off before and during configuration. A logic high
(1.5-V, 1.8-V, 2.5-V, 3.3-V) turns off the weak
internal pull-ups, while a logic low turns them
on.
The

3-bit configuration input that sets the Stratix or
Stratix GX device configuration scheme. See
Table 11–2
These pins can be connected to V
I/O bank they reside in or ground. This pin uses
Schmitt trigger input buffers.
Configuration control input. Pulling this pin low
during user-mode causes the FPGA to lose its
configuration data, enter a reset state, tri-state
all I/O pins. Returning this pin to a logic high
level initiates a reconfiguration.
If your configuration scheme uses an
enhanced configuration device or EPC2
device,
