Section 3.4 Hardware Interrupts, paragraph 1 says "See the video introducing Hwis for an overview."
does NOT link to a video, but rather to http://processors.wiki.ti.com/images/b/b2/Hwis.pdf
( I actually like the pdf, but I was surprisec when the next chapter (3.5 Software Interrupts
says "See the video introducing Swis for an overview." which is a link to a video <focus.ti.com/.../swis.mp4>
)
The use of "video" to mean PDF or MP4 seems inconsistent.
