ABSTRACT:
A computer system includes a first and a second integrated circuit coupled by a communication link. The communication link operates in a power savings mode in which data is not transmitted over the link. Periodically, the communication link enters a training phase in which training patterns are transmitted over the communication link for a predetermined time period. The communication link returns to the power savings mode after the predetermined time period has elapsed. At least one sideband signal, separate from the communication link, and coupled between the first and second integrated circuits, is used to indicate when to enter the training phase from the power savings mode and exit the training phase and return to the power savings mode.
