Abstract
A system and method that use the TCK and TMS to transmit address and data. IEEE 1149.1 based tools can use the system and method without modification to make IEEE 1149.1 TAPs appear and disappear, add compliance-enable circuits without pins and broadcast commands to IEEE P1687 instruments. The system and method use Test-Logic-Reset sequences with Run-Test-Idle to enable an on/off switch of various DFT capabilities. IEEE 1149.1 compliant TAP interfaces disappear to pass-through wires using the system and method. The sequences communicate an 'address' which enables one or more of the TAP interfaces and a 'command'. The system and method has benefits for IEEE P1687 instrument chains and on-chip routing of the P1687 network.
