2.5.1 Example of Oscillator Circuit
Figure 2.5.1 shows some examples of the main clock circuit, one using an oscillator connected to the
circuit, and the other one using an externally derived clock for input. Figure 2.5.2 shows some examples
of sub-clock circuits, one using an oscillator connected to the circuit, and the other one using an externally
derived clock for input. Circuit constants in Figures 2.5.1 and 2.5.2 vary with each oscillator used. Use
the values recommended by the manufacturer of your oscillator.

Note: Insert a damping resistor if required. The resistance will vary depending on the oscillator and the oscillation drive
capacity setting. Use the value recommended by the maker of the oscillator.
When the oscillation drive capacity is set to low, check that oscillation is stable. When being specified to connect a
feedback resistor externally by the manufacture, connect a feedback resistor between pins XIN and XOUT.
