Dear PicListers,

I would like to measure time intervals which are presented to
a Pic16C84 (possibly) as short TTL-compatible spikes.
Supposing that measuring the interval would be the pic's only task:

What would be the best time resolution I could expect using a
4 MHz pic with a Xtal?

And how about accuracy?

Is there a chance to measure with a resolution in the msec range or
isn't there?
I haven't got a clue ...

Christoph
