Description
CBC Initialization Vector 3 [127:96]. Bits [127:96] of the IV for the CBC AES Mode.
Change this register only when both A and B channels are IDLE. (A and B start bits, SB
Memory Offset 000h and 004h, bit 0 = 0). This register must be programmed with the IV
prior to starting an AES CBC mode encryption or decryption.
Description
Random Number. Returns a 32-bit random number. Check the TRNG_VALID bit (SB
Memory Offset 054h[0]) before reading this register. If the status bit (TRNG_VALID) is
1, the value in this register is ready for use. A 0 in the status bit indicates that the ran-
dom number is in the process of being generated.
