Clock Generating Circuit
The clock generating circuit contains two oscillator circuits that supply the operating clock sources to the
CPU and internal peripheral units.
Example of oscillator circuit
Figure 1.15 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 1.16 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 15 and 16 vary with each oscillator used. Use the values
recommended by the manufacturer of your oscillator.

(Note)
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. Also,
if the oscillator manufacturer's
data sheet specifies that a
feedback resistor be added
external to the chip, insert a
feedback resistor between XIN
and XOUT following the
instruction.
