  • Publication number: 20250004978
    Abstract: A device includes a signal-edge detector, an anomaly detector and a reset-interrupt generator. The signal-edge detector outputs a timing-start signal when detecting that a logic level of an SDA signal from an SDA line of an I2C bus changes from logical high to logical low, and outputs a timing-reset signal when detecting that the logic level changes from logical low to logical high. Upon receiving the timing-start signal, the anomaly detector starts to time a timing duration, and outputs an error signal when the timing duration reaches a preset time duration. Upon receiving the timing-reset signal, the anomaly detector resets the timing duration to zero. In response to receipt of the error signal, the reset-interrupt generator outputs an interrupt signal to a processor for removing an abnormal state, or outputs a pin-reset signal to an optical module to reset a pin connected to the SDA line.
