All others
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.
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.
