I have a project using up to 20 16F84's on one board.
I am thinking of clocking all from one source, rather than a xtal on
each.
Assuming that's a good idea, should I have a separate Xtal oscillator,
using another IC or such, and buffers to all the PICs?
Or, can I use the clock from the first PIC, and buffer to the rest?
I was considering using a 4050, and clocking three or four PICs from one
buffer gate.
Suggestions would be welcome and appreciated, re the soundness of either
way, and a suggestion of a suitable buffer
