EVENT VECTOR TABLE OVERRIDE

摘要

In an embodiment, a system may include a processor that handles a number of events. These events may include general purpose interrupts (GPIs) assigned to particular devices in the system. Addresses for event service routines appropriate for particular events may be stored in an event vector table (EVT). In a system with a number of devices that utilize the processor's resources, some interrupts may be overloaded, that is, assigned to more than one device. If an overloaded interrupt occurs, the processor may override the EVT entry and select and address supplied by a system controller at a set of reset vector pins.
