(WWDG_TypeDef * WWDGx, uint32_t Prescaler)
Function description
Set the time base of the prescaler (WDGTB).
Parameters
WWDGx: WWDG Instance
Prescaler: This parameter can be one of the following
values:
LL_WWDG_PRESCALER_1
LL_WWDG_PRESCALER_2
LL_WWDG_PRESCALER_4
LL_WWDG_PRESCALER_8
Return values
None:
Notes
Prescaler is used to apply ratio on PCLK clock, so that
Watchdog counter is decremented every (4096 x
2expWDGTB) PCLK cycles
