HASH control register
| INIT | Initialize message digest calculation |
| DMAE | DMA enable 0 (B_0x0): DMA transfers disabled 1 (B_0x1): DMA transfers enabled. |
| DATATYPE | Data type selection 0 (B_0x0): 32-bit data. 1 (B_0x1): 16-bit data or half-word. 2 (B_0x2): 8-bit data or bytes. 3 (B_0x3): bit data or bit string. |
| MODE | Mode selection 0 (B_0x0): Hash mode selected 1 (B_0x1): HMAC mode selected. |
| NBW | Number of words already pushed |
| DINNE | DIN not empty |
| MDMAT | Multiple DMA transfers 0 (B_0x0): DCAL is automatically set at the end of a DMA transfer. 1 (B_0x1): DCAL is not automatically set at the end of a DMA transfer. |
| LKEY | Long key selection 0 (B_0x0): HMAC key is shorter or equal to the block size (short key). 1 (B_0x1): HMAC key is longer than the block size (long key). |
| ALGO | Algorithm selection 0 (B_0x0): SHA-1 2 (B_0x2): SHA2-224 3 (B_0x3): SHA2-256 12 (B_0xC): SHA2-384 13 (B_0xD): SHA2-512/224 14 (B_0xE): SHA2-512/256 15 (B_0xF): SHA2-512 |
