Abstract
In some embodiments, a method for supporting multiple devices on a high speed physical link may be described. An embedded device may assert a link request pin to request to transmit data on a multi-point communications link that may serve a plurality of embedded devices. A controlling device may receive the link request signal. When the controlling device finishes sending data on the link, it may address the plurality of embedded devices in a round robin format and may determine which device asserted the link request pin. The embedded device that asserted the link request pin may send an acknowledgement signal to the controlling device when it is addressed.
