(2) Using the Oscillator Circuit on the Target System
To operate the compact emulator with the oscillator circuit on the target system, construct the
oscillator circuit as shown in Figure 3.1 in the target system and input the oscillator output at 50%
duty (within the operating range of the evaluation MCU) into pin X
It is same for sub-clock oscillator (X

Notes on Operating an Oscillator Circuit on the Target System:
• To operate this product with an external clock, construct the oscillator circuit as
shown in Figure 3.6 in the target system and input the oscillator output at 50% duty
(within the operating range of the evaluation MCU) into pin X

• Make note that in the oscillator circuit shown in Figure 3.2 where a resonator is
connected between pins X
