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.
