This paper describes an Addressable Shadow Protocol device that is capable of providing connectivity between a backplane resident IEEE 1149.1 test bus master and a plurality of 1149.1 device chains existing on a board or module. The enhanced device provides for improvement in test, emulation, programming, and other applications based on the 1149.1 test bus.
