Notes 1.
Select the clock source in the clock source selection area in the configuration dialog box on the
debugger.
2.
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 standalone basis.
Caution
Settings other than those described above are prohibited.
