Introduction

The PORT Driver Component comprises of two sections that is,
embedded software and the configuration tool to achieve scalability and
configurability. The PORT Driver Component Code Generation Tool is a
command line tool that accepts ECU configuration description files as
input and generates C Source and C Header files. The configuration
description is an ARXML file that contains information about the
configuration for PORT pins. The tool generates Port_Cfg.h, Port_Cbk.h
and Port_PBcfg.c files.

The Figure in the following page depicts the PORT Driver as part of layered

4.1.
General

Following information will aid the user to use the PORT Driver Component
software efficiently:

•
The PORT Driver Component does not enable or disable the ECU or
Microcontroller power supply. The upper layer should handle this
operation.
•
Start-up code is not implemented by the PORT Driver Component.
•
PORT Driver Component does not implement any callback
notification functions.
•
PORT Driver Component does not implement any scheduled functions.
•
The PORT Driver Component is restricted to Post Build only.
•
The authorization of the user for calling the software triggering of a
hardware reset is not checked in the PORT Driver Component. This will
be the responsibility of the upper layer.
•
The PORT Driver Component supports setting of Analog and Digital
Noise Elimination. To figure out the different port filter arrangements the
device User Manual should be taken as reference. If no configuration of a
certain port filter is done within this Port Module, the device specific
default settings will take effect on this filter.
•
The value of unused pins are set to defined state. i.e Mode = DIO,
Direction = Input, Pin Level Value = LOW
•
All development errors will be reported to DET by using the
API Det_ReportError provided by DET.
•
All production errors will be reported to DEM by using the
API Dem_ReportErrorStatus provided by DEM.
•
The PORT Driver does not have the API support to read the status of
Port pins or Port registers. Hence PORT Driver will not support ‘Read
back’ feature.
•
The file Interrupt_VectorTable.c provided is just a Demo and not all
interrupts will be mapped in this file. So the user has to update the
Interrupt_VectorTable.c as per his configuration.
•
Port_SetToDioMode and Port_SetPinDefaultMode Api shall not change
or affect the level of the requested pin.
•
The access to HW registers is possible only using AUTOSAR standard
and vendor specific API functions described in this document (Chapter
10).
•
The output level of each pin can be inverted by configuring the required
value (true/false) through the configuration parameter
PortOutputLevelInversion.
•
The functions/variables with "STATIC" as pilot tag, provides an
indication to the compiler that the function/variable following this tag is a
static type. So the scope of static functions/variables is restricted to the
file where they are declared. User should take care of the tag name with
respect to compiler used.
•
During changing direction to OUTPUT for a particular pin, the pin level
value (PSR register) is also set to the default configured value in order
to avoid an undefined output level of the pin. This needs to be
considered for any application software controlling the pin.
•
The default value for the parameter 'PortLoopTimeout' is ‘5’. The user shall
configure the parameter 'PortLoopTimeout' to standard default value ‘5’ to
avoid unwanted reporting of DEM due to protected register write failure.
The maximum value of this parameter 'PortLoopTimeout' is '255'.

4.2.
Preconditions

Following preconditions have to be adhered by the user, for proper
functioning of the PORT Driver Component:

•
The Port_PBcfg.c, Port_Cfg.h and Port_Cbk.h files generated by the
PORT Driver Component Code Generation Tool must be compiled and
linked along with PORT Driver Component source files.
•
The application has to be rebuilt, if there is any change in the Port_Cfg.h
file generated by the PORT Driver Component Generation Tool.
•
File Port_PBcfg.c generated for single configuration set or multiple
configuration sets using PORT Driver Component Code Generation Tool
should be compiled and linked independently.
•
Symbolic names for all Port Pins are generated in Port_Cfg.h file which
can be used as parameters for passing to PORT Driver Component APIs.
•
The PORT Driver Component needs to be initialized for all Port Pins
before doing any operation on Port Pins. The Port_Init () API shall also be
called after a reset in order to reconfigure the Port Pins of the
microcontroller. If PORT Driver Component is not initialized properly, the
behavior of Port Pins may be undetermined.
•
The user should ensure that PORT Driver Component API requests are
invoked with correct input arguments.
•
The other modules depending on PORT Driver Component should ensure
that the PORT Driver Component initialization is successful before doing
any operation on Port Pins.
•
Input parameters are validated only when the static configuration
parameter PORT_DEV_ERROR_DETECT is enabled. Application should
ensure that the right parameters are passed while invoking the APIs when
PORT_DEV_ERROR_DETECT is disabled.
•
Values for production code Event Id’s should be assigned externally by the
configuration of the DEM.
•
A mismatch in the version numbers of header and the source files will
result in a compilation error. User should ensure that the correct versions
of the header and the source files are used.
•
The PORT Driver Component APIs, except Port_GetVersionInfo API,
which are intended to operate on Port Pins shall be called only after PORT
Driver Component is initialized by invoking Port_Init() API. Otherwise Port
Pin functions will exhibit undefined behavior.
•
All Port Pins and their functions should be configured by the Port
configuration tool. It is the User/Integrator responsibility to ensure that the
same Port/Port Pin is not being accessed/configured in parallel by different
entities in the same system.
•
User  have  the  responsibility  to  enable  or  disable  the  critical  protection
using
the
parameter
PortCriticalSectionProtection.  By
enabling
parameter  PortCriticalSectionProtection,  Microcontroller  HW  registers
which suffer from concurrent access by multiple tasks, are protected.
•
The  same  alternative  function  should  not  be  assigned  to  two  different
pins at same time.

table.

