9.4.1.2.6 Subsequence: Initialize XTS AES Core Mode
The steps for XTS mode configuration are as follows:
- Enable XTS Mode by configuring the XTS field in the AES_CTRL register.
- If the XTS field in the AES_CTRL register indicates that the AAD length is required, load the AAD length in the AES_AUTH_LENGTH register.
- Load the AES Initialization Vector Input n (AES_IV_IN_n) registers at offset 0x040 to 0x04C.
