Certain aspects of the disclosure are directed toward test control and test access configuration via two pins on an integrated circuit (IC). According to a specific example, an IC chip-based apparatus is used in connection with a controller for testing a target IC. The IC chip-based apparatus includes an event (capture) circuit configured and arranged to control logic states through which a static test configuration is selected for a given event detected in response to a clock signal and to a data signal respectively derived from the controller. A test-operation control circuit may be configured and arranged to test the target IC by selectively configuring each of the clock pin and the I/O pin of the controller for use as an analog test bus, data input to the controller or data output from the controller, and carrying out dynamic operations by communicating test signals via pins of the target IC.
