Notes to Table 4–27:
(1) The Stratix II GX device V_CCIO voltage level support of 1.8 to 5% is narrower than defined in the Normal Range of
the EIA/JEDEC standard.
(2) This specification is supported across all the programmable drive settings available for this I/O standard as shown
in Stratix II GX Architecture chapter in volume 1 of the Stratix II GX Device Handbook.
