UCD90120A: UCD90120A - GPO Configure settings

Part Number: UCD90120A

Hi TI,

I have a question about GPO configure settings. It's a unexpected behavior since I added a input path of logic gate.

The behavier of GPI will be changed to continuous pulse. This is not a correct  behavior we expected.

I'm so confused about why configure settings cause this abnormal behavior. I think GPI is just  a input signal, why UCD90120A's configure settings can change the spurce's behavior ?

GPI12 is a active high signal for thermal alert from systm. Our purpose is UCD90120A to  turn-off  2.5V power rail if thermal alert is triggered.

Could you help to check which incorect settings cause this behavior ? I also attach related waveform and settings for comparing.
