The only software instructions which explicitly cause supervisor traps appear to be SVC, BPT, and FLAG. Since these traps are already used for something else either in the OS, debugger, or compiler, I need to find a way to generate a trap to one on the unused or less innocuous trap numbers. Anyone know how?
