4.2 Voltage distribution
The table shows the required device power supply pins and their function:
Supply for the device internal regulators for the digital logic.
Supply for ports of AWO area.
Supply for ports and analog functions of ADC0.
IO supply voltage for components located on a connected
mainboard.
• For each of the above voltages, the voltage source can be selected from
Voltage1 (typ. 5.0V) or Voltage2 (typ. 3.3V) by the jumpers JP0, JP1, JP2,
JP4, JP9 and JP6.
