PM8916 WatchDog timeout


My customer 410C Board is setted to USB boot mode, when we flash image in first time . A reset signal is traggered by PM8916 in about 30 seconds. So download is terminated. According to PM8916 datasheet, the default value of PM8916 watchdog overtime is 31 seconds. How to turn off the watchdog when flashing a new board? How to disable watchdog of PM8916?
