    Overview
    The Advanced Encryption Standard (AES) and Data Encryption Standard (DES) are two com-
    monly used encryption standards. These are supported through an AES peripheral module and
    a DES CPU instruction. All communication interfaces and the CPU can optionally use AES and
    DES encrypted communication and data storage.
    DES is supported by a DES instruction in the AVR XMEGA CPU. The 8-byte key and 8-byte
    data blocks must be loaded into the Register file, and then DES must be executed 16 times to
    encrypt/decrypt the data block.
    The AES Crypto Module encrypts and decrypts 128-bit data blocks with the use of a 128-bit key.
    The key and data must be loaded into the key and state memory in the module before encryp-
    tion/decryption is started. It takes 375 peripheral clock cycles before the encryption/decryption is
    done and decrypted/encrypted data can be read out, and an optional interrupt can be generated.
    The AES Crypto Module also has DMA support with transfer triggers when encryption/decryp-
    tion is done and optional auto-start of encryption/decryption when the state memory is fully
    loaded.
