+
+The ABNT CODI is an old energy meter standard used in Brazil.
+
+This code interprets the end user serial output existent in the energy meter.
+That output externalizes its data blinking an LED as a serial protocol at the
+baudrate of ``110 BPS`` and uses ``8`` octects:
+
+=======   =======   =================================================================
+Octet     Bits      Description
+=======   =======   =================================================================
+``001``   ``0-7``   Number of seconds to the end of current active demand (``LSB``)
+``002``   ``0-3``   Number of seconds to the end of current active demand (``MSB``)
+          ``4``     Bill indicator. It is inverted at each demand replenishment
+          ``5``     Reactive Interval Indicator. Inverted at end react interval
+          ``6``     If ``1`` means the reactive-capacitive is used to calculate ``UFER``
+          ``7``     If ``1`` means the reactive-inductive is used to calculate ``UFER``
+``003``   ``0-3``   Current seasonal segment:  ``0001`` – tip, ``0010`` – out of tip, ``1000`` – reserved
+          ``4-5``   Type of charging indicator (flag): ``00`` – Blue, ``01`` – Green, ``10`` – Irrigators, ``11`` – Other
+          ``6``     Not used
+          ``7``     If equal ``1`` means reactive rate is enabled
+``004``   ``0-7``   Number of pulses for active energy of cur dem interv (``LSB``)
+``005``   ``0-6``   Number of pulses for active energy of cur dem interv (``MSB``)
+          ``7``     Not used
+``006``   ``0-7``   Number of pulses for reactive energy of cur dem interv (``LSB``)
+``007``   ``0-6``   Number of pulses for reactive energy of cur dem interv (``MSB``)
+          ``7``     Not used
+``008``   ``0-7``   Inverted bits of _xor_ from previous octects
