    1.1.1 Overview The LAN9514 is a high performance Hi-Speed USB 2.0 hub with a 10/100 Ethernet controller. With applications ranging from embedded systems, desktop PCs, notebook PCs, printers, game consoles, and docking stations, the LAN9514 is targeted as a high performance, low cost USB/Ethernet and USB/USB connectivity solution.

    1.1.5 Peripherals The LAN9514 also contains a TAP controller, and provides three PHY LED indicators, as well as eight general purpose I/O pins. All GPIOs can serve as remote wakeup events when LAN9514 is in a suspended state. The integrated IEEE 1149.1 compliant TAP controller provides boundary scan via JTAG.

    Port Power Control Using a USB Power Switch The LAN9514 has a single port power control and over-current sense signal for each downstream port. When disabling port power the driver will actively drive a ‘0’. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time.
