WDT_RESET_N,OVERTEMP_N,TEMP_ALERT_N
Are these three signals triggered by falling edge or low level？
Because these three signals connect to a i/o expander, the expander doesn’t have the ability to catch the falling edge.
Please check pinmux first. All three pins are level triggered. WDT_RESET_N and TEMP_ALERT_N are unconnected on devkit.
