Abstract

Es wird ein Verfahren zum Betreiben einer Schaltungsanordnung vorgeschlagen, die einen Mikrocontroller (10) und ein EEPROM (11) enthält. Im EEPROM (11) wird ein erster Speicherbereich (29) mit zumindest einem Datensatzspeicher (DA1, DA2, DA3) und zumindest ein zweiter Speicherbereich (30) mit zumindest einem Datensatzspeicher (DB1, DB2, DB3) vorgesehen. Ein in einem dritten Speicherbereich (31) angeordneter, Pointer (P1, P2, P3) verweist auf den jeweils gültigen Speicherbereich (29, 30). Der Mikrocontroller (10) speichert in einem Schritt (53) einen Datensatz in den ungültigen Speicherbereich (29, 30) und ändert in einem nachfolgenden Schritt (54) den Pointer (P1, P2, P3) derart, dass der ungültige zum gültigen Speicherbereich (29, 30) wird. Die beiden Schritte (53, 54) werden zyklisch wiederholt. Bei einem auftretenden Fehler wahrend eines Speichervorgangs steht in dem als gültig gekennzeichneten Speicherbereich (29, 30) stets ein korrekter Datensatz zur Verfügung.
