Basically on a vax, you could poke a register and it would cause a low-priority interrupt. They were often used for 'split priority' interrupt handlers where you did the minimum amount of work in the first interrupt and then triggered a SWI for the rest. The advantage being that the SWI could be pre-empted by another high-priority hardware interrupt.Received on Tue Nov 11 2003 - 00:16:41 UTC
