3.1.3 Using the Oscillator Circuit on the Target System
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
IN
. And pin X
OUT
should be open. Choose "External" in the emulator
debugger to use this clock.
Figure 3.5 External oscillator circuit
Make note that in the oscillator circuit shown in Figure 3.6 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
).
