With Cyclone III, you can choose "Regular User I/O". For Cyclone II, this is not possible for some reason, but you can use the tornado_epcs_controller_atom (like Nios does). I think, this is undocumented, however. From my experience, you have to wait some micro-seconds, before the configuration-logic releases the EPCS and you can access it.
So maybe ALTASMI_PARALLEL is the better solution (I have never used it).
