DigPhsReasDiag_MDD

Module --

High-Level Description

This module compares the commanded duty cycle to each phase with the feedback from the NHET module. The values are compared, compensated with a previously defined fixed value, filtered, and compared against a valid threshold.

Variable Data Dictionary

For details on module input / output variable, refer to the Data Dictionary for the application. Input / output variable names are listed here for reference.

Module Internal Variables

This section identifies the name, range and resolutions for module specific data created by this module. If there are no range restrictions on the variable, the term “FULL” is placed into the table for legal range.

User defined typedef definition/declaration

This section documents any user types uniquely used for the module.

Constant Data Dictionary

Calibration Constants

This section lists the calibrations used by the module. For details on calibration constants, refer to the Data Dictionary for the application.

The time constant for the filter is analyzed in the following filter analysis workbook:

Program(fixed) Constants

Embedded Constants

All embedded constants whose values are provided in Eng units will be evaluated to the equivalent counts by using the FPM_InitFixedPoint_m() macro within the #define statement.

Local

Global

This section lists the global constants used by the module. For details on global constants, refer to the Data Dictionary for the application.

Module specific Lookup Tables Constants

(This is for lookup tables (arrays) with fixed values, same name as other tables)

Software Module Implementation

Runtime Environment (RTE) Initial Values

This section lists the initial values of data written by this module but controlled by the RTE. After RTE initialization, the data in this table will contain these values.

Initialization Functions

DigPhsReasDiag_Init

Periodic Functions

Per: DigPhsReasDiag_ Per1

Design Rationale

The ParamBits_Cnt_T_u08 variable used in this function, which is passed when calling NxtrDiagMgr_SetNTCStatus, is set according to the following table (derived from the DTC Outline Structure document):
