Abstract
A computer system that allows a central device to transmit identification information to multiple peripheral devices is disclosed. The central device is coupled to multiple peripheral devices via respective point-to-point communication links. The central device may send a first identifier to a particular peripheral device of the multiple peripheral devices using a particular common mode voltage on a particular point-to-point communication link that is coupled between the central device and the particular peripheral device.
Claims20
An apparatus, comprising:
- a plurality of peripheral devices;
- and
- a central device coupled to the plurality of peripheral devices via respective ones of a plurality of point-to-point communication links, wherein the central device is configured to:
- send a first identifier to a first peripheral device of the plurality of peripheral devices using a first common mode voltage on a first point-to-point communication link of the plurality of point-to-point communication links, wherein the first point-to-point communication link is coupled between the central device and the central device;
- and
- send a second identifier to a second peripheral device of the plurality of peripheral devices using a second common mode voltage on a second point-to-point communication link of the plurality of point-to-point communication links, wherein the second point-to-point communication link is coupled between the second peripheral device and the central device.
