Abstract
A control circuit is disclosed that comprises a resistor and a switch network. The switch network is configured to transition between a plurality of states corresponding to a plurality of operational modes of a surgical instrument. In a first phase of a control signal, the control circuit is configured to communicate surgical instrument information to a surgical generator. In the second phase of the control signal and when the at least one switch of the switch network is in a first state of the plurality of states, the control circuit is configured to provide an output corresponding to one of the plurality of states. In the second phase of the control signal and when the at least one switch of the switch network is in a second state of the plurality of states, the control circuit is configured to provide a second output.
