KEY2W
• KEY2W: Key 2 Word
The two 32-bit Key 2 Word Registers allow to set the 64-bit cryptographic key used for encryption/decryption.
KEY2W0 corresponds to the first word of the key and KEY2W1 to the last one.
These registers are write-only to prevent the key from being read by another application.
Note:
KEY2WRx registers are not used in DES mode.
