__HAL_WWDG_CLEAR_FLAG

#define __HAL_WWDG_CLEAR_FLAG	(		__HANDLE__,
			__FLAG__
	)		((__HANDLE__)->Instance->SR = ~(__FLAG__))

Clear the WWDG's pending flags.

Parameters

__HANDLE__	WWDG handle
__FLAG__	specifies the flag to clear. This parameter can be one of the following values: WWDG_FLAG_EWIF: Early wakeup interrupt flag

Return values

None

__HAL_WWDG_CLEAR_IT

#define __HAL_WWDG_CLEAR_IT	(		__HANDLE__,
			__INTERRUPT__
	)		__HAL_WWDG_CLEAR_FLAG((__HANDLE__), (__INTERRUPT__))

Clear the WWDG interrupt pending bits. bits to clear the selected interrupt pending bits.

Parameters

__HANDLE__	WWDG handle
__INTERRUPT__	specifies the interrupt pending bit to clear. This parameter can be one of the following values: WWDG_FLAG_EWIF: Early wakeup interrupt flag

__HAL_WWDG_ENABLE

(

__HANDLE__

)

SET_BIT((__HANDLE__)->Instance->CR, WWDG_CR_WDGA)

Enable the WWDG peripheral.

Parameters

__HANDLE__

WWDG handle

Return values

None

__HAL_WWDG_ENABLE_IT

#define __HAL_WWDG_ENABLE_IT	(		__HANDLE__,
			__INTERRUPT__
