  • System for automatically terminating a daisy-chain peripheral bus with either single-ended or differential termination network depending on peripheral bus signals and peripheral device interfaces
    Patent number: 5864715
    Abstract: A peripheral device interface is coupled between a computer system bus and a peripheral bus. The peripheral device bus includes a signal line which can be configured in either a single-ended or a differential configuration. A peripheral controller is coupled to the computer system bus. A single-ended signal line interface circuit is coupled between the peripheral bus signal line and the peripheral controller, and may be selectively enabled in response to a control signal. A differential signal line interface circuit is also coupled between the peripheral bus signal line and the peripheral controller and also may be selectively enabled in response to a control signal. The peripheral controller generates the control signals for the single-ended signal line interface circuit and the differential signal line interface circuit.
