摘要：A logic module is disclosed for construction in an integrated digital circuit forpromoting testing of the integrated circuit. A latch module is provided for functioning asa latch, as a back-coupled shift register, and in one embodiment of the invention as alinear shift register. The latch module is formed of a plurality of basic cells each of whichhas a flip-flop with associated logic gates, one of which is an exclusive OR gate. The latchmodule also has an input, parallel data inputs and parallel data data outputs. Forfunctioning in the back- coupling mode, an exclusive OR gate is connected between atleast one of the flip-flops and the input to the latch module.
