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 below shows the option jumper configuration for the COM_EN option header. 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.

A 4-pos, 4.22mm MOLEX connector interfaces to external CAN cabling. Differential input CAN signals, are terminated with 120 ohms. Option headers, JP13 and JP15 allow the user to optionally disconnect signal termination. Avalanche diodes protect the CAN PHY from voltage surges on the input differential signal lines. Figure 10 below shows the CAN connector pin-out.

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. Figure 12 below shows the USER jumper settings.Figure 12: JP1 Option HeaderSignal ON OFFPAD4/KWAD4/AN4 Enabled DisabledPAD5/KWAD5/AN5 Enabled DisabledPAD6/KWAD6/AN6 Enabled DisabledPAD7/KWAD7/AN7 Enabled DisabledPAD0/KWAD0/AN0 Enabled DisabledPT4/IOC4 Enabled DisabledPT5/IOC5 Enabled DisabledPT6/IOC6 Enabled DisabledPT7/IOC7 Enabled Disabled NOTE: User peripheral input/output is enabled by default.EDGE CONNECTOR PINOUTThe TWR-S12 board connects to the Freescale Tower System using the 2 PCIe Edge Connectors. Following the PCIe specification, the Bx signals are located on the top of the board and the Ax signals are located on bottom. Pin B1 for the primary and secondary connectors are at opposite ends of the board. The figures below show the pin-out of each edge connector.Figure 13: Primary Edge Connector5.0V Power Pri_B01 Pri_A01 5.0V PowerGround Pri_B02 Pri_A02 GroundPri_B03 Pri_A03Elevator Power Sense Pri_B04 Pri_A04Ground Pri_B05 Pri_A05 GroundGround Pri_B06 Pri_A06 GroundPS6/SCK0 Pri_B07 Pri_A07Pri_B08 Pri_A08PS7/API_EXTCLK/SS0 Pri_B09 Pri_A09 PD3Ground Pri_B49 Pri_A49 GroundPri_B50 Pri_A50 PA2Pri_B51 Pri_A51 PA3Pri_B52 Pri_A52 PA4Pri_B53 Pri_A53 PA5Pri_B54 Pri_A54 PA6Pri_B55 Pri_A55 PA7Pri_B56 Pri_A56Pri_B57 Pri_A57Figure 14: Secondary Edge ConnectorMISO1/KWJ0/PJ0 Sec_B11 Sec_A11Sec_B11ASec_B12 Sec_A12Sec_B13 Sec_A13Sec_B14 Sec_A14Sec_B15 Sec_A15PC1 Sec_B16 Sec_A16PC2 Sec_B17 Sec_A17 PC3PC4 Sec_B18 Sec_A18 PC5。

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。
