■ OSCILLATION CIRCUIT
The figure below shows the connection example about general resonator. The oscillation circuit has the built-in
resistance (1 MΩ) . The value of capacity (C1 and C2) is required adjusting to the most suitable value of individual
resonator.
The most suitable value is different by individual resonator. Please refer to the resonator manufacturer which
you use for the most suitable value.
Input the clock to XIN pin, and do not connect anything with XOUT pin if you use the external clock (you do not
use the resonator).
