15.15.6.6 Use Default Pins for VREFs
Select this check box to set default VREF pins and unset non-default VREF pins. If you unselect this option when setting a new VREF technology, no VREF pins are set. If you unselect this option when default VREF pins are already set, it unsets them.
Click More Attributes to set the low-power mode and input delay. (These attributes are not supported in IGLOOe, Fusion, ProASIC3E, or RTAXS devices.)
Click Apply to assign the selected I/O standards to the selected bank. Any previously assigned I/Os in the bank that are no longer compatible with the standards applied are unassigned.
