Description
The DATA[7..1] pins may show up in Quartus® II software as "RESERVED_INPUT_WITH_WEAK_PULLUP" instead of "~ALTERA_DATA1~ / RESERVED_INPUT" if you are not using the Fast Passive Parallel (FPP) configuration scheme and if your Quartus II settings file (QSF) does not have the following line:
set_global_assignment -name RESERVE_DATA7_THROUGH_DATA1_AFTER_CONFIGURATION "AS INPUT TRI-STATED"
Although the Quartus II software GUI had all these options selected, it may have been deleted when modifying the QSF.
