| 摘要 |
An interface between a programmable device and an external device coupled to the programmable device is described. The interface includes configurable control pins for providing control signals to the external device. The programmable device may be a field programmable gate array and the external device may be a nonvolatile memory. In some cases, the interface may be used to provide a byte-wide, or other parallel, interface. After configuration, the pins of the interface may be reclaimed and used for other purposes, such as accessing one or more external memories or other devices connected to a bus.
