection circuit against over-load caused by, for example, valve catching an alien sub-stance.When an overload is detected, the MSP stops supplying power to the motor and the status LED blinks at 0.5 sec. intervals.The protection can be reset by applying an input signal to move the output stem in the opposite direction, or turning power off and restarting.If the overload (lock) protection is activated too often, check for the presence of foreign matter in the valve, inappropri-ate adjustments, excessive tightening of the valve gland, or other possible causes of the overload.Be sure to remove the cause of overload in order to avoid shortening the life of the product.■FUSEA fuse is equipped for protection against overload current. Ensure that the power LED turns on as the power supply is turned on. If the power LED remains off, check to see if the fuse is melted. Replace the melted fuse with a new one.I f the new fuse is melted again soon after replacement, there may be problems with the control PCB or the motor. Consult M-System or sales representative.■RESTARTING TIMERThe MSP is equipped with a timer circuit for setting a time interval (0 – 10 sec.) between stop-restart actions to prevent the motor and other internal components from overheating. It is recommended to set the restarting timer longer when the ambient temperature and/or the temperature of flow material is high.The restarting timer is factory-set to 1.5 sec.COMPONENT IDENTIFICATIONFigure 1.

Tightening with an excessive torque may damage the screw thread of the cap.Figure 6. Manual Drive ShaftINSTALLATIONThe following is an example of procedure for mounting the MSP unit to a bi-directional valve.The valve and components such as yoke necessary for the installation are to be provided by the customer. Be sure to remove power supply except when needed.1) Supply power voltage to the MSP and apply 0% (100% for direct action) input signal to move the output stem to its fully extended position.2) Set the valve stem at its lowest position.3) Attach the yoke to the MSP .4) Screw the valve stem into the output stem un-til there is little opening between them. For applying a sealing pressure, refer to Table 4 and screw it until the opening equals the contraction (e.g. 0.5 mm for MSP4-x3) that corresponds to the sealing pres-sure.5) Fix the both stems with a lock nut.6) Supply power voltage to the MSP and apply ap-prox. 50% input signal, and ensure that the gap be-tween the yoke and the valve bonnet has been closed. Fix the yoke and the valve.7) Connect the position indicator and other components as needed.Note: When mounting an MSP6 unit (24V AC model) usingM-Systems’s yoke set (model:YSS, for Japan sales only), refer to Instruction Manual (NM-4893) of theyoke set for the installation procedure.Figure 7.

Otherwise it could cause breakdown. M-System is not liable for any malfunction or inconvenience caused by unauthorized changes made by the user.■DIRECT/REVERSE ACTION AND OPERATION AT AB-NORMALL Y LOW INPUTThe actuator action is factory set to “Reverse” (i.e. the out-put stem goes up as the input signal increases.), and the operation at abnormality to “Go down.”For changing the setting, use the DI P SW on the control PCB referring to Tables 2 and 3.Table 2. Switching ActionsACTION SW1-3EXPLANATIONSDirect ON Output stem goes up as the inputsignal decreases.(Valve stem extended)Reverse OFF Output stem goes down as theinput signal decreases.(Valve stem retracted)Table 3. Operations at Abnormally Low InputOPERATION SW1-1SW1-2Stop– *1ON Go down/Extend OFF OFFGo up/Retract ON OFF*1. The setting of SW1-1 is disregarded in Stop mode.Note 1: SW1-4 is not used.Note 2: I n ‘Direct’ action, the position output is 5 – 1V DC proportional to the input 0 – 100%.■ORDER OF ADJUSTMENTSAfter installation, perform adjustments in the order of: zero; span; seal-spring; and sensitivity (deadband). Lastly, adjust the limit switches for optional full-open and full-closed signals.The following explanation applies to ‘Reverse’ action. For ‘Direct’ action, read the values in the brackets [ ]. Note: A pplying an over-torque to the adjusters may dam-age the threads or destroy stoppers. Use a small-sizedscrewdriver and be sure to stop turning as soon as theyhit the stoppers.■ADJUSTMENT PROCEDUREA) Zero and Span• Supply power voltage to the MSP and apply 0% [100%] input. Turn Zero adjuster to adjust the lower-end or fully-extended position of the output stem (valve stem retracted) to a desired position. Alternatively, adjust the connecting section of the stems. For applying a sealing pressure, refer to Table 4 and screw it until the opening equals the contraction that cor-responds to the sealing pressure.• While applying 100% [0%] input, turn the Span adjuster until the output stem reaches a desired upper-end or ful-ly-retracted position (valve stem extended).F or three-way valves, the sealing pressure can be applied also in the direction in which the output stem goes up*2. Refer to the procedure for Zero adjustment.• While applying 0% [100%] input again, check that the output stem reaches the fully-extended position. If the position is shifted, go through the above procedure again.Note 1: T he MSP is designed so as to minimize an influence of Span adjustment on the Zero position.That is, the lower-end position of the output stem ishardly displaced when Span adjuster is manipulated. Note 2: N arrower stroke is more likely to cause huntingi.e. the motor frequently changes rotation direction.Adjust Deadband in such a case.*2.

