Abstract

See full text

A multifunction control circuit is responsive to a condition of the input power to selectively activate alternative functionality. In one embodiment, a μC is configured to monitor the input voltage, looking for a gap in the input voltage of a pre-determined duration, which indicates to the μC that the second (or additional) function is desired. This embodiment of the control circuit includes a 5 volt regulator configured to ensure sufficient power to the μC during an interruption of input power intended to present a function change signal. Alternatively, the control circuit may be constructed to monitor a change in the polarity of the input power and change functionality in response to changes in the polarity of applied voltage.
