Freescale 16-bit MC9S12HY64 自动汽车仪表盘演示板用户指南说明书

Freescale Semiconductor Users GuideDocument Number:S12HY64ACDUGRev. 2, 12/2009 Contents1Demonstration BoardHardwareThe dashboard is developed with Freescale’s low cost 16-bit microcontroller the MC9S12HY, which is responsible for driving all the board functionality. The hardware comes complete with four motors that are shaft-illuminated (providing an aesthetic back-light for the needle pointers), a160-segment LCD display, molex CAN and LIN connections, a piezoelectric speaker to demonstrate sound capability, and a series of switches and LEDs to emulate standard dashboard functionality.1Demonstration Board Hardware . . . . . . . . . . . . . . . . . . . 1 2How to Set Up and Operate the Demo . . . . . . . . . . . . . . 2 3FAQs and Talking Points. . . . . . . . . . . . . . . . . . . . . . . . . 4 4Additional Resources and Materials . . . . . . . . . . . . . . . . 5MC9S12HY64 Automotive Cluster Demo Users Guideby:Steven McLaughlinApplications EngineerMicrocontroller Solutions Group, ScotlandHow to Set Up and Operate the DemoFigure1. MC9S12HY Dashboard Cluster Demo Board2How to Set Up and Operate the DemoThe demo is very straightforward to set up. It requires a 12 V DC supply, which is connected at the bottom right-hand side of the board, as shown in Figure1. Switch three should be set to the on position. (This demo does not use switch two, the ignition switch, so it can be in any state.) The demo will then start automatically in the initialization phase (described below) and all motors will return to zero all at once.How to Set Up and Operate the DemoFigure 2. Flow Diagram (With Pictures) of Demo OperationPower upInitialization phase:LCD displaysMotors return tozero position“S12HY”Buttons can initiate indicator LED, scroll to trip A/B screens,enter hazard mode — Potentiometer adjusts sound All modules moveat different speedsin clockwise andcounter-clockwisedirection and the LCDupdates varioussegmentsvolumeFAQs and Talking PointsBesides driving the motors and LCD, the demo incorporates some software solutions that enhance functionality.1.Pressing switch 5 activates a horn sound and pressing switch 4 toggles the cruise control on and off.2.Pressing the menu switch allows the user to scroll through the odometer, trip A meter, and trip Bmeter. This is indicated clearly on the LCD, and the user will also see the digits change.3.By pressing switch 4 and 5 simultaneously, the demo will enter hazard mode, shut down theoperation, enable an alarm sound, and begin to flash and display “hazard” on the LCD. Release the switches to return the demo to normal operation.4.The piezoelectric speaker plays a continuous indicator relay clicking sound. Turning thepotentiometer varies the amplitude of the PWM signal that is fed to the piezoelectric speaker. Further incorporated into this demo are two significant software solutions. First, it should be noted that the MC9S12HY does not contain a hardware stepper stall detect module (SSD), which means that the motor cannot detect the zero position and cannot determine when the end of travel has been reached. But this demo is capable of both — an integrated driver capable of performing stall detect with microstepping is used to enhance the motor functionality for these purposes.Second, the user will notice that the odometer value displayed on the LCD is maintained even after powering the demo off and then back on, despite the MC9S12HY device having no EEPROM. The demo uses an emulated EEPROM software driver, available for free on the Freescale website, which uses the device’s D-flash to read and write the odometer values.3FAQs and Talking Points1.Is the SSD software available for general use?—An application note, AN4024 has been released explaining the SSD software technique and is available with demo software.2.Only the odometer value is restored at POR — why aren’t the other values restored?—This application is for demonstration purposes, so only the odometer value has been programmed with the EEE driver. In a production application other values, such as the trip A/Bmeter, can be implemented in the same way.3.How are the shaft pointers illuminated?—Each motor includes an integrated white LED which is connected directly to a GPIO. (It should be pointed out that these require one GPIO each.) Shafts are illuminated by controlling theGPIO in a manner normally used for initiating LEDs.4.What is Jellyfish?—This is the internal code name for this device, which is why a jellyfish symbol and the word “Jellyfish” appear on the LCD screen.5.There are a number of other components that do not seem to be used, as well as somenon-populated components. What are they?—The non-populated components are for the 32-bit MPC5606S device. This board was built witha footprint for both MPC5606S (found on the underside of the board) and MC9S12HY. This isAdditional Resources and Materials why some LEDs and potentiometers do not operate with this demo: the MC9S12HY does notsupport them.6.The demo board contains a CAN and LIN molex connector. Do these work?—Yes, but they have not been enabled on this demo.7.Where can I find the schematics of the demo, and is there demo code available?—Axiom will provide a CD with both schematics and software when you purchase the board. The firmware for this demo is not openly available.8.Is it possible to have a backlit LCD?—It is not included on this demo, but it is possible. However, it may be difficult to implement if the LCD has already been soldered to the board. The backlight requires a 5 V DC power supplyand a GPIO has been made available on this demo for this purpose.9. I see a connection for auxiliary motors on the left-hand side of the board — what is it for?—This connector allows the connection of additional motors, but is not available for the MC9S12HY (which can drive a maximum of only four motors). It is for the MPC5606S only.10.If I don’t like the piezoelectric speaker sound, can I change it?—Yes. This is a PWM signal being fed via an amplifier, and it is possible to alter it.4Additional Resources and MaterialsApplication notes available at :•Application note titled Introduction to the Stepper Stall Detector Module (document AN3330).•Application note titled Comparison of the S12XS CRG Module with S12P CPMU Module (document AN3622) gives an explanation of the CPMU clock module.•Application note titled High Speed Stall Dtection on the S12HY Family (document AN4024).•Application note titled MC9S12HY Family Demonstration Lab Training (document AN4021).

