7 ELECTRICAL CHARACTERISTICS
7.7 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 oscillator is used for OSC3, use
the oscillator manufacturer’s recommended values for constants such as capacitance and resistance. The
oscillation start time is important because it becomes the wait time when OSC3 clock is used. (If OSC3 is
used as CPU clock before oscillation stabilizes, the CPU may malfunction.)
