48.1.3.3.42.2 Function
The TRNG0 Version ID Register LSB is a read only register used to identify the
architecture of the TRNG in use. This register as well as TRNG0_VID1 should both be
read to verify the expected version.

48.1.4 Another TRNG usage example.
The TRNG can be used by a post processing pseudo-random number generator function.
For example, TRNG can be used to seed a hardware or software based implementation of
a DRBG defined by SP800-90.
Standalone True Random Number Generator (SA-TRNG).
