Bits 31:0 – INTVECT[31:0] Initialization
Vector Value
The four 32-bit
Initialization Vector registers INTVECT
set the 128-bit
Initialization Vector data block that is used by some modes of operation as an
additional initial input. INTVECT0.INTVECT
corresponds to the first
word of the Initialization Vector, INTVECT3.INTVECT
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.
