7.3.6 Receiver Detect Control

The SLP_S0# pin offers system designers the ability to control the TUSB1104 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 TUSB1104 receiver detect functionality. While SLP_S0# is asserted low and USB 3.2 interface is in U3, the TUSB1104 keeps receiver termination active. The TUSB1104 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 TUSB1104 is in Disconnect state when SLP_S0# is asserted low, then TUSB1104 disables all channels receiver termination and disables receiver detect functionality. When SLP_S0# is asserted high, the TUSB1104 resumes normal operation of performing far-end receiver termination detection.

Note: As there is a single SLP_S0# pin, this pin when asserted low impact both port 1 (CRX1, CTX1, SSRX1, SSTX1) and port 2 (CRX2, CTX2, SSRX2, SSTX2).
