Can i leave the unused receiver pins (DINRXN/P, RXD0~15) unconnected?

    KGY,
    Yes you can.
    A more conservative approach would be to use weak pulldowns on the parallel RXD, RXCLK, RKxSB outputs, but this is not required. These pins will be tristated (except during power on reset).

    However, you can read through this post to get a little more insight.

    The receiver will need to be enabled for brief period after power up. This is detailed in the power on reset section.
