Abstract
The invention relates to a microprocessor circuit arrangement having a watchdog circuit, which monitors the proper program flow for the processor and which must be triggered in specific time intervals by the microprocessor, since otherwise it will reset (reset function) the microprocessor to the program start or the like. For reasons of simplification, it is proposed that when the microprocessor (2) recognizes that a malfunction has occurred, it spuriously triggers the watchdog circuit (5) in a selective manner to release a reset function coming from the watchdog circuit (5).
