Yes, you should be able to connect the output of your external watchdog timer to the POR pin.
However, from the TPS3850H01DRCT datasheet, I see that the recommendation is to connect it to a NMI pin, so I suggest doing it this way instead.

Hi @EdwinHz ,
Based on your response, I understand that TPS3850H01DRCT (WDO) can be connected to the POR pin which is also a non-maskable interrupt pin (NMI) of MIMXRT1024CAG4B. Is my understanding correct?
