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 XCIN
and XCOUT following the instruction.

Figure 2.5.6. Examples of Sub Clock Connection Circuit
(2) Sub Clock
The sub clock is generated by the sub clock oscillation circuit. This clock is used as the clock source for
the CPU clock, as well as the timer A and timer B count sources. In addition, an fc clock with the same
frequency as that of the sub clock can be output from the CLKOUT pin.
The sub clock oscillator circuit is configured by connecting a crystal resonator between the XCIN and
XCOUT pins. The sub clock oscillator circuit contains a feedback resistor, which is disconnected from the
oscillator circuit during stop mode in order to reduce the amount of power consumed in the chip. The sub
clock oscillator circuit may also be configured by feeding an externally generated clock to the XCIN pin.
Figure 2.5.6 shows the examples of sub clock connection circuit.
When the level on the START pin is “H ”, the sub clock is turned off after reset. At this time, the feedback
resistor is disconnected from the oscillator circuit.
To use the sub clock for the CPU clock, set the CM07 bit of CM0 register to “1 ” (sub clock) after the sub
clock becomes oscillating stably.
When a START pin is “L ”, the sub clock (XCIN) divided by 8 becomes the CPU clock after reset (the main
clock stops). When you use a main clock after this, please shift according to the procedure shown in Fig.
2.5.7.
During stop mode, all clocks including the sub clock are turned off. Refer to “power control”.
