Datasheet says following in P4 “Timing Rules of Window-Watchdog”.
After the reset of the supervisor is released, the lower boundary of the first WDI window is
disabled. However, after the first WDI pulse low-to-high transition is detected, the lower
boundary function is enabled.
Please advise the behavior of Watchdog, in case of No WDI pulse low-to-high transition is detected after reset is released.
Does watchdog wait WDI pulse forever and no reset to MCU?
