16F876 counter speed? |

Can anybody tell me what is the maximum reading speed for
the 16-bit counter in 16F876-20SP?
By using same PIC, If I use fast I/O, what is the maximum speed I can
use to read digital input?
Thanks!

Better to explain what you are trying to do. At 20MHz each instruction takes 200ns. So to answer your question, you can read the input every 200ns but that is it. At 200ns you can't do anything with it. So the real question would be how fast can I read an input and do this with it. |
