ADAU1701 GPIO state 'hysteresis'

Hi, I am wondering if there is a way to have a GPIO pin stay high for a set amount of time when a logic level 1 is triggered?
I'm using a threshold detector to determine when an analog signal crosses a threshold. I want the gpio to stay high for 5 seconds even if it only sees a small blip above the threshold.

 

Any ideas?
