7.4.2 Disconnect Mode

Next to Shutdown Mode, the Disconnect mode is the lowest power state of the TUSB1002. The TUSB1002 enters this mode when exiting Shutdown mode. In this state, the TUSB1002 periodically checks for far-end receiver termination on both SSTX1 and SSTX2. Upon detection of the far-end receiver’s termination on both ports, the TUSB1002 transitions to a fully active mode called U0 mode.

When SLP_S0# is asserted low and the TUSB1002 is in Disconnect mode, the TUSB1002 remains in Disconnect mode and never perform far-end receiver detection. This allows even lower TUSB1002 power consumption while in the Disconnect mode. Once SLP_S0# is asserted high, the TUSB1002 again starts performing far-end receiver detection so it can know when to exit the Disconnect mode.
