8.2.5.1.2.11 USB 2.0 Port Indicator LED Terminals

Table 8-3 Port State to Port Indicator Color Mapping

Power Switching	Downstream Facing Hub Port State
Power Switching	Powered-Off	Disconnected, Disabled, Not Configured, Resetting, Testing	Enabled, Transmit, Receive	Suspended, Resuming, Restart
With	Off or amber if over-current	Off	Green	Off
Without	Off	Off or amber if over-current	Green	Off

PORTINDZ_SMBA3 – Individual USB 2.0 port indicator LEDs are enabled and reported in the USB descriptors when a 4.7-kΩ pull-down is placed on this terminal and sampled at power-on reset. The TUSB8040A1 has an internal pull-up on this terminal. The TUSB8040A1 defaults to the lower cost implementation without the port LEDs. This pin also acts as the interface for the SMBA3 signal when a SMBus host is connected to the TUSB8040A1.
LEDA0Z_RMBL0 – Removable device mode on port 0 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 0 is reported in the USB descriptors as a non-removable port with a permanently attached device. After reset, this signal acts as the active low USB 2.0 port indicator status amber LED for port 0.
LEDG0Z_USED0 – Port 0 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 0 will not be an active port. After reset, this signal acts as the active low USB 2.0 port indicator status green LED for port 0.
LEDA1Z_RMBL1 – Removable device mode on port 1 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 1 is reported in the USB descriptors as a non-removable port with a permanently attached device. After reset, this signal acts as the active low USB 2.0 port indicator status amber LED for port 1.
LEDG1Z_USED1 – Port 1 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 1 will not be an active port. After reset, this signal acts as the active low USB 2.0 port indicator status green LED for port 1.
LEDA2Z_RMBL2 – Removable device mode on port 2 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 2 is reported in the USB descriptors as a non-removable port with a permanently attached device. After reset, this signal acts as the active low USB 2.0 port indicator status amber LED for port 2.
LEDG2Z_USED2 – Port 2 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 2 will not be an active port. After reset, this signal acts as the active low USB 2.0 port indicator status green LED for port 2.
LEDA3Z_RMBL3 – Removable device mode on port 3 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 3 is reported in the USB descriptors as a non-removable port with a permanently attached device. After reset, this signal acts as the active low USB 2.0 port indicator status amber LED for port 3.
LEDG3Z_USED3 – Port 3 is enabled by default via the internal pull-up resistor on this terminal. If a 4.7-kΩ pull-down is placed on this terminal and sampled at power on reset, port 3 will not be an active port. After reset, this signal acts as the active low USB 2.0 port indicator status green LED for port 3.
