CRYSTAL OSCILLATION CIRCUIT
The figure below shows the connection example about general crystal resonator. The oscillation circuit has the
built-in feedback resistor (500kΩ) and oscillation stabilization capacitance (4 pF). Because the value of oscillation
stabilization capacitance must be adjusted to the most suitable value of individual oscillator, add the capacitance
(C1 and C2) to LSI external if necessary.
