Zusammenfassung:A semiconductor die includes a feedback path coupled to the output pin, and an integrity monitor circuit (IMC). The output pin is communicatively coupled to the logic. The IMC is configured to receive a data value. The IMC is further configured to receive measured data value from the output pin routed through the feedback path, compare the data value and the measured data value, and, based on the comparison, determine whether an error has occurred.
