STATUS

DATA

ODHT : Start On-Demand health test.
bits : 0 - 0 (1 bit)

RND_IE : To enable IRQ generation when a new 32-bit Random number is ready.
bits : 1 - 1 (1 bit)

Enumeration:

End of enumeration elements list.

HEALTH_EN : Enable IRQ generation when a health test fails.
bits : 2 - 2 (1 bit)

AESKG_USR : AES Key Generate. When enabled, the key for securing NVSRAM is generated and transferred to the secure key register automatically without user visibility or intervention. This bit is cleared by hardware once the key has been transferred to the secure key register.
bits : 3 - 3 (1 bit)

AESKG_SYS : AESKG_SYS.
bits : 4 - 4 (1 bit)

KEYWIPE : To wipe the Battery Backed key.
bits : 15 - 15 (1 bit)

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.
bits : 0 - 0 (1 bit)

Enumeration:

End of enumeration elements list.

ODHT : On-Demand health test status.
bits : 1 - 1 (1 bit)

HT : Health test status.
bits : 2 - 2 (1 bit)

SRCFAIL : Entropy source has failed.
bits : 3 - 3 (1 bit)

AESKGD : AESKGD.
bits : 4 - 4 (1 bit)

LD_CNT : LD_CNT.
bits : 24 - 31 (8 bit)

DATA : Data. The content of this register is valid only when RNG_IS =1. When TNRG is disabled, read returns 0x0000 0000.
bits : 0 - 31 (32 bit)
