All Nexus / Device Constraint Editor: How can the user set the DONE, INITN, and PROGRAMN pins of Nexus devices as GPIO during user mode?

Users need to program the feature row with the .fea file generated during the design flow (Note: If changes are made on the Global settings, user needs to rerun the design flow to re-generate a new .fea file that reflects the changes on the Global settings with DONE, INITN, and PROGRAMN pins set to DISABLED). 

Program the feature row and users will be able to use them as GPIOs during user mode.

WARNING: These feature row bits are OTPs (One-time programmable). Disabling all of these config pins could limit what the user can do to the device as they will not be able to re-configure using different interfaces SSPI or I2C (instead of JTAG) as these pins are required during enabling of these interfaces.
