3.3 Selecting a Clock Supplied to an MCU
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.
Table 3.1 Clock supply to the MCU
(1) How to Select a Clock Supplied to an MCU
Change a 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.
