Macro Definition Documentation

__HAL_WWDG_CLEAR_FLAG

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

Clears the WWDG's pending flags.

Parameters

<strong>HANDLE</strong>	WWDG handle
<strong>FLAG</strong>	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's interrupt pending bits bits to clear the selected interrupt pending bits.

Parameters

<strong>HANDLE</strong>	WWDG handle
<strong>INTERRUPT</strong>	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

#define __HAL_WWDG_ENABLE

(

__HANDLE__

)

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

Enables the WWDG peripheral.

Parameters

<strong>HANDLE</strong>

WWDG handle

Return values

None

__HAL_WWDG_ENABLE_IT

#define __HAL_WWDG_ENABLE_IT	(		__HANDLE__,
			__INTERRUPT__
	)		SET_BIT((__HANDLE__)->Instance->CFR, (__INTERRUPT__))

Enables the WWDG early wakeup interrupt.

Parameters

<strong>HANDLE</strong>	WWDG handle
<strong>INTERRUPT</strong>	specifies the interrupt to enable. This parameter can be one of the following values: WWDG_IT_EWI: Early wakeup interrupt

Note

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

Return values

None

__HAL_WWDG_GET_FLAG

#define __HAL_WWDG_GET_FLAG	(		__HANDLE__,
			__FLAG__
	)		(((__HANDLE__)->Instance->SR & (__FLAG__)) == (__FLAG__))

Check whether the specified WWDG flag is set or not.

Parameters

<strong>HANDLE</strong>	WWDG handle
<strong>FLAG</strong>	specifies the flag to check. This parameter can be one of the following values: WWDG_FLAG_EWIF: Early wakeup interrupt flag

Return values

The	new state of WWDG_FLAG (SET or RESET).

__HAL_WWDG_GET_IT

#define __HAL_WWDG_GET_IT	(		__HANDLE__,
			__INTERRUPT__
	)		__HAL_WWDG_GET_FLAG((__HANDLE__),(__INTERRUPT__))

Checks whether the selected WWDG interrupt has occurred or not.

Parameters

<strong>HANDLE</strong>	WWDG handle
<strong>INTERRUPT</strong>	specifies the it to check. This parameter can be one of the following values: WWDG_FLAG_EWIF: Early wakeup interrupt IT

Return values

The	new state of WWDG_FLAG (SET or RESET).

__HAL_WWDG_GET_IT_SOURCE

#define __HAL_WWDG_GET_IT_SOURCE	(		__HANDLE__,
			__INTERRUPT__
	)		(((__HANDLE__)->Instance->CFR & (__INTERRUPT__)) == (__INTERRUPT__))

Checks if the specified WWDG interrupt source is enabled or disabled.

Parameters

<strong>HANDLE</strong>	WWDG Handle.
<strong>INTERRUPT</strong>	specifies the WWDG interrupt source to check. This parameter can be one of the following values: WWDG_IT_EWI: Early Wakeup Interrupt

Return values

state

of INTERRUPT (TRUE or FALSE).
