This option enables the RNG peripheral, which is a random number
|
||
|
|
generator, based on internal thermal noise, that provides a
|
||
|
|
random 8-bit value to the host when read.

This option enables the RNG bias correction, which guarantees a
|
||
|
|
uniform distribution of 0 and 1. When this option is enabled, the time
|
||
|
|
to generate a byte cannot be guaranteed.
