FAQ
How long can a user clear a time-out event flag before the Watchdog Timer (WDT) generates a system reset signal when the Watchdog Timer (WDT) counter overflows and triggers a time-out event? Issue Date：2015-07-17
Depending on the NuMicro® series, before the WDT generates a system reset signal, the Watchdog Timer (WDT) has a different delay period (TRSTD), as listed below:
