Mounting the FK3 device on the board

The AB-050-FX3-U boards is shipped with a mounted V850ES/FK3 device.
Nevertheless, if mounting of another V850ES/FK3 device is required at a later time the following guideline is
supplied:
To mount a FK3 device on the AB-050-FX3-U place the package in the top right corner of the SMD area.
As the FK3 with 176 pins is placed on an SMD area with 180 pins 4 pads will not be used. Due to the alignment of
the device in the top right corner two pads in the lowest line and two pads in the left most line remain empty.
Therefore align pin 1 of the device with pin 2 of the SMD pad area.
For details see Figure 3-1 and Figure 3-2.
