Description / Abstract:
This standard defines test logic that can be included in an
integrated circuit to provide standardized approaches to:
-Testing the interconnections between integrated circuits
once they have been assembled onto a printed circuit board or other
substrate
-Testing the integrated circuit itself
-Observing or modifying circuit activity during the
component's normal operation
The test logic consists of a boundary-scan register and other
building blocks and is accessed through a test access port
(TAP).
