The external flash interface is currently supported in the EPC16 and EPC4 devices.
For information about using this feature in the EPC8 device, contact Altera Applica-
tions at www.altera.com/support.
Enhanced configuration devices have a 3.3-V core and I/O interface. The controller
chip is a synchronous system that implements the various interfaces and features.
