A system reset will be performed if the watchdog is in Window mode and is triggered less than t
period (or in the first half of the watchdog period).
The nominal watchdog period is programmed via the NWP control bits in the WD_and_Status register (see
Window mode only.
The watchdog will be reset if it is in window mode and is triggered at least t
watchdog period (or in the second half of the watchdog period). A system reset will be performed if the watchdog is triggered more than
