Hi all. I know there have been discussions about overclocking the
f84-04, but has anyone overclocked the f87x? Specifically the 16f877-04?
I want to take it up to 20Mhz, and I'm wondering if it will work. Also,
at those speeds, will I run into problems if I try to breadboard? Now my
final question, can I receive a 250kps data stream using the UART if my
clock is at 4Mhz? Will the buffer overflow if I'm not exceedingly quick
in my processing of the data? I also don't want to spend 90% of my time
in the ISR actually receiving the data.

Thanks,

Josh Koffman
