(1) Using the crystal oscillator (OSC) mounted on the IE-703107-MC-EM1 as the internal clock
<1> Mount the 5.000 MHz crystal oscillator mounted at factory shipment in the OSC socket of the IE-703107-
MC-EM1 (with the default settings).
<2> Change JP1 as indicated in Table 2-2 (with the default settings).
<3> Set the SW1 and CKSEL pins according to the clock mode to be used, as shown in Table 2-2.
<4> To start up the integrated debugger (ID850), select “Internal” in the clock source selection area in the
configuration dialog box (clock selection in emulator).

The input setting to the CKSEL pin is made only when a target system is connected.
Leave this pin open when operating the emulator on a stand-alone basis. The emulator operates according
to the setting of SW1.
