Each module can be provided with three handlers which are called during the respective phases as described below:
| Module Handler | Purpose | API for Registering the Handler | Execution context |
|---|---|---|---|
| Init | Called during the init of the core to configure the module, register for events or add scheduler tasks. This can be used to load the configuration data into the module if required. | XPfw_CoreSetCfgHandler(const XPfw_Module_t *ModPtr, XPfwModCfgInitHandler_tCfgHandler); | StartUp |
| Event Handler | Called when an event occurs (module should have registered for this event, preferably during the init phase | XPfw_CoreSetEventHandler(const XPfw_Module_t *ModPtr, XPfwModEventHandler_t EventHandler); | Interrupt |
| IPI Handler | Called when an IPI message with respective module-id arrives | XPfw_CoreSetIpiHandler(const XPfw_Module_t *ModPtr, XPfwModIpiHandler_t IpiHandler, u16 IpiId); | Interrupt |
