Name:
Access Type:
• IVx: Initialization Vector x
The four 32-bit Initialization Vector registers set the 128-bit Initialization Vector data block that is used by some modes of
operation as an additional initial input.
IV1 corresponds to the first word of the Initialization Vector, IV4 to the last one.
These registers are write-only to prevent the Initialization Vector from being read by another application.
For CBC, OFB and CFB modes, the Initialization Vector corresponds to the initialization vector.
For CTR mode, it corresponds to the counter value.