飞思卡尔16位MCUMC9S12P-系列参考手册飞思卡尔16位MCU MC9S12P-系列参考手册详情请下载： 16位MC9S12P－Family.pdfThe MC9S12P family is an optimized, automotive, 16-bit microcontroller product line focused on lowcost,high-performance, and low pin-count. This family is intended to bridge between high-end 8-bit microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS family. The MC9S12P family is targeted at generic automotive applications requiring CAN or LIN/J2602 communication. Typical examples of these applications include body controllers, occupant detection, door modules, seat controllers, RKE receivers, smart actuators, lighting modules, and smart junction boxes.The MC9S12P family uses many of the same features found on the MC9S12XS family, including errorcorrection code (ECC) on flash memory, a separate data-flash module for diagnostic or data storage, a fastanalog-to-digital converter (ATD) and a frequency modulated phase locked loop (IPLL) that improves theEMC performance.The MC9S12P family deliver all the advantages and efficiencies of a 16-bit MCU while retaining the lowcost, power consumption, EMC, and code-size efficiency advantages currently enjoyed by users of Freescale’s existing 8-bit and 16-bit MCU families. Like the MC9S12XS family, the MC9S12P family run 16-bit wide accesses without wait states for all peripherals and memories. The MC9S12P family is available in 80-pin QFP, 64-pin LQFP, and 48-pin QFN package options and aims to maximize pin compatibility with the MC9S12XS family. Inaddition to the I/O ports available in each module, further I/O ports are available with interrupt capability allowing wake-up from stop or wait modes.。

