EHR_DATA[n]

nRF5340 Product Specification

Address offset: 0x114 + (n × 0x4)

The entropy holding registers (EHR) hold 192-bits random data collected by the TRNG.

The initial EHR_DATA[0] register holds the least significant bits [31:0] of the random data value.

These registers are readable if register TRNG_VALID is Valid. Reading register EHR_DATA[5] will clear the content, reset TRNG_VALID, and start a new 192 bits collection period.
