Function Documentation

void WWDG_DeInit

(

void

)

Deinitializes the WWDG peripheral registers to their default reset values.

Parameters

None

Return values

None

Here is the call graph for this function:

void WWDG_EnableIT

(

void

)

Enables the WWDG Early Wakeup interrupt(EWI).

Note

Once enabled this interrupt cannot be disabled except by a system reset.

Parameters

None

Return values

None

void WWDG_SetCounter

(

uint8_t

Counter

)

Sets the WWDG counter value.

Parameters

Counter

specifies the watchdog counter value. This parameter must be a number between 0x40 and 0x7F (to prevent generating an immediate reset)

Return values

None

void WWDG_SetPrescaler

(

uint32_t

WWDG_Prescaler

)

Sets the WWDG Prescaler.

Parameters

WWDG_Prescaler

specifies the WWDG Prescaler. This parameter can be one of the following values: WWDG_Prescaler_1: WWDG counter clock = (PCLK1/4096)/1 WWDG_Prescaler_2: WWDG counter clock = (PCLK1/4096)/2 WWDG_Prescaler_4: WWDG counter clock = (PCLK1/4096)/4 WWDG_Prescaler_8: WWDG counter clock = (PCLK1/4096)/8

Return values

None

void WWDG_SetWindowValue

(

uint8_t

WindowValue

)

Sets the WWDG window value.

Parameters

WindowValue

specifies the window value to be compared to the downcounter. This parameter value must be lower than 0x80.

Return values

None
