(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
IN
. And pin X
OUT
should be open.
It is same for sub-clock oscillator (X
CIN
and X
COUT
).
Figure 3.1 External oscillator circuit
Make note of the fact that in the oscillator circuit shown in Figure 3.2 where a resonator is connected
between pins X
IN
and X
OUT
, oscillation does not occur because an emulation circuit is used between
the evaluation MCU and the target system. It is same for sub-clock oscillator circuits (X
CIN
and
X
COUT
).

)
IMPORTANT
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
IN
. And pin X
OUT
should be open.
• Make note that in the oscillator circuit shown in Figure 3.2 where a resonator is
connected between pins X
IN
and X
OUT
, oscillation does not occur because 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
CIN
and X
COUT
).