MSPSCompanies may be wary of trusting third-party service providers with their data and access to their systems. It may be necessary to ensure prospective MSPs and MSSPs comply with frameworks like SSAE-16 or AT101 (repackaged as SOC 1 and SOC 2 Reports).2. NEW PLAYERS ARE EMERGINGValue-Added Resellers (VARs) traditionally sold hardware systems to companies, which may also have included a software element. They are similar to MSPs and MSSPs in that they possess the technical expertise to serve a customer’s needs. Many VARs may even receive requests from their current customers to include services like a firewall or network monitoring, and instead of outsourcing the demand, now choose to provide it themselves. Either they have the expertise, or they partner with an expert service provider already.These similarities mean many VARs are actively changing their business model to that of an MSP. It requires a relatively small shift in focus from delivering a technical product to providing a technical service. Implementing a customer service process model and improving the support services offered by a VAR goes a long way to moving into the MSP space.VARs have years of technical expertise deliveringhardware systems to their customers while making useCHAPTER 1: INTRODUCTION1. THE MANAGED SERVICES PROVIDERS MARKETThere are still challenges facing the industry though. Foremost of which is the skills gap in the sector. IT firms are recruiting the best technicians and engineers, but the rapid rate at which new technology is developed requires additional skills and training to be provided to existing IT staff members.Additionally, maintaining systems that are becoming more complex every year is consuming a moresubstantial portion of IT budgets for companies, capping their expenditures.of service providers themselves. They can easily expand their offerings to include a complete end-to-end solution, something customers desire more often.3. IT MSP STATISTICS ARE MOSTLY FAVORABLEThe demand for Technology and Managed IT Services is growing daily. From large enterprises to small and medium companies, everybody is dependent on the latest technology systems to succeed in the business world. IT budgets rarely increase though, so companies are always looking to do more while spending less.With MSPs and MSSPs at the forefront of this technology drive, the industry has favorable forecasts for the future.Some vital statistics on the industry include:Overall IT Industry growth expected to be 5% per year Of all the digital data in use today, 90% was created in the last two yearsAnnually 75% of SMBs will outsource some of their IT requirements to MSPsNew customers will make up 48% of the market’s growthMachine Learning, Blockchain, and the Internet of Things (IoT) are the leading new technologies Top skills sought by customers are for DataManagement and IoT4. SOLUTIONS FOR SMALL-TO-MEDIUM BUSINESSMSPs/MSSPs are becoming more critical to SMBs as they seek to grow and thrive in their respective markets. Having their IT needs catered to in-house has become expensive and laborious. Both resources and equipment (including technical expertise) can quickly become outdated and upgrades to new systems slow due to operational constraints.A smart solution to the above problem is to farm out a larger portion of the operational IT systems to a service provider.The primary services requested are:Storage, backup, and disaster recovery servicesNetwork Monitoring (Firewalls, Intrusion Detectionand Prevention Systems)Security (Antivirus and Malware protection)VOIP Telephony servicesSoftware-as-a-Service (Saas)Knowing what SMBs need makes it possible for MSPs and MSSPs to bundle solutions that specifically cater to small-and-medium businesses. Their budgets can therefore cover their IT needs, while upgrades and automating additional business tasks remains possible without causing as many operational disruptions.CHAPTER 2: MOVING INTO CYBERSECURITY CAN BE DAUNTING1. CHOOSING THE RIGHT SOLUTIONSA comprehensive cybersecurity solution will primarily include:earliest opportunity. By proactively sourcing solutions that cater to your customers’ security needs, you can become the one-stop-shop for both hardware products and managed IT cybersecurity solutions.Adding managed security services to your portfolio will also increase your revenue stream and improve your client relationships. The managed security services market will grow to more than $35 billion in 2020. As an MSSP, you are the security professional protecting clients from major data breach threats like phishing, malware, trojans, and work proactively with the client to ensure all systems and devices are adequately protected.Enforcing password policies (revoking and forcing password changes regularly)Data backups and virus protectionMultifactor Identification and AuthenticationDue to the rapid increase in cyberattacks, it is critical that as an MSP you have the right alerting tools in place to protect clients and their networks. Finding out too late that a phishing email slipped through or a device began acting suspiciously can lead to a breach and devastating results for you and your client. MSPs should ensure that the solutions they choose have 24/7 alerting engines that can be integrated into their Remote Monitoring and Management (RMM) or apps like PagerDuty or Slack.2. MSPS TO MSSPS – SECURITY-SPECIFIC SOLUTIONSAn MSP may want to include security services or start making use of security-specific service providers to augment its customer offerings. This makes sense asMSSPs focus exclusively on data and network safety. They provide state-of-the-art firewalls boosted with Intrusion Prevention and Detection Systems (IPDS) that are sophisticated enough to prevent real-time attacks.Similarly, if you are a VAR thinking of aligning your business model with that of an MSP, it makes sense toinclude cybersecurity services for your customers at theCloud Options - Everyone is moving to the cloud, and your customers will be curious about this option too. Choose a solution that has cloud-based options that can scale as you grow.Whatever solution you choose, it will be important that it can integrate with current technologies and software applications. The most significant benefit of doing this is the convenience you offer to your customers. They will not have to seek additional service providers to ensure their overall security. That simplifies their lives andboosts your attractiveness for any future business needs they may have.3. EVALUATING SOLUTIONSWhen determining which solutions to add to your MSP portfolio to offer MSSP services, you can get boggeddown with the amount of options to choose from. Follow these tips to ensure you select the right vendor that can benefit your business and clients.Find a Comprehensive Solution - You don’t want a solution that only addresses a few aspects of network security. Solutions should have threat and malware protection as well as block phishing and hacking attempts. Look for solutions that alsoencompass cyber threat intelligence to protect againstemerging and unknown threats.Price is Important - Many of your customer will probably not be able to afford high-end solutions, which is the reason they are coming to you for help. Make sure the solution you choose has SMB pricing inmind so you can pass those savings on to the client.Alerts & Reporting are Critical - Being able to easily pull reports to determine the root cause of an attack or showcase compliance efforts for those clients with egulations to abide by is a critical feature you should look for when deciding on a network security vendor to partner with. A solution with real-time alerts is also crucial if you want topatch a vulnerability or stop a threat from reaching users.CHAPTER 3: FOCUSING YOUR SECURITY REQUIREMENTS1. COVERING THE BASICS2. CHOOSING A CYBERSECURITY PARTNERKey considerations when selecting a cybersecurity partner will include:Deployment and implementation requirementsIndustry knowledge and expertiseSupport and remote management capabilitiesSystem customization and integration featuresThe items above should all form part of the assessment before choosing a partner. The best cybersecurity solutions will consider these pain points and eliminate most of them for you.3.

