•
Pass-through Mode – Any board port becomes a transparent channel, which passes through all input data
to another port of your choice with or without interpretation of input data. Furthermore, a bidirectional
transparent channel which passes through all input data from one port to another and vice versa can easily
be established.
•
Universal Break Sequence – Never have your board locked up because of unresponsive ports.
•
Sleep mode – Minimize power consumption by putting the board in a dormant state and awake it up at a
specified GPS time.
