the I/O banks of the Cyclone III device family.
Each I/O bank of the Cyclone III device family has a VREF bus to accommodate
voltage-referenced I/O standards. Each VREF pin is the reference source for its V
group. If you use a V
VREF pin for that group to the appropriate voltage level. If you do not use all the V
groups in the I/O bank for voltage referenced I/O standards, you can use the VREF
pin in the unused voltage referenced groups as regular I/O pins. For example, if you
have SSTL-2 Class I input pins in I/O bank 1 and they are all placed in the VREFB1N0
group, VREFB1N0 must be powered with 1.25 V, and the remaining VREFB1N[1:3]
pins (if available) are used as I/O pins. If multiple V
I/O bank, the VREF pins must all be powered by the same voltage level because the
VREF pins are shorted together within the same I/O bank.
