WAKE-UP SYSTEM AND METHOD FOR POWERED SURGICAL INSTRUMENTS The present disclosure is directed to an electromechanical surgical system having an end effector and an adapter assembly (14) for selectively interconnecting the end effector and a hand held surgical instrument (10). A one-wire bidirectional serial communications interface or bus (36) extends through the end effector, the adapter assembly (14), and the hand-held surgical instrument (10). The hand-held surgical instrument (10) includes a master circuit (34) coupled to the bus (36) and configured to identify or control the adapter assembly (14) or the end effector. A power source (44) is couplable to the bus (36) and configured to provide power to the adapter assembly (14) or the end effector. A first switch connects the master circuit (34) to the bus (36) and a second switch connects the power source (44) to the bus (36). A processor (32) controls operation of the hand-held surgical instrument (10). The controller (30) has a wake-up pin (40) connected to the bus (36) and is configured to receive a presence pulse from the adapter (14) or end effector. Col C, C:> CY) Cr, c 0o 2, |
