(5) Using the Oscillator Circuit on the User System

To operate this product with an external clock, construct the oscillator circuit as shown in Figure 2.22 in the user system and

input the oscillator output at 50% duty (within the operating range of the evaluation MCU) into pin X

. And pin X

OUT

should

be open. Choose "External" in the emulator debugger to use this clock.

Figure 2.22 External oscillator circuit

Make note that in the oscillator circuit shown in Figure 2.23 where a resonator is connected between pins X

and X

OUT

oscillation does not occur because a flexible cable, buffer IC and other devices are used between the evaluation MCU and the

user system. It is same for sub-clock oscillator circuits (X

CIN

and X
