Detecting key actuations

An electronic device 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). The at least M inputs (600) are read by the processor (506) and com...

Zusammenfassung:	An electronic device 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). The at least M inputs (600) are read by the processor (506) and compared to a plurality of predetermined key patterns. Upon a match with one of the predetermined key patterns, 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.
