Figure 4.5 External oscillator circuit

Figure 4.6 Circuit in which oscillation does not occur

(2) Using target system's oscillator

a. To operate the emulator with an external clock, construct the oscillation circuit shown in

Figure 4.5 in the target system and input the oscillation output at 40-60% duty into the Xin

(Xcin) pin.

b. Make note of the fact that in the oscillation circuit shown in Figure 4.6 where a resonator

is connected between the Xin (Xcin) and Xout (Xcout) pins, oscillation does not occur

because a flexible cable, buffer IC and other devices are used between the evaluation MCU

and the target system.
