Port LED Indicators
This pin will be active low when LED support is enabled via EEPROM or
SMBus.
Port Swap Strapping Option
If this strap is enabled by package and configuration settings (see
"Hub Configuration
to determine the electrical connection polarity of the downstream USB port
pins (USB_DP and USB_DM).
Also, the active state of the LED will be determined as follows:
‘0’ = Port polarity is normal, LED is active high.
‘1’ = Port polarity (USB_DP and USB_DM) is swapped, LED is active low.
Enhanced Indicator Port LED for ports 4-7
Enhanced indicator LED for ports 4-7. This pin will be active low when LED
support is enabled via EEPROM or SMBus.
Enhanced Indicator Port LED for port 3
This pin will be active low when LED support is enabled via EEPROM or
SMBus.
Ganged Power and Over-current strap option
This signal selects between ganged or individual port power and over-current
sensing. If this strap is enabled by package and configuration settings (see
Table 8.1, "Hub Configuration
negation to determine the mode as follows:
‘0’ = Individual sensing and switching, LED_B_N[3] is active high.
‘1’ = Ganged sensing and switching, LED_B_N[3] is active low.