4.4.
Data Consistency

To support the re-entrance and interrupt services, the AUTOSAR PORT
component will ensure the data consistency while accessing its own RAM
storage or hardware registers. The PORT component will use
SchM_Enter_Port_<Exclusive Area> and SchM_Exit_Port_<Exclusive Area>
functions. The SchM_Enter_Port_<Exclusive Area> function is called before
the data needs to be protected and SchM_Exit_Port_<Exclusive
Area>function is called after the data is accessed.

The following exclusive areas along with scheduler services are used to
provide data integrity for shared resources:
•
PORT_SET_PIN_MODE_PROTECTION
•
PORT_SET_PIN_DIR_PROTECTION
•
PORT_SET_TO_DIO_ALT_PROTECTION
•
PORT_INIT_CONFIG_PROTECTION
•
PORT_REFRESHPORT_INTERNAL_PROTECTION
•
PORT_SET_PIN_DEFAULT_MODE_PROTECTION
•
PORT_SET_PIN_DEFAULT_DIR_PROTECTION

The functions SchM_Enter_Port_<Exclusive Area> and
SchM_Exit_Port_<Exclusive Area> can be disabled through the
configuration parameter ‘PortCriticalSectionProtection’.

Module Version Information

Port Initialization

This sub module provides the Port initialization functionality by providing the
Port_Init() API. This API should be invoked before the usage of any other APIs
of PORT Driver Component. Port Initialization includes initializing Port Pin
mode, Port Pin direction, Port Pin Level value, Port Pin driven value (Normal /
Open Drain), Activation of internal pull-ups and Port Filter configuration.

Port Direction Refreshing

This sub module provides the Port Direction Refreshing functionality by
providing the Port_RefreshPortDirection() API. In this functionality the PORT
Driver Component refreshes the direction of all configured Port Pins except
those Port Pins that are configured as ‘Port Pin Direction Changeable during
runtime’.

In this functionality only Direction of Port Pins is refreshed.

Port Pin Direction Switching

This sub module provides the Port Direction switching functionality at run time
by providing the the Port_SetPinDirection() API. In this functionality the
PORT driver Component allows the user to change the direction of Port Pins
during runtime.

This sub module provides the Port Direction switching functionality at run time
by providing the Port_SetPinDefaultDirection() API. In this functionality the
PORT driver Component allows the user at runtime to change the direction of
Port Pins to default direction set by the configuration at the time of Port_Init().

Port Pin Mode changing

This sub module provides the Port Mode change functionality at run time by
providing the Port_SetPinMode() API. In this functionality the PORT driver
Component allows the user to change the mode of Port Pins during runtime.

This sub module provides the Port Mode change functionality at run time by
providing the Port_SetToDioMode() API. In this functionality the PORT
driver Component allows the user to change the mode of Port Pin to DIO
mode during runtime.

This sub module provides the Port Mode change functionality at run time by
providing the Port_SetToAlternateMode() API. In this functionality the PORT
driver Component allows the user to change the mode of Port Pin to alternate
mode during runtime.

This sub module provides the Port Mode change functionality at run time by
providing the Port_SetPinDefaultMode() API. In this functionality the PORT
driver Component allows the user at runtime to change the mode of Port Pin
to default mode set by the configuration at the time of Port_Init().

Module Version Information

The Api Port_GetVersionInfo is responsible for reading the version information
of the PORT Driver Information. The verison information includes Module ID,
Vendor ID, and Version number of the PORT Driver software.

Remark  GNU Make utility version 3.81 or above must be installed and available in the
path  as  defined  by  the  environment  user  variable  “GNUMAKE”  to  complete
the build process using the delivered sample files.

Open a Command window and change the current working directory to “make”
directory present as mentioned in below path:

“X1X\P1x\common_family\make\<Compiler>”

Now execute the batch file SampleApp.bat with following parameters:

SampleApp.bat Port 4.0.3 <Device_name>

•
After this, the tool output files will be  generated with the configuration
as
mentioned
in
App_PORT_P1M_701318_Sample.arxml  file
available in the path:

“X1X\P1x\modules\port\sample_application\<SubVariant>\<AUTOSAR_ve
rsion>\config\App_PORT_P1M_701318_Sample.arxml”

App_PORT_P1M_Sample.out will be available in the output folder:
(“X1X\P1x\modules\port\sample_application\<SubVariant>
\obj\<Compiler>”)

•
The executable can be loaded into the debugger and the sample application
can be executed.

•
The initialization function initializes all ports and port pins with the
configuration set pointed by ConfigPtr by invoking internal API
Port_InitConfig(). This function should be called first in order to initialize the
port for use otherwise no operation can occur on the MCU ports and port
pins. This function is also called after reset, in order to reconfigure the ports
and port pins of the MCU.

•
Port_SetPinMode: This API will change the pin mode to the requested
mode.

•
Port_SetToDioMode: This API will set the mode of a pin to DIO mode.

54

P1M Specific Information
Chapter 13
•
Port_SetToAlternateMode: This API will set the mode of a port pin to
Alternate mode.

•
Port_SetPinDirection: This API will change the direction of the pin to the
requested direction.

•
Port_RefreshPortDirection: This API will refresh all the port pins to the
configured value except the pins that are configured as pin direction
changeable during runtime.

Note: The <Device_name> indicates the device to be compiled, which can be
701304 or   701305 or 701310 or 701311 or 701312 or 701313 or

hardware with the help of Green Hills debugger.

•
If any configuration changes (only post-build) are made to the ECU
Configuration Description files

“X1X\P1x\modules\port\sample_application\<SubVariant>
\<AUTOSAR_version>\config\App_PORT_P1M_701318_Sample.arxml”

•
The database alone can be generated by using the following commands.
make –f App_PORT_P1M_Sample.mak generate_port_config
make –f App_PORT_P1M_Sample.mak App_PORT_P1M_Sample.s37
