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.
Note:
Note:
Detects state of upstream bus power.
For bus powered applications, this pin must be
tied to VDD33IO.
For self powered applications 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.
Note:
This pin must always be connected to VDD33IO
for proper operation.
This pin must always be connected to VSS for
proper operation.
This pin must always be connected to VSS for
proper operation.
(LAN9500A/LAN9500Ai only)
This pin may serve as a wakeup pin
whose detection mode is selectable
when External PHY and PME modes of
operation are in effect. Refer to
Chapter 6, "PME Operation," on
page 40
By default this pin is configured as a
GPIO.
(LAN9500A/LAN9500Ai only)
This pin may be used to signal bus
power availability when PME mode of
operation is in effect. Refer to
Chapter 6, "PME Operation," on
