◆ __HAL_DMA_CLEAR_FLAG

#define __HAL_DMA_CLEAR_FLAG (   __HANDLE__,
  __FLAG__ 
)    (DMA1->IFCR = (__FLAG__))

Clears the DMA Channel pending flags.

Parameters
__HANDLE__DMA handle
__FLAG__specifies the flag to clear. This parameter can be any combination of the following values:
  • DMA_FLAG_TCx: Transfer complete flag
  • DMA_FLAG_HTx: Half transfer complete flag
  • DMA_FLAG_TEx: Transfer error flag Where x can be 1_7 to select the DMA Channel flag.
Return values
None

◆ __HAL_DMA_GET_FLAG

#define __HAL_DMA_GET_FLAG (   __HANDLE__,
  __FLAG__ 
)    (DMA1->ISR & (__FLAG__))

Get the DMA Channel pending flags.

Parameters
__HANDLE__DMA handle
__FLAG__Get the specified flag. This parameter can be any combination of the following values:
  • DMA_FLAG_TCx: Transfer complete flag
  • DMA_FLAG_HTx: Half transfer complete flag
  • DMA_FLAG_TEx: Transfer error flag Where x can be 1_7 to select the DMA Channel flag.
Return values
Thestate of FLAG (SET or RESET).
