These high priority interrupts can interrupt * normal processing but execute outside of OS (although they can "get back * into the game" via a PendSV interrupt). * * In the normal course of things, interrupts must occasionally be disabled * using the irqsave() inline function to prevent contention in use of * resources that may be shared between interrupt level and non-interrupt * level logic.
