Abstract
A data processing system (10) implements state machine (82) and register logic (80) such that no external control or data is required during execution of a dual scan path test operation. Prior to execution of the dual scan path test operation, a user of data processing system (10) initializes a system with a plurality of values which will be used during execution of the dual scan path test operation. After initialization, data processing system (10) executes the dual scan path test operation automatically and requires no additional information from the user.
