Chapter 3. Setting Up
3.1 Selecting Clock Supply
There are two ways to supply a clock to the MCU, using the oscillator circuit of the emulator or using
the oscillator circuit on the target system. Table 3.1 lists the factory-settings of each clock supply.

IMPORTANT
Notes on Changing the Clock Supply:
• The clock supply can be set by the Init dialog box when starting up the emulator
debugger or inputting CLK command on the script window.
• For XCIN-XCOUT, it is necessary to set switches in the emulator. For details, refer to
"3.5 Setting Switches" (page 31).
