3.3 Selecting Clock Supply and Replacing Oscillator Circuit Boards
(1) Clock Supply to the MCU
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 3.1 lists the factory-settings of each clock
supply. The clock supply can be set in the Init dialog box when starting up the emulator debugger or
inputting CLK command on the script window.
