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.
void CRYP_DMACmd | ( | uint8_t | CRYP_DMAReq, |
FunctionalState | NewState | ||

Enables or disables the CRYP DMA interface.
CRYP_DMAReq | specifies the CRYP DMA transfer request to be enabled or disabled. This parameter can be any combination of the following values:
|
NewState | new state of the selected CRYP DMA transfer request. This parameter can be: ENABLE or DISABLE. |
