Abstract
A first bank or a second bank of storage locations of a control store of a data processing system is enabled in response to one of a plurality of test signals received as parallel inputs by two multiplexer devices. Only one of the multiplexers is enabled at a given time in response to the polarity of one of the test signals selected from the inputs of the multiplexer devices.