ESD damage is not a warranty repair item.2) Axiom Manufacturing does not assume any liability arising out of the application or use ofany product or circuit described herein; neither does it convey any license under patent rights or the rights of others.3) EMC Information on the TWR-S12G128 board:a) This product as shipped from the factory with associated power supplies and cables,has been verified to meet with requirements of CE and the FCC as a CLASS A product.b) This product is designed and intended for use as a development platform for hardwareor software in an educational or professional laboratory.c) In a domestic environment, this product may cause radio interference in which case theuser may be required to take adequate prevention measures.d) Attaching additional wiring to this product or modifying the products operation from thefactory default as shipped may effect its performance and cause interference with nearby electronic equipment. If such interference is detected, suitable mitigating measures should be taken.TERMINOLOGYThis development module utilizes option select jumpers to configure default board operation. Terminology for application of the option jumpers is as follows:Jumper – a plastic shunt that connects 2 terminals electricallyJumper on, in, or installed = jumper is a plastic shunt that fits across 2 pins and the shunt is installed so that the 2 pins are connected with the shunt.Jumper off, out, or idle = jumper or shunt is installed so that only 1 pin holds the shunt, no 2 pins are connected, or jumper is removed. It is recommended that the jumpers be placed idle by installing on 1 pin so they will not be lost.Cut-Trace – a circuit trace connection between component pads. The circuit trace may be cut using a knife to break the default connection. To reconnect the circuit, simply install a suitably sized 0-ohm resistor or attach a wire across the pads.Signal names followed by an asterisk (*) denote active-low signals.FEATURESThe TWR-S12G128 is a demonstration board for the MC9S12G128 microcontroller; an automotive, 16-bit microcontroller focused on low-cost, high-performance in a low pin-count device. The MC9S12G128 provides16-bit wide accesses, without wait states, for all peripherals and memories. The MC9S12G128 targets automotive applications requiring CAN or LIN/J2602 communications. Examples include body controllers, occupant detection, etc… The board is designed to interface to the Freescale Tower System, a modular development platform which aids in rapid prototyping and tool-reuse. An integrated Open-Source BDM, software tools, and examples provided with the development board make application development and debug quick and easy.

