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.
| Data | Value |
|---|---|
| ATermActive_Cnt_lgc | TRUE |
| CTermActive_Cnt_lgc | FALSE |
| EngRPM_Cnt_u16 | 0 |
| EngONSrlComSvcDft_Cnt_lgc | FALSE |
| VehSpd_Kph_f32 | 0 |
| VehSpdValid_Cnt_lgc | FALSE |
| OperRampRate_XpmS_f32 | 0 |
| OperRampValue_Uls_f21 | 0 |
Initialization Functions
Init: _Init1
Design Rationale
Module Outputs

Periodic Functions
Per: _Per1
Design Rationale
There are a set of inputs that are read in but not used. This is because these inputs are likely to be used in the final design. The current implementation does not meet final design requirements.
