TRNG Random Number Generator. 0x400B5000 0x00 0x1000 registers TRNG TRNG interrupt. 4 CTRL TRNG Control Register. 0x00 0x00000003 ODHT On Demand Health Test. 0 1 RND_IE To enable IRQ generation when a new 32-bit Random number is ready. 1 1 HEALTH_EN Health Test Enable. 2 1 AESKG_USR User block AES Key Gen. 3 1 AESKG_SYS System block AES Key Gen. 4 1 KEYWIPE Wipe Key. 15 1 STATUS Data. The content of this register is valid only when RNG_IS = 1. When TRNG is disabled, read returns 0x0000 0000. 0x04 read-only RDY 32-bit random data is ready to read from TRNG_DATA register. Reading TRNG_DATA when RND_RDY=0 will return all 0's. IRQ is generated when RND_RDY=1 if TRNG_CN.RND_IRQ_EN=1. 0 1 ODHT On demand health test. 1 1 HT Health test status. 2 1 SRCFAIL Source Fail. 3 1 AESKGD AES Key Gen Status. 4 1 LD_CNT Load Count. 24 8 DATA Data. The content of this register is valid only when RNG_IS = 1. When TRNG is disabled, read returns 0x0000 0000. 0x08 read-only DATA Data. The content of this register is valid only when RNG_IS =1. When TNRG is disabled, read returns 0x0000 0000. 0 32
