ABSTRACT:
An electronic device, with a plurality of logic stages for functional collaboration, is provided with selection means for selectively operating the plurality of stages to form either a sequential logic circuit or a combinatorial logic circuit. This enables conversion of sequential logic circuitry into combinatorial logic circuitry for the purpose of effective I.sub.DDQ -testing.
