I've used in the application of lpc4330 hardware watchdog, the function of the configuration is timeout reset chip function, I met the question is: watchdog timeout after reset chip, I read the guard dog tags (WDTOF) to zero.Normally, the hardware reset that the watchdog causes will make this mark position 1, and then the software is zero.May I ask why?
