Figure 2.1 External oscillator circuit
Make note that in the oscillator circuit shown in Figure 2.2 where a resonator is connected between pins X
IN
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
COUT
).
