Device having configurable breakpoint based on interrupt status

摘要

A processor device with debug capabilities has a central processing unit, an interrupt controller, a status unit operable to be set into a first mode indicating an interrupt has occurred or in a second mode indicating normal execution of code, and a debug unit coupled with said status unit and comprising a configurable breakpoint, wherein a condition can be set that a breakpoint is only activated if the device is operating in an interrupt service routine.
