It is missing some detail about how the interrupts operate, but: a) It's a blog post not a reference manual. It's aim appears to be clear up some confusion about terminology (and having been using a Cortex M4 for a year I've spent a fair amount of time trying to reconcile conflicting documentation). b) It's only the first blog post in an intended series. Who knows what's going to get covered next. Even though I've got most of this sorted out in my head by now, it's still helpful to me to have it put clearly in one place (even if it's just so that I have a link to give to newer members of my team).
