AS Flash pins access

Skip this question. I figured it out by trial and error. No thanks to Altera Documentation. I guess they expect everyone to blindly follow the NIOS/megafunction path without actually knowing how the hardware works. Keeps us locked into their product that way.

For those of you interested and who actually write your own hardware drivers rather than using the cookbook megafunctions:

The "Enable input tri-state on active configuration pins in user mode" check box will conflict with user mode access on the configuration pins.
