This pin is driven low (LED on) when a valid link is
detected. This pin is pulsed high (LED off) for
80mS whenever transmit or receive activity is
detected. This pin is then driven low again for a
minimum of 80mS, after which time it will repeat
the process if TX or RX activity is detected.
Effectively, LED2 is activated solid for a link. When
transmit or receive activity is sensed, LED2 will
function as an activity indicator.
This General Purpose I/O pin is fully programmable
as either a push-pull output, an open-drain output,
or a Schmitt-triggered input.
This pin is driven low (LED on) when the Ethernet
operating speed is 100Mbs, or during auto-
negotiation. This pin is driven high during 10Mbs
operation, or during line isolation.
This General Purpose I/O pin is fully programmable
as either a push-pull output, an open-drain output,
or a Schmitt-triggered input.

This General Purpose I/O pin is fully programmable
as either a push-pull output, an open-drain output,
or a Schmitt-triggered input.
This pin detects the state of the upstream bus
power. The Hub monitors VBUS_DET to determine
when to assert the USBDP0 pin's internal pull-up
resistor (signaling a connect event).
For bus powered hubs, this pin must be tied to
VDD33IO.
For self powered hubs where the device is
permanently attached to a host, VBUS_DET should
be pulled to VDD33IO. For other self powered
applications, refer to the device reference
schematic for additional connection information.
Determines the default Auto-MDIX setting.
0 = Auto-MDIX is disabled.
1 = Auto-MDIX is enabled.
