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