    Yuan,

    GPO2 can be configured as a watchdog failure output, GPIO1 can only be configured as a watchdog input trigger. You can find information on how to configure GPO2 as a watchdog failure output in the watchdog section of the TCAN4550-Q1 datasheet.

    Please let us know if you have any other questions.

    Regards,
