Random Number Generator (RNG)
27.3.4 RNG Core Engine
The Core Engine Block contains the logic used to generate random data. The logic within the Core
Engine contains the internal shift registers as well as the logic used to generate the two oscillator
based clocks. This logic is "brainless" and must be controlled by the Control Block. The Control
Block controls how the shift registers are configured as well as when the oscillator clocks are
turned on.
27.4
The intended general operation of the RNG is as follows:
27-6
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 RNG status register for FIFO level
5. Read available random data from RNG output FIFO
6. Repeat steps 3 and 4 as needed