6、中断应用程序举例（外部中断）:
void interrupt_initial() { P1DIR&=~BIT7; //P1.7为输入 P1IE|=0x80; //P1.7中断允许 P1IES|=0x00; //P1.7上升沿触发 P1IFG=0; //P1.7中断标志清除,对于多源中断必须先清中断标志再打开中断 _EINT(); //总中断允许 } #pragma vector=PORT1_VECTOR __interrupt void Port_1(void) { P1IFG&=~BIT7; //P1.7中断标志清除 /*在此写中断服务子程序*/ }

4、定时
一、常见的定时方式：
1、软件定时：通过延时程序实现。缺点：在延时期间，CPU一直被占用，浪费 了CPU的利用率，而且延时时间不好计算。
2、硬件延时：通过专门的定时器件实现。优点：在简单的软件控制下，产生准 确的延时。
二、硬件定时器种类：
1、看门狗定时器。 2、定时器A。 3、定时器B。 4、实时时钟RTC。
第12页/共48页
5、中断的嵌套：
当同时有多个中断来的时候才有优先级的考虑（优先级顺序可查看向量表）
实现中断嵌套需要注意以下几点： 1）430默认的是关闭中断嵌套的，一定要中断嵌套的话，就必须在中断服务程序中打开总
中断 msp430的指令中，_DINT()和_EINT()分别指关和开总中断。 2）当进入中断服务程序时，只要不在中断服务程序中再次开中断，则总中断是关闭的， 此时来中断不管是比当前中断的优先级高还是低都不执行； 3）若在中断服务程序A中开了总中断，则可以响应后来的中断B（不管B的优先级比A高 还是低），B执行完再继续执行A。注意：进入中断服务程序B后总中断同样也会关闭， 如 果B中断程序执行时需响应中断C，则此时也要开总中断，若不需响应中断，则不 用开中断，B执行完后跳出中断程序进入A程序时，总中断会自动打开； 4）若在中断服务程序中开了总中断，后来的中断同时有多个，则会按优先级来执行，即 中断优先级只有在多个中断同时到来时才起做用！中断服务不执行抢先原则。 5）对于单源中断,只要响应中断,系统硬件自动清中断标志位,对于TA/TB定时器的比较/捕 获中断,只要访问TAIV/TBIV,标志位倍被自动清除;

