◆ __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

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

Parameters
__HANDLE__WWDG handle
__INTERRUPT__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
