The embedded modules have two types of LEDs:
The development kit, by default, correctly configures the GPIO connected to the LED
(PORTC6) as an output and then uses this LED to represent Ethernet activity. For more
information regarding the control of LEDs, see the Net+Works with GNU Tools BSP
Porting Guide.
The embedded module supports a hardware reset via pin 14 of the 20-pin header. The unit
is forced into a hard reset when pulling the pin to ground, or less than 2.88v, for one
microsecond. When plugged into a development board, this pin is wired to the push button
at SW3. As a result, this switch acts as a hard reset button.
Yellow
An LED connected directly to GPIO pins on the processor and controlled
directly in software
An LED connected to other hardware components (normally the Ethernet
hardware) and not directly programmable by the operating system
LED
Green
This is wired directly to Ethernet hardware and provides an indication of link.
This software programmable LED is wired to processor GPIO register bit PORTC6
and is wired to be lit when low. The default behavior is to blink on Ethernet activity.