CodeWarrior Development Studio is supplied with this board for application development and debug. Refer to the supporting CodeWarrior documentation for details on use and capabilities.DEVELOPMENT SUPPORTApplication development and debug for the target TWR-S12 board is supported through the Open-Source Background Debug Mode (OSBDM) interface or an external BDM interface connector. The OSBDM is fully supported in CodeWarrior and provides direct, non-intrusive access to the target device internals. While in BDM mode, no internal resources are used. Code stepping and break-points are fully supported.Connection between a host PC and the target device is provided via a mini-B, USB connector. The OSBDM is capable of providing power to the target board eliminating the need for external power. Please note that power supplied by the OSBDM is limited by the USB specification. When powered through the OSBDM, total current draw, including the OSBDM, TWR-S12 board, and Tower System must remain less that 500mA. Otherwise, the USB bus will cause the host PC to disconnect the board. Damage to the host PC, target board, or Tower System may result if this current limit is violated.OSBDM BootloaderThe OSBDM is pre-programmed with a bootloader application to allow field updates. The USB bootloader communicates with a GUI application running on a host PC. The GUI application allows the user to update OSBDM firmware easily and quickly. Option jumper JP401 enables the bootloader at startup. This option header is not populated in default configuration. Refer to Freescale Application Note AN3561 for details on using the GUI application and bootloader. The application note may be found at or at /support. BDM_PORT HeaderA compatible HCS12 BDM cable can also be attached to the 6-pin BDM interface header at J3. This header allows the use of external programming/debug cables. Refer to the external programming/debug cable documentation for details on use. The figure below shows the pin-out for the DEBUG header.Figure 2: BDM_PORT HeaderJ4001 2 GND See the associated RM for complete DEBUGdocumentation3 4 RESET*5 6 VDDNOTE: This header is not installed in default configuration.POWERThe TWR-S12 board may be powered from the OSBDM, from the Tower System, from the LIN +V input, or 2 input vias at E1 & E2. The LIN +V input accepts +12V from the LIN bus and uses an on-board regulator to create the board operating voltage. Input vias at E1 & E2 allowconnecting external power to the board if desired. An on-board regulator is used to create the board operating voltage from this input.Use of the on-board regulator requires input voltage between +7.V and +27V. However, input voltage should be kept as low as possible to reduce device self-heating.Power SelectOption headers PWR_SEL selects the input power source for the target board. When powered from the Tower System, the OSBDM voltage output is disabled.Figure 3: PWR_SEL Option HeaderJP5 1●●2Select TWR voltage inputPWR_SEL ●●Select OSBDM voltage input (default)●●Select on-board regulator inputRESET SWITCHThe RESET switch applies an asynchronous RESET input to the MCU. The RESET switch is connected directly to the RESET* input on the MCU. Pressing the RESET switch applies a low voltage level to the RESET* input. A pull-up bias resistor allows normal MCU operation. LOW VOLTAGE RESETThe MC9S12G128 applies a Power-On Reset (POR) circuit and an internal Low Voltage Reset (LVR) circuit to ensure proper device operation. The POR circuit holds the MCU in reset until applied voltage reaches an appropriate level. The LVR forces the device into reset if input voltage falls too low, protecting against brown-out conditions. A user configurable Low-Voltage Detect (LVD) with interrupt output is also available. Consult the MC9S12G128 reference manual for details of POR, LVR, and LVD operation.TIMINGThe TWR-S12G128 internal timing source is active from RESET by default. An external 8MHz crystal oscillator, configured for low-power operation, is also installed. Refer to the target device RM for details on selecting and configuring the desired timing source.COMMUNICATIONSCommunications options for the TWR-S12G128 include serial RS-232, LIN, and CAN. Serial RS-232 communications is supported through a RS-232 physical layer device (PHY) and a 2x5 pin header. A high-speed, enhanced, LIN PHY provides LIN bus communications through a 2x2 Molex connector (pn 39-29-1048). A high-speed CAN PHY provides CAN bus communications through a 1 x 4 Molex connector (pn 39-30-3045).Connecting LIN cables require Molex housing, pn 39-01-2040 and pins, pn 39-00-0217. Connecting CAN cables require Molex housing, pn 39-01-4040, and pins, pn 39-00-0217.The COM_SEL option header connects the MCU SCI signal to either the LIN PHY or the RS-232 PHY. See Figure 6 below for jumper position options. See Figure 4 below for jumper position options.RS-232The TWR-S12G128 applies the MAX3387E, RS-232 transceiver to support serial communications. A standard 2x5 “Berg” pin-header on 0.1” centers and an IDC to DB9 cable supports connecting standard serial cables to the target board. Figure 4 below shows the SCI signal connections.Figure 4: Serial ConnectionsNOTE: For normal RS-232 operation, FORCEOFF* should be actively driven to the high level.Alternately, open CT5 to allow FORCEOFF* to float high.COM ConnectcorA 2x5, 0.1”, standard “Berg” pin-header provides external connections for the SCI port. Figure5 below shows the COM1 pin-out.Figure 5: COM1 Connector2, 71, 7TXD CTSRXD RTS1, 2 TP2GND NCCOM_ENThe COM_EN option header connects the MCU SCI port to either the SCI PHY or the LIN PHY.

Figure 6: COM_EN Option HeaderConnects target MCU SCI port to LIN PHY to enable LIN buscommunicationsConnects target MCU SCI port to RS-232 PHY to enable serialcommunicationsLIN PortThe TWR-S12G128 applies the MC33661 LIN bus physical layer device (transceiver) to support LIN communications. The PHY may be configured as a Master or Slave node on the LIN bus. LIN connectors J9 & J10 are configured in parallel to support pass-thru signaling. Figure 7 shows the LIN block diagram.Figure 7: LIN Block DiagramThe LIN interface provides optional features of slew rate control, network supply, and wake up option. Refer to the MC33661 Reference Manual for detail on PHY functionality. The following sections detail functionality for LIN option jumpers.LIN EnableThe LIN PHY is enabled by default. Disable the PHY by connecting the test point, TP3, to GND.LIN COM InputLIN inputs RX and TX are selectable using the COM_EN option header. Refer to Figure 6 above for details on configuring this header.LIN_PWR OptionThe LIN_PWR option jumper connects pin 1 of both LIN connectors to the +V input. In Master mode, this option may be used to power LIN slave devices. This option requires +12V be applied at E1/E2 inputs. In Slave mode, this option allows slave device to draw power from the LIN network. For Slave mode configuration, external power should not be applied to the target board. LIN_PWR is enabled by installing a shunt from JP3-1 to JP3-2. Refer to Figure 8 below.MSTR OptionThe MSTR option jumper allows the LIN transceiver to be configured for Master mode functionality. Master mode may also be set using the INH pin on the PHY. Refer to the MC33661 device datasheet for details on use and configuration. Refer to Figure 8 below.Figure 8: JP6 Option HeaderJP3Connects LIN bus to +V input (default)LIN_PWR Enables LIN Master mode functionality (default)NOTE: LIN PHY may also be configured as a Master Node using the INH pin. Refer to the LINPHY data sheet for details.LIN-J1 ConnectorThe TWR-S12G128 supports two, 2 x 2 Molex connectors to interface to the LIN bus. Figure 9 below details the pin-out of the LIN bus connector.

