    Note that this has nothing to do with Keil.

    "Fanout" would have to be specified in terms of some standard load. That was fine way back in the days when all your logic was 74-series TTL - but is rather meaningless to today's microcontrollers.

    Therefore, you just need to look at the output capabilities - current, capacitance, etc - specified in the Datasheet, and ensure that your load does not exceed them!
