Flat Panel Display Connector (CN10):
CN10 is a 40-pin connector, Hirose DF13A-40DP-1.25V, which can support a 24-bit LCD panel.
A bias control signal, ENVEE, active high on CN10, controls the LCD bias voltage. The LCD bias
voltage shall not be applied until the +5V or +3.3V logical supply and panel video signals become
stable. When powered on, the control signal remains low until receiving the flat panel signals.
