<Steps>
<1> Prepare the IE-78K0-NS-P04 Emulation Board.
<2> Remove the parts holder inserted in the socket (marked "X2") on the IE-78K0-NS-P04
Emulation Board.
<3> Connect the parts board (from <2> above) to the socket (X2) from which the parts holder
was removed. Insert the crystal oscillator into the socket so as to align the pins as shown
in the figure below.
