(1) Using the Oscillator Circuit on the Target System
When turning on the power supply, the internal clock of the emulation pod is selected to supply the
clock to the MCU. To use the external clock on the target system, change the clock by the CLK
command or the Init dialog on the emulator debugger. (For details, refer to the user's manual of the
emulator debugger.)

Notes on External Clock:
• To operate the emulation pod with an external clock, construct the oscillator circuit
as shown in Figure 3.3 in the target system and input the oscillator output at 50% duty
(within the operating range of the evaluation MCU) into pin X
should be open.
• Make note of the fact that in the oscillator circuit shown in Figure 3.4 where a
resonator is connected between pins X
a flexible cable, buffer IC and other devices are used between the evaluation MCU
and the target system. It is same for sub-clock oscillator circuits (X
