SYSTEMS, APPARATUSES, AND METHODS FOR SYNCHRONIZING PORT ENTRY INTO A LOW POWER STATUS

摘要

Systems, apparatuses, and method for synchronizing port entry into a lowest power state are described. All logic of a port placed into an intermediate state prior to entry into the lowest power state.

1. An apparatus comprising:
a transmitter; a receiver; a power controller to transition the transmitter and the receiver to a low power state, wherein the power controller to transition the transmitter and the receiver to a low power state, the power controller operable to
halt a data transfer rate state of a device;transition the receiver and the transmitter to a first power saving state in response to the data transfer rate state being halted;in response to the receiver and the transmitter being in the first power saving state, transition the receiver to a second power saving state in which configuration state for the first receiver and the first transmitter is maintained, the second power saving state being a lower power consumption state than the first power saving state;in response to the receiver transitioning to the second power saving state that is to maintain configuration state for the receiver and the transmitter, transition the transmitter to the second power saving state.
