Do I/O banks 9 - 12 support calibrated on chip termination (OCT) in Stratix II, Stratix II GX and Hardcopy II devices?

Description

Yes, I/O banks 9 - 12 in Stratix® II, Stratix II GX and HardCopy® II devices support calibrated parallel and series OCT.  There are two calibration blocks in the Stratix II devices, one in I/O bank 4 which is used for calibrated OCT in I/O banks 3, 4, 9, and 11, and the other is in I/O bank 7 which is used for calibrated OCT in I/O banks 7, 8, 10, and 12. 

The VCCIO of any I/O bank which uses calibrated OCT must match the VCCIO level of the bank which contains the calibration block for that side of the device.  For example, if you use calibrated OCT in I/O bank 9, the VCCIO level of that bank must match the VCCIO level of I/O bank 4.
