ABSTRACT:
A device for monitoring a processor is described. A watchdog simultaneously monitors the system clock, the software base functions and performs a check of the tests of the system components of the processor. If an error is detected, the watchdog communicates this to the processor, an error counter is incremented and at least one device that is connected to the processor is blocked. If the error counter attains a predetermined value, the block is continued until the device of the present invention is deactivated. If an additional error is detected during a blocking time, the blocking time is extended.
