The controller implements one output driver
per port intended for driving external LED
circuits. LED outputs can be individually
configured to select the particular event,
state, or activity, which is indicated on that
output. In addition, each LED can be
individually configured for output polarity as
well as for blinking versus non-blinking
(steady-state) indication.
