0110_1 — Reserved
0111_1 — Reserved
1000_1 tls_ssl_block TLS/SSL generic block cipher (new for SEC2.1)
1001_1 tls_ssl_stream TLS/SSL generic stream cipher (new for SEC2.1)
1010_1 raid_xor XOR 3 sources together (new for SEC2.1)
others — Reserved
Notes: 1. Descriptor types from the SEC1.0, which have 0 in the last bit, are listed first, followed by the newer SEC 2.x
types, which have 1 in the last bit.
2. Type 0000_0 is for AES-CTR operations. Type 0001_0 also supports AES-CTR, however to use AES-CTR with
0001_0, the user must prepend zeros to the AES-Ctx before loading the AES Context Registers.
3. Type 1100_0 is for AES-CTR operations with HMAC. Type 0010_0 also supports AES-CTR with HMAC,
however to use AES-CTR with 0010_0, the user must prepend zeros to the AES-Ctx before loading the AES
Context Registers.
