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