The 2013 Revision of the IEEE 1149.1 Standard incorporates support for dynamic data registers that can change in length and organization, unlike those fixed ones specified by the 2001 Revision. This allows, for example, definition of “excludable segments” for the boundary scan register (BSR); perfect for dealing with BSR segments in different power domains, some powered up and some not. How does this work?

What is the meaning of the word “interconnect”? As the word is applied in the field of electronics, interconnect, as defined at Techopedia.com, defines the word as follows. “An interconnect (generally speaking) is a physical or logical connection between two electronic devices or networks.” Printed circuit boards (PCB) consisting of hundreds, sometimes, thousands, of interconnected integrated circuits (IC) and other active and passive devices are essential in today’s electronic world.
