Henrik,
The only reference I can see to "open-drain" within my PIC18f14K50 datasheet is specifically in reference to the Data and Clock pins for the MSSP module *when set to* i2c mode. I guess I'll find out tonight when I whack the PIC back into the development board and try to run i2c through other (non MSSP module) ports/pins. Worst case scenario I can butcher the circuit board to accommodate the use of the correct i2c pins, but it would be nice to be able to avoid that.
