AES_BUSY=B_0x0, AES_INIT=B_0x0, AES_KEY_LD=B_0x0
TRNG_POSTP_SR register
| AES_INIT | AES Post processing has been fully initialized (key and state) and is ready for generating 128-bit random words. 0 (B_0x0): AES core is not initialized (no key or state set). 1 (B_0x1): AES core is fully initialized. |
| AES_KEY_LD | AES random key has been generated and loaded in AES key register. 0 (B_0x0): AES core is waiting for 128 random bits from the entropy sources for generating its key 1 (B_0x1): AES key register has been loaded with a random key. |
| AES_BUSY | AES core is busy, generating a random value. 0 (B_0x0): AES core is idle 1 (B_0x1): AES core is busy. |
| AES_HEALTH_DONE | AES-CMAC health test is completed |
| AES_K12_ERROR | Health test error on AES-CMAC sub-keys generation |
| AES_DOUT_ERROR | Health test error on AES-CMAC output generation |
