Used as the NET+OS green LED
but can be reassigned as a general
purpose LED. It must remain a
GPIO output for the LED to
operate correctly. The LED is lit
when the signal is low.
Used for port 2 serial receive but
can be reassigned as GPIO input
or output. If used with the
development board, this pin maps
to GPIO-9.
Used as the NET+OS yellow
LED but can be reassigned as a
general purpose LED. It must
remain a GPIO output for the
LED to operate correctly. The
LED is lit when the signal is a
