Settings
2.2.1 Outline of clock settings
The following three clock setting methods are available.
For details, refer to
2.2.2 Clock setting methods
.
(1) Use the crystal oscillator mounted on the IE-703107-MC-EM1 as the internal clock.
(2) Change the crystal oscillator mounted on the IE-703107-MC-EM1 and use it as the internal clock.
(3) Use the crystal oscillator on the target system as an external clock.
Caution When using an external clock, input a square wave to the X1 pin.
When a clock generated by a crystal/ceramic resonator is used, the IE-703107-MC-EM1 does not
operate.
