Because Microchip does not specify anything about how their "random" numbers are generated, I would be strongly disinclined to make any assumptions about randomness though I would expect that it's unlikely that anyone would go through the trouble of exploiting any non-randomness for anything except highly-sensitive cryptographic systems, and for those I would strongly recommend doing the programming in-house anyway. Other- wise, my guess would be that Microchip is using something reasonably ran- domish, but nothing that can be relied on as such. PS--In the original specification for closed-captioning, it says that field 2 is supposed to contain "random" data. Can anyone think of any reason why something would be spec'ed to be "random" with no indication of required spectral properties, non-correlation, etc.?
