ABSTRACT:
An electronic device (100) includes at least L keys (114) and a processor (506) having at least M inputs (600). Upon actuation, each one of the at least L keys (114) toggles a unique combination of N inputs of the at least M inputs (600), where each unique combination is taken from all possible combinations thereof. The at least M inputs (600) are read by the processor (506) and compared to a plurality of predetermined key patterns (806). Upon a match between the at least M inputs (600) and one of the plurality of predetermined key patterns (806), a key actuation is detected and a predetermined function may be processed in response thereto. The processor (506) may ignore simultaneous key actuations where combinations of inputs greater than N are toggled.
