The nIO_PULLUP pin is a dedicated input that chooses whether the
internal pull-up resistors on the user I/O pins and dual-purpose
configuration I/O pins (nCSO, ASDO, DATA[7..0], nWS, nRS, RDYnBSY,
nCS, CS, RUnLU, PGM[2..0], CLKUSR, INIT_DONE, DEV_OE, DEV_CLR)
are on or off before and during configuration. A logic high (1.5, 1.8, 2.5,
3.3 V) turns off the weak internal pull-up resistors, while a logic low turns
them on.
Stratix II GX devices also offer a new power supply, V

on the configuration input pins and JTAG pins. V

CLKUSR. The VCCSEL pin allows the V

the configuration inputs. Therefore, when selecting the V
you do not have to take the V
inputs into consideration. The configuration input pins, nCONFIG, DCLK
(when used as an input), nIO_PULLUP, RUnLU, nCE, nWS, nRS, CS, nCS,
and CLKUSR, have a dual buffer design: a 3.3-V/2.5-V input buffer and a
1.8-V/1.5-V input buffer. The V
