Abstract

In a particular embodiment, a method of monitoring interrupts during a power down event at a processor includes activating an interrupt monitor to detect interrupts. The method also includes isolating an interrupt controller of the processor from the interrupt monitor, where the interrupt controller shares a power domain with the processor. The method also includes detecting interrupts at the interrupt monitor during a power down time period associated with the power down event.
