(1) Using the crystal oscillator (OSC1) mounted on the IE-703116-MC-EM1 as the internal clock
<1> If a crystal/ceramic resonator is mounted in the CN2 socket, remove it.
<2> Mount the 4.000 MHz crystal oscillator mounted at factory shipment in the OSC1 socket of the IE-703116-
MC-EM1 (with the default settings).
<3> Change JP1 as indicated in Table 2-2 (with the default settings).
<4> Set the SW1 and CKSEL pins according to the clock mode to be used, as shown in Table 2-2.
<5> To start up the integrated debugger (ID850), select “Internal” in the clock source selection area in the
configuration dialog box (clock selection in emulator).
