3.3 Selecting Clock Supply
There are two ways to supply a clock to the MCU, using the oscillator circuit of the emulation pod
or using the oscillator circuit on the target system. Table 3.4 shows the factory-settings of each clock
supply.

IMPORTANT
Notes on Changing the Clock Supply:•The clock supply can be set by the Init dialog when starting up the emulator debugger
or inputting CLK command on the script window.
•For XCIN-XCOUT pins, it is necessary to set switches in the emulation pod when using
the clock on the target system. For details, refer to "3.2 Switch Settings" (page 25).
