Abstract
Disclosed are a circuit and method for providing automatic termination for a small computer systems interface ('SCSI') bus. The circuit resides within a bus controller comprising (1) a control circuit for controlling transmission of data on a bus and for providing an interface between the bus and a computer system for communication of the data therebetween and (2) a first bus port and a second bus port, each of the first and second bus ports permitting a device to be coupled thereto for communication with the control circuit via the bus, the bus controller being at an end of the bus when a single one of the first and second bus ports is coupled to a device and being in a middle of the bus when both the first and second bus ports are coupled to devices. The circuit of the present invention is coupled to the first and second bus ports and is capable of coupling a terminating circuit to the bus as a function of a presence of devices coupled to the first and second bus ports, the bus requiring coupling of the terminating circuit when the bus controller is at the end of the bus.
