| Zusammenfassung: | A control circuit and method for detecting glitch signal of a bus, including: input ends, receiving data signal and clock signal of the bus; a counter, counting to calculate a time or number of low-level period of the clock signal; a comparator, comparing the time and a threshold to generate a comparison result; an error detector, generating an error flag when the comparison result indicating that there is level change in the low-level period of the clock signal. |