看门狗定时器： 看门狗定时器实际上是一个特殊的定时器，它的的功能是当 程序运行发生故障时序时能使系统从新启动。 其原理就是发生的故障的时间满足规定的定时时间后，产生 一个非屏蔽中断，使系统的复位。这样当在调试程序或预计 程序运行在某段内部可能瞬时发生时序错误时（如外部电路 干扰）选用设置看门狗定时中断可以避免程序跑飞 看门狗的定时时间可以通过WDTCTL中的低三位（SSEL、IS1、IS0）选择，当 系统时钟为1MHz时，最大可设置为1秒钟，最小可设置64微秒。 WDTCTL是一个16位寄存器，其高字节为口令，口令为5AH，当对它写入操作 时必须写口令才能操作，否则会导致系统复位。 另外该模块还具有定时器的功能。你可通过TMSET位进行选择。你可通过设置 CNTCL来使WDTCNT从0开始计数。其定时按选定的时间周期产生中断请求。 当WDT工作在定时器模式时，WDTCTL中断标志位在定时间到时置位，因该模 式下定时器中断源是单源的，当得到中断服务时其WDTCTL标志位复位。 EXIT
1、 异步通讯的模式结构。在异步模式下，接收器自身实现帧的同步，外部的通讯设
备并不使用这一时钟。波特率的产生是在本地完成的。异步帧格式由1个起始位、7或8个数 据位、校验位（奇/偶/无）、1个地址位、和1或2个停止位。一般最小帧为9个位，最大为 13位。 2、 波特率发生器：MSP430的波特率发生器是根据波特率选择寄存器UBR和调整寄存 器UM来产生的串行数据位，因此在设置上非常灵活， 波特率=模块时钟/分频因子=UBR+UM/8 波特率：指每秒传送的位。 分频因子：是指在特定的波特率下，每传送一位数据所需要的 时钟周期，用N表示。 3、UBR和UM寄存器的装载数据的确定 UBR是一个16位的寄存器，它分两个8位寄存器来设顶定，UBR00和UBR10 注意他们的高低直接字节，使用时是按字节操作。 例如：波特率=2400， 模块时钟=32768Hz ，其分频因子为13.65 由于分频因子不一定正好为整数，因此对小数部分必须通过调整寄存器来进行调整，在此 可插进5个“1”来满足一帧数据的65%的误差。但即使这样也不可能完全消除这种误差，只 是误差很小可忽略不计，这样才能准确的进行数据传送。 EXIT

基本定时器的作用：MSP430F4XX系列的器件增加了一个基本定时器模块。 它主要的作用是产生一个低频控制时钟源来供给LCD 显示模 块。同时它又是一个定时器，其定时的时间可根据控制寄存 器选择，一般用做产生时钟信号（如秒信号） 结构：
擦除操作：要对FLASH存储器写入数据，首先要擦除将被写入的段，而且是 全部擦除该段。经过一次擦除后该段所有位为1。擦除可以对一段、几段或整个模 块进行。 顺序： 1、选择适当的时钟和分频因子，其目的为时序发生器提供输入时钟
2、将 LOCK=0，后判断BUSY是否为0，为0时执行下一步 3、擦除一段将ERASE置为位，擦除多段擦除时，则将MERASE置位。如 擦除整个模块则将两位都置一。 4、对要擦除地址范围内任意位置进行一次空写操作。如CLR &XXXH 写操作：顺序 1、 2、3、 同上 4、如果写入单字节或单字，将控制位EWRT置位，如果在指定的段进行 或多字、多字节顺序的写入，则将WRT和BLKWRT同时置位。 此时启动了时许序发生器后数据在时序发生器的控制下完成写入。 读操作：可在任意时间访问该数据，不需要设置。

