System Overview
3.2.11 Random Number Generator
The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain.
The data is suitable for use in cryptographic applications.
Output from the random number generator can be used either directly or as a seed or entropy source for software-based random num-
ber generator algorithms such as Fortuna.
