	<p> The Bit or pin individually can set the pull-up and inverton on the chip.  The On/Off Msg checkboxs are used to allow messages on change.  The status will change anyway regardless of the on/off msg </p>
	<p> The debounce sets the time required for a state to be steady before changing the status and sending a message</p>
