/*
Testet coreinterrupt_e
Die Funktion generate_coreinterrupt wird danach getestet, ob ein Interrupt tatsächlich generiert
und ausgeführt wird.
Danach werden die Interrupts maskiert und is_coreinterrupt und clear_coreinterrupt
werden getestet.
Die Funktion ispending liefert 1, wenn ein generierter Interrupt auf Ausführung
wartet, d.h. die Priorität ist nicht ausreichend oder alle Interrupts wurden maskiert.
Die Funktion clearpending löscht das Pending-Flag des Interrupts, so dass ispending 0 liefert und der Interrupt
daher nicht mehr ausgeführt wird.
