9.4.1.2.5 Subsequence: Initialize F8 AES Core Mode
The steps for configuring the AES for F8 mode is as follows:
- Enable F8 Mode by setting the F8 bit in the AES_CTRL register.
- Select the counter width by programming the CTR_WIDTH field in the AES_CTRL register.
- Set the key size to 128 bits by setting 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.
