Bits 31:0 – INTVECTV[31:0] Initialization
Vector Value
The four 32-bit
Initialization Vector registers INTVECTVn
set the 128-bit
Initialization Vector data block that is used by some modes of operation as an
additional initial input. INTVECTV0.INTVECTV
corresponds to the
first word of the Initialization Vector, INTVECTV3.INTVECTV
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.
