CIPHER_ENCRYPT=DECRYPT, HASH_OUTPUT=INPUT
DCP work packet 1 status register
| INTERRUPT | Reflects whether the channel must issue an interrupt upon the completion of the packet. |
| DECR_SEMAPHORE | Reflects whether the channel’s semaphore must be decremented at the end of the current operation |
| CHAIN | Reflects whether the next command pointer register must be loaded into the channel’s current descriptor pointer |
| CHAIN_CONTIGUOUS | Reflects whether the next packet’s address is located following this packet’s payload. |
| ENABLE_MEMCOPY | Reflects whether the selected memory-copy (memcopy) function should be enabled for this operation. |
| ENABLE_CIPHER | Reflects whether the selected cipher function must be enabled for this operation. |
| ENABLE_HASH | Reflects whether the selected hashing function must be enabled for this operation. |
| ENABLE_BLIT | Reflects whether the DCP must perform a blit operation |
| CIPHER_ENCRYPT | When the cipher block is enabled, this bit indicates whether the operation is encryption or decryption 0 (DECRYPT): DECRYPT 1 (ENCRYPT): ENCRYPT |
| CIPHER_INIT | Reflects whether the cipher block must load the initialization vector from the payload for this operation |
| OTP_KEY | Reflects whether a hardware-based key must be used |
| PAYLOAD_KEY | When set, it indicates the payload contains the key |
| HASH_INIT | Reflects whether the current hashing block is the initial block in the hashing operation, so the hash registers must be initialized before the operation |
| HASH_TERM | Reflects whether the current hashing block is the final block in the hashing operation, so the hash padding must be applied by the hardware |
| CHECK_HASH | Reflects whether the calculated hash value must be compared to the hash provided in the payload. |
| HASH_OUTPUT | When the hashing is enabled, this bit controls whether the input or output data is hashed. 0 (INPUT): INPUT 1 (OUTPUT): OUTPUT |
| CONSTANT_FILL | When this bit is set (MEMCOPY and BLIT modes only), the DCP simply fills the destination buffer with the value found in the source address field |
| TEST_SEMA_IRQ | This bit is used to test the channel semaphore transition to 0. FOR TEST USE ONLY! |
| KEY_BYTESWAP | Reflects whether the DCP engine swaps the key bytes (big-endian key). |
| KEY_WORDSWAP | Reflects whether the DCP engine swaps the key words (big-endian key). |
| INPUT_BYTESWAP | Reflects whether the DCP engine byteswaps the input data (big-endian data). |
| INPUT_WORDSWAP | Reflects whether the DCP engine wordswaps the input data (big-endian data). |
| OUTPUT_BYTESWAP | Reflects whether the DCP engine byteswaps the output data (big-endian data). |
| OUTPUT_WORDSWAP | Reflects whether the DCP engine wordswaps the output data (big-endian data). |
| TAG | Packet Tag |
