  About: Is an interface for the AES Engine (CCM Encrypt/Decrypt only), you can only use predetermined keyslots though.
  Note: When encrypting, the output buffer size must include the MAC size, when decrypting, the input buffer size must include MAC size.
  MAC: When decrypting, if the MAC is invalid, 0xC9010401 is returned. After encrypting the MAC is located at inputbufptr+(totalassocdata+totaldatasize)
