I'll shortly need to use a 16F84 to generate a series of random pulses (truly
random, not generated by a pseudo-random algorithm). Does anyone know a
straightforward way of doing this?

I suppose the usual approach is to pass a low current through a diode,
amplify the noisy output and then produce pulses from a comparator (but
please correct me if that's wrong). I was wondering if the PIC itself
contains any inherent noisy or random signals, or can be persuaded to. If so,
genuine random pulses could perhaps be generated without any extra
components.

Then again, I could use one with a built-in ADC or comparator. If I did that,
would the noisy signal need amplifying before being input to the PIC? I can't
find anything in the application notes about these things, so any advice
would be appreciated.
