    Connecting a parallel flash to achieve what?

    The CPLD will do nothing unless you download a logic configuration you designed before. The function of each pin will be defined in your logic, e.g. address signals driving the flash address lines. You can give each pin a symbolic name according to it's function, may be equal to the connected flash pin name.

    There isn't enough logic in those devices to operate a parallel FLASH device. So, I suggest you don't bother and focus your playing around on something else.

    Cheers,
