Macro Definition Documentation

◆ __HAL_WWDG_CLEAR_FLAG

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

Clear 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

Definition at line 233 of file stm32f7xx_hal_wwdg.h.

◆ __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

<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

Definition at line 213 of file stm32f7xx_hal_wwdg.h.

◆ __HAL_WWDG_ENABLE

#define __HAL_WWDG_ENABLE ( __HANDLE__ ) SET_BIT((__HANDLE__)->Instance->CR, WWDG_CR_WDGA)

Enable the WWDG peripheral.

Parameters

<strong>HANDLE</strong> WWDG handle

Return values

None

Definition at line 183 of file stm32f7xx_hal_wwdg.h.

◆ __HAL_WWDG_ENABLE_IT

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

Enable 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

Definition at line 194 of file stm32f7xx_hal_wwdg.h.

◆ __HAL_WWDG_GET_FLAG

#define __HAL_WWDG_GET_FLAG	(	__HANDLE__,

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).

Definition at line 223 of file stm32f7xx_hal_wwdg.h.

◆ __HAL_WWDG_GET_IT

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

Check whether the selected WWDG interrupt has occurred or not.

Parameters

<strong>HANDLE</strong>	WWDG handle

Return values

The	new state of WWDG_FLAG (SET or RESET).

Definition at line 204 of file stm32f7xx_hal_wwdg.h.

◆ __HAL_WWDG_GET_IT_SOURCE

#define __HAL_WWDG_GET_IT_SOURCE	(	__HANDLE__,
		__INTERRUPT__
	)

Value:

(((__HANDLE__)->Instance->CFR\

& (__INTERRUPT__)) == (__INTERRUPT__))

Check whether the specified WWDG interrupt source is enabled or not.

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).
