Watchdog Interface (WdgIf)

Map the service Wdg If_ Set Mode to the serv ice Wdg_ Set Mode of the corresponding Watchdog Driver.

Map the service Wdg If_ Set Trigger Condition to the service Wdg_ Set Trigger Condition of the corresponding Wa tchdog Driver.

Returns the version information.

[SWS_WdgIf_00013] Upstream requirements: SRS_BSW_00304 ⌈The data type for the watchdog device index shall be uint8. DeviceIndex shall provide a zero-based consecutive index.⌋

[SWS_WdgIf_00017] Upstream requirements: SRS_Wdg_12165, SRS_Wdg_12167, SRS_MemHwAb_14019 ⌈The Watchdog Interface shall map the APIs specified in this chapter to the API of the driver⌋

[SWS_WdgIf_00018] Upstream requirements: SRS_MemHwAb_14020 ⌈The Watchdog Interface shall use the parameter DeviceIndex for selection of watchdog drivers. If only one watchdog driver is configured, the parameter Devi- ceIndex shall be ignored.⌋

[SWS_WdgIf_00019] Upstream requirements: SRS_MemHwAb_14021 ⌈If only one watchdog driver is configured, the Watchdog Interface shall cause no runtime overhead when mapping the Watchdog Interface API to the API of the corre- sponding Watchdog Driver.⌋ Implementation hint: This could be done by using macros as for example #define WdgIf_SetMode(DeviceIndex, WdgMode) \ Wdg_SetMode(WdgMode)

[SWS_WdgIf_00020] Upstream requirements: SRS_MemHwAb_14021 ⌈If more than one watchdog driver is configured, the Watchdog Interface shall use efficient mechanisms to map the API calls to the appropriate watchdog driver.⌋ Implementation hint: One solution is to use tables of pointers to functions where the parameter DeviceIndex is used as array index, for example #define WdgIf_SetMode(DeviceIndex, WdgMode) \ SetModeFctPtr[DeviceIndex](WdgMode) Note: The service IDs are related to the service IDs of the watchdog driver specification [7]. For that reason, they may not start with 0.

If more than one watchdog driver is configured and the develop m ent error detection is enabled for this module, the parameter DeviceIndex shall be checked for being an existing device within the module’s services . Detected errors shall be reported to the Default Error Tracer (DET) w ith the error code WDGIF_E_PARAM_DEVICE and the called service shall not be executed.
