configuration pins are not enabled in the Quartus II software, they are
available as general-purpose user I/O pins. Therefore during
configuration, these pins function as user I/O pins and are tri-stated with
weak pull-ups.

circuitry must be able to detect a low-to-high transition. This
pin is enabled by turning on the Enable INIT_DONE output
option in the Quartus II software.
Optional pin that allows the user to override all tri-states on
the device. When this pin is driven low, all I/Os are tri-stated.
When this pin is driven high, all I/Os behave as programmed.
This pin is enabled by turning on the Enable device-wide
output enable (DEV_OE) option in the Quartus II software.
Optional pin that allows you to override all clears on all
device registers. When this pin is driven low, all registers are
cleared. When this pin is driven high, all registers behave as
programmed. This pin is enabled by turning on the Enable
device-wide reset (DEV_CLRn) option in the Quartus II
software.
