7.3.4 Receiver Detect Control

The SLP_S0# pin offers system designers the ability to control the TUSB1002 Rx.Detect functionality during Disconnect and U2/U3 states and therefore achieving lower consumption in these states. When the system is in a low power state (Sx where x = 1, 2, 3, 4, or 5), system can assert SLP_S0# low to disable TUSB1002 receiver detect functionality. While SLP_S0# is asserted low and USB 3.1 interface is in U3, the TUSB1002 keeps receiver termination active. The TUSB1002 will not respond to any LFPS signaling while in this state. This means that system wake from U3 is not supported while SLP_S0# is asserted low. If the TUSB1002 is in Disconnect state when SLP_S0# is asserted low, then TUSB1002 disables both channels receiver termination. When SLP_S0# is asserted high, the TUSB1002 resumes normal operation of performing far-end receiver termination detection.
