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 3.2 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 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. For details,

refer to "3.2 Switch Settings" (page 25).
