Macro Definition Documentation

__HAL_DMA_CLEAR_FLAG

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

Clear the DMA Channel pending flags.

Parameters

<strong>HANDLE</strong>	DMA handle
<strong>FLAG</strong>	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

__HAL_DMA_GET_FLAG

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

Get the DMA Channel pending flags.

Parameters

<strong>HANDLE</strong>	DMA handle
<strong>FLAG</strong>	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 DMA_FLAG_GLx: Global interrupt flag Where x can be 1_7 to select the DMA Channel flag.

Return values

The	state of FLAG (SET or RESET).
