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 Figure 3-1.

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 4.1.
