LED display
The ST802RT1x supports three configurable light emitting diode (LED) pins. The three
supported LED configurations are: link, speed, activity and collision. Functions are
multiplexed among the LEDs according to the LED mode selected through bit 9 of the
Auxiliary mode 2 register (RN1B[9]). Since these LED pins are also used as strap options,
the polarity of the LED is dependent on whether the pin is pulled up or down.
