2.6.6.7 Oscillation Characteristics
Oscillation characteristics change depending on conditions (board pattern, components used, etc.).
Use the following characteristics as reference values. In particular, when a ceramic or crystal
oscillator is used, use the oscillator manufacturer recommended values for constants such as
capacitance and resistance.
