    Not sure... sure i misunderstand what you said.
    Code:
            addr var word
        CTL CON $A0
        addr=$F0F0

SendIt:
        I2CWRITE PORTD.6, PORTD.7,CTL,addr,[$F1F2]
        pause 50
        goto sendit
    will looks like...

    But yeah.. on some device, the Address can be mixed with the ControlByte. EEPROMs such as some 24C04, c08 and c16 work like that.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
