AES_RESET=B_0x0
TRNG_POSTP_CR register
| AES_RESET | Reset AES post processing. When writing a 1, the AES post processing is reinitialized, resulting in a new key and new state generation before 128-bit random words generation. The ‘1’ written is frozen until it is seen by RNG core clock domain after resynchronization. Then it is automatically reset. It also reruns analog source health tests. 0 (B_0x0): No effect 1 (B_0x1): Reset AES core |
| NB_LOOP_AES | NB_LOOP_AES is the number of 128-bit words got from the noise source that have to be processed by AES for generating a single 128-bit random word. By default, this value is set to 2 (128 bits generated before an AES processing). 0 value means 16 loops. A new AES processing is started only when the previous one is completed. |
| NB_RND_REINIT | Number of 128-bit random words generated before AES automatically resets. This number is in the range of 1 to 65535 words. Value 0x0000 means that AES is never reinitialized. |