The SPLIT output from each PHY is connected to the virtual ground providing common-mode stabilization. The differential CAN bus signal termination may be removed using option header JP13 or JP15. To prevent signal corruption, both option jumpers must be installed or both option jumpers must be removed. The CAN bus should not be operated with only 1 signal termination applied. Figure 11 below details the option header shunt positions.Figure 11: CAN Termination EnableEnables CANL termination1 2 Enables CANH terminationStandby ModeThe CAN PHY is configured for normal mode by default. To enable standby (STB) mode, apply a high logic level at test point TP1. Refer to the TJA1040T Reference Manual for use and capabilities of the Standby Mode.USER PERIPHERALSUser I/O includes 1 potentiometer, 4 push button switches, and 4 green LEDs for user I/O. The USER (JP14) option header enables or disables each User I/O function individually. The sections below provide details on user I/O. Figure 12 below shows the USER jumper settings.PotentiometerThe TWR-S12G128 target board applies a single-turn, 5K, ohm potentiometer (POT) to simulate analog input. The POT is connected to an ATD input on the target MCU and is decoupled to minimize noise transients during adjustment. Figure 12 below shows the USER jumper settings.User LED’sThe TWR-S12G128 target board applies 4, green, LEDs for output indication. Each LED is configured for active-low operation. A series, current-limit resistor prevents excessive diode current. Each LED is connected to a timer channel on the target MCU. Figure 12 below shows the USER jumper settings.Pushbutton SwitchesThe TWR-S12G128 provides 4 push-button switches for user input. Each push-button switch is configured for active-low operation and is connected to a key-wakeup input on the target MCU. No bias is applied to these push-button inputs and use of target MCU internal pull-ups is required for proper operation.

所有的 NVM 程序和擦除操作的时间基准由振荡器决定。要求最小振荡频率 f NVMOSC 能够运行程序和擦除操作。NVM 模式无法监测频率，所以无法防止程序和擦除操作在高于或低于指定最小频率上运行。尝试在低频率下的 NVM 模式下运行程序和擦除操作的话，程序的完整性和擦除的转换无法保障。 FLASH 和 EEPROM 的编程和擦除操作，是通过使用来自振荡器的时钟来计时，该振荡器分别使用了寄存器 FCLKDIV 和 ECLKDIV。时钟的频率必须被设置到 f NVMOP 指定的范围。

如何快速读懂并理解MC9S12XE系列的编程手册

如何快速读懂并理解MC9S12XE系列的编程手册在现今的经济社会，比拼的“快”不仅仅是速度快，更是效率高。

身处社会分工细致的今天，让自己更快效率更高是有方法的。

每一家MCU产商都会提供他们生产的MCU型号的datasheet,Reference Manual等各种说明手册。

这对于从事电子软件开发的人员来说，这是他们的第一手资料，也是他们最重要的参考资料，他们所有的软件设计工作都是参考手册上的内容，比如，硬件工程师可能比较在乎芯片的电气特性；MCU应用工程师关注外设，编程器时序开发人员则比较注重去理解Flash Module,在工作中他们要仔细并反复阅读他们所关注的部分。

