3.5 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.

(1) Selecting Clock Supply
To select the clock supply, change the clock by the Clock tab of the Init dialog box when starting up
the emulator debugger or the CLK command input on the Script Window. For details, refer to user's
manual of the emulator debugger.
