Appendix

Port Configuration SENT0SPCO output:

Port (that’s needs to be configured as SENT0SPCO) should be initialized as input DIO with level high.

The client call IoHwAb_SetFctPrphlHwTq0_Oper will reset the pin to output alternate mode for SENT0SPCO.

Introduction

Purpose

Module design document for Hand Wheel Torque 0 Measurement Function.

HwTq0Meas & High-Level Description

This module configures and processes the RSENT0 peripheral, which is connected to the handwheel torque 0 sensor. The module configures the peripheral, triggers transfers, and processes the received data.

This module also reads and provides the rack limiter EOT information which is stored in torque sensor 0 scratchpad.

Software Component Implementation

Sub-Module Functions

The sub-module functions are grouped based on similar functionality that needs to be executed in a given “State” of the system (refer States and Modes). For a given module, the MDD will identify the type and number of sub-modules required. The sub-module types are described below.

Init: HwTq0MeasInit1

Design Rationale

Magic numbers are used due to the large number of numeric values (for peripheral register configuration), it is more readable and easier to maintain without using embedded constants for these values. The values are shown in code comments, and line up exactly with the definitions given in the design module (a special spreadsheet was included in the design for this purpose).

See CM650A_HwTq0Meas_RSENTPeripheralCfg.xlsx in design module.

None

UNIT TEST CONSIDERATION

Overflow for the variables Rte_Pim_HwTq0MeasPrevRollgCntr, Rte_Pim_HwTq0MsgMissRxCnt, Rte_Pim_HwTq0ComStsErrCntr, Rte_Pim_HwTq0IntSnsrErrCntr are intentional as these are used as rolling counters.

Peer Review Summary Sheet

Synergy Project Name:

kzshz2: Intended Use: Identify which component is being reviewed. This should be the Module Short Name from Synergy Rationale: Required for traceability. It will help to ensure this form is not attaced to the the wrong change request. CM650A_HwTq0Meas_Impl

Revision / Baseline:

kzshz2: Intended Use: Identify which Synergy revision of this component is being reviewed Rationale: Required for traceability. It will help to ensure this form is not attaced to the the wrong change request. CM650A_HwTq0Meas_Impl_1.8.0

Change Owner:

kzshz2: Intended Use: Identify the developer who made the change(s) Rationale: A change request may have more than one resolver, this will help identify who made what change. Change owner identification may be required by indusrty standards. Avinash James

Work CR ID:

EA4#8586

kzshz2: Intended Use: Intended to identify at a high level to the reviewers which areas of the component have been changed. Rationale: This will be good information to know when ensuring appropriate reviews have been completed. Modified File Types:

kzshz2: Intended Use: Identify who where the reviewers, what they reviewed, and if the reviewed changes have been approved to release the code for testing. Comments here should be at a highlevel, the specific comments should be present on the specific review form sheet. Rationale: Since this Form will be attached to the Change Request it will confirm the approval and provides feedback in case of audits.

Comments:

Quality updates- Just imported the latest design project

General Guidelines: - The reviews shall be performed over the portions of the component that were modified as a result of the Change Request. - New components should include FDD Owner and Integrator as apart of the Group Review Board (Source Code, Integration Manual, and Davinci Files) - Enter any rework required into the comment field and select No. When the rework is complete, review again using this same review sheet and select Yes. Add date and additional comment stating that the rework is completed. - To review a component with multiple source code files use the "Add Source" button to create a Source code tab for each source file. - .h file should be reviewed with the source file as part of the source file.
