Description of the invention (In another embodiment of the present invention, the computer system connected to the PC card directly issues a command to make the PC. Card go to sleep or return to normal State_. The two states are still the same as described above, and will not be repeated here. The third diagram proposes a connector supporting DnS function. The connector includes a matching socket 2 2 and a plug 2 4. Among them, socket 2 The contact of 2 includes a contact that sends a sleep state signal SLEEP / WAKE, and a contact connected to the ground terminal GND; and the plug 24 is in phase with the two contacts SLEEP / WAKE and GND. The corresponding two pins have an electrical connection 2 6 〇 When the connector is connected, that is, the plug 2 4 is inserted into the socket 2 2, due to the role of the electrical connection 2 6, the contact s LEEP / WAKE and the contact GND It is at the same potential, so the signal level (L e -ve 1) of the contact SLEEP / WAKE is zero: electric weeping. At this time, the PC card knows that the connector is normally connected, and everything is in normal: state. __ Then _, The fourth figure discloses a sleep power-saving control circuit 20, in which a pull high nozzle R is connected to a power source vCc as a power source for providing a signal state; the input of the sleep power-saving control circuit 2 0 is sleep Status signal SLEEP / WAKE, for example, connected to the socket shown in the third picture above. 22 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. 0 Please read the precautions on the back before filling in this page.) The output of the sleep power-saving control circuit 20 includes three signals, which are sent to the high-speed Ethernet controller 1 2, the high-speed Ethernet non-shielded twisted-pair transceiver 14 and the high-speed static memory I 6, among which ' The signal transmitted to the high-speed Ethernet unshielded twisted-pair transceiver 14 is directly derived from the sleep state signal SLEEP / WAKE input above, and the signal transmitted to the high-speed static memory 16 is sleep 11 paper standards Applicable to China National Standard (CNS) A4 specification (2'10 × 297 · mm) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention () Sleep status signal s LEEP / w AKE Warp-NOT AND Gate (NANDG ate), and finally the signal transmitted to the high-speed Ethernet controller 12 is a pulse signal generated by the sleep state signal SLEEP / WAKE to trigger a one-shot circuit. Now referring to the third and fourth diagrams, as described above, when the connector is normally connected, the sleep state signal S L E E P / W A K E = 0, and the PC card is in a normal state at this time. Once the plug 2 4 is separated from the socket 2 2, the contact SL EE P / WAKF becomes a floating (F 1 〇ating) state.
