Figure 1.19 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 1.20 shows some examples of subclock circuits, one using
an oscillator connected to the circuit, and the other one using an externally derived clock for input. Circuit constants in
Figure 1.19 and Figure 1.20 vary with each oscillator used. Use the values recommended by the manufacturer of your
oscillator.

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. Also, if the oscillator manufacturer's
data sheet specifies that a feedback resistor be added external to the chip, insert a feedback resistor between X
and X
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.
