3.3 Using the Oscillator Circuit on the Target System
To operate this product with an oscillator circuit of the target system, input the oscillator output at
50% duty (within the operating range of the evaluation MCU) into pin X
Pin X
Figure 3.5 External oscillator circuit
In the oscillator circuit shown in Figure 3.6 where a resonator is connected between pins X
oscillation does not occur because a converter board is used between the evaluation MCU and the
target system.

Notes on External Clock:
should be open. Choose "External" in the emulator debugger to use this clock.
OUT
• To operate this product with an external clock, construct the oscillator circuit as
shown in Figure 3.5 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 3.6 where a
resonator is connected between pins X
a converter board and other devices are used between the evaluation MCU and the
target system. It is same for sub-clock oscillator circuits (X
