Initialization/Application Information
The intended general operation of the RNG is as follows:
1. Reset/initialize.
2. Write to the RNG entropy register (optional).
3. Write to the RNG control register and set the interrupt mask, high assurance, and GO bits.
4. Poll RNGSR[OFL] to check for random data in the FIFO.
5. Read available random data from RNGOUT.
6. Repeat steps 3 and 4 as needed.
