As I said in first post, now I'm trying PIC16F84, but looks like
simple things do not differ much for other midrange PICs?

About range - I would like to build just an ordinary F counter, for
general usage. Not interested much in frequencies below 1hz, but i
would like to reach maximum upper level that is reacheble without
prescaler. Possibly later I could use prescaler too, I have some
MB1502 lying around, they have prescaler inside.
But the problem is, I want at least to understand well what I am
doing, not just copy someone's design :)

I just found this:

That makes sense.
