5V or 3.3V power supply must be used.
The following jumpers affect the power supply pins of the MPC560xP
processor:
J3 – Power Supply Voltage Selection
Controls whether the processor is powered using 5V or 3.3V. This selection
can only be made if the xPC560P Mini-Module is plugged into the
xPC56XXMB motherboard. If the xPC560P 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.
J4 – ADC Analog Supply Voltage Enable
Controls whether the reference voltage and analog supply pins for the A/D
converter (VDD-REF ADC0, VDD-REF ADC1) is powered by 5V or 3.3V
