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 stops running. The CPU and the watchdog timer, operated by the CPU
clock, also stop. However, if the PM22 bit in the PM2 register is “1” (on-chip oscillator clock for the
watchdog timer count source), the watchdog timer remains active. Because the main clock, sub clock and
on-chip oscillator clock all are on, the peripheral functions using these clocks keep operating.

The microcomputer is placed into 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).
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 the ROCR3 to ROCR0 bits in the ROCR registers. 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 peripheral
function clocks. If the sub clock is on, f
