NOTES:
1. See Figure 8.14.
2. When the CM17 bit is set to "1" (PLL clock as CPU clock source), set the CM17 bit to "0"(main clock as CPU clock source)
and the PLC07 bit is set to "0" (PLL off). Then enter wait mode or stop mode.
3. When the CM17 bit is set to "1" (PLL clock as CPU clock source), set the CM17 bit to "0"(main clock as CPU clock source)
and the PLC07 bit is set to "0" (PLL off). Then enter low-speed or low-power consumption mode.
