7、 modules.Thesemicrocontrollers are made available in surface mount packages with various numbers of physical pins.The number of pins usually does not allow all peripheral modules to be used simultaneously. Hardwareregisters on the microcontroller allow for configurable assignment of peripheral modul
8、e signals to physicalpins.This means that you have to select the proper device for your application and properly initializehardware registers from software.The purpose of the TASKING Pin Mapper is to assist you in performingthose tasks.1.1. Port PinThe basic entity of the TASKING Pin Mapper is the p
9、ort pin. Port pins are physical pins of the chip. A portpin name typically consists of a port identifier and, if the port identifier is shared by multiple pins, asequential pin number, for example TMS, AN4 or P10_2. A port pin name is not package specific. Eachpackage has its own specific assignment
10、 of port pin names to package pin numbers.The basic configuration item of a port pin is its function (which in most cases is determined by the signalassigned to it). Some ports have dedicated functions, mostly related to power supply or chip infrastructure.Other ports have configurable functionality
11、 (ultimately defined by run-time register settings).The requiredfunction is application specific.A port function definition consists of a symbolic name, a direction and a description.The TASKING PinMapper distinguishes between input functions and output functions. Functions are listed by their symbo
12、licnames (which are mostly signal names, for example ASCLK3).Port pins can have a number of other chip specific properties. Such properties can be fixed (for examplethe type of pad the port is connected to) or configurable (for example the pad state). Port pins are visiblein the Package view.You can
13、 assign a user-defined symbol name to the port pin and you can make thesymbol names visible in the Package view.You can use filters in pin selection views or you can useproperty values as background color codes in the Package view.You can change the configurable propertyvalues.1.2. PeripheralAURIX d
14、evices, such as the TC27xC, have support for several on-chip peripherals, such as serialcontrollers, timer units, and analog-to-digital converters.1.3. ConnectionThe TASKING Pin Mapper allows you to define connections between modules, where a module is eithera port pin or a peripheral.You can connec
15、t port pin modules to peripheral modules by selecting the pins Direction and its Chipinput function or its Chip output function.The peripheral module side of a connection is referred to as avirtual pin. Some peripheral modules can also be connected to other peripheral modules. Such a connection1is m
16、ade between two virtual pins.Virtual pins are internal to the chip and are not visible in the Packageview. However, virtual pin conflicts are reported in the Pin Conflicts view, for example when you try toconnect a GTM virtual output pin to a physical port pin and at the same time to a virtual input
17、 pin of anADC peripheral module.If you have defined a connection (either valid or invalid) the follow the connection button () becomesavailable and you can navigate from one side of the connection to the other side.This applies to virtualpins as well as physical pins.Virtual pins usually do not have
18、 a configurable direction.They are eitherInput or Output (and some virtual pins are bidirectional).See Section 2.3, Configuring the Pins for a step-by-step example.1.4. PackageWhen you create a new pin mapper document, as explained in Section 2.1, Adding a Pin Mapper Documentto an Existing Project,
19、you first select a processor (family), for example TC27XC, and a package, forexample BGA292.This selection defines the package pin numbers and the linking of package pins toport pins. It is possible that a port pin is linked to a single package pin multiple times by means of portpin aliases, for exa
20、mple AN39 and P40_9.For QFP (Quad Flat Package) type packages the pin number consists of the package identifier and asequential pin number. For BGA (Ball Grid Array) type packages the pin number consists of the packageidentifier and a matrix cell number.2Using the TASKING Pin Mapper for AURIXChapter
21、 2. Getting Started with the TASKINGPin MapperThe TASKING Pin Mapper is the graphical interface to configure the pins and modules in a package.2.1. Adding a Pin Mapper Document to an Existing ProjectTo configure the pins and modules of a package you need to create a project and add a Pin Mapperdocum
22、ent.1.If you have no existing C project, follow the steps to create a new C project, as explained in theGetting Started with the TASKING VX-toolset for TriCore.In the following steps we assume you have an existing TriCore TC27xC C project named myproject.2.From the File menu, select New TASKING Pin
23、Mapper Document.The New TASKING Pin Mapper Document wizard appears.3.Select the Project folder for the Pin Mapper document: type the name of your project (myproject)or click the Browse button to select a project.4.In the File name field, enter a name for the Pin Mapper document, for example myprojec
24、t.pincfgand click Next.The Device and Package page appears.35.Select the processor, for example TC27xC, and package, for example BGA292, for which you wantto make a pin configuration and click Finish.A pin configuration file with extension .pincfg is added to the existing project. Because the TASKIN
25、GC/C+ perspective is still active, Eclipse asks to open the TASKING Pin Mapper perspective.6.Optionally, enable the option Remember my decision and click Yes.The TASKING Pin Mapper perspective is opened.2.2.TASKING Pin Mapper PerspectiveThe TASKING Pin Mapper perspective contains several views. Each
26、 of the views are discussed in thefollowing sections.4Using the TASKING Pin Mapper for AURIX2.2.1.TASKING Pin Mapper Editor ViewThe TASKING Pin Mapper Editor view is the main area where you can make changes to your configuration.Port example5Getting Started with the TASKING Pin MapperPeripheral exam

For mappingparts which cannot be applied, the pin mapper issues a warning message.Import Pin ConfigurationYou can import saved

32、.2.Type the full path name of the configuration file (.pincfg), or use the Workspace button to selecta configuration from one of your project directories, or use the File System button to select one fromany directory.The imported configuration will be merged with the current configuration.If the cur
33、rent configuration already has settings for a pin or peripheral and the imported configuration hasother settings, pin conflicts errors or warnings may occur.Pin SelectionIn the left pane the port pins, peripherals and other pins are listed. Port pins can be logically grouped indifferent ways. Each o

Groups can be logically grouped into higher7Getting Started with the TASKING Pin Mapperlevel groups as long as the overall structure can be represented as a mathematical tree.The leafs of thetree are references to port pins, peripherals or peripheral sub-module
35、s.The tree structure of the grouping allows you to expand and collapse the view.In the type filter text edit field, you can add a port pin selection filter in order to reduce the numberof visible port pins.The filter is case insensitive. For example, type an to only show pins that have anin their na
