// Project:     CMod S6 System on a Chip, ZipCPU demonstration project
6
//
7
// Purpose:     Defines the "Software interrupts" that may be created on this
8
//              system.  A software interrupt is one that is created by
9
//      software, but may be waited on like any other interrupt.
10
//
11
//      The biggest reason for having this is realtime clock (RTC) emulation. 
12
//      Somewhere, a hardware interrupt needs to prod the software RTC.  Then
13
//      the software RTC will generate a software interrupt so that anything
14
//      waiting on the top of the second may now be informed of that fact.
