This mode may be used for all AES operating modes except CBC-MAC where AES_MR.LOD = 1 mode is recommended.
The end of the encryption/decryption is indicated by the end of DMA transfer associated to AES_ODATARx (see the figure below). Two DMA channels are required: one for writing message blocks to AES_IDATARx and one to obtain the result from AES_ODATARx.
