ImpliedDisconnect
ImpliedDisconnect is a feature that provides the ability to make fast switch connection changes.
When using the RC instruction “Connect, with ImpliedDisconnect” to establish a new connection,
any existing connection to that output port is automatically broken. Thus, a connection change,
i.e. breaking an existing connection and then making a new one, can be accomplished in one
RapidConfigure cycle.
