Abstract
A first portion of a communication link is operated in a power savings mode at the same time that a second portion of the communication link is operated in a normal operational mode. For the first portion, a refresh mode is entered from the power savings mode in which one or more training patterns are transmitted over the first portion, while the second portion remains in the normal operational mode. An indication when to activate and deactivate the refresh mode may be sent over the second portion of the communication link. The refresh mode may be periodically entered from the power savings mode based on an interval register specifying the amount of time the communication link should remain in the power savings mode before a refresh occurs. In addition, the amount of time spent in the refresh mode may be programmable.
