Description
Writable Key 3. Bits [127:96] of the Writable Key for the Security Block. This register
should not be changed during an AES encryption or decryption operation. To prevent
one process from reading the key written by another process, this register is not read-
able.
Description
CBC Initialization Vector 0 [31:0]. Bits [31:0] of the initialization vector (IV) for the CBC
AES mode (Cipher Block Chaining). Change this register only when both A and B chan-
nels are IDLE. (A and B start bits, SB Memory Offset 000h and 004h, bit 0 = 0). This reg-
ister must be programmed with the IV vector prior to starting an AES CBC mode
encryption or decryption.
