nSTATUS and CONF_DONE in user-mode

Can I toggle nSTATUS and/or CONF_DONE configuration signals after PS-configuration in user-mode?

However, all user IO pins will be held in tri-state whilst nCE is pulled high during user mode.

The statement can't be found in regular Altera documents, and at least isn't correct for all devices. I guess, it's simply erroneous. nCE is e.g. used to enable external access to a connected AS flash. You won't want other pins than the AS connected pins tristated in this case, and as far as I experienced, they aren't.
