If using bytes then the format would be something like
Code:
I2CWRITE SDApin,SCLpin,$A0,$00,[data1,data2,... etc etc]

If using word variables the format would be something like this
Code:
I2CWRITE SDApin,SCLpin,$A0,$00,[data1.lowbyte,data1.highbyte, data2.lowbyte,data2.highbyte, etc etc]
IC2READ would have the corresponding values in its statement
