Selection
Controls whether the processor is powered using 5V or 3.3V. This selection
can only be made if the xPC560B Mini-Module is plugged into the
xPC56XXMB motherboard. If the xPC560B Mini-Module is used as a stand-
alone board, the processor is powered directly by the external power supply
and this jumper setting has no effect.
