Do the active serial (AS) configuration pins on a Stratix V device tri-state after the device enters user mode?

Description
No, the AS configuration pins on a Stratix® V device will not tri-state once the device enters user mode. The AS configuration pins will only be tri-stated when the device is in reset.
Resolution
To tri-state the AS configuration pins drive nCE high and nCONFIG low.  This will hold the FPGA in reset.
