8.4.6 L2 State Interrupt Modes

To prevent signaling on eUSB2 while the eDSP is powered off, make sure both L2 remote wake interrupt and disconnect event interrupt modes are enabled. The special remote wake sequence when L2 remote wake interrupt mode is enabled.

  • System enables interrupt USB_REMOTE_WAKE_P1.
  • Repeater is in host mode and has received a CM.L2.
  • Repeater detects wake on USB 2.0
  • Repeater asserts interrupt.
  • Repeater reflects resume on USB 2.0, but does not signal wake on eUSB2.
  • Repeater waits for eDSPr to signal start of resume with no intervening configuration, connect, or reset sequence.
  • Repeater and eDSP follow normal eUSB2 protocol to signal resume starting and ending in L0.

The special wake on disconnect sequence when disconnect event interrupt mode is enabled

  • System enables interrupt USB_DISCONNECT_P1.
  • Repeater is in host mode and has received a CM.L2.
  • Repeater detects SE0 for disconnect on USB 2.0.
  • Repeater asserts interrupt.
  • Interrupt must be cleared prior to eDSPr reinitializing the TUSB2E11 as a host.
  • Repeater does not signal or report USB 2.0 SE0 on eUSB2.
  • Repeater waits for eDSPr to power up, which starts with port reset announcement.
  • Repeater and eDSP follow normal eUSB2 protocol, ending in unconnected state of host mode.