I/O端口使用练习： 程序示例：参见教学光盘行扫描键盘程序。 该程序采用查询法不断的对行扫描来确定键盘的按键位置。 本学习板采用三行四列口线，做成对应一个从0到9的数字键盘。 开始时将行口线设置输出方向并置位，列口线设置为输入方向。 首先将要查第一行口线复位，循环检查列口线是否有置低，没有继 续将第二行口线复位，循环检查列口线是否有置低，这样就会得到 按键按下的位置。 在使用时注意参照电路原理图将相应的跳线设置正确即可。 运行该程序你会发现你所按的数字会显示在LCD上。 你也可以修改它如采用中断查询的方式。

FLASH存储器根据器件型号不同其容量不同，所在的空间也会不 同，它是按段来定义它们的大小。每段为512个字节，从高字FFFFH开始 为0段，依次向下为1、2、3…段到N段。 而信息存储器的段和地址固定为 1000H~10FFH并分A和B，每段为128个字节。 FLASH主要作用是存放程序代码、数据表格和用户信息等。你可以多 次通过JTAG进行擦写，也可在系统运行随时进行写入。 对FLASH存储器的写入必须是整段进行，可以进行多段的擦除，但不 能一个字节一个字节擦除，擦除后该位为1。 对FLASH的操作是通过三个寄存器来实现。 FCTL1、FCTL2、FCTL3 FLASH在擦写和编程是通过列通过地址锁存器和数据锁存器与总线连接。 锁存器的信号来源于时序发生器，对编程电压来自编程电压发生器。 三个控制寄存器控制位控制产生所需的时序信号。 EXIT

硬件乘法器： 具有硬件乘法器的器件有F14X和F44X系列，它独立于CPU，并通过内部 总线与CPU相连接。它能实现16×16、8 ×16、8 ×8运算，支持无符号数乘 （MPY）、有符号数乘（MPYS）、无符号乘加（MAC）、有符号数乘加 （MACS）。 做乘法时要将第一个操作数写在前面，在写第二个操作数。在写第一个 操作数一定是MPY、MPYS、MAC、MACS，第二操作数一定是OP_2，否则 不会作乘法操作。 当将两个数据写好后执行乘法以后其结果立即保存在紧接的乘积寄存器 RESL0、RESL1中。这是一个32位寄存器。 总结乘法过程：写第一个操作数就确定了运算类型。 写第二个操作数写完乘法立即进行。 乘积存放在32位寄存器中。 注意：不能用在容易重叠的场合，否则结果不正确。使用时必须要有硬 件这个器件件。 EXIT

MSP430的液晶驱动模块：
具有液晶驱动模块的MSP430有4XXX系列，如413、435、449等。 提供液晶驱动时钟源信号是靠选择基本定时器的控制寄存器相应的位（FRFQ1、FRFQ0）来实现的。该 位可选择4钟输出作为LCD的时钟频率。并通过外部引脚引入的直流电压来作为模拟电压发生器的能源。 液晶的工作原理：LCD液晶玻璃片是一种极低功耗的显示器件，在袖珍式仪器仪表中应用较为普遍。它的 结构如图所示： 液晶的两个极板等效一个电容，两个电 极板分别为公共极和段极。这里公共极 由COM n信号驱动。 如果在上下两极板加有交边变的电压后，使之内部液晶分子由平行排列变成垂直排列后入射的偏镇振光失 去旋光性呈黑色，这样我们根据需要作成各种文字、数字或图形就回通过它显示出来。一般LCD做好以后， 驱动的方式是固定的，常见的方式有静态和时分割（电压平均化）两种。MSP430采用的是这两种。其偏 有1/2、1/3、 ¼，因此工作时最多有4个COM公共电极，在具体使用时，独立字符、独立图形和独立数 码显示的笔画（通常数字用7段笔画表示）占有一个段，而MSP430的外部引脚的多少就与这些段和COM 使的个数有关。如果超出了使用范围，一是减少段，二是增加COM。MSP430内部有20个显示缓存单元， 每个显示缓存单元的字节中的位与LCD的段一一对应，在实际使用中，每个缓存单元中的位并非全部使用， 这主要与COM使用的个数有关。例如显示7段笔画数字，静态需要4个缓存单元，2COM需要2个缓存单元 3个COM需要1.5个缓存单元。而4COM需要1个缓寻存单元。
