Clock Settings
2.2.1 Clock settings outline
The following 4 clock setting methods are available.
For details, refer to
2.2.2 Clock setting methods
.
(1) Use the crystal oscillator mounted on OSC1 of the IE-703116-MC-EM1 as the internal clock (4.000 MHz).
(2) Change the crystal oscillator mounted on OSC1 of the IE-703116-MC-EM1 and use it as the internal clock
(other than 4.000 MHz).
(3) Mount a crystal/ceramic resonator and capacitor on CN2 of the IE-703116-MC-EM1 and use it as the internal
clock (other than 4.000 MHz).
(4) Use the crystal oscillator on the target system as the external clock (clock input from target system).
Caution
When using an external clock, input the clock generated by the crystal oscillator to the X1 pin.
When a clock generated by a crystal/ceramic resonator is used, the emulator does not operate
normally.
