General Information

LEDs
Reset
The embedded modules have two types of LEDs:
The development kit, by default, correctly configures the GPIO connected to the LED as an
output and then uses this LED to represent Ethernet activity.
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 0.8v, for one
microsecond. When plugged into a development board, this pin is wired to the push button
at SW4. As a result, this switch acts as a hard reset button.
An LED connected directly to GPIO pins on the processor and controlled

hardware) and not directly programmable by the operating system
