Function name
__STATIC_INLINE void LL_WWDG_SetWindow
(WWDG_TypeDef * WWDGx, uint32_t Window)
Function description
Set the Watchdog Window value to be compared to the
downcounter (7-bits W[6:0]).
Parameters
WWDGx: WWDG Instance
Window: 0x00..0x7F (7 bit Window value)
Return values
None:
Notes
This window value defines when write in the WWDG_CR
register to program Watchdog counter is allowed. Watchdog
counter value update must occur only when the counter value
is lower than the Watchdog window register value. Otherwise,
a MCU reset is generated if the 7-bit Watchdog counter value
(in the control register) is refreshed before the downcounter
has reached the watchdog window register value. Physically
is possible to set the Window lower then 0x40 but it is not
recommended. To generate an immediate reset, it is possible
to set the Counter lower than 0x40.
