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.
The sub clock oscillator circuit is configured by connecting a crystal resonator between the X
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 X
7.2.1 shows the examples of sub clock connection circuit.
After reset, the sub clock is turned off. 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 in the CM0 register to “1 ” (sub clock) after the sub
clock becomes oscillating stably.
During stop mode, all clocks including the sub clock are turned off. Refer to 7.6 Power Control.
