== Endianness and word order ==
When writing to the AES_CTR, AES_MAC or AES_KEY0/1/2/3 register, the hardware will process the written data according to the current input endianness specified in AES_CNT. This means that the byte ordering within each word is endian swapped accordingly but the word ordering of the register remains little endian.

Swaps the bytes of 32-bit writes to AES_CTR, AES_WRFIFO, AES_KEY*FIFO according to specified endianness. AES_MAC?

=== AES_CNT.output_endianness ===

Swaps the bytes of 32-bit reads from AES_RDFIFO.

If reversed, writes to AES_KEY*FIFO and AES_WRFIFO fill the FIFO backwards. For AES_WRFIFO, this means that every 16-byte block will have its words in the reverse order, but the order of these blocks remains the same. AES_CTR is unaffected by this field. AES_MAC?

=== AES_CNT.output_word_order ===

 +
If reversed, reads from AES_RDFIFO will drain the FIFO backwards. This means that every 16-byte output block will have its words in the reverse order, but the order of these blocks remains the same.

This is the keyslot used for movable.sed encryption + AES-CBC MAC with the import/export [[FSPXI:ImportIntegrityVerificationSeed|commands]]. The keyYs used for crypto/CMAC are different, but both can be found in process9 rodata.
