AES Cryptoprocessor Overview
10.1.6.3.1 Data Format and Byte Order
The following examples show how the data must be submitted to the AES Engine. Because the AHB slave
interface is mostly transparent for data (no data modifications), the alignment for the register interface is
identical, as described in the following examples.

NOTE:
The byte in bold type is a first byte of the key or message.
