Detailed Description

CRYP's DMA interface Configuration function.

 ===============================================================================
             ##### CRYP's DMA interface Configuration function #####
 ===============================================================================  
 [..] This section provides functions allowing to configure the DMA interface for 
      CRYP data input and output transfer.
   
 [..] When the DMA mode is enabled (using the CRYP_DMACmd() function), data can be 
      transferred:
   (+) From memory to the CRYP IN FIFO using the DMA peripheral by enabling 
       the CRYP_DMAReq_DataIN request.
   (+) From the CRYP OUT FIFO to the memory using the DMA peripheral by enabling 
       the CRYP_DMAReq_DataOUT request.

Function Documentation

void CRYP_DMACmd	(	uint8_t	CRYP_DMAReq,
		FunctionalState	NewState
	)

Enables or disables the CRYP DMA interface.

Parameters

CRYP_DMAReq	specifies the CRYP DMA transfer request to be enabled or disabled. This parameter can be any combination of the following values: CRYP_DMAReq_DataOUT: DMA for outgoing(Tx) data transfer CRYP_DMAReq_DataIN: DMA for incoming(Rx) data transfer
NewState	new state of the selected CRYP DMA transfer request. This parameter can be: ENABLE or DISABLE.

Return values

None
