LL_WWDG_SetCounter() function
Set the Watchdog counter value to provided value (7-bits T[6:0])
Syntax
Return value
None
Notes
When writing to the WWDG_CR register, always write 1 in the MSB b6 to avoid generating an immediate reset This counter is decremented every (4096 x 2expWDGTB) PCLK cycles A reset is produced when it rolls over from 0x40 to 0x3F (bit T6 becomes cleared) Setting the counter lower then 0x40 causes an immediate reset (if WWDG enabled)

Indicates if the WWDG Early Wakeup Interrupt Flag is set or not.
Clear WWDG Early Wakeup Interrupt Flag (EWIF)
Enable the Early Wakeup Interrupt.
Check if Early Wakeup Interrupt is enabled
Checks if Window Watchdog is enabled
