Hi there,

I need to use a 18,432MHz crystal with this PIC16F690 project to achieve a clean 115200bps serial comm.

Looking at the OSC values in the DEFINEs list, I can't find the value "18".

Shall I simply define the OSC as, i.e., "20" while connecting a 18MHZ crystal?

The only drawback I can see is about timing in PAUSE commands or similar. I assume the HUSART will still run from the 18MHz osc; right?

Any other problems I wouldn't see?
