QT60320D Features

* permit the construction of entirely new classes of keypanels never before contemplated, such as touch-sliders, back-illuminated keys, and arbitrary shape keypanels, all at very low cost. The QT60320D uses an asynchronous serial (uart) interface running at 9600 baud to allow key data to be extracted
