8.7 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.
