Abstract

A software-initiated system reset 10 is generated in response to invalid interrupts generated within a system which comprises control means for maintaining system control, and at least one device external to and under the control of the control means. An assessment as to the validity of an interrupt generated within the system is made, 14, whereupon the system reset is actuated, 15-19, 21-24, in response to an invalid interrupt and a software generated system reset signal is provided for the external device. Moreover, the actuation of the system reset causes the external device to be reset together with the control means. The invention alleviates problems, caused by inappropriate accessing of normally-unused interrupt vectors, due e.g. to noise spikes, RF transmissions and hardware or software failures. <IMAGE>
