AUX0 Mode. Definition depends upon the value of the 4 Cipher Mode and Extended Cipher Mode
bits, and Encrypt/Decrypt bit:
Cipher Mode. Used in combination with bits 56:57 (Extended Cipher Mode) to select the cipher
mode for AES operation. See
Encrypt/Decrypt. If set, AESU operates the encryption algorithm; if cleared, AESU operates the
decryption algorithm.
0 Perform decryption
1 Perform encryption
Note: This bit is ignored in CTR, SRT, CMAC, and XCBC-MAC cipher modes.
• GCM Cipher Mode (ECM=10, CM=01) and Encrypt (ED=1): Specifies GHASH mode—performs
• XCBC-MAC, CMAC Cipher Modes (ECM=10, 01, CM=10): Do Not Generate Final MAC
