(3) Mounting a crystal/ceramic resonator on the IE-703116-MC-EM1 and using it as the internal clock
<1> Mount the crystal/ceramic resonator and capacitor to be used in the CN2 socket as shown below (when
selecting the crystal/ceramic resonator, refer to the V850E/IA1 standards table).
<2> Set JP1 as shown in Table 2-4.
<3> Set the SW1 and CKSEL pins according to the clock mode to be used, as shown in Table 2-4.
<4> Select “Internal” in the clock source selection area in the configuration dialog box on the integrated debugger
(ID850).
