Power Supply
The evaluation board uses an external 3.3V regulated supply (included with kit). The
evaluation board contains additional filtering and protection.
General Control PLD
The following table denotes the configuration of the evaluation board. Configuring
the jumper re-routes the signals on the evaluation board as required for a given
product. This also drives the LEDs.
