    Uhm,

    The Clock address is at external data. meaning it is a xdata.

    You probably need to set up some kind of addressing using a Gal22V10 to put the clock at some external address.

    Once you do that, you do something like...

    //Clear Alarm Bit
Data = XBYTE[CLOCK_ADDRESS + REGISTER_C_OFFSET];

    Once you get past that part, I have been reading about how you can set the segment. So you can access the Clock, without using Xbyte, but that is later on.

    HTH,
