Refer toTable 7–22 on page 7–94 for a consolidated list of configuration outputpins.The V IH of 3.3 V or 2.5 V configuration devices will not be met when theV CCIO of the output configuration pins are 1.8 V or 1.5 V. Level shifterswill be required to meet the input high level voltage threshold V IH .Note that AS mode is only applicable for 3.3-V configurations. If I/Obank 3 is less than 3.3 V, level shifters are required on the output pins(DCLK, nCSO, ASDO) from the Stratix II or Stratix II GX device back to theEPCS device.Altera Corporation 7–13May 2007 Stratix II Device Handbook, Volume 2
