General Purpose I/O data: These three
general-purpose signals are fully programmable
as either push-pull output, open-drain output or
input by writing the GPIO_CFG configuration
register in the CSR’s. They are also multiplexed
as GP LED connections.
GPIO signals are Schmitt-triggered inputs.
When configured as LED outputs these signals
are open-drain.
nLED1 (Speed Indicator). This signal is driven
low when the operating speed is 100Mbs,
during auto-negotiation and when the cable is
disconnected. This signal is driven high only
during 10Mbs operation.
nLED2 (Link & Activity Indicator). This signal
is driven low (LED on) when the LAN9210
detects a valid link. This signal is pulsed high
(LED off) for 80mS whenever transmit or
receive activity is detected. This signal 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 flash as an
activity indicator.
nLED3 (Full-Duplex Indicator). This signal is
driven low when the link is operating in full-
duplex mode.

+1.8 V from internal core regulator. Both pins
must be connected together externally. Each
pin requires a 0.01uF decoupling capacitor. In
addition, pin 2 requires a bulk 4.7uF capacitor
(<2 Ohm ESR) in parallel. These pins must not
be used to supply power to other external
devices. See
