1. When the CM05 bit is set to 1 (main clock turned off) in low-speed mode, the mode goes to low power
2. The divide-by-n value can be selected the same way as in on-chip oscillator mode.
3. On-chip oscillator frequency can be any of those described in the section 7.6.1.6 On-chip Oscillator Mode.

In wait mode, the CPU clock is turned off, so are the CPU (because operated by the CPU clock) and the
watchdog timer. However, if the PM22 bit in the PM2 register is 1 (on-chip oscillator clock for the watch-
dog timer count source), the watchdog timer remains active. Because the main clock, sub clock, on-chip
oscillator clock and PLL clock all are on, the peripheral functions using these clocks keep operating.

The selected on-chip oscillator clock divided by 1 (undivided), 2, 4, 8 or 16 provides the CPU clock.
The on-chip oscillator clock is also the clock source for the peripheral function clocks. If the sub clock
is on, f
selected by bits ROCR3 to ROCR0 in the ROCR register. When the operation mode is returned to the
high and medium speed modes, set the CM06 bit to 1 (divided by 8 mode).
The main clock is turned off after being placed in on-chip oscillator mode. The CPU clock can be se-
lected as in the on-chip oscillator mode. The on-chip oscillator clock is the clock source for the periph-
eral function clocks. If the sub clock is on, f

remains active.
The MCU enters wait mode by executing the WAIT instruction.
When the CM11 bit is set to 1 (CPU clock source is the PLL clock), be sure to clear the CM11 bit to 0
(CPU clock source is the main clock) before going to wait mode. The power consumption of the chip
can be reduced by clearing the PLC07 bit to 0 (PLL stops).
