Intel: Is it possible to pull the INIT_DONE pin higher than the VCCIO of that bank?
Yes. It is possible.
INIT_DONE functions as an open drain, so you can input voltages below the absolute maximum rating of your device.
CRC_ERROR can also be processed in a similar way.
For details such as absolute maximum ratings, refer to the Device Handbook of each device.
Please refer to Altera's website for similar information.
