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

Clear 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 DMA_FLAG_GLx: Global interrupt flag Where x can be 1_7 to select the DMA Channel flag.

Return values:

None
