// Project:     CMod S6 System on a Chip, ZipCPU demonstration project

// Purpose:     An instantiation of a generic interface to a wishbone on a
8
//              device.  This particular instantiation uses a simplified
9
//      interface over a Digilent Adept Asynchronous Parallel Port Interface
10
//      (DEPP)--useful for working with the CMod-S6.
