8.4.4 High-Speed Downstream Port Electrical Compliance Test Mode

TUSB217A will detect HS compliance test fixture and enter downstream port high-speed eye diagram test mode. CD pin will be low and ENA_HS pin is asserted high when TUSB217A is in HS eye compliance test mode.

If RSTN pin is asserted low and de-asserted high while TUSB217A is operating in HS functional mode, TUSB217A may transition to HS eye compliance test mode and CD asserts low and ENA_HS remains high. When this occurs signal compensation is enabled.
