9.4.1.2.4 Subsequence: Initialize F9 AES Core Mode
The steps for configuring the AES for F9 mode is as follows:
- Enable F9 Mode by setting the F9 bit in the AES_CTRL register.
- Set the key size to 128 bits by programming the KEY_SIZE field to 0x1 in the AES_CTRL register.
- Load the AES Initialization Vector Input n (AES_IV_IN_n) registers at offset 0x040 to 0x04C.
