Detailed Description

HASH's DMA interface Configuration function.

 ===============================================================================
               ##### HASH's DMA interface Configuration function #####
 ===============================================================================  

 [..] This section provides functions allowing to configure the DMA interface for 
      HASH/ HMAC data input transfer.
   
 [..] When the DMA mode is enabled (using the HASH_DMACmd() function), data can be 
      sent to the IN FIFO using the DMA peripheral.

Function Documentation

void HASH_AutoStartDigest ( FunctionalState NewState )

Enables or disables auto-start message padding and calculation of the final message digest at the end of DMA transfer.

Parameters

NewState new state of the selected HASH DMA transfer request. This parameter can be: ENABLE or DISABLE.

Return values

None

void HASH_DMACmd ( FunctionalState NewState )

Enables or disables the HASH DMA interface.

Note: The DMA is disabled by hardware after the end of transfer.
