1.22 RNG Random Number
This example application shows how to use the RNG Peripheral library to generate a pseudo-random number.
Description
The RNG peripheral has two blocks. One of them is called True Random Number Generator (TRNG) and the other is called Pseudo-Random Number Generator (PRNG). The TRNG generates true random numbers that can be used as seed for the PRNG. The PRNG can generate random numbers of up to 64-bits of length. This application shows how to generate a 64-bit pseudo-random number with the help of PRNG and TRNG.