最近则频繁的收到飞思卡尔芯片烧录不良的反馈，而且最多的集中在MC9S12XE这个系列上。

MC9S12XEP100这款飞思卡尔芯片跟平时我们所遇到的芯片相比有些特殊。

首先，它的Flash包括以下三部分：一、1MB的P-flash(Program Flash)，非易失性代码存储器；二、32KB的D-flash(Data Flash)，我们可以把它当作EEPROM；三、4KB的Buffer RAM。

其次，它三部分Flash特殊的地方：1）三部分Flash各部分分别映射在global Map的不同部分，并不是连续的。

所以对于所有的编写程序的工程师来说，要实现Flash Operations，首先要正确实现Flash Module 各部分的地址映射。

下图就是简单的一个映射说明：2）4KB的Buffer RAM。

虽然它就是一个RAM，但是它比较特殊，因为它的每次修改都会转储到D-Flash的一个分区中，每次上电会将该分区的内容自动加载到Buffer RAM中，所以它就是一个下电不丢失数据的RAM，我们就把它当作一个EEPROM。

MCU批量生产时的编程主要包括以下几部分，这里特别提醒做项目的工程师，烧录芯片是非常关键的，因为他包含了对整个MCU的Flash进行操作和加密：1）Flash 操作（编程、擦除、校验等）由于Buffer Ram的存在使得要实现Flash操作配置变得难度加大，因为对Buffer Ram的任何操作，最终都要更新到D-flash中的EEP中，所以在对Buffer Ram操作之前要对D-flash进行分区，分成D-flash和EEP两部分。

mc9s12xe系列单片机参考手册--中文1.3系统时钟介绍时钟和复位发生器模块（CRG）提供的核心和外设模块的所有内部时钟信号。

图1-8显示了从CRG所有模块的时钟连接。

在clock generation中查询CRG时钟产生的细节规范。

系统时钟可以提供多种方式，使系统的工作频率范围要支持：•片上锁相环（PLL）•锁相环自我时钟•振荡器由PLL或振荡器产生的时钟提供主系统时钟频率，核心时钟和总线时钟。

如图1-8所示，这些系统时钟用于驱动整个MCU的core，RAM，和外设。

闪存程序存储器和EEPROM可由总线时钟和振荡器时钟提供时钟信号。

“使用振荡器时钟作为时基，驱动程序，并提供NVM的擦除时间基准。

CAN模块可配置的时钟源来自总线时钟或直接从振荡器时钟。

这允许用户在提供的两种时钟信号的基础上，选择它的时钟性能。

为了确保时钟的存在，MCU包括一个片上时钟监视器，监视器连接到振荡器的输出。

时钟监视器可以被配置为调用PLL自震荡模式或在超过一定时间没有振荡器时钟出现，产生一次系统复位。

除了时钟监视器，MCU还提供了时钟质量检查模块执行时钟准确的检查。

时钟质量检查计数器在一个定义的时间窗口内检查预先设定了的时钟边沿，以确保时钟的正确运行。

检查程序可以被以下具体的事件调用，如唤醒或时钟监视器故障。

MCU可以处在不同的模式，而这与MCU资源的映射和总线接口配置操作相关。

这些内容将在1.4.1芯片配置摘要有提到。

MCU可以有不同的电源操作模式，当并不需要系统满负荷运行时，方便省电的模式是可选的。

这些内容将在1.4.2功率模式有提到。

1.4操作模式有些功能模块是可编程的，可以对某个模块进行冻结，而BGD模块的处于活动对于方便调试是有积极意义的，这在1.4.3冻结模式有提到。

对于系统的完整性，支持独立的系统状态功能，在1.4.4系统状态的说明有提到。

MCU有六个不同的模式而模式与系统资源配置相关。

不同的模式，ROMCTL与 EROMCTL在RESET信号的上升沿的状态，MCU的安全状态都会影响以下设备的特点：•外部总线接口配置•可能会影响Flash中的存储器映射，或不会•调试功能启用或禁用操作模式是由MODC，MODB和MODA在复位时的信号状态决定的。
