by measuring the current that is flowing into this plane. The VCC_MCU_P3V3 plane 
is connected via a jumper to the main power plane (VCC_P3V3) and by replacing the 
jumper with an amperemeter it is possible to determine the current consumption. To 
locate the power measurement header, please refer to
 
WARNING 
Do not power the board without having the jumper or an amperemeter 
mounted since this can cause latch-up of the Atmel AVR 
ATxmega256A3BU due to current flow into the I/O pins. 
3.4 Programming the kit 
The kit can be programmed either from an external programming tool or through an 
USB boot loader which is pre-programmed on the device. 
The boot loader is evoked by pushing the push button (SW0) during power-on, that is 
push and hold the button and hence connect an USB cable to the kit. Programming 
can be performed through the DFU programmer FLIP. 
How a programmer can be connected to the kit is described in Section
