    Hi guys,
    Currently studying a pcb board which contain a lmb204bfc LCD and it is interfaced with a PIC18F8722 mcu. I've attached a data sheet on the lmb204bfc LCD for you guys to review anytime in this discussion.
    I found out that we can choose the data bits for this LCD either 4 bits (using DB4 to DB7) or 8 bits (using DB0 to DB7). What I want to know is, if I want to use 4 bits, that means I have to connect DB4 to DB7 to my mcu. Then what happen to DB0 to DB3? Do I connect DB0 to DB3 to my mcu also or I left it disconnect?

    Leave DB0 to DB3 not connected.
