void AES_DMAConfig	(	AES_DMATransfer_TypeDef	AES_DMATransfer,
		FunctionalState	NewState
	)

Configures the AES DMA interface.

Parameters:

AES_DMATransfer,:	Specifies the AES DMA transfer. This parameter can be one of the following values: AES_DMATransfer_InOut: DMA requests enabled for input/Output transfer phase
NewState	Indicates the new state of the AES DMA interface. This parameter can be: ENABLE or DISABLE.

Return values:
