Expand description
TRNG driver, nRF5X-family
The TRNG generates 1 byte randomness at the time value in the interval 0 <= r <= 255.
Because that the he capsule requires 4 bytes of randomness at the time. 4 bytes of randomness must be generated before returning back to capsule.
Therefore this module will have to use the TRNG four times.
A counter index has been introduced to keep track of this.
The four bytes of randomness is stored in a Cell<u32> which shifted
according to append one byte at the time.
In the current implementation if done > 4 for some strange reason the random generation will be restarted
