    DESCRIPTION
    The X24256 is a CMOS Serial E
    organized 32K x 8. The device features a serial inter-
    face and software protocol allowing operation on a
    simple two wire bus.

    These pins have internal pull downs, so they are read
    as LOW if not connected.
    A WP pin, when pulled HIGH prevents any nonvolatile
    writes to the array. When not connected WP is pulled
    LOW, so the device is not normally protected.
