DATA

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

RND_IRQ_EN : 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 : To enable IRQ generation when a health test fails
bits : 2 - 2 (1 bit)
access : read-only

Enumeration:

End of enumeration elements list.

AESKG_MEU : 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_MEMPROTE : 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 : 4 - 4 (1 bit)

AESKG_MEMPROTA : 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 : 5 - 5 (1 bit)

RSV16 : None
bits : 16 - 16 (1 bit)

RSV17 : None
bits : 17 - 17 (1 bit)

RND_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.

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

Enumeration:

End of enumeration elements list.

HTS : Health test status. This bit shall be read when On-demand health test is completed (ODHTS=0) to check the result. This bit is also set when a continuous health test reports an error, IRQ is generated if HEALTH_EN=1. Write 1 to clear this bit.
bits : 2 - 2 (1 bit)

Enumeration:

End of enumeration elements list.

SRCFAIL : Entropy source has failed. IRQ is generated if HEALTH_EN=1. Write 1 to clear this bit.
bits : 3 - 3 (1 bit)

Enumeration:

End of enumeration elements list.

AESKGD_MEU_S : Automatically AES transfer on going
bits : 4 - 4 (1 bit)

RSV16 : None
bits : 16 - 16 (1 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)
