If TPS3813's WDT can be connect to Arm's GPIO?   I want to control time-out(250ms or 2.5s) by Arm's GPIO

    hi
    The delay can be calculated by the external cap value. Connecting to the ARM GPIO you would have fixed delay based on the IO state of the ARM IO pin. See section 7.7 of the datasheet.

    If external cap is used then the delay can be calculated by the following formula

    C(ext) ÷ 15.55 pF + 1) × 6.25 ms




    Thanks
