// Project:     CMod S6 System on a Chip, ZipCPU demonstration project
6
//
7
// Purpose:     Defines particular definitions specific to the ZipCPU. 
8
//              Originally designed to be specific to the ZipSystem, this has
9
//      been adjusted to just the CPU, since the CMod S6 doesn't have the full
10
//      ZipSystem implemented.
