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-up resistors.

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.
Optional user-supplied clock input synchronizes the initialization
of one or more devices. This pin is enabled by turning on the
Enable user-supplied start-up clock (CLKUSR) option in the
Status pin used to indicate when the device has initialized and is
in user-mode. When nCONFIG is low and during the beginning
of configuration, the INIT_DONE pin is tri-stated and pulled
high due to an external 10-kΩ pull-up resistor. After the option
bit to enable INIT_DONE is programmed into the device
(during the first frame of configuration data), the INIT_DONE
pin goes low. When initialization is complete, the INIT_DONE
pin is released and pulled high and the device enters user mode.
Thus, the monitoring 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.
The functionality of this pin changes if the Enable OCT_DONE
option is enabled in the Quartus II software. This option
controls whether the INIT_DONE signal is gated by the
OCT_DONE signal, which indicates the Power-Up OCT
calibration is complete. If this option is turned off, the
INIT_DONE signal is not gated by the OCT_DONE signal
Optional pin that allows you to override all tri-states on the
device. When this pin is driven low, all I/O pins are tri-stated;
when this pin is driven high, all I/O pins behave as programmed.
This pin is enabled by turning on the Enable device-wide
output enable (DEV_OE) option in the Quartus II software.
