
All power supply lines can be interrupted by jumpers. This provides the
possibility to measure the current consumption of each individual power
domain of the device.

The IO supply voltage for the Mainboard (VDDIOF) can be connected via
jumper JP1 to Voltage1, if the PiggyBack board is mounted on a MainBoard.
