AVR32 & Queue Management

HI, is there any known reason, why the AVR32 can call the following exception: exception.s82: ORG 0x034         // Data Address (Read). _handle_Data_Address_Read:         rjmp $ I think it has something to do with queue handling. The vApplicationIdleHook() is not blocked or suspended. Best regards Karsten
