System designed to detect actuation of microprocessor operation monitoring internal system and method of zeroing microprocessor system equipped with a system detecting actuation of internal monitoring system

摘要

In a circuit for detection of internal microprocessor watchdog device execution comprising a microprocessor ( 6 ) with the internal watchdog device and with an input/output line ( 11 ) transmitting information about microprocessor reset, and a device for resetting the microprocessor system, to the input/output line ( 11 ) transmitting information about microprocessor ( 6 ) reset, a clock input CK is connected, which triggers the flip-flop ( 12 ), whose data input D and an inverted reset input /R are connected to the output of the device ( 19 ) for resetting the microprocessor system, and the inverted flip-flop ( 12 ) output /Q is connected to the input of the device ( 19 ^) for resetting the microprocessor system.
