Cryptographic processor (CRYP) RM0090
732/1731 DocID018909 Rev 11
cryptographic algorithm (for the AES, the block length is four 32-bit words, but swapping
only takes place at word level, so it is identical to the one described here for the TDES).
Note: The same swapping is performed between the IN FIFO and the CRYP data block, and
between the CRYP data block and the OUT FIFO.
