Used for the port1 serial DSR
signal but can be reassigned as
GPIO input or output. If used
with the development board, this
pin maps to GPIO-3.
Used for the port 1 serial CTS
signal but can be reassigned as
GPIO input or output. If used
with the development board, this
pin maps to GPIO-2.
Used for the port 1 serial DCD
signal but can be reassigned as
GPIO input or output. If used
with the development board, this
pin maps to GPIO-1.
Used for port 2 serial transmit but
can be reassigned as GPIO input
or output. If used with the
development board, this pin maps
to GPIO-8.
Used as the power indicator
(always on) but can be reassigned
as a general purpose LED. It must
remain a GPIO output for the
LED to operate correctly. This
LED is lit when the signal is low.
Should be configured as a GPIO
input.
